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

1 Answer

Convergence issue resolved but concave picture remains

My almost 4 year old Philips 55PW9363 worked fine during one of the hottest days seen locally. I turned the set off and had dinner but after turning the tv back on a few hours later the colors were not aligned. I reset the red and blue settings which helped somewhat but had to adjust all multi-point settings for both red and blue. The picture is now clear and the colors correct but the top and bottom corners would not align during the multi-point adjustments as the picture is not squared off. The top and bottom curve in toward the middle and the left and right side do as well. This did get slightly better after a few hours but still remains a problem. There are no menu adjustments for aligning the picture and inspecting the internals only show hold down bolts on the main tube display rack. Is this correctable? I initially thought possibly the reflection mirror was out of alignment but can see that the projection has the curves in it and the mirror is just showing the actual projection. Any help would be appreciated.

Philips 55PW9363 hd tv has sound but no picture. Was working fine before it was turned off and this happen when it was turned on about an hour later.

You may have a bad, small signal board. Once in a while you may get a picture back....if the TV has been unplugged and plugged in after a few days.

Convergence Issues...

Yes the Ics are easially replaced if you can solder. You will need two STK392-560 Convergence ICs and possibly the 12 4.7 ohm 1/2 watt resistors as Sony sets will usually weaken the 4.7 ohm. You can get the replacement ICs ad resistors at the following link and they provide free instalation instructions with picture as well as free online tech support in case you need additional help. Here is the link.

Philips 55PW9363 looks 3d

You need to replace both convergence ICs they are STK392-120 this is an easy repair that you can do yourself and save yourself around 400.00 for about 45 minutes work. You can order the new ICs at the following link and they provide free installation instructions with pictures and also free online support with a support tech while you do the repair. I am one of their support techs. You would also want to order at least 4 convergence resistors and they send the proper ones for your model as often a couple resistors go. Your model uses 6.8ohm 2watt 5% metal film resistors. So to recap you will need (2) STK392-120 Convergence ICs and (4) Convergence ICs . very inexspensive repair if you do it yourself. here is the link.

If you are doing the labor you should wait and replace the new part and while you are at it check for loose conections in the horizontal drive circuit since all symptoms might be related,but they are doing all the work they should address all the problems you have,settings in the service menu dont just change on their own and are adjusted only when a major comp[onent has been change like the convergence.
