1. check the batteries in your remote. if the batteries need replacement replace them 2. Then click the exit button on the remote. I am not sure of the model of you TV but your user manual should instruct on how to remove the menu screen this is possible that the TV needs a reset. 3. You can unplug the set for 30 second and this usually will solve this issue if not then there is a firmware issue or circuit issue. Hope this helps you with your issue. Have a great day!
I had an LG 37" LCD that did this to me. Turned out to be bad solder joints on the side button board. Just reflowed and it starting working fine.
But now that I think about, I had another set do the same thing, only it wasn't the button board. I had to upgrade the TV's firmware via the USB service port. Just needed a USB flash drive and downloaded the firmware from the mfg's website. There were easy to follow instructions there too!
If the menu display isn't coming up either, then the odds are the power supply for the screen is the problem. Most manufactures call this a Backlight Inverter Board. Being that it's only 7 month old, it should still be under warranty by the manufacture. I would try to get it fixed by the warranty first if possible.
It could be dirt/dust has accumulated behind the buttons causing a false contact so it looks like a ghost is operating your tv making things appear and disappear.If this isn not the problem then there is a faulty component on the board where the buttons are located. If you are able to do the cleaning of the buttons yourself use a cleaner that de-greases as wel and make sure everything is bone dry before re-assembly. If not find a competant technician. Hope this helps.
I hate to call Philips liars but the logic of the situation speaks for itself. If it was a software fault then your tv would have done this from day one and I bet it just started to do it out of the blue. I think it could be a faulty component on the board where the buttons are located. Hope this helps.
Sounds like a main board or a sustain board problem. This is most definantly not a repair job for the consumer to attempt. Please call in someone who is experienced with Plasma TV sets, as these boards can be very very expensive. Too expensive for you to guess and buy and then have to order the other one. Oh this model also has some power supply issues as well. Good Luck
