I have Philips 49PUS7909 LED smart TV and when i start, only PHILIPS logo is displaying on it. Nothing happens next. Please help.
I did the software-thing aswell, to me it did not work but..
When you remove the backside of the TV, you will find a PCB/board with the powersupply and a PCB with the CPU.remember to remove the interface cable for the ambilight, before you remove the backside of the tv. you gain access to it by removing the shield around the joystik at the down right corner of the backside of the screen
When you have removed the backside of the tv, remove the board with the CPU, remember to remove interface cables so you can turn the board around and look at the backside.
When you look at the backside, you will find 3 massive thermalpads, they might be stucked on the panels backside.
Thermalpads are made by silicone, among others, those pads, might be "sweathing" silicone(or whatever), during long periods of heeattransfer, so take a piece of toiletpaper, and gently remove the sweath/moist from the pad and the board.
Dry the board with a hairdryer after you remove the moist on it and assemble the tv. dont forget the ambilight :)
Let me know how it works.
