There is a song by beck that describes them perfectly.

same here im currently watchin this on a 47 in vizio i repaired videos likes this helpd me out when it finally comes on after looking for the problem that feeling kinda feels like elation lol

The thumbs-down's come from cats, who feel that this guy's cat got insufficient exposure on this video.

Trolls will be trolls. Could be someone that runs a shop. I am sure that are professional techs lurking here looking for information to boost their business. Come here to see what goes wrong and then thumb down the work because they cant stand someone informing their customers what goes wrong so they cant charge an arm and leg. Same goes when I showed how to snake a clogged drain using an 18.00 rental auger snake. Plumbers will be pissed off because for everyone that now knows how to do it, that is 1 less customer willing to pay them 200+ to come out and do the same thing.

The Beatles had Beck beat by 40 years. Except they didn't suggest that someone kill them.

Yup. Nose eyes and ears.

Love my plasma sets. I have 1 led set, a 4k and seldom turn it on. I think I use the old crt set more than the led. Use it only for checking 4k content before I upload.

That's a good one. Well I have an LED set, I use at my shop. I like it. Once I saw the plasma, holly crap, its like a crt hi def plus. Really bright and brilliant colours. Any info on the Philipps? I think its 52".

@@markanderson350 LED/LCD are light sources with an LCD "shutter" to restrict the light. Plasma (and OLED) are tiny points of light generated by the panel. OLED uses organic LEDs and plasma each pixel is essentially a tiny fluorescent lamp.

It really wasn't that simple. I was disconnecting one circuit at a time. The 15 volt rail goes to sc board via the a, it also goes to the ss board and to a board on multiple lines. Pin 1 and 2 on the connector goes to audio amp. You can see I cut those first and then reconnected and taped them when I moved to pin 3 to isolate short. Then disconnected flat jumper wire that runs from a board to sc board. This repair was spread over 2 days.

@@12voltvids youssefD

Well i am trying to limit how much i work on these days. Pretty much sticking to vintage audio and some video. I look at the stats and audio brings in the views, thus money, camcorders, tv and VCR not so much. So if there is little fibiancial gain for the video then i question why bother and that affects my decision to make a video, or to put a huge amount of effort into it. Vintage audio on the other hand views take off so that is what I put more effort into.

Nope current sensing. Very low ohms. Like a fuse resistor. Once I blew up the schematic I could see the current sensing loop which fires a transistor that feeds back to the power supply micro that shuts everything down.

Taking a shot over the bow at anyone in particular?

Remember I know nothing about these new TVs.

@Martin P. I am serious when I say I know little about plasma TV. I did take a course in 2002 but that was board replacement only. I just use common sense troubleshooting. Isolate and conquer. Everything I know about plasma TV I learned myself. I pass this on in the hope that others will get something out of it. At least people are interested in fixing plasma sets because you can't buy them anymore. They are also the most complex of all the TVs. LCD and oled are pretty much non serviceable as much of the signal processing is in the panel itself.

Hi 12 volt vids... I have the exact same problem with a Panasonic TH-P50U20Z. I can't find the service manual anywhere. Is it possible for you to email me the service manual for the 46 inch? The boards and the layout appear to be the same. Cheers V3FMRADIO@OUTLOOK.COM

Plasma TVs just have to be saved. They were the last sets that had some good engineering in them, especially Panasonic sets. I now have 5 functional Panasonic and 1 to fix.

I have 5 spare plasma sets. A 42 lg. The rest are Panasonic. 42 thx certified. 46 and 50, plus a 50 monitor with separate signal box. Those are spare sets. I currently use a 42 Panasonic on my edit suite and have samsung 63 in my media room. My bedroom 50 samsung is all burned in from the local tv station logo during the morning snews.

@@12voltvids I may die watching a plasma set...

Too many. Had this been a paid repair I would have probably charged 150 to fix this. The video runs only what 25 minutes, but it actually took me about 4 hours to find the problem, but as I showed in the video, only 1 part was changed. I showed all the steps in servicing, but spent much time studying the schematic on the computer, and I tell you this is a bloody complex circuit.

@@12voltvids lol You did what mostly anyone else would've given up on. If a board couldn't be obtained.

@@timka880057 Well I look to see if it can be fixed. When I was in the business everything was component level repair. No boards available, except for zenith. They used modules but we preferred to repair those too. I certainly don't miss those days.

@@12voltvids When I was a kid I loved watching an old tv repair guy replace compnents under the chasis of an old RCA color TV my brother had. It was very interesting in those days to see it come back to life again just for a few components replaced. I remember it was some old carbon resistors that was open or changed value... or a shorted capacitor and a few old tubes replaced. I miss that!

