Question about Mitsubishi Diamond Plus 73 17" CRT Monitor

Open Question

Monitor shows equally spaced rectangles

I have a Mitsubishi Daimond Plus 73 CRT monitor. Upon turning it on it sequences between white and black screens with evenly spaced 1-1/4" x 1-1/2 inch rectangles. If the screen is white the outlining rectangle lines are black, if the screen is black, the lines are white. It doesn't matter if it is plugged into the computer or not, it still shows the same thing. Is there anything I can do to get an input, or do I need a new monitor? I would appreciate any help. Thanks....Alan

SOURCE: Vertical white line near the left end of the screen.

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.

My laptop is on and plugged to the monitor, but the monitor says no signal

You have to switch your laptop to a different display mode. Usually it's done by pressing Fn key and F8 - look for a description near this key showing rectangle / rounded rectangle, or text "CRT / LCD".
Usually there are 3 modes:
LCD (internal laptop display) only
LCD + CRT - the picture shows on both displays
CRT - the picture shows only on the external display, allowing you to set a different screen resolution, equivalent to the external monitor's optimum resolution.

Starlogic 19 inch monitor gets unreadable screen

Is this monitor a CRT-type? Chances are your picture tube is malfunctioning. This is a common error among CRT monitors. I advise you to replace the monitor with an LCD, as the power consumption is far less than CRT. Plus, it takes less space.

If you prefer a repair option. have someone "flush" the tube. This may fix the problem.

Monitor problem

The reason I had asked if you had tried a different monitor was to determine if it was the monitor or the computer that actually had the problem. That wasn't clear in the first question.
A computer that is having issues will cause the same symptoms you described.
Repairing CRT's is beyond my level of expertise. When I get into a situation like this, I would just replace the monitor. Sorry I couldn't have been more help.
I stopped using CRT's when the price of LCD's dropped.

Mitsubishi monitor is distorting the picture

well first af all ,you never find this "loose wire" because it is a mith. what you have is a "cold solder" in the vertical IC, if you have a solder iron , and the ability to open it (without scratching), and then take off all the shields (without cutting your fingers), and get the solder area (without breaking the Tube). at this time ,it take you 1 minute to solve...!!! iF not... leave it to the repairman!!!.

NEC 77F CRT monitor - displays alternating black \ white crosses

Sounds like its stuck in test mode. Make sure that none of the buttons are stuck in place and does it make any noise while its turned on?

Severe gradient issues / problems with darker grays

So your sure when you go into the monitor settings, and color, it is set to like 9300k or something? It probably isn't the monitor, because the video games you said display just fine.
