Gateway 46 in plasma

My Gateway 46 plasma is just short of four years old and a few months ago the picture quality became quite distorted, in that colors became muted or washed out and outlines are nolonger clear, Many times the background has a greenish tint and the images have a shiny appearance, almost "ghostly" image if that makes any sense. When the tv was brand new and still under warranty, I had to have the y-sustainer board replaced for a different problem, there was no picture at all, but after that, no problems till now. Gateway wants to charge $500.00 just for a service call plus any repair, labor or parts. I haven't found an electronics repair shop in Modesto, CA that will work on the Gateway, the ones I've called so far specifically stated they will not work on Gateway TVs.

Re: Gateway 46 in plasma

It sounds like the gas in your screen has exhausted it's life. From the information I have gotten from different manufacturers, there is about a 5 yr life expectancy on the screens of most plasma sets.
My guess from the symptom you describe is that you will need to replace the screen.

Hi, I have a 42 inch NEC plasma tv I purchased about t years ago, about 6 months ago every now and then the sound would become slightly distorted like a swishing noise shortly after the tv was turned on....

From your description, it is likely that power supply operation is becoming erratic. Because your TV is new, it probably would be worth having it fixed

I have a Hyundai rear television HY5111W.I noticed that picture became distorted then disappeared. Can you help me fix it


Watching standard cable on an HDTV can be quite a shock; the images are likely to be in a smaller aspect ratio, and have grainy or pixelated distortions. Additionally, the use of non-HD compatible devices, such as a DVD player, VCR, or older gaming system, will produce a less than stellar picture.

If you've changed the aspect ratio or your television, or have changed the zoom in or out, you may be encountering distortion that would otherwise not be noticeable. Setting the picture to a 1:1 ratio and turning off any overscan can help ensure a better quality image.

If you're using a system that supports HD, such as a Blu-ray player or an HD-compliant gaming system without the use of an HDMI cable, the image may be distorted. HDMI cables transmit both HD quality digital images and sound over one cable, and provide the best possible picture A/V signals.

I'm having the same problem with the same TV. I called around to repair shops and I guess it's fixable. Haven't taken it in yet but I was told it most likely is a bad module. But this seems to be a really common problem with this television

Most high voltage electronic parts in a tube style television only have a life of 1-3 years. All of your internal parts are due to burn out or fail.

I would give up and sell/give away this tv and buy a new LCD or Plasma version. Repairing and old tube style tv is probably going to cost over 500 dollars. Just put that money to a nice new one instead. I know it sucks to say goodbuy to your old friend, but the era of the tube tv has ended.
