Question about Philips 50PFP5332D 50 in. Plasma Television
Either the power supply has an issue , or you have a bad buffer board and Ysus scan board or both.red light indicating may mean power supply , 7 blinks the buffers and y board.
It could be just a few bad capacitors on the Power Supply, there could be a bad capacitor on the Y board if its bad it needs to be replaced with the buffers together
If you want to attempt the repair yourself you can do a visual of the power board caps will appear swollen on top.
The ones you are looking for are located almost center bottom of the power board,Usually I can see them clearly with the back on simply shining a light into the back through the holes
With the back removed you will see a few circuit boards the upper one (ac cord runs to it through a small board) is the power supply, it has a lot of capacitors on it (cylindrical standing straight up soldered in and marked on the sides with the positive/negative sides and uf and Volts values)
Philips uses 2200uf or 3300uf at 35Volts rating capacitors, they cost about $1-$2 each
The power board and back unscrew with a torx bit and screwdriver size 10 and 15 , if you do not know how to desolder and resolder then do not attempt this as you may damage the TV more than fix it.
We do not recommend do it yourself, but depending on your knowledge and technical ability you may be able to.
You can replace the whole power supply, .
If there is a blinking red light on the TV count the blinks,if it still blinks after replacing the swollen cap this would indicate a bad buffer board ,
check the capacitors by looking for the swollen tops .
I hope that will helpout.....
