It can be that it has unstable power supply or the CPU/EPROM are getting scrambled by the noise and spike in the AC line, you may try better AC line conditioner to see if it will help.

Sharp flat tv lc-32sb24u no audio was watching tv last night and the sound just stopped in the middle of a show. picture is perfect. is it worth to fix.


Sir try to check the cables connection at the back of your tv. and if you are using a digital receiver, try to use a dvd to check if there is a sound. If there is a sound the problem is the digital receiver, feel free to send feed back good day and best regards.

42 inch LG Plasma TV - Lost picture


Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

TV Flat Screen does not come on.


It can be fixed. I had this problem almost a year ago. I did an extensive search online and found a solution. Apparently there's a couple of caps that need to be replaced. The tv is manufactured in Southeast Asia where they use cheap parts. They know the tv will go bad in about a year or so but i'm sure they could care less.

I went to Radio Shack and purschased two caps and a soldering kit for $13. That's all it took to fix it. Keep trying to find it on the web again with no luck. It had step by step instructions. If you just unscrew the back you'll be able to find the bad caps, desolder, and replace with the new caps.
