Question about Samsung SyncMaster 204B 20.1" LCD Monitor
When i turn on my pc and monitor the monitor stays black for maybe 2 minutes, eventually you can see the picture dim and flickering. after maybe another 2 minutes the picture is viewable but the picture is weak. after another 5 minutes the picture is ok. but if i shut the monitor down for say maybe 5 to 10 minutes it does the same thing again. What is wrong with my monitor?
FIXED: I took the advice to replace C110 and C111 with 1000uF 35V
and a pretty easy time prying open the case with a medium-small flathead screwdriver, disconnecting a few connectors, 4 silver screws (2 on the left & 2 on the right of the LCD), 2 black screws on the back of the metal case, 3 black and one brass screw on the PC board, and
it works like new.
HINT: Be sure to insert your new capacitors correctly (positive and negative sides). The capacitor has + and - sides (the - side was marked on mine). The bottom of the PC board (where you apply solder) has a + marked on the positive side.
For the faint of heart: I am an inexperienced and HORRIBLE solderer and know close to nothing about capacitors, resistors, etc. So, if I can do it you can too!!!

Repair verified! My local elecronics supplier had the correct 1000uf caps in stock, and my 204b is good as new.

I sent my monitor back to Samsung for repair.

Had the same problem here !
C110 and C111 on the power supply unit are busted.
I replaced then with 2 ELCO's from 1000 picofahrad 25 V.
Voila!! runs like new.
