Check for shorts, blown fuses on ysus, if blown replace entire board, easier than locating many of the parts installed on the board.

Philips 50'' Plasma TV model 50pfp5332D/37 GREEN BLINKING ON LOGIC BOARD

Main digital processor IC on the board has damaged. It is not a replaceable part, as normal soldering techniques cannot be applied to de-solder it out from the board, or to solder a new one in place. Card base replacement should be done.

The TV is forced in standby because an internal fault has been detected. 6 blinks slow and three fast blinks points at defective Ysus board or defective buffer. The power supply must also be tested. Till now the TV was starting because when you disconnect power you discharge internal components. Some of the components have the role of storing charge (the capacitors). If a capacitor is defective the TV may still work as other components will compensate the function of the faulty part. After a while more components will fail and the TV will not start anymore. To fix the problem the TV must be tested at component level. Testing will start from PSU voltages to YSus and buffer boards.

Philips 42PF9630A/32 Plasma TV RED led blinking 7 times

Are there any blown caps on the PSB-power supply board. Most sets have sammy boards and they used very shotty caps. If there are no visual clues being a poped cap at the top (X) they simply often do vaporize and dry out. The YSUS-Main and the 2 Y buffer boards control the picture OSD-on screen display. Your not getting any of that. So power supply is where you start first. The YBU-upper and the YBL-lower control the upper and lower OSD the Ysus main control both of them. Usually if you have one in the door you have to replace all 3. But not always. If you were to replace any of the boards I would replace the YSUS-Main, or get the board reworked at a pc repair shop that does board level test and repai. Its more cost effective.

Philips 50 Inch Plasma Model 50PF7320A/37 will not turn on

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.
