Philips 50PF7220A/37 Grainy/Snowy video

My 2 year old philips 50' plasma screen has started displaying a very "snowy" picture. This is most prominent displaying a black/empty screen you can see white and colored pixels across the whole screen. This happens on all inputs and is not snow related to poor reception/signal. The same condition exists if displaying the internal menu. On the empty/black screen a horizontal bar where the "snow" is more visible appears in the center of the screen. This bar or rectangle takes up the entire screen except for 3 or 4 inches at the top and bottom. This was originally intermittent. Would display for a few seconds and then disappear for an hour or two or more. It almost looked like some kind of RF interference which appeared while the RFI was present and disappear when the source of RF was removed. It is now solid. I am thinking that this is a power supply issue with electrolytic filter caps starting to fail. Could you point me to a possible fix ?

    Yes similar problem, as I had/have the same problem we even returned it for repair under warranty , which they updated our software (was all they said) and couldn't find any other problem , now the TV is out of warranty the problem has risen again , the picture will start off snowy then gradually increase with distortion of the picture until the whole screen is all grainy/colored snow stretched across the screen this can last up to 4-6 hours , on some days this can happen and go away within an hour

SOURCE: my picture is really snowy

Capasitors on the power suply are failing or they have a cold solder joint. Take the back cover off and run a fan on the power suply to see if this problem stops. If it does the run smaller fans to track down the bad capasitor. There durt cheap to replace!

SOURCE: NO VIDEO

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.

SOURCE: Picture Problems On 50 Inch Philips Plasma

You plasma still under manufacturers warranty. Most electronic devices have one year warranty.
The failure in your TV can only be corrected by repairing it.
I would suggest to call philips and ask them to find you an authorized repair center near you to get your TV fix under their warranty.

SOURCE: P42HDTV Visio Plasma TV. The picture is bad grainy/snowy.

Doing some warranty work for Visio, I ran into this same problem. I replaced the video and power boards, among other things. Turned out to be a bad panel, which isnt viable to replace. Best to get Visio to agree they made a lemon (as all their products are in my humble opinion) and have them send you a new tv, or even better, buy a tv that is NOT a visio. You can get great deals on LG and Samsung these days, both decent quality tvs.

I have a seven year Plasma TV HP PL5060. When I turn on the TV, I have sound but no picture, the screen display (power on) is a snowy blue screen and vertical pink stripe. What is causing this problem and how can I fix it cheap. I can afford a TV repair man at this time, because I am laid off from work. Thanks.

I turn on my 50PF9956 get sound but no picture. For 2 weeks before it started taking longer to get the picture. I tried the menu with nothing


The plasma picture tube technology lasts only 24 months before it burns itself out, requiring a new
plasma picture tube. The LCD and LED technologies do not suffer from this short life span.
If your Philips 50PF9956 is over 2 years old, you've got all the use your plasma can give.
Fix: new plasma display - the electronics controlling the plasma display are most likely fine - just
like the electronics providing audio to the speakers. Your set's only problem is a burnt-out display.
