Question about Mitsubishi DiamondPoint V50LCD (Black) Monitor
The vertical lines are two inches wide and are perfectly straight so I know it's not dead pixels. One line you can sort of see the curser in and the other has little bits of static distortions in it (like a TV with bad reception). The rest of the screen looks fine. I think it's just a loose wire in the back. You can even see the lines if you just turn the moniter on without the computer. I've tried different connection cables.

SOURCE: thin vertical line
What you have described is definitely some form of Electrical Interference. Interference can come from a variety of causes. Is the Cable Inputting the Cable Box close to some High Voltage Electrical Lines? Or Are you located near some Electrical Power Station? Or A Police station, where the Radio Transmitter of the Police Station causing the Interference? As I said, there are a variety of reasons. Also, Try to check if the connector is loose at the rear of the Cable Box, or at the rear of the TV. You will have to eliminate every possibility reason. Wish i could help further.

This sounds like a bad connection or a bad capacitor in the 220 volt source that supplies the voltage for the CRT boards. You will need to get a schematic and trace out this voltage from the PM board to the CRT driver boards when the set acts up. it could even be a connection on one of the plugs from the PM board to the CRT boards. Sorry but not a real easy repair. Might take some time to trace unless a component is failing. Good Luck

I assume your Misubishi is not close to anything electrical. However, it sounds like you have had an interference for some time. This will ineviteably cause the HDTV LCD to collapse. LCD's don't respond well close to heat. Is there a vent close? LCD's do well in a properly vented area but with all this said.......they will pick up interference from anything electrical. A few questions to ask ones self........are there any wireless devices or chargers close to the LCD? Might there be an oven, a/c unit or other wiring with 220 volts anywhere close to the LCD such as in the wall?
The Mitsubishi LT is a very reliable, multi component ready set that allows great viewing with surround sound. However, stop and think about this interference. It is not something in the unit. It is an interference. Look hard and when you've discovered it.....you won't believe how crystal clear this set will be.
Let me know what you find...Thanks for using Fixya and add any comments that may help us help you.

Usually when there are colored lines on the LCD its because the screen is going bad. Quick way to verify this, try a different monitor on your computer and if the line goes away then you know for sure the monitor is bad.
If you try a different monitor and the line remains then you know that the video card is bad.
