TV Repair Questions? Ask a TV Technician for Answers ASAP
I have a Samsung 1080p 46-in LCD TV. The TV always turns on without a problem, but sometimes after 30 seconds and sometimes after two hours, the screen goes black. There is still audio, and you can still change the channel, but there is no picture. Given the rather well-known capacitor issue on Samsung TVs (albeit for a different failure mode), I removed the back cover, found an electrolytic capacitor that was indeed damaged, replaced it, but still had the issue with the screen going black. If anyone is familiar with this issue and can offer some technical advice, it would be greatly appreciated!---Another note - when the screen goes "black" you can just BARELY make out that the image is still on the screen, but it's black on black.
I had one with a cold solder joint a few months ago.
