This is getting confusing. There are many videos out there that say to isolate the oscilloscope and now this video says not to do that. Sounds like two different doctors prescribing different meds for the same condition. it sounds like you can blow up your scope no matter what step you take.

I Have. A 1999 MTX AUDIO THUNDER 204 4CH VOICE AMP... I HAD IT PUSSHING 8 PIONEER VIICE SPEAKERS. UNTIL BEER GOT INTO IT.. I HAVE PICTURES OF WHATS WRONG WITH IT. LET ME KNOW You want to look at it

GOD bless this man! I Straightened my PINS using a needle. Love you bro you saved my money ❤.

Just bought a Hitachi SR-703 in a local auction. Only bid offerred USD 35. Delivery +USD 20. Fully functioning save for some incandescent bulbs.

That's the problem with electronics you have to spend a fortune on gear!

Oh ok 10 Hours wow

How long did the job take all altogether?

I have Toyota head unit which stuck in boot loop. There is no obvious burning sign or default parts. How to test IC like yours with multimeter? There is no label on the IC.

Can I run a ground rod separate from my house ground connection and be completely isolated from my home wall supply?

It to bad you don't show examples of what you're talking about. Otherwise, you post would be better for most people listening to what you're talking about.

Spent another 20 minutes on it. My theory about channel select was right. Now weirdly I am getting Audio output to the TV, either directly hooked or up scaled to the USB/HDMI device. I am going to purchase a new video cable tomorrow as I have no continuity testing (multi meter). I have over 30 to 40 years of cables. So always amuses me, when I can't find one to use, easily. :) 'Murphies Law - How I got so good at fixing everything :). TV, is syncing correctly and is reporting it as 720P (NTSC resolution), but then fails to produce and output from there (A bit weird that?).

Hi, I have come into possession of an (NTSC), Phillips VR255/75. As per usual second hand, no remote. I have only managed to find a 'Spec', sheet for it. But I was hoping there was away using the buttons on the device to force it to the 'AV', channel? It stops at one counting down, using the channel buttons. I suppose I better force it to count up to what I assume will be 99. It is not outputting off the leads to my modern TV. Funny as I can actually directly plug a PS2 in without having to use and Upscaler to HDMI. In between. Both Devices I have are showing as NTSC. We are on 50HZ, mains here in New Zealand and use the lower density Pal Standards for all our old broadcasts, prior to digital. I am kind of hoping my T.V. is clever enough to re-sync. The Upscaler is showing a display, so this sort of suggest that the T.V. is agnostic to Pal/NTSC conversion. Anyway upshot at moment now output, no remote. Thanks if you can help me. I used to do some of this work too. We used to buy in the rubber drive belts from another supplier. Used in so many mechanical devices right through. :)

You seem to know your stuff on these volume pots, my question I am not a tech and need someone to rebuild my volume pot on my Pioneer sx1250 which is not not working now. If I send it to you will you try and rebuild it. I can pay for the repair. Please let me know.

Glad to see you working on Alpine Gear, doesn't lend itself much confidence in the Brand though burning up like that and poor QC looking at loose transistor controllers, or you think that was just normal wear and tear?

lmao! i just got one 2024 and it looks like yar wang calibrated mine too 😅

You still fixing these?

Makes me grateful my 96 Z28 has crank windows 😎

Hi bro what about CD RECEIVER CDE-133EBT

This help me a lot Thank u So much !!!!!!!!!!!!!!!

Get a headlamp, they’re like $15 Terrible camera work

have a onkyo nr 757 has a blown side what is blown it happened when it was on and I touched the the speaker wire on the back of amp then smoke cake out of it

Soundbars are poorly made, they don't last. A good component 2 channel stereo will long outlast a television.

I have a TX606 that has this issue. Would really like it up and running as it was the secondary reciever for my gaming setup. Would you be able to fix it

I wish

Where you located

Do you know which head unit is compatible with Alpine CDA 117? Mine was removed and only works on RCA.

Hello. I am looking for a service manual for the Klipsch SW 112 subwoofer. Best Regards SK

super video

I have the alpine 175BT hesdunit there is nobody in my area that will work on it the audio shop hooked it up and it keeps blowing fuse for thr remote wire

Hi , would you please share a video of how you assemble its gearbox ?

I was contemplating this when I stumbled onto your video. I use my 123 on digital pinball MPU's and sound boards and have for years. I actually have two 123's. One here at home and one in my toolbox at the shop. I was tired of using it plugged into the charger. The original pack batteries had crimp tabs and the new ones do not, (as I suspect Fluke got them custom made), I had a few issues putting fresh solder onto the exposed surfaces maybe due to my fear of using too much heat but with some good flux was able to get enough for wire attachment. So, after assembling the pack it started charging the batteries at 5.6VDC. It went up to 5.8VDC at the end. I left it for 12 hours while monitoring the voltage with one of those cheap Chinese 3 digit meters. After disconnecting the charger it showed 5.1VDC across the battery pack. The scope turned on right away and looks good. It is now under the battery refresh mode. Next week I will tackle the other one. Thanks for the video!

Is there a test/health check for pins I can run after the fix?

Hello, is this instrument used only for discharging process or can it be used also for charging process?

Sweet compound? What's the name of the stuff you put between that one part and the other part? The white plastic tube with white goo? I wish you were my neighbor. I shorted one of my only two out of five. You'd be my favorite neighbor. I loath circuitry lol

Hey how are u doing i have an alpine mrv 1507 i would like u to repair it is very sentimental to me ive had it for 30 years ive watch ur page and i like ur work how could i getvin contact with u

I am happy to see how you fixed it. Have an option of purchasing one of these. The seller does not show it turned on. Maybe it has the same issue. Now I know how to fix it. Thank you for showing how to fix it. That totally worked after you cleaned the pins. Very cool!

Good Job👍💯

I have to do this, not looking forward to it.

How do I go about having you fix my amp

A Very good repair

Never remove the ground from your test equipment. Isolate you equipment that your testing. Also use a current limit high wattage light bulb in AC circuit. Use caution Always!!

Awesome lab! Here is a tour of my nerd lab: kzfaq.info/get/bejne/fcB_iZZl28jXiqc.html

I'm confused , we see the characteristics of battery 7.2 AH that means per hour 7.2 Amp gives while other place in its table we see for one hour the battery give us 4.3 Amp, why these aren't the same ???

hey man i have a question by any chance are fixing any stereos sent by subscribers? i have a pioneer deh p9200r that i really want to fix, ive looking everywhere but i had no luck so i came across this channel and i wanted to ask. Please get back to me i would appreciate it

very good..Thank Mr

mine wasn't the same model number but looked exactly like this one. Mine would only work when it was tipped to the right side. Wouldn't work holding it straight up or tipped to the left. I finally figured it out. I took battery out and bent the two contact points in just a little. Works fine now.

It might not work after time slamming the lid down ? Prob help squeezing the lid trigger before opening & closing it ! Their not the best design ! I've had 2 envoys & both the rubber post were broken , people try to get in them too fast & when they open the lid they open it before the rubber post clears the console , they pull the top lid back & snaps the rubber post !! Amazon has them now 19 bucks than delivery charges on top of that !

Nice video love the setup thanks for the info like you said they have the parts but they rather you spend more money 💰 rather then repairing your own times have changed for the worst when buy appliances 😡

This ST 1500W powering my guitar amp. DVM Continuity test shows mains neutral across all recepticals, that have no ground so it's ground isolated; but neutral not so much. Is that any good for an isolation transformer or should I open and remove the neutral cross comnects to all ouyputs?
