Display suddenly started flashing solid colors. Red, then green, then blue, then white, etc. Nothing on the screen except a solid color (or perhaps a gradient from top to bottom. Menu does not respond, and flashing colors continue even when disconnected from my PC.

I'd start with toggling on the on screen set-up display. if that comes up and is legible, then you know that the screen is working.
What is your video set up to push to the V50? If it's not a supported resolution, the display may respond this way. try downgrading it something like VGA (640x480) and see if that works. (The max resolution shown in the manual is 1024 x 768, so don't go higher than that. It's also 24 bit color (8 bits each for R,G,B, so don't try to push 32 bit color to it)>
Set the output to your primary monitor to 1024 x 768, thousands of colors. Make sure the monitor sees it OK. Now you know the first monitor and cable are OK. Now switch the cable to the V50 monitor. Do you get a signal now? Then the display works. Try putting your primary display on the second cable. Does it pick up anything now? No. Maybe a bad cable.
You can try swapping the cable going to the V50 to go from your primary monitor output port on the computer to your primary monitor. if the primary monitor works OK, then the cable is good.
Depending on the computer system you're on, make sure that you at least have a generic monitor driver installed for the V50 output. Ideally, get the driver for the monitor You can get the driver here (
Hi there, the mode the unit is in is like self test. Try first to disconnect vga cable from pc and see if the there is notification "no signal" poping -up to see if the problem is not graphics. Anyway you can try to disconnect power cord from monitor and wait a while then try again power it on. If all this doesnt help it will be more then good advice to RMA it if still in warranty. Tnx
Kathy...have you tried connecting another monitor to the same video card and computer? It could be...
1. Video card defective
2. VGA cable from computer to monitor defective...look for bent pins in plug.
The VGA cable from the computer video output carries three distinct colors...red, green and blue. Likewise one of these colors may not arrive at the monitor correctly or at all. The results being that all colors are incorrect.
it's in a self Diagnostic test mode.
check to see if the colors are moving in a square arond the monitor and if there is any writing on the screen.
Make sure the wire from the monitor to the computer are plugged in properly- Reseat them. Take them out and place them gently back in. The wires should be snug not tight. they should not fall out by themselves.
check to see if you have a secondary video output from your monitor and if so attempt that connection as well. The computer will normally self recognize an output and a modern monitor will under normal circumstances project an input.
There are three Cathod Ray guns responsible for the millions of
colors.All colors are produced by mixing the three basic colors namely
Red Green and Blue (RGB) at suitable proportion. If any one of the
three guns fail firing then we get improper colors.
(1) Simply tap on the monitor and see the result.(Keep the monitor on during this trial.)
(2) Disconnect the Monitor.and Slap it at the back by keeping it on a pillow with the screen facing down - it will resolve the problem if the failure is due to the loosening of the Head due to repeated thermal expansion and contraction.
(3) check the signal cable for loose connection, twisting etc on both ends - at the back of the CPU and Monitor (it is fixed) -
(4)tighten the screws at the backside of the CPU
