In your set you have three circuit boards. 

The one on the far left is the SSB, middle board is the LSB, and the board on the right is the power supply board. 

Try yanking cable 1516 that connects the SSB to the LSB. Its a small white ribbon cable. 

Does the set turn on now? 

If so your convergence chips are shot and need to be repalced. You can get a replacement kit and instructions from www.TvRepairKits.com.  If the set tubes still don't light up after yanking 1516 the problem is elsewhere. Most likely the HVG.

Philips 50PP9202 50 in. Rear Projection HDTV-Ready Television?


Hello Anthony14,

 

This is an indication the the red convergence amplifier has goone bad you will need to replace the convergence correction modules. Now before replacing these you may want to make sure that the bias resistors and the zener diodes are ok. The convergence ICs are part number STK329-110 or STK329-150.

 

I would suggest that you get a schematic and equipment to make the needed tests, or take the set to a shop to replace the bad components.

 

I hope this helps,

 

Thank you,
