Question about Hitachi Computers & Internet
Use to have the Windows XP Power Monitor set to turn off the monitor after 5 minutes of inactivity. When the mouse or keyboard use was sensed it would turn back on. This no longer works. It still turns off but won't turn on unless I reboot the computer. I can still get almost the same effect by using screensaver set to a blank screen. Screensaver still works. I've tried the monitor on a couple different computers also using different cables, so I know it's the monitor causing the problem.
*check the power cables
*check the power outlet
*check smps is fine
*check power switches are properly connected
*check in bios hdd is enabled
*open the case wheather the connections are properly connected

this is a common problem when using wireless equipment in windows. Especially on Dell notebooks. The PCMService.exe program starts when the computer starts and interaction at some level between this and the Wireless reciever prevents the computer from becoming idle. Therefore, the screen saver and the other idle-related features do not start. this issue may also occur if the PCM and DVDLauncher services are running in the background. This issue also occurs in Windows Vista premium and in Windows Vista Ultimate because of the media center functionality that is built in.
Microsoft reccommends plugging in your wireless device and visiting http://windowsupdate.microsoft.com/ to get the "optional hardware update" named "Microsoft HID Non-User Input Data Filter." This should fix the problem.
Microsoft also reccommends two possible "workarounds" for this problem if you do not want to install the update or if the update does not work, both are relatively simple:
1- turn off the PCMService.exe program. to do this, first you open the system configuration (start->run->msconfig.exe). on the startup dab of the configuration window, click to clear the PCMService startup item check box. Apply, Close, and if/when prompted, restart your computer.
2- Remove the PowerDVD Software (not advised if you use this software for watching DVD's on your notebook). To do this, open the add or remove programs window (start->run->appwiz.cpl), locate PowerDVD, click change/remove, and follow the steps through for removal of the program.

Not a solution but it may bring some light to the problem,
There is some program calling windows every 10min or so... that's why your screen saver gets interrupted. You might need to check which program is it. Or guess it out.
Hope it helps, if you have more doubts feel free to ask.

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.
