Question about Scanport GL 821A 17 in. Flat Panel LCD Monitor

1 Answer

LCD powers off and on repeatedly

Hey all, I've been having a problem with my monitor where it turns off and back on every second or so and repeats indefinitely. The problem seems to go away for a bit when the monitor has been off for some time, but always comes back. It also seems to be somewhat related to what's on the screen. One time I switched from a mostly black screen during the cycling to a mostly white screen (a word document) and the cycling stopped for a bit. It eventually picked up again though. I've tried some of the other solutions that others have posted for similar problems like mine (boot up in safe mode, reinstalled video drivers, turned down video settings), but no go.

    Oh, adding that it has this problem even when it's not hooked up to my computer.

SOURCE: Flat screen will not turn on.

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 tech@ccl-la.com if you need any more information about the repair.

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

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.

First of all check if the monitor works in another computer.
Pay attention at your computer beeps when you start it up.
If there are a series of repeated short beeps it means that there is a problem with your video card.
If there is a long beep that repeats, then its a bad memory module.

Fix one of the three, and you'll have your image back. Good luck.

Monitor flickers and goes blank after 5 seconds and keep repeating this very often.


Hello,

If you turn the monitor off then about 1020 sec turn it back on and have a picture for five sec again it sound like the power supply in the monitor. but if that did not solve the problem, the picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault and will need to be replace.

I advice you replace the picture board on the screen of your monitor to solve the problem of the blank screen.

Take care.

You need to open it up and inspect the capacitors (look for bulging top/seal), burnt inverter transformers, resistors, etc. in the power supply/Inverter board first, post back what you find so we can guide you further.

Hello

Probably the monitor. LCD monitors use electrolytic capactors which change value with heat. The power board in yours probably has 6 to 8 caps whic need replacement. Take it to a reputable repair person or check out my websit.
