Even after replacing the capacitors still same what else could be the problem???
Posted on Jul 23, 2012
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
"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):

Yes, look for two 1000uf capacitors on the power supply PCB near the output cable to the main PCB. They will have swelling and discolouration. Replace those and should fix your problem.
