Question about Philips 60PP9202 60" Rear Projection HDTV-Ready Television
I just replaced the two IC (STK392-120) and 4 resistors that tested open.
Now the unit will power up, in that the red power light will come on and remain steady, but there is no picture or sound.
When I use the remote the power light will blink, but I cannot get the menu to show up.
I checked two fuses labeled 1000 and 1300. Both checked good.
This is a mayor job,
check the screen voltage, the filaments to the crt, the high voltage at least on 1 crt

Its possible that the opto ic went south at the same time you had the convergence problems. This is fairly common for these sets. Check to see if they have a chip kit on www.magnavaoxhelp.com for your model.

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,
