Question about LG Flatron L1750S 17" LCD Monitor

1 Answer

Screen comes up for about 10 seconds, then goes blank

When I start the computer, the screen comes up for about 10 seconds, then goes blank, but the blue light stays on. When I turn off the monitor and turn it back on, the screen displays again for about 5-10 seconds, then goes blank again. The underlying program continues to run. Regbooting the computer hs no effect.

    Thank you! I will try this when I get home tonight. By the way, my monitor, which is a Flatron 15", is about 3-4 years old. Does that make a difference re trying to fix it vs. just replacing it? Is it getting to the point where I'm likely to start seeing other problems cropping up soon?

Hello Robert,

You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

    After replacing the bad capacitors you should have a few years left on the monitor. Since it is a 15" lcd you may want to replace it any way just to get a bigger screen. Let me know if you need any help when you check the monitor.

Try to do this: Just before the Windows start up screen (after the bios loading) press F8 and log in at safe mode settings. If at this mode you can see your screen change the resolution settings at a lower set. Save and reboot normally. Now try step by step to increase your resolution. In case of a blank screen appears at a new setting, don't do anything; after some seconds the monitor will come back to the previous settings. Save and go on.

In case of a problem or clarification, don't hesitate to post.

Thanks and regards

Motorola RAZR V3x Whiye screen problem


I have managed to fix the problem by doing a software update.
I stumbled across the solution..........I had the phone connected to the computer when I started it in the 'boot loader' screen as opposed to just turning it on. This time the computer recognised the phone was connected and through the motorola software update program I was able to update the software and the phone now works fine.
BTW I did lose all my address book, messages etc.
To start in the boot loader screen hold down the * + # + pwr keys all at once.
