    Thanks for your tips - I have/can use a multi meter, but have never worked on a tv before - is it possible to give some guidance on where to test? (We live remote and it will take some time to access a technician).

    The model number is: TH-42PV30 and serial number: YB4530084. Thanks

Hello stanton01, Sounds like a main circuit may have blown out from your tv, this usually happens because of voltage regulation, meaning that if the voltage is not regulater correctly it might have been affecting your Tv until it eventually burned out the video card. It is not that expensive to fix if you plan to fix it yourself, but if you still have warranty I would rather get a warranty replacement.
good luck!

NO VOLUME bars means your Display panel isn't even PRIMING (that's when the panel "gently lights up" before the video comes online)

That also means that either the X-sus, Y-sus or the Z-sus board isn't powering up the pixels....I doubt the power supply is faulty since you do get sound.

It is better u should take it to service center...

If this was a laptop I would say that the backlight has blown. What is the model number of your tv? and when was it purchased?

The most likely issue is that the Power Supply has burnt out, you were able to let it cool at get it to work for a while, but perhaps part of the board has melted enough to cause a short. Repairs will cost approx. $300-500.

FLASHING POWER RED BUTTON 7 TIMES


I believe that is a bad power supply board. You can unplug set ,open the back access panel and look for swollen electrolytic capacitors they will most likely be slightly rounded on top instead of flat top like the others.Not sure if just replacing caps is enough we mainly swap out whole board.Some models' replacement power supply is slightly different from original in that a couple of the plugs are in different spots and require an extension cable.
