Question about Philips 55PW9363 55" Rear Projection HDTV-Ready Television

1 Answer

No Picture I notice that a similar problem has been posted by others, I just don't understand televisions so I am posting this. Recently our television has no picture, and no front display button lights. There seems to be a high pitch sound eminating from the television. The sound (thus far) is clear. Can someone suggest what may be the problem and how to repair if possible. Thank you.

Re: No Picture

Hi! Guy,
This sounds like a defective large signal board. This set should be serviced by a qualified
service tech.

Warped Picture & color alignment

This is a convergence problem. I had a similar set recently that was fixed by resoldering poor connections at the flyback transformer and replacing a blown pico fuse located there as well. I will look up my records to get the specific fuse location and post later.

TV Powers on and then shuts down and attempts to start again

Remove all connections from the tv other than rf cable. This is an hdmi lockup problem sometimes related to component video inputs depending on firmware version.

you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Many set have two differant convergance settings one for 480 and one for1080 this is because when it changes mode the set runns a differant frequencys, what may have happened is you have a cold solder joint somewhere that takes this fifteen minutes to corect itself, might want to start by resoldering the convergance and high voltage curcuits
