Hello
\015\012I 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
\015\012to solve dark screen problem, how to check and replace capacitors, how to solve the problem non-optimal mode (without reprogramming MCU or
\015\012changing the main board) photo are included. 100% functional. The repair process is very simple 30-40min. (does not need a lot of
\015\012experience in electronics and expensive instruments) and is not expensive. With this manual you can solve problems by yourself and save
\015\012money.
\015\012
"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
\015\012as 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
\015\012recommended 1280X1024 60Hz"

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors\015\012will blow a power supply. The problem is caused by parts called\015\012capacitors overheating in the confined space of the monitor. If you are\015\012good at electronics repair/soldering you can usually fix the 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 pictures and your monitor should work\015\012fine. The capacitors do need to be installed with the correct + and -\015\012connections, note the stripe on the old one and insert the new one the\015\012same 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.
