Well this set's or kind of funny, they have issues with eprom and static problem that causes the set to do thing, that narmaly you wouldn't do in a marige life.
I narmaly try by reseting the unit, unplug the unit for about 10 min and try again to see if it reset, if it didn't then I would unplug the set take the back cover off then reset the cpu and the eprom by shorting the pin's on each ic's to ground, and then try again.
If for some reason your set don't work at the end well check all connection again, narmaly I solve 99% of the problem.
If this don't help, when you can replace the cpu and the eprom to solve your problem.

I hope this help,

We have a Phillips plasma tv and the picture pixelates randomly and freezes for about a second and sound breaks also. We have had everything checked and have been unable to find a solution. The latest...


In my openion, Its problem of hardware in your TV and signal processing circuits are involved. It might be problem of Firmware (programe to control the performence over all) Philips can advise you better in this regard.

litigation- O.k if your tv is cycling through the menu ect. it sounds like you have a bad tact switch.Try pressing the contol panel buttons repeatedly,most of the time the remote is used so the tact switches go bad. Try this out ,it may help to clean the contacts. Just make sure you press them alot,it helps most of the time,if not you may wind up in the repair shop.Have fun and let me know. cooltek Mar,4/08
