    I have had my power supply board replace about a year ago.

    Now I also have the relay click.

    I tried a heater behind the tv and after a while (and many pushes of the power button) I got the screen to light up a few seconds before the relay clicked back off.

    I got the tv to stay on only twice, but now it just clicks right back off.

    Phillips service is no help.

    I paid $500 to fix it once. It is almost cheaper to buy a new tv. (not Pillips)

Ok. I got my tv back on.
I pulled off the back cover and found the relay that was clicking.
I have two blue relays next to each other that click when the power is pushed.
I placed a hair dryer over the relays for about a minute.
Once heated up, it only took 4 tries to get the TV to stay on.

Power supply, check for back caps, remove backing and check for bad bugling caps, if you know how to solder then its might be a fun project to do, if not time for a repairman call or take it to a shop!
