Question about Zenith P50W38H 50 in. Plasma Television

1 Answer

P50W38H screen flickers and red and green pixels shimmer

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 :-(

SOURCE: lamp indicator blinks red

There is a problem with the lamp or around it? When it turns Orange, the lamp is at or near the end of it's life & needs replacing. What does the temperature indicator show? Orange, Red or Red Flashing? If not, then there is probably accumulated dust around lamp area

The buzzing is the ballast for the lamp trying to light the bulb. From what you've described it is a lamp failure. It's not that hard to change but you'll have to obtain a new lamp first. You can try and buy it from LG (800-243-0000) but I'm not sure if they'll sell to a consumer. Then you have to reset the lamp timer after you replace it. Hold the mute on the remote and the enter button on the tv at the same time for about 8 seconds and a screen will come up asking if you want to reset the timer. Just follow what it says to reset it.

The screen turns green after playing videos for 20 minures


The Video Controller works off of the RGB principal. RED/Green/Blue pixels. The mix color is dependent on the formation and density of the pixel and rates. When one or more colors are absent the only functioning color will dominate, and it is Green in your case. The screen liquid crystals in Red and Blue are failing and only a screen replacement will fix the situation.

My dell monitor has three large green shimering boxes across the bottom of the screen that I can't get to go away. Powered on and off, unplugged, plugged....


Shimmering boxes and/or LCD screen has spots = this is due to Missing /broken Pixels.
- These are pixels that are permanently off and is a natural defect that occurs in LCD technology.
Solution (1) = Do a reset on All Settings. http://support.dell.com/support/edocs/monitors/E173FP/En/controls.htm
Solution (2) = If Solution(1) does not work, you may need to replace your monitor.

Picture - Flickers/Shimmers


I think the solution to your problem is adjustment, not of the brightness but either the `contrast' which is probably too high, or the `sharpening' if your set has this function. Too much sharpness will cause a shimmering effect, especially where you see an edge between colours.(due to ringing at a very high video frequency). Too much contrast can start to turn the video signal upside down, causing noise on the peak white in the picture. Another cause is if the RF signal into the aerial socket is too large, This can be corrected by an attenuator, costing about £2. 6dB or 10dB can be tried.
