Question about Samsung SPN4235 42 in. Plasma HDTV
50"samsung plasma less than 2 years old ,screen turned black while watching it one night,sound remains but no picture
Most likely the TV has a power supply related problem. The most common problem are the power supply for the screen itself. Most manufactures call it a Backlight Inverter Board. Something you may want to look at for your problem. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.
You have a few choices:
1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
