Re: bad color

This is not a solution, sorry but we are having a similar problem, in that one day all the color just went wonky - too contrasty and red. We sort of fixed it by radically changing the color settings, but can't figure out why it happened...?

Hi Lizzette,
I am afraid your problem is a little technical. Well if you know something about lcd tv technicals, the problem seems to be the T Con board and/or its connectors. Check the ribbon cables and connectors, clean them properly and and start the tv.If it is not possible or it does not work, please consult someone qualified to handle your set. Good luck.

Green tint on picture 60in mitsubishi

Turn the color all the way off---examine the screen to see if black and white or screen green in areas or whole screen.

The other possible issue is tint will not vary enough from green to purple when adjusted.

Two different issues--which do you seem to have?

Contrast really dark but seems to improve after the tv has been on several hours

You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

I can't seem to correct a tint problem. The tv turns on and the tint doesn't change. A friend says it could be a vidoe card?

Go to menue on controller, then Picture, then adjust Color and Tint to you taste. The color ajusts Blue and Green move left more blue move the slider right more green. The Tint controlls red. More red move right less left. Also chech Color temp setting.

Color changed suddenly, no red, just green/yellow/blue

Sounds like the color wheel has gone bad and needs to be replaced. This is located behind the back panel.

Here are the settings:

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

One year old Samsung digital has green color tint; reset doesn't work

One of two scenario. One, you have a bad LDS cable. This cable is found inside the set. This is the cable that is plug into the panel, The other end is plug into the main board. This cable may also just need cleaning. The end that plug into the Panel may have some glue put on it to keep it from getting loose. You may want to unplug it and try cleaning it . Two, You may have a bad panel. In that case you may want to consider getting a new set.

Best regards
