Having the same issues on my e70 e3 how did you find the board. Would it be the tcon?

Where did you purchase the part from

@@MsLyssie07 eBay with a 100% return policy

yes where did you order your part(s) from ?

Thanks for watching-hope it helped!

Hope it works out! Def worth a shot

Right on! Thanks

TO move the LED's around you have to take the bezel and screen off which is about 10 times as much work as removing just the rear cover of the TV. Testing the driver board outputs to the LED with a multi-meter to confirm no voltage output to the LEDs would be the best way.

@@RPG-oh1yf I don't mean physically move the LEDs. Move the connections to the LEDs from one port on the driver board to another. I did that on one I'm fixing. And it showed the driver board is likely fine, it's the LEDs (which sucks because now I have to take the panel apart and replace a bunch of LEDs). And indeed, tests on the LED strips showed bad LEDs, confirming the earlier diagnostic.

@@ccoder4953 Ok, sorry for the misunderstanding. On my 65" vizio I'm trouble shooting there's only 2 harnesses that power the 12 LED strips and all of them are out and all went out within a month, little by little. I'm leaning driver board. Missing the power cable or I'd test them now. What I don't get is how do all the LED's fail at once in your case of it's NOT the driver board? Maybe the board also failed and overpowered them all and cooked them?

@@RPG-oh1yf Oh, that's easy. LEDs are often wired in series (like old Christmas lights). A common failure mode is for them to go open circuit. So, if one LED opens up, the whole string goes out. I had a panel do that once. Turned out it was just a few bad LEDs. It's also possible you have some LEDs in series and some in parallel. If you have some die (shorted or open can do it), it can cause more current to flow into the other parallel branches, stressing those LEDs more. See, LED drivers regulate current, not voltage. But unless it's pretty sophisticated (and it sounds like yours is not), they can only regulate the current of an entire series/parallel string. So, if one parallel string isn't doing the current it should, the other branches will have to do more. But that stresses those harder, so they are more likely to fail. What's weird is the new one I'm working on (with full array dimming, so much more complicated) has LEDs in series, but somehow bad LEDs aren't taking out a whole series string. Might be because the newer panel has 9V LEDs (I think) and the old one had more normal 3V LEDs. The 9V LEDs are internally quite a bit different - internally, they are several LEDs in series, where the 3V ones are just one. So, maybe they are more likely to fail shorted.

@@ccoder4953 Interesting. Seems mine failed in 3 segments. First I lost about 1/4 of the backlight, then 3 weeks later we lost about another 1/2 of it and finally the last 1/4 went out. Seems like that should be LED drive board based on that 3 stage failure but hard to say. I am probably going to order a new board from Ebay, can't beat $5 shipped for a new salvaged board I need. IF that doesn't work I can pull the panel apart and check the LED strips.

Wow, that is bizarre. Glad everything eventually started working for you.

Worth a shot! Best of luck

Right on! Yes, I would try the board first before the strips - especially if it's occasionally lighting up. Usually an LED either works, or it doesn't - which leads me to also think power supply / driver board. Good luck!

I'm having the same issue with the same TV. My lights went out one by one to the point my whole screen is dark now. I've only had the TV for 9 months.

Oh geez... our 75" same! 🤦🏼‍♀️ First bottom, then right side and quickly entire screen black. We have taken the back off to try to find a replacement board in hopes it works. At least we've had ours for two years.

@@SheilaSmithPaparazzidid it work?

Yeah, I'm not sure. I didn't examine them or try to figure that out when I tore mine apart. Good luck!

Seems to be a somewhat common problem. When I did mine, the video board was about $20 - might be worth trying.

I'm not a pro at any of this. The only way to know for sure is by checking the video board and LEDs with a multi-meter. Good luck!

I'm not an expert, but yes-that sounds like a bad LED strip.

I'm not sure. I'm not a pro at this stuff, just a dude who tinkers. Maybe check forums.

@@swhammondbuildsreviews ok, thanks for responding back to my question.

Sounds like a reasonable assumption. The only way to know for sure is by testing them with a multi-meter. Thanks for watching!

I agree-the only way to know for sure if by chasing possible issues with a multi-meter. And yes, the battery trick works for checking LEDs, haha.

Sounds like a bad LED strip if it's a uniform outage across the screen. Good luck!

Could be a power supply issue. Maybe get the voltmeter out and try to chase it down?

