Liquid coolant in big screen tv, what is it?


It is a very toxic material called Glycol==if touched it gets absorbed into your body by contact--there to keep the picture tubes cool.

Lens should never be taken apart---if it got on the circuit boards it will short things out and start dissolving leads and the actual board as well.

Mitsubishi rear projection tv is too dark to see picture


This is a very common problem within your projection TV set there is a small red, green, and blue picture tube. On top of the tube there is a lens that focuses the video on the screen. Between the lens and the top of the tube there is a hollow chamber filled with a clear liquid. This fluid is specifically designed to keep the tube from overheating. After about 4-5 years the fluid will start to become cloudy and will will get worse over time. Tvrepairkits.com is a good place to get a repair kit to fix this condition yourself.

GE 46GW947 TV. Screen is yellowed on top right corner with triangle shape a little less than full screen. Cleaned lenses and picture got clearer but still yellow on top right.


If you are able with the set on look into the three lens, what you are looking for is is there an visable liquid in any of the three lens on top?

These sets use a sealed area with Glycol, sometimes it leaks out so it is on top of the inside lens, DO NOT TRY TO REMOVE LENS COVER IF YOU SEE THIS.
