Question about Zenith P50W38H 50 in. Plasma Television
After about 10 minutes the red and green pixels start to shimmer and the screen blinks every 15 seconds. The blinking increases to every second or so after a few more minutes. If I interrupt the video by opening the DVD tray the screen is fine for about another 10 minutes. It also had purple vertical bars which started weeks before the pixel and blinking problem.
Sorry to tell you, it is not a scratch, but a bad cable connection from the driver IC's, connecting up the plasma screen to the drive board, or the drive IC for that section of the screen is defective. It is not a repair a user can do as there are no user replaceable parts inside this set. Your going to have to call NEC or an experienced Plasma repair shop.

More than likely this is a bad display (lcd screen) the drivers in the lcd display are going out and unless its under warranty its very expensive to repair. Sorry :-(

Sound like dry goint on Power Supply bord. I had the same problem and resolder most of the parts of the power supply and TV was ok.

dont get mad like i did, report this problem to zenith, they seem to be aware of the problem with this particular model.
i gave them the model number and they requested the purchase date, then extended the warranty and gave a number for a local repair shop which came for my set a couple days ago.
so far so good. it may be a while until i know whether the repairs will work, however hats off to zenith, so far, which seems to be providing appropriate customer service and standing by their expensive products.

this is called cell mis-fire. sometimes this can be adjusted by a qualified service technician and repaired. however most times the " y- main " board will need to be replaced
