Question about Philips Televison & Video
Its a 47'' philips lcd flat panel and it works ocassionally for long periods of time with just the left side dimmed slightly. Then on most ocassions it goes dim through out the tv and flashes or, just doesnt have a picture at all i've been told it's a power board issue? Any other idea's?
It's the #1 plaguing issue with flat panel TVs in all brands.
If the red light on the TV is blinking when this happens, It should be an error trouble code.
The most common thing to go out on flat panel TVs is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. The Backlight Board supplies power to the screen in different sections. With a 47" screen, it maybe divided into 10 to 12 sections. 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 minutes so the TV can 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 red light blinking codes, 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.
I hope I shed some light on the subject for you.
