No color on one channel

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

This is a screen tab fault and in most cases will require the screen replacing

Check the fine tuning for that channel.Adjust + or - accordingly, see what happens?

Your welcome ! please comment. Thank you !

If you can see white, then all the CRTs are functioning. Make sure that the channel is set correctly. If the DVD is sending out channel 3 and the TV is set to channel 4, you will see the picture, but in B&W, Check that first. Let me know if that does not resolve it.

Thanks,

The degausser cricuit may be the fault. The degausser coil may be staying on, and thus forces a shut-down. It is also possible to have a power supply fault that can cause a similair effect.

The set will need shop service.

yes it is your tv since the tech ruled out the cable box.

1.possiable bad tv tuner cost of repair is 120.00

2, picture tube causes this sometimes but rear to be tube.

If you are connected to a HD cale box using component cables IE (G, R & B) then check if either the Red or the Blue has come loose or unplugged as this will cause most HD sets to revert to a black and white picture.

sounds like it is probably worth trying to degauss check this excellent site; http://woil.ws/fixmonitor/ for details of how to try this on the cheap - it works If it doesnt solve your problem, the fact that you are getting different quality from different crt s suggests that they could be the root cause - see if you can get the part number, and get a price you may find it is cheap enough to be worth trying - check also the power supply - poor voltage output can sometimes cause these type of symptoms. Hope this helps, if not post again - some of the other guys know tvs much better than me :)
