Question about IBM D185-1702 17 in.CRT Conventional Monitor
I got this monitor as a back up from a relative, and after 10 minutes it went blank and started making this chirping sound...led light blinks in sync with the chirping...help?
Hi, you can try lowering the screen resolution, the color quality and the screen refresh rates. Work from there and observe each setting/increment. soon as the monitor quits, press escape to revert to previous setting. I get the impression that you are familiar with electronics, the problem is your monitor horz. freq is playing catch up and eventually fails. Lowering your PC setting then might do the trick. To lower the settings, right click on desktop, properties, settings tab & advance button - Monitor. Hope this be of some help. Good luck

ferozkhan, It could be your LCD backlight giving you problems. With the computer on and the monitor power LED green shine a flashlight in the lower left hand corner of your screen. Look for the ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. Depending on the monitor this is usually an economically repairable problem. Let us know if you have any other questions and please don?t forget to rate this posting.

The monitor is probably on protection.
To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.
If it is computer fault and no video signal , then test:
If it is monitor fault , then the monitor is on protection.
When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.
If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
Try moving the video cable, and if the cable is not built in, then also try a replacement cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.