Lots are junked for simple fixes. These plasma panels should be good for 100000 hours of use.

I think so, but 7 so far don't. Those 7 are probably the same ones that tells the receipt checker ot Walmart or Costco to go f--k themself.

To find a short like that, you give it power from an external current limited supply. Then you look for hot spots. Alcohol works, or freeze spray, or IR camera.

Don't overlook those nasty ceramic caps.

I'm watching my plasma now. Still using them here. They have a great picture.

37 was the smallest of the plasma sets and wasn't as popular as larger ones. Same with the 46. 42 was very popular as was the 50. The reason was there wasn't much of a price difference between the 37 and 42, just like there wasn't much difference between 46 and 50, so the larger one was more popular.

@@12voltvids Indeed, I think we initially chose it because of the reduced day-to-day power consumption over the larger models. Also, like a lot of British homes, our lounge is quite small, so it seemed to make more sense considering ten years ago HD content was not as prevalent as it is these days. Replacing a CRT before it made it ideal for what was (for us) mostly standard-def viewing back then, anyway. Oh if only it had been a full HD plasma like your one, we probably still be watching it! ;)

@@Oldgamingfart There are some pretty small pads here too. With the high cost of land here micro homes under 300 sq feet are springing up in lane ways. My place would have been considered pretty small a few years ago and it is 2500 sq feet.

@@Oldgamingfart I have a standard definition plasma in the work shop. Not worth anything so I just watch it from time to time in the workshop. I have a 720 that I use for the news in the morning. It is burning quite nicely from the stationary graphics. My 63 is relatively power hungry. I do like the picture and some will argue that, but they have never seen my TV room. One of the chairs is at quite an angle and an LCD looks like crap off angle. An oled would look great but that is an expense I dont need right now. Want to get a 65" 4k oled some day but as long as my 63 plasma keeps going I am keeping it.

@@12voltvids Yes it's a mixed bag here as well, and the new builds are not particularly affordable for young people which is a modern day travesty if you ask me. My parents' home is a semi-detached Edwardian house, pretty typical of the era - large rooms, but not much in the way of garden/ outdoor space. Mine and my brother's house (we're neighbours), are both mid-1930's built, and the exact opposite - smaller rooms, but huge gardens!

I did. They are all tight and they have locktite on the threads. It was the 2012 models that had that problem.

Well there certainly isn't any money in fixing stuff these days. I actually like the older stuff better myself. I like plasma tvs just because the science behind what makes them light up is so complex, it is actually cool. LCD is boring. Plot an X-Y coordinate and apply a voltage to stimulate liquid crystals to change polarity. Yawn. Now plasma you are talking science. Prechare the panel, select the line and apply a firing voltage to create an electric discharge. When you fire that discharge in the timing cycle determines the brightness. Then extinguish and charge to prepare for next sub frame. Do that 600 times a second.

Plasma went out of production because it cost too much to make. Now OLED is the king of picture quality.

Pioneer had the best plasma sets. No question there and the were also the most expensive sets compared to other brands. When they shut down in 2008 Panasonic bought the technology from pioneer, and incorporated it into the high end Panasonic models. I have one and it is beautiful. Power hungry you bet, cooling fans, check. Perfect picture, yup. Perfect blacks, absolutely.

I'm waiting to see how micro led pan out.

Open it up and tighten the board grounding screws before it fails. Once it goes pop you will have a problem.

You poor little thing, having such weak little wrists and hands must be so handicapping. You realise that holding a drill to unscrew results in exactly the same amount of force being transferred to your hand? Then you must add the weight of the drill, which is adding extra work for your arms, wrist and hands!

A drill is overkill. A cordless screwdriver is what I use.

Yes loud and friendly. He stole the show?

@@12voltvids my bad

Same problem. Did you fix it?

It should work for many years.

Yes I have a 50 as well. In my panasonic collection I have a 42SD, a 42 full HD, a 42 THX certified 1080p, this one, and a 2012 50" 1080 set. I also have a 50" panasonic that has a seperate tuner box but that one is not fixed yet. Other plasma sets I have are an 720p 42 LG, 720 50" samsung, and 1080 FHD 63 samsung. I have 3 more samsung plasma sets that have panel problems (vert line or 2 in the screen)

