Samsung Syncmaster 204bw has a red screen


A red or pink tint to the screen indicates that the back light bulbs are failing and are about to burn out. Its time to look for a new monitor.

I have a samsung syncmaster 204bw and sometimes the monitor flashes black for a couple seconds and then comes back on. it will do it and then wont for awhile.


This is an early warning that the inverter board is failing, "powers the back lights behind the screen" eventually it will go. The board must be replaced or repaired.

My monitor plugs in blue power button blinks why ?


There is probably a failure of part of the power supply pcb. If the light blinks and the screen is totally dark, this is the likely cause. The usual culprit is decective capacitors on the pcb. See other posts on this subject here. This failure may be intermittant; in other words, it may not always occur.

Problem with syncmaster 204bw


Hi there.
unfortunately this is not a driver issue. if possible, test this screen on a different PC/Laptop.
it sounds like a problem with the screen itself - meaning you will have to take it to a service centre, or if its under warrantee - take it to the shop you baught it from.
*** NB note: samsun screens normally carry a guarantee of AT LEAST 3 years, and not only 1 Year.

Samsung SyncMaster 204bw....keeps going black every now and then with the power light flashing, i don't understand what is wrong with it :S please help?? i have to restart my system everytime...


Similar problem with Samsung Syncmaster T260 at 1920x1200 on HIS Radeon X1950XTX video card. Black horizontal stripes lasting 1/60th of a second or so every few seconds, then black screen for 2 seconds, then fine again.

I Set the catalyst control center control panel for the graphics card to Alternate DVI operational mode under the Digital panel attributes item. Setting the screen to 1600x1200 also seems to stop it doing this. BUT...it didn't used to do it. Bought it in November, and it didn't start doing this until late January. Go figure.