Yes, Kyle-I think you're correct. I should have checked the capacitors, my gut tells me this was probably the issue. Anyone reading this in the future, use a multi-meter to test the capacitors on the driver board - it may be an even cheaper fix.

@@swhammondbuildsreviews Just remember that to get a true reading from these caps, they need to be carefully de-soldered from the board.

Did that fix your tv, I have the same problem

No, I believe the main board is usually different from the video board.

Not sure?? I'm not a pro at this, just a guy who tinkers. Search the forums or Reddit.

Sounds like you have LED light strips that have gone out. If it were the video board, it would be entire sections.

¯\_(ツ)_/¯ I'm just a dude who tinkers

Impossible to know for sure-you'll have to take a multi-meter to test the board and LED strips. If the board isn't providing current to the LED strips, it's likely a bad board / transistor. If the board is providing current, it's likely bad LED strips. You can gamble and cheaply / easily replace the board if you feel that you have a uniform outage like what is happening in this video. Replacing LED strips is more involved.

Bummah!

Hey, Frank-I hope it's a simple fix. You're right, my guess is that the new LED board will fix the square, but it sounds like you might have a strip out as well. I would certainly try replacing the board first and hope that fixes everything. Best of luck and let me know how it turns out!

Same model tv here....ordered a new/used led driver board...hopefully it works...

@@joeparent8760 did it work ?

@@joeparent8760 did it work?

I am not a pro at this stuff - the only tv I've ever fixed is the one you see in this video. But yes, given what you've told me, it sounds more like a driver board issue - or even a motherboard issue - rather than an LED issue. Sorry I'm not better help!

I'd assume they're pretty similar. LED TVs and LED monitors are basically the same thing - monitors usually have a little more robust hardware and faster refresh rates. It's worth trying, but I can't promise anything as I don't know anything about your particular monitor.

It sounds like you have it narrowed down to the two likely culprits. The only way to know for sure is to tear it down and check both the LED strips and video board with a multi-meter. With the lights coming back on after power cycling, it makes me think that LEDs aren't burned out - it sounds more like a video board issue - but that's just a guess. Good luck!

If it's a uniform outage as you describe-it makes me think it's the video board. The only way to know for sure is by taking it all apart and testing the LED strips...

I'm not sure. My TV had a specific video driver board.

¯\_(ツ)_/¯ - I'm just a dude who tinkers. Could be a power supply issue to the quadrants? Hope you figure it out though. Terrible about the Vizio tech!!!

My vizio 75in has a similar issue. Top right and it looks smaller dark spot. Half the size of the on in this video. Almost like a shadow burn in.. did you ever find a fix?

The only way to know for sure is by testing the board with a multi-meter.

¯\_(ツ)_/¯ I'm just a dude who tinkers. I assume you could test the power output / continuity of the video board with a multi-meter

For now disabling Active Full Array resolves the issue regarding of the Picture mode. I am going to guess this has something to do with the different model # board not completely matching the rest of the system/panel.

I would assume it's the different model board as well. Glad you figured out a workaround with disabling active full array.

Sounds logical. I'm not a pro at this stuff, just a guy trying to fix my broken crap.

Is that the only way to test the board? It sounds simplest so just asking.

I have no way of knowing-I'm not a pro at this. Your guess is as good as mine. The only way to know for sure is to tear it down and test everything with a volt meter. Wish I was better help!

Hmm - my assumption is either the board works, or it doesn't. The "starting to go dark" concerns me. I don't think that as a quadrant fails, it's a slow process where things begin to dim. I'm guessing it's an all or nothing situation. The only way to know for sure if checking the video board with a multi-meter. If the fading quadrant is getting proper voltage, my next guess would be failing LEDs or a power supply issue. Hope that helps!

Did this work? I have the same model

I ended up just buying the LED lights and that did the trick, I did not buy the board.

Thanks for watching. Could be a power supply or video board issue. It doesn't sound like it's the LEDs the way you describe-too weird for all of your strips to "burn" out all together like that. I would try swapping the video board first, it's cheap and easy, and go from there. You could away get a multimeter out and try to chase down the problem that way. Again, I'm not a pro at this stuff-just some dude that needed to fix their TV!

@@swhammondbuildsreviews Thanks for getting back, is there way for me to show u my issue by sending photo? Tv itself 3 years old initially it started by becoming 1 strip going dark then turning whole block. So right now it is upper right, lower left both are whole block and since last texting you I ve got upper left only 1 strip dark, do u still think it is not led strip issue and where to get part? I wish I could chase the issue by checking but Im not an electrician so I kind of rely on your experts, thanks.

