No Power When the power and monitor cable are connected to the computer there is no picture and the power light is not lit. Pressing the power button does nothing. However, with the power cord plugged in and the monitor cable not hooked up to the computer, the green power light is flashing, and the power button seems to work as pressing it will make the flashing of the power light to stop flashing.

Re: No Power

This is a very common problem. Theres a guy on ebay that will fix it for you for 24 bucks plus 5 bucks shipping. When you open the monitor, on the back panel there are 2 boards. One is a power supply board, the other is the interlogic board. The power supply board is where the problem is. I do not know the exact component that needs replacing as I did not test this yet. I do not have the proper test equipment. For 24 bucks, I'm just gonna let the ebay guy repair it. I will report my results here when I get the board back. I'm also gonna mark the components so I know what they replaced.

Re: No Power

Hi, It's either the LCD monitor is not receiving video signal from the PC or something is wrong with the input circuitry of the monitor. 1. If it is the PC, it could be anything from the video card, memory or something else; 2. If it is the monitor, you have to open it up and diagnose the problem. This would probably require component level repair. You have to be familiar with the use of a soldering iron, a VOM and circuit analysis to be able to do a DIY. If you can borrow or have access to a known good 2nd monitor you can confirm which one is the issue, PC or monitor. Hope this works out for you. Pls post again how things turn up that we can further resolve the problem. Good luck and kind regards.

"monitor has a green tint AOpen f2915"

moz-screenshot.png The solution: a hidden menuwithin the main menu itself. Hold the Menu button down while pressing Power topower on, and release power button only when the screen comes up, still holdingthe menu button. The menu will appear and there will now be a hidden selection,"Auto Color", printed in a red-on-black font at the bottom of themenu. Use the +/- buttons to access it, and press Menu. My green/yellow tintwent away! Now my picture works great, and the setting lasts throughAuto-Adjusts and Resets!

Monitor will not power on

In front the LED should come on oarnge even without the macbook when pressing the power button, if you have a meter check that the adapter measures 12V.

If it does, check the mainboard capacitors and diodes and the inverter, follow the voltage from the adaptor plug.

No picture on monitor 997M

One reason that this is happening could be that it is on Power saving mode. This happens when the LCD monitor detecs an incorrect timing then thats the time that the LCD goes blank and the power botton starts to blink.

what you need to do is to turn the computer off. Unplug cables attach to the LCD make sure it is also off, once done press the power botton for a couple of 30secs to a minute and then release. After doing so re-connect all the cables and make sure that both ends is tight and secure once everything is ok turn the computer on same with the monitor to check if it solves the problem.

Green Power light blinking

Check the resolution in the Windows while connected to the old monitor. If greater than 1280 X 1024 and/or the refresh rate exceeds 75 Hz, the monitor may not respond. But you should at least see the BIOS splash when the computer is turned on. If that does not appear, maybe a problem has occurred in the monitor. Another indicator: if you turn the monitor power button off and then back on, you should get some sign of life such as "no signal", or "out of range". If nothing appears, that would indicate some problem within the monitor.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!
