IF YOU ONLY CHANGED THE BUFFER, YOU SHOULD CHANGE THE Y-MAIN ALSO, THAT BUFFER TAKES OUT THE Y-MAIN AND VISA-VERSA

I turn my tv on the picture and sound all work and after about 20min the picture goes to a black screen and I still have my sound. I turned the tv off wait about 5 min turn it back on the picture come on...


If you have electronics experience - check the power supply and make sure you are getting the correct voltage to your inverter boards and main av board - also do you see any movement on the screen take a flashlight and shine on the screen - if you can see a dark image on the screen check inverter boards and power first.

thanks,

michael

My Sylvania flat screen sound keeps going off


Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts. Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts. http://electronicshelponline.blogspot.com/ The most probable cause is with its audio output IC itself; overheats.

Sounds like bad capacitors on the power supply board. Locate power supply board, remove it carefully and check capacitors on an esr meter.

Blank screen on my cell, Help!!!!!!!


If both screens are blank: Check the ribbon cable running from the bottom of the phone to the top, apperantly this is a common problem with these. You will need a t6 screwdriver. Part is about 8 bucks on e-bay.

Sounds like a thermal breakdown of a componet. it could be in the main power supply regulaor supply or even a bad capacitor in the power or sweep supply. In some cases Zener diodes can break down and change values after warm up. In some cases also bad solder connections in the highvoltage section, or the power supply can cause this problem. It is a hard call without being able to look at the set. Just a few leads on where to go first. most likly a combo unit, such as this one , would cost you more then a new one these days. Good Luck PS Please dont forget to rate this thread.
