Question about Philips 42PF9630A 42 in. Plasma Television
I have a Phillips ambilight 42 plasma (42PF9630A/37) that is 2 years old. It turns to a black screen after about 4 or 5 mins of normal watching. The power light stays green then it tries to turn itself back on several times. The picture is perfect and there seems to be nothing wrong until the black screen.
Mine goes black with sound, after about 20mins, then off and on again. mounted fan in back cover from computer and no more problem!!!!!!!!!!!!!!!

I just got a call today (referring to my April 5th post) and the exact symptom and fix from "jdbouncer" was conveyed to me by my repair man. 3 red blinking lights, no sound or picture after about 5 mins are the result of a bad SSB board. I purchased my tv from Costco and they are extending the repair period to 3 years total (the 1st year would be covered by philips). I had to get denied service repair coverage from Philips with a case number and then find a costco certified repair shop and open a case with Costco (via proof of purchase / reciept). Costco customer service was great: ordered the parts and my tv should be fixed within a week. Thanks jdbouncer. Costco does not seem to communicate the longer service warranty but this is good to know. From what i have heard, they had too many tv's coming back after 1-2 years and they created a program to deal with them as a fix rather than a return.
Thanks Costco too!

Question when u loose picture do u loose sound also ? If so there is an 27Mhz xtal on the (SSB) small signal board that needs to be changed when it heats up it cycles out of phase. when it cools down it will work again till it heats up.

It sounds like the entire screen goes blank with your problem. My problem is the lower half of the screen goes blank. Do you think the SSB is also the problem? What are your thoughts about the "Video Board" or the X Board?
Do you know where to purchase parts?

Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

The only thing I can suggest outside of taking the television to get repaired is a hail-mary firmware update. To be honest, the firmware update process is fairly complicated and lengthy. You can download the firmware and find instructions for it here.
Look on the right hand side for firmware information.
This TV is likely outside of its 1 year manufacturer's warranty so you would have to pay any and all repairs. Before deciding to do a repair you might try calling Philips. For a while they were offering a service to customers like yourself with out of warranty units. They would offer to sell you a more up to date model at a discount. I'm not sure they still do this but its worth a shot.
Hope that helps!
