There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

LCD TV backlight goes off but still sound is present. Sometime it happen within few minutes and sometime take 30 minutes plus. Is that inverter Problem or CCFL? how I can rectify?


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I HAVE OLD PHILIPS MODEL:21PT128A-71R THE DAMAGE IS NO POWER WHAT ARE THE POSIBLE DAMAGE?


Most likely the TV has a power supply related problem. The most common thing to go out is the circuitboard that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.

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 flashing codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

Red light on my Philips tv goes 7 times


It's basically a common problem with all brands of flat panel TVs. Heat is the biggest enemy for circuit boards. And the flat panel TV generates a lot of heat.
The most common part to fail is the power supply board (Backlight Inverter Board) for the screen or the Main Power Supply Board for the TV itself. The flashing 7 times is a code for a technician look at a certain circuit path for the malfunction.
If you have some electronic experience and you want to repair it yourself, you can sometimes find a Service Manual over the internet for less than $20. It will have red light flashing codes, diagrams, schematics, and part number list. Cheaper than buying a new TV. :)

Screen is dimmed and flashing


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.

Stand by light flashes red on powering up with remote and the green light flashes approx 15 or times before the screen illuminates.


thats pretty normal, it takes a good second or two to warm up and the display to turn on(at least0, you get the green flashes as you hold for on, 1 sec is a long time at times, lol, be patient, no problem with your tv!
