Black Picture I had just bought this TV (Philips 50P8341A) and got it home for a few days it worked perfectly. Now all of a sudden the picture screen is like going black and stays like that for a minute and then the picture comes back... and it keeps repeating this.. sometimes it will stay on for awhile, then starts to go black again. Can someone maybe give me good advice on what could possibly wrong. I was going to get a tech. to look at it, but its going to be expensive. Thanks!

Hi, i bought a wii a few days ago and like everybody else mine too was in
black and white with a grainy picture. I have a Panasonic lcd flat
screen and thought I had connected it corrected, I got somebody out to
have a look at it and found out there are some connections on the side
of the TV which I hadn't even noticed before, once I put the red white
and yellow leads in these and set the TV to AV3 everything is in
perfect colour. Hope this works for some of you.
you need ssb board is bad and you can,t git that part you can send to pts to have it rebuld. yes the stk 392-120 can drag the pix down but if you open it up you see a fouc blook go to the screen red or green or blue turn it up just a litte the pix will come back. this is a know fact about this with this set i see a lot in my days of sevice ,at quaker tv
I would first check if there is an available firmware upgrade for your model .Upgrade requires you to download firmware from philips website.Then transfer it to a memory stick .Then use a memory stick reader to plug into tv for firmware upgrade.Other wise the set would probably need repair .Possible a bad SSB board or another issue
I realized that there is a 90 day warrantee on parts and a 30 day limited warrantee on labor for the repairs that were done. As I stated, the original problem was the picture shrinking after a few minutes of the set being on. The repair firm took my control board with them. When they came back to install the repaired control board in my set there was a load spark during the installation, after which I had a black screen and no sound. The repair firm took my set them and installed a "CAP Kit", a STRM6511, and a "D1881". The set worked perfectly until two days ago.
I called the repair firm an they are coming out this Thursday to check out my TV. I am hoping the problem is related to the failure of one of the parts installed to fix a similar problem which occurred after the sparking incident.
If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on. If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.
