Samsung SyncMaster 240T issues

Thanks for your time, ok I have a Samsung SyncMaster 240T, it was working great. Now when I boot up everything looks ok, but when Windows or OSX starts it beeps and keeps flashing in and out. Now I cant get it to work for a little a bit at 800 x 600. but not long. It can't handle the high res settings any more, I had that thing at 1900 x 1600 at one point. thanks

A red or pink tint to the screen indicates that the back light bulbs are failing and are about to burn out. Its time to look for a new monitor.

Follow the instruction below to solve your problem:
Restart your computer and enter Safe Mode (press F8 right as the computer starts booting up. Choose Safe Mode in the menu, press Enter twice).

While in Safe Mode, open Control Panel and go to Add/Remove Programs (Programs and Features on Vista/7) and uninstall the display driver software/drivers.

Restart your computer and boot normally. Now you should be able to see everything. Things might look bigger and uglier, that because there's no display driver installed. All you have to do now is reinstall the display driver. Use it's original disc or go to the manufacturer website and download the latest driver.

Good luck!

My Samsung Syncmaster 240T stopped working today. I tried turning it on, and it starter emitting a constant short beep once every 2 seconds or so, along with the green Video light blinking every time it...


Your Back light inverter power board has died. The beeping and blinking are caused by the power board repeatedly trying to start up and failing. This is a common failure point of LCD monitors2.gif after a few years of use. The heat build up in the monitor case causes parts called capacitors to blow leading to the power supply short. If you can solder you should be able to do the repair. Go to our web site at: We have pictures of what to look for. Now take the back off of your monitor and replace all of the caps that look like the pictures and you should be back going again. Be sure to use high temp parts, they will be marked 105c. The values you will need to get will be marked on the sides of the bad ones such as 220uf, 470uf or 1000uf. When you insert the new ones be sure to put the polarity stripe going the same direction as the old one comes out. If you have any questions just let me know. If you don't want to do the repair yourself we do offer a repair service for $30 + return shipping2.gif.

The power lamp is blinking orange

Make sure it is plugged into a computer with a working video card. If error code is still there you have a main board problem. Who is the manufactorer?

I too have the same problem with the same monitor.. tv looks great OSD looks great.. pc is dim.. This has nothing to do with the inverter board or the backlight.. I believe that there is an issue with the components that render the Computer video.

Display doesn't turn on, emits short beeps and blinks lights

Sounds like a low power problem, Check the power supply with a good ohm meter set to DC voltage if voltage is less than 14 v. Replace the supply. DWW
