Whenever I hit any of the bottons on top of it (poroperties,auto adjust, and volumn button a grey box appears on the botom righthand side of my screen and the bottons become unresponsive.
SOURCE: 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 ****! ;)
Certainly, if you jumper the connections to see which ones turn the monitor on or off, then you can go to an electrical supply place and get a micro switch and wire it in in place of the power button, or perhaps find a type that is flat that the power button can press. What you need to determine is if it is a push-on, push -off type switch, which always stays on or off depending on position or if it is a momentary interrupt switch where the button pressed momentarily turns it on and then releases and a second press connects the circuit to turn it off. You can do this by testing with your jumper wire, attach it and if the monitor stays on when you remove it, then goes off when you attach it again, you need the second type switch, if it goes off when removed, you need the always-on always -off first type switch. .
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!
