SOURCE: Philips flat screen TV MODEL ID 19PFL5422D/27

I bought the television less than a year ago, so I called Philips Magnavox and they asked for the serial and model numbers. Next thing I know they asked for my name and address and Philips is sending a brand new television to replace it !!! The new one should arrive in about ten days. How's that for service? I'm very happy that I bought Philips and I will do so again. So don't forget to keep all the paper work that comes with your new televisions,especially Model and Serial numbers ! Thanks for asking , Debbie Hoffman

check first the psu unplugging the Y-sus from it if the voltages stay on then you have a Y-sus failure if the psu keeps closing then its most likely the psu itself or your main board

LG TV KEEPS TURNING OFF


Kindly do not keep attempting to turn it on, as you are likely to spoil some other boards/parts/components of the TV. Look for any loose contacts in power out let, RC jack, cable and socket. In order to ensure, it is not caused by the input device, connect a DVD player
and see. Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.

Sounds like it started "Protection Mode" because of a failed electronic part inside the TV. When this happens, the TV will keep turning itself OFF or will not turn ON at all. This keeps the other parts inside from being damaged. Most likely the TV has a power supply related problem. The common part to go bad for flat panel screens circuit board that powers the screen itself. Most manufactures call it a Backlight Inverter Board.
But, I can't say what is 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptom.

You have a few choices:

1. Best thing to do, 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, schematics, test points, and part# lists.Usually, cost under $20. Its the best repair guide material for fixing TVs. And most cases the new part cost less than $15 by searching on the internet with the part number.

2. 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.
