Hi,

If you are looking for where to buy power board on your monitor, i will advice you go to any computer accessories shop around your locality to get the power board or you can order online from amazon.com.

Take care.

could be back-light or inverter or just a cable connecting them to the screen

You can try a different cable for VGA. Check if the port is lose. The green light is only indicating a proper power supply to the monitor. The display is very much dependent on the VGA cable. If your monitor also has HDMI port, you can try to connect using that cable (provided the display adaptor also has HDMI port). If nothing works for you, take it to a hardware engineer or local repair shop.

Capacitors failing to hold charge, pressing the power button allows flow of current to the capacitors on the power board, which are then leaking the current rather than "storing" it, there is therefore insufficient charge to power the inverter with the jiuce it needs to light the screen.

Check capacitors for bulging or leaking ( better still get someone who is comptent to do it) . remember do not touch capacitors until 24 hours after powering off, as the can still retain a charge

Hello David,

This is a classic symptom of a blown power supply board. If you open the monitor and look at the power supply board you will find parts called capacitors with bulging tops, they blow out because of trapped heat in the case. We have pictures on our web site at: www.ccl-la.com/capacitors.htm that will show you what to look for and what you need to get for the repair job. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping. Youcan contact us at [email protected] if you need any more information about the repair.

I hope this helps, if so please rate our solution.

could be a faulty cap in the power supply usually the 470uf cause start up problems

H-21 scan port Dark Screen, If you unplug the green light flashes 2 or 3 times ending any activity until completely unpluged and plugged in again. My other scan port works fine using 1st monitor cables. I've used both ports on the graphics card. It's definately the monitor power supply or other componant.

Any ideas?

Hello Sbeban hi!, Most likely you have power supply problems. to fix this you need to replace the power supply board. or get professional help, by bringing it for repairs on your dealer. Now to do it yourself, you need a replacement PS board. Now finding on is difficult. I cannot help you here. search ebay, call your computer shop or dealer. then when you get the refurbish board. disassemble it and replace the old PS board with the new one.

off hand it sounds like a power supply issue. sometimes fixable sometimes not.

Did you check your hardware drivers to see if indeed the Audio Drivers have been installed? Right-click your MY COMPUTER icon, then select PROPERTIES from the menu. When the window pops up, select the HARDWARE tab, then DEVICE MANAGER. See if your audio is installed or if there are yellow exclamation marks under SOUND, VIDEO, GAME CONTROLLERS or under UNKNOWN DEVICES (i could be wrong on that title, but it will be close!!)
