Check the DC filter caps in the power supply section.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Monitor to black, power LED blinks, hard re-boot and it works


Take a look at your power saving settings. It sounds like the monitor is set to sleep after 20 or 30 minutes. You may want to change your setting to "never". The settings are under Control Panel - Power management

Syncmaster 932Gw stays in standby


Its possible that the cable from the laptop to the monitor is damaged. I would #1 make sure that the connection into the pc and into the monitor are both snug, if they are just slightly off it will keep the monitor from powering on. If they are snug, try another cable (if you have one) or hook the monitor to another pc (possibly your laptop, if it has a video out). Let me know if that solves the problem.

hello
I am a technician-informatic. I have repaired about 80 Lcd Samsung monitors with theese problems. I offer the repair manual.
Manual has been done with the experience of the repairing Samsung Lcd monitors. Manual was made by me and shows how to open monitor, how
to solve dark screen problem, how to check and replace capacitors, how to solve the problem non-optimal mode (without reprogramming MCU or
changing the main board) photo are included. 100% functional. The repair process is very simple 30-40min. (does not need a lot of
experience in electronics and expensive instruments) and is not expensive. With this manual you can solve problems by yourself and save
money.

"Not Optimum Mode 1280x1024 60Hz"
- The monitor turns on but turns off by itself, the LED blinks green.
- If you detach from the PC points to "control cable" the picture runs continuously in the vertical direction or presents while line , and
as soon as it is reconnected, the monitor goes off.
- The monitor does not turns on and dont dispaly anything, the LED blinks green-lit, if you detach from pc points to "control cable".
- The monitor turns on, works well some time, but after a window apiers "Not optimum mode. Mode recommended 1280X1024 60Hz"
- The monitor turns on, works well only with low resolution 800x600, when try to change a window that reads "Not optimum mode. Mode
recommended 1280X1024 60Hz"

the manual you can find on ebay (my ebay name is asnerejas123):

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
