Toshiba LCD 37" with gray band and blue line

sounds like the same problem as with most screens. it could well be the screen as gone

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.
Take it to a repair shop.

This is an easy fix using the Philips remote control that came with your tv. On the center of the remote is a dial that has left right up down controls. Stand in front of the tv and using those controls you can recenter the screen and get rid fo the green line. I had same problem when we hooked up hd satellite reciver to philips 37 plasma

I have a Toshiba LCD TV .a very light shadow on the screen just to the right

the problem here is the Lcd controler or T-con board. The problem is Toshiba does not alway sell the board seperately you may have to buy the complete LCD panel Call toshiba Tech support or check on their web site for you particular model

COLORS OF LCD SCREEN HAS TURNED TO PINK AND PURPLE WHAT TO DO NOW?

Same Problem Here on different Toshiba Model. Did you get it fixed?

remove the ground from the plug

You might need to play with resolution of your laptop.
Display-properties-settings-resolution.
You can use S-video or S-video-HDMI cable.
Good Luck

THIS IS MOST LIKELY TERMINAL. YOU NEED A NEW PANNEL. YOU CAN TRY TO TAKE OFF THE BACK COVER AND RESEAT ALL THE RIBBON CABLES THAT GO TO THE PANNEL. IF THIS DOSEN'T FIX IT, BUY A NEW TV.
