We own a Samsung 50" Plasma...purchased in March 2006 and are noticing "silvery" looking static on the screen whether viewing Blue-Ray or television programming. I have been reading about "error diffusion" on plasma tv's and it looks like the same problem we're having. How is this resolved?
Yes the diffusion problem on your tv is due to the pdp panel aging. What you can try is readjusting the VSCAN voltage, there is a test point marked VSCAN using a DVM you can first check the voltage, should be around -- 190 turn the adjustment counter clockwise this should reduce the voltage, watcthing the picture turn control untill the sparkling pixels stop. That should do it. The panel is starting to age this may occur again until you can't adjust it out meaning a bad panel.

Line faults & possible causes to both Plasma & LCD screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD screen are similar, irrespective of its brand and screen size.
This is know as diffusion. You will need to locate the Vs adjustment inside the TV and vary it up and down by NO MORE THAN 10 volts. If this does not correct the problem then you will need to replace the Plasma panel.
Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the 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.
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.
