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"

It is inside the LCD the at the main board. You have to repair the board to make it function.

Its a general fault however all these units are under a 3 year warrantee the dates printed on the back, just call 08706010309 speak to a service engineer and they will arrange a swap out within 5 working days, no need to a receipt as they can tell the units age from the serial. the replacement will be under the same 3 years cover in my case it was for another 6 months

first, try the internet...http://www.pricegrabber.com/ and search for your model and then for optional accessories. if no-go, then... remove your car battery, then devise a makeshift 2-wire cable to deliver 12 volts to the proper pins on the back of your monitor. look for polarity markings 12v at 6.5 amps (70 watts) may be hard to find as a "universal" supply. many older pc case supplies (pre-ATX they are free at recycling centers) have the 12V available...just ensure the yellow and black (ground) wires only are used...may also need to ensure that "power ok" signal is set to activate said supply

You can go to http://www.fastrepairguide.com , they have a lot of free service manual, included lcd monitor, lcd tv, plasma tv & etc. May i know, what's your lcd monitor problem?
