Question about Televison & Video
Tv was working fine, unpluged cable from back with tv left on and then unpluged tv. When I went to turn tv back on it clicks on and back off. It seems to cycle approx. every ten seconds if you hold the putton in to power on and power off. It also tries to power up on any of the keys ( menu, volume, channel keys)
I have unpluged tv and waited and tried to power it up with no luck.
my tv was fine, turned it off, won't turn on at all. unplugging, waiting the time then plugging in again, doesn't make any difference. is there a button or something?

This is a common problem on these plasma TV's. The problemresides in the high voltage boards known as the X and Y Sustainboards.. You can purchase them here for a very reasonable price:
The above link is to a Y-SUS board. The X-Sus board is often the 2nd cause of failure and can be found here:
Totest which board is failing, you need to check voltage input to theYSUS board first... Input should be 120V from Power supply, outputshould be above 250V.. Do this test with XSUS disconnected. IF 250+Vexists, then XSUS is damaged. If not, then the YSUS is the faulty part.

You may need to replace the Y-buffer to say the least. And if this is not the problem, you will need to replace theY-main board. If the Y-main board is bad you will also change the Y-buffer. Please see a Philips Tech!!!

The tv needs the power supply serviced, most likely ( 2) 3300u 10v capacitors. (they can be spotted because they will bulge on top) best to have a pro replace them, however since I am telling you what the problem is try to negotiate a fair price - no more than $150 dollars. you can try to do it yourself but you will need soldering equipment and some level of electronics knowledge. good luck.
