Question about Philips 42PF9630A 42 in. Plasma Television

1 Answer

Screen goes black, picture grows over time but is dark

We have had this plasma TV for almost 3 years. We bought it from Best Buy without an extended warranty. We have had few problems over that time except for the screen often turning off for several seconds, then coming back on, which seems to be a frequent problem reported on these posts. Then last week, we turned it on and the screen was black, and the picture started to slowly grow from right to left, like mold growing across the screen. After about 20 minutes, 80% of the picture is visible, but that picture is very dark and hard to see. The sound is fine. We have called Best Buy and Philips, but they have not been able to provide a solution. From looking at other posts, I think this might be a panel or small signal board problem. Is this something I can fix myself, or do I need to get it repaired by a professional?

Thanks for any help that you can provide!

I suspect that you have a problem in the yb board that's the first thing that i would do.


good luck

LG 50inch Plasma received loud sound then went black


I suggest you guys take your TV's into a repair shop like Sears or Best Buy... The main reason most plasmas go dark is because of decay, but I don't think this is the case. Because what you describe is similar to what happens in LCD's when their back light goes out. Although you can open up and repair the back light your self in a LCD, I would not advise you to do so for a Plasma, because of the hazardous chemicals used in the plasma display plus the fact that plasmas don't use back lighting. And 2 years is way to soon for decay to be a factor. So more than likely a circuit shorted out and the TV has to be opened up to be repaired.

Hi Mikshanks,

I had the same problem with my TV. It was a horizontal problem with different shades of color, and black spots. I replaced my Upper & Lower Y-buffer boards. Your Y-sus board should be okay since it still powers on the screen. You should replace the Y-buffers Upper & Lower, and it should work. I hope this helps.

best regards,
Tyler

TV flashes to black and back again, no remote control operation..


I had the same part replaced in my KDF-42WE655 (3 YEARS OLD) television about 6 months ago and it was covered under an extended warranty by Sony because of a defect found in the part after manufacturing which Sony found will malfunction after time causing multiple issues with the television. My issue was the bottom of the screen started to get a blue dot that was getting progressively bigger. I bought the extended warranty from Best Buy and the problem was fixed no charge but the technician told me that Sony is aware of this issue and they extended the warranty on this part because of it. I would start by calling Sony and letting them know of this issue and see if it's covered under this extended warranty. Hope this helps

I have a Samsung 50" plasma, that has been blacking out over the last 6 months. A 9/2005 set. Now its practically unwatchable as it happens 3 times in an hour. Its not heat related - I have a high volume 9" fan activated on TV power on. Turning the set offf/on usually makes it come back for a now short while. Considering to go put it in the back of my pickup and park it in front of Best Buy and discourage Samsung purchases. This is the 2nd Samsung TV I've purchased (the other a 32" tube) I gave to my folks a couple years ago and its gone bad as well. Samsung product may look good, but their video engineers are not.

42 inch LG Plasma TV - Lost picture


Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.
