Question about Samsung SyncMaster 204B 20.1" LCD Monitor
Samsung 204b syncmaster. Came home and found montior all black and just the power button blinking. Tried re-booting but no go. hooked up my old crt monitor and everything looked good. What could have happened?Can I do anything?
First of all plug another monitor to the VC on your PC and do the same for the SamSung"I over heat"SyncMaster2 053BW.
Oct 23, 2009 - This is how it went for me..I have a Samsung SYNCMASTER 2053BW. I leave my monitor on and let it hybernate when I shut down PC. I'm 3 months outside of my warranty. Two weeks ago something started happening. I boot PC and video doesn't come up for 10 minutes, and when it came up it worked perfect. VC/Monitor/MB?? It became 20 minutes and ...now..I have the analog/digital box in top left screen, power light on monitor flashing, no menu available on monitor and none of the other buttons work for anything. I test the monitor on Laptop..nothing(same as above)..I break out the old(working) monitor from deep within the closet. Plug it in and I'm up and running. So...
HOW TO OPEN A SYNCMASTER 2053BW
NO SCREWS!!! Assuming that the stand mount has been pulled out..The seam around the screen frame is where you start. The frame has the prongs, the back cover has what the prongs slip over.The frame is coming off first! I got the side to open by finger, then used a small standard screwdriver to pry ever so gently(lifting frame from rearcover). Leave the power button assembly on the frame, pull wire only a little to relax any tension..you get about 3/4" in extra taped to panel. The hard part is done.;) Still holding the frame...Now lift the panel (where the power button assembly wiring goes under panel) with the power housing that is under it as a whole and you will see where the powerbuttonassemble detaches.Remove frame. Now..holding edges of panel into back cover, lift and flip the whole thing over and place panel face down on a perfectly flat surface..a towel on my desk works. Lift and remove back cover.Your now looking at the back of the board housing. The ribon is simple, on the panel end of the ribon, squeez the outer clips together and slide it away against the panel..The secondary tin plate is removable, two clips super close to where the sets of wires come around the housing and into the panel.Unhook the 4 plugs(pink inside/blue outside)...Now lift the power housing off of the panel. The big board has the power. One screw to remove a ground plate first. Two screws to remove power board.

Reassemble but DO NOT re-snap the frame into place....yet... Test it! There is a reason the caps got hot in the first place, therfore it has a good chance of happening again. This is not fullproof...but.....mine has been on now for close to 6 hours with no glitches whatsoever. So I have resnapped mine back together. I hope you can too. - I must also add that this is one of the best producing monitors I have ever seen...in 60hz. The clarity is top notch. If you purchase one get the extended warranty. FYI...I paid $4.00 for those caps.

The Power LED Is Blinking But No images Appear On The Screen.
If the power LED on your LCD monitor is blinking and you have no images on the screen, either the monitor is in Power Saving mode, or you've inadvertently set your video card to a refresh rate and/or a resolution your monitor can't handle. Both problems are addressed below.
Power Saving Mode To get your monitor out of Power Saving mode, press a key on the keyboard to activate the monitor and restore the image to the screen. If there is still no image and your monitor has a Source button, press the Source button. Then, press any key on the keyboard again to activate the monitor and restore the image on the screen. If this does not work, go to the section on changing the refresh rate and/or resolution below.
Changing the Refresh Rate and/or Resolution The optimum refresh rate for all Samsung LCD monitors is 60 Hz. The optimum resolution varies according to monitor size. The chart below shows the optimum resolutions for Samsung monitors by size.
15 to 16 inches
17 to 19 inches
20 to 23 inches

I replace the Two Capacitors but now displays No signal when VGA cable is not connected and blacks out when I connect a input from laptop or TV tuner through VGA port, If I change the input resolution the screen turn in to strange Blue colors and some time displays blue screen totally, but picture wont come.
Can some body help how to fix this?

I have a Syncmaster 204B which had the same problem, I followed these instructions, and sure enough the same two caps were vented. I replaced them with new ones (using 1000 µF instead of 820 µF as it was all I could find and the guy at the electronics store told me that there was a wide tolerance. It is now working like new.
Thank you for the tip!

(Samsung SyncMaster 204B) Flashing Power Button
Im having the same problem. I go into work one day and the monitor is black and the blue power button just blinks consistantly. i can even hear the electrical frequency beating as well.
no settings were changed, no trauma was given.
ive taken the monitor home and hooked it up to my gaming PC which works fine. Set the Nvidia settings to dual monitor, it reconized the 904B yet it remains pictureless with the flashing light. only change made was it went from an Analog VGA connection to DVI. same issue.

When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.
But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Ultimately I had to return the monitor to Best Buy where I Originaly purchased it. Luckily I had purchased it between Thanksgiving and Christmas when the the store had a 1 yr exchange policy. They had to send it back to " have a card replaced" ( They're words). Took about 3wks to get it back no charge. Seems to work fine for now but who knows how long this will last. Will probably be my lasy Samsung
