Question about NuTech QL-711V 17" Flat Panel LCD Monitor

1 Answer

Colors in QL-711V shifted to green

The screen was great until one day everything looked too green. Adjusting with the screen controls did not work - neither the preset temperatures, nor individual setting of RGB.

When not connected to a computer, the colors on the no signal message are perfect.

When resetting or running auto-adjust the correct colors appear, but then the screen locks on the bad colors.

Suspecting some kind of firmware memory corruption I tried to disconnect the monitor while it was showing the right colors during the reset. This did not help.

Re: Colors in QL-711V shifted to green

Hi, I had the same problem and I wrote an email to Nu. They wrote me back that I should use the Factory reset feature which you have to go through the Factory Menu to get to. Instructions to do this are as follows. I got to the menu my first try but it has been a pain to get back to it. I hope it will be easier to access for yours.

Hope this helps

Monitor goes black after 5 seconds but has power.

Power Supply inside the monitor is bad, needs replaced. Compare cost of replace or repair. Usually best to just go get a new monitor.

Color problem

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. This can be rectified by
(1) hitting the monitor at the back by keeping it on a pillow the screen facing down - it will reolve the problem if the failure is due to the loosening of the Head due to repeated thermal expansion and contaction.
(2) check the signal cable for loose connection, twisting etc on both ends - at the back of the CPU and Monitor (it is fixed)

NuTech QL-711V Monitor - no picture

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Colors are off after auto adjust

I seem to have found the solution (and the cause, perhaps?) for this problem!

I was having the EXACT same problem with a monitor I'm repairing for a friend. The capacitors on the power supply board were blown (CapXon capacitors, who'd've guessed), which was keeping it from powering up. After replacing the capacitors, the screen worked beautifully. But it had this weird yellow tint!

The strange part was that pure colors - red, green, blue - all appeared perfectly OK on screen. Curiously, the menus would show in the proper colors, except for one: the manual color adjustment menu, which illustrated "Blue" as a sort of off-green in the icon. Auto-Adjust would always fix the colors for a split second, then go back to yellow. Reset didn't fix it. Color reset didn't either. So, exactly the same problem as above.

The solution I found was hidden within the main menu itself, a sort of "easter egg". <b>Hold the Menu button down while pressing Power, and hold it down until the screen, and menu, appear</b>. There will now be a hidden selection, "Auto Color", printed in a red-on-black font at the bottom of the menu. Use the +/- buttons to access it, and press Menu. Voila! PERFECT COLOR! Perhaps this menu was accessed by accident, and calibrated to an incorrect color key. But now my picture works great, and the setting lasts through Auto-Adjusts and Resets!

Hope this helps some people, it sure saved my ****! ;)

You can try to Degauss the monitor. It still sounds like the video cable is bad. That last part you mentioned about the OSM (on-screen Menu) having normal colors comes from the monitor and has nothing to do with the cable or pc. That tells me its the video cable, or the video cable connector (pins maybe bad) or a bad connection somewhere. There could be a bad connector inside the monitor where the video cable is attached to the electronics board. Sometimes those contacts just get oxidized and quit transmitting a signal. They need a good cleaning.
