Hello,

The picture board on your monitor is bad, since the power or button is on and sound and other things are fine, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

I don't have the driver for this monitor and I could not get the proper color, it is faded. Where can I download for free the driver


That is not monitor driver problem, the monitor driver will enable the PC to be able to set the proper resolution. You should try it with another PC first. What do mean by cannot get proper color?

My NEC Multisync LCD 2080ux + has developed a weak display which makes text harder to read. I have adjusted the ATI Radion 9600 graphics card with no success. Any ideas?


One thing that will affect how clear the display is if the monitors resolution is set to the wrong value. your monitor must be set at at its native resolution of 1600x1200. Any other value will result in a degraded display.

I CAN'T READ THE BLUE TEXT IN MY E MAILS


If Blue colors display properly in pictures or graphics check the display and size settings of your computer in relation to the size monitor.

If there is a problem with the blue color because of a problem with the monitor you might be able to compensate for it either with controls on the monitor or with the control software of your video card.

My NEC mt1075 projector is projecting a shade of blue all over. The entire screen is showing the correct image, but also with a shade of blue. I think something is wrong with the internal wiring. Is this a...


If you're using component video (red/green/blue rca cables) one of the colors may be disconnected, or the wires may be swapped into the wrong color input. If you are using a 15 pin VGA connector, one of the pins may not be getting good contact at the source or at the projector. Or if the VGA cable is split into 5-wire to make a long cable run, one of the five wires may be disconnected. Any of these problems will cause a global color shift while not affecting the color of the projector's on screen menus.

Red colour missing


- A bended color pin at the VGA connector. (If pin one is bend then there would be no red color)

- A defective VGA signal cable. If the internal wires were broken then there would be missing colors. You can check if the signal cable is good or bad by doing a continuity test using a multimeter.

- Dry joints in the CRT board such as in the CRT socket pins, video pre amp and driver IC and even at the connector pins. In fact this problem contributed about 80% of Monitor color problems. Applying fresh solder would usually solve the color problem.

- A defective IC either in the Video Pre-amp or Video Driver IC.

- Faulty components in the CRT board. It could be a shorted driver transistor or even electrolytic capacitors that the ESR reading had shot up!

- A bad CRT socket. Sometimes decayed glue could cause the internal pins rusted and thus affecting the colors. Replacing only the CRT socket would definitely solve the problem.

- A weak or a defective picture tube (CRT tube). Yes, I do came across one of the electron gun (most probably the cathode materials had used up) in the tube faulty caused a missing color in the screen. There’s no way to repair this type of problem-the only way is to replace the CRT tube.

- In the newer type of Monitor, color setting is save in the EEPROM IC . Thus, if the EEprom data is corrupted, you would also get a missing color! The only way to repair it is to reprogram the IC or use a soft jig to tune it back the color setting.

Shows nothing but cross horizontal bands


The monitor may not be able to handle the settings of the video adapter. If you boot into safe mode (tap F8 key as the computer starts), does the display appear correctly? If so, then you just need to turn down the settings (resolution, color quality, frequency) to the lowest possible settings. If the display still appears wrong, then it may be something wrong with the monitor. You can try connecting the monitor to another CPU and see if you can replicate the results.