@@fi4007 I'm really not an expert at this. There's no way I could tell you what was wrong by looking at a photo. I did mine wrong the first time, thinking it was an LED strip problem. After replacing all of the LEDs, I discovered that it was a video board issue. That's why I made the video, to save people the hassle of replacing LED strips. It sounds like you may have several issues going on? My advice is to read forums and watch more KZfaq videos with similar problems to yours. In the description I put a link to the part store where I bought my video board. Of course, your part will be different depending on your model. Good luck!

@@swhammondbuildsreviews Thanks for your response.

The only way to know for sure is by testing the LED strips and video board with a multi-meter, and possibly back to the power supply. If your LED lights came back on at all after replacing the video board, it doesn't sound like the LED strips are broken. Possibly something is overloading the video board and keeps frying it. Just guesses, I'm not a pro at this stuff. Possibly consider replacing capacitors rather than the entire video board.

not sure if you have solved your issue or not but I picked up a E60-E3 and the entire screen was dim. after disassembling it I noticed the connector for the backlight was a little burnt. If I wiggled this connection the entire screen lights up. if I wiggle it a little more the top row goes dim. Wiggling it once again and it works properly. I took a toothbrush and some rubbing alcohol to clean the connectors and now it is working 99% of the time. It occasionally will dim but comes right back!

@@ChadMees I did, it was the LED strips. I found a set on ebay and replaced all of them. Works great (for now)! Thanks

I'm not a "tech support" guy - even if I saw the pic, I'd have no idea what I'm looking at. I just tinker, try to fix things when they break, and post an occasional video when I think others will find it helpful. My best is advice is to hit up the forums. Good luck!

🤷‍♂️

Maybe a bad capacitor or transistor that powers that led strip? Or a bad connection somewhere. Something can't sustain the power flow. You could try baking your boards to see if it fixes the problem, maybe a bad solder joint somewhere.

I have the same issue

Sounds like it. The only way to know for sure is to use a multi-meter and check voltage coming out of the video board. If the output is normal and the LED aren't lighting up, you have LED strip issue. If voltage isn't correct coming out of the video board, you have a video board issue.

Is the juice worth the squeeze... it's an age old question.

I taped together some 9V batteries and wire and touched the LED leads to test the lights. There's actual products you can buy to do this, or search KZfaq for this ghetto trick.

A different issue, but could still be the video board. ¯\_(ツ)_/¯ I'm just a dude who tinkers

I highly recommend the 12 gauge, haha

@@swhammondbuildsreviews well bought a hi sense tv from someone KZfaq videos keeps sticking that one might be next to feel the gauge

A broken TV? Haha

Smart. Problem. Gonna take it apart today

@@swhammondbuildsreviews lol Thanks for info, man.

Possibly-what you describe sounds like a video board issue and not an LED strip issue.

Any way in particular that you would recommend testing this? The picture isn't messed up or absent, its just the dim spots in the corners and a bit of light flicker.

@@hbtdawgz1688 it can be a pain, but you'll have to tear the TV down and expose the LED strips. Test the LED strips individually, you can use the battery trick (kzfaq.info/get/bejne/atZ7adJjqbOwh4U.html). If all the strips are lighting up using the tester, your LED strips are working properly and it's a driver board / power supply issue. If the LED strips are not working properly, you would then need to replace the LED strips. Good luck!

@@swhammondbuildsreviews Well I didn't have any of those batteries on hand but I did have a 6V battery pack and I applied it to each light. Definitely have some out. Only had maybe 4 strips where there wasn't at least one light out. Thanks for the advice.

@@hbtdawgz1688 Well, the good news is that you were able to chase down the problem! You've already done the hard part-swapping out the LED strips is pretty easy. Glad you're figuring it out and getting it fixed.

Haha, much easier than what I did!

Check this description - there's a link. Be sure to verify your make and model, the link is for the model of my TV. Good luck!

@@swhammondbuildsreviews Thank you! I did that! Just ordered mine. Should be here in one week. Cant wait to get this done I have now four of these quadrants out! Looking forward to fixing this! I cant thank you enough!

Bummer. Only way to know where the problem is for sure is by checking LED's and driver board with a multi-meter.
