I first started with a red screen I changed the power supply because the caps were bulging. I next changed the upper and lower buffer board which the tv worked for about an 1 1/2 hour then the y sus board started to click and I changed the ipms on the board I put in two sanyo ipms put the board in and the tv works. Now I am getting when the tv sits for about 12 hours i can turn on the tv and I will get a picture but no sound i can turn up the volume and nothing. But when I go into the menu under audio and flip the check mark from front speaker on to off and then back to on again the sound comes back on to the front speakers I can shut the tv off and come back 4 hours later and the sound will be there but after 12 or more hours not. I am asking what could be wrong or doing this I greatly appreciate the help. Thank you Ron

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't

All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

Hello, I bought this Mac from a friend, he said that it simply stop working. The MacBook looks very clean but does not power on, stuck on 5v 0.42A, and sometimes display 5V and 0A (then 0.071A and again 0A).
I opened it looking for some problem, it was not touched before for sure and the board is very clena, no spot of corrosion at all from what I can see. Voltage on multimeter of the board off the case it's the same, 5V 0.42A. But then I noticed this "clicking sound" come from the board ( I attached here the audio file).
Looking on google I found this:... -
Hi I am new to this kind of repairs but I want to learn..I have a Samsung UN65JS8500F. the TV used to work and I tried to fix darker areas in the middle only ( img 1,2,3).

Now the tv shows no welcome screen and no sound is available thru the speakers. ..just a black screen..Backlight LED do turn on...also noticed a 5 blink code , not sure if that was there before. I can...