What causes the black vertical bars on the plasma sets?@@12voltvids

@@petenamlook18 I have know idea mines never done that

@@petenamlook18 A back vertical bar approximately 1" wide is usually caused by a connection between one of the FPC tabs and the C board along the bottom. It could be caused by a bad drive IC on the FPC as well which is non repairable. A single vertical line line (black, red, green or blue) is a failure of the drive IC on the FPC that corresponds to that area of the screen, or the panel itself. Single line failure requires replacing of the panel to fix. 1" wide might just need one of the connectors restated. If it is a horizontal line it could be the a connection between one upper or lower buffer and FPC on the left side of the screen looking from the back. Or it could be one of the buffer chips on the buffer board. If it is on the top half it would be the upper board, and lower half the lower board. I have a total of 11 working plasma screens. 2 of them have single vertical line failures which is the panel. They are used for gaming, and an advertising display, and one has a small crack in the glass, but the set still works and I watch that one daily on the news channel so it is getting a real nice permanent burn it from the TV station logos and news ticker. Out of all those TVs I watch 3 regularly. The 2 with bad screens are used for gaming and digital signage, and the rest are sitting at the back of a closet awaiting the day when I need to put one in service when one of the others breaks beyond repair. I got all except the first 2 for free. I have had many more, but I do sell my spares for those people that want a plasma. There are people out there that seek out plasma TVs now that they can't buy them anymore.

I have 4 Panasonic plasmas... 50in.. I wont purchase any other TV but a Panasonic.... Their plasma line are true work horses... I had one 55-inch that stayed on for 3 months straight without being turned off.... The only thing that ever happened to it is the asshole Comcast guy reconnected the television straight into the wall saying that it would be a better picture... 2 days later an electrical storm fried my HDMI 1 and everything that was plugged in there after.... Laptop... Passport external hard drive... And a crappy MP3.... All because of Mr. Xfinity... Of course they would accept no responsibility..

Just ask Louis Rossmann.

@@richardhz-oi8px That's what I was thinking.

Lp was never a recognized speed. Only sp and ep. Lp typically used the narrow ep heads and there are gaps between the tracks. Even a slight alignment error will cause auto tracking to have issues.

12voltvids thanks! Do you think that replacing the AC head solves the problem. The drum is completely cleared. I'll watch a video in your channel about vcr alignment

@@raynegames2636 I have never seen an a/c head fail. If it was bad you would get no playback period.

I have another iron. Just couldn't bother waiting for it to warm up. I have had igbt fail on ss board. Caused by loose ground screws.

@@12voltvids Yes it's strange the screws are always loose. You have a knock off hakko T12 station now right? Those things are up to temp in like 12 seconds. I have two with a bunch of different tips. Love em.

@@jeffescortlx Yes that was a problem. Panasonic came up with a service kit for the 2012 models that included new screws with lock washers. This set the screws are set with loctite, so these ones won't be a coming loose.

Well it happens, and now you know how to troubleshoot it.

You think this throws heat you should try the 63 Samsung I have. It warms the room nicely. How about the monster 104" Panasonic plasma. It draws 20 amps @ 240 volts. About 4500 watts!!!!! This one 350 watts. I have an older 42" sd panel that draws more.

So very true! We are in Central Florida and also had a plasma for a while but had to get rid of it because it just created too much heat 85% of the year. Now, when the seriously cold waves hit and the temperatures plummeted down to around 65-68°f (brrrr), it was fine because we could heat the whole house with it. 😎

Switch to cinema mode, it is more light controlled and uses less power..

@@TheRealJohnHooper Yes I am aware of this. This TV is now one of my spare sets. Has not been used since I fixed it. I now have 3 perfect working Panasonic plasma TVs waiting for one of the others to blow up so i can use them. So I guess you know what yhay means. I will br watching plasma TVs for a long, long time. I have a 42thx certified, 46 and 50 waiting to be used.

If you wait for a failure these tvs last forever on purpose.. Just to annoy you :D

Manual? What manual. Don't have any and have no idea where to get.

Looks the same, just less in it.

331 watts full white screen brightnes set to max. In realith is is more line about 130 to 150 or lower on dark scenes.

@@12voltvids Thank you for the quick reply. What I always wondered is, if you're watching a plasma set as your main TV set, would raise your power bill substantially?

At a rate of 0.12 per KWH running this TV for 3 hours would consume just under 1KWh which would cost .12 so about .04 per hour to operate. Our electricity here is .08 for the first 1360 KWH in billing cycle and then just over .13 for the rest of the billing cycle so no they don't cost that much to operate. All the wall warts, phone chargers, modem, cable boxes and all other electronics in standby 24 hours a day uses more.

@@12voltvids Dave, Thanks a lot for the detailed answer. One thing I've always appreciated is that you've always taken the time to answer my questions completely and thoroughly.

No I do very little. Water change every few months. I have a bucket of fresh water with a pump and float control to top up the water as it evaporates. I fill the bucket about once a week. Feed them every day and check / clean protein skimmer. Once established they are no more work than fresh water other than mixing salt for water change.
