Samsung syncmaster 275t won't start - what to do?

Samsung syncmaster 275t won't start, I have it working fine during some years now but in 2010 Nov.I had to unplug and store it until some issues where solved (not related to the monitor anyway).Now I'm trying to use with my notebook (Acer) with ATI RADEON HD4330 latest driver and window 7 64-bits. This is the third day I tried and won't work. Details: I brought an adapter with a female DVI and a MALE VGA to connect with the notebook and all is normal to look but the display on the Samsung Sync-master 275t continues to flash the blue light in the start button and won't stable, only flashing on and out. I try to push the 'auto' button and nothing the 'source' button and displays the 'digital' label. I disconnects from the notebook and shows the blue and white label/Trade mark from Samsung flying around the display with a note saying: Check signal cable: DIGITAL What do I do? To fix such issue? thanks CG

    well I did try to use ONLY the digital monitor the extra one, but the monitor of the Notebook has no option to turn it off and use only the digital(extra one) it's a Radeon 4330 - 512 MB which gives no possibility for it. So I'm stuck with the problem...
    Can't figure how will try the samsung syncmaster 275t in other notebook, since I'm in a foreign country where I don't know anyone to ask for a test ...
    Any clues besides a test with another computer?
    Thanks

The Samsung monitor is okay, the problem is a compatability issue between the laptop and monitor. The VGA toDVI is the problem you are converting a analog signal to digital, the signal level degrades when that is attempted. If I understand this the laptop puts out the analog signal "VGA" and the monitor has the DVI input, "digital" The only other suggestion is turn off the laptop screen to see if the monitor will work.

    If you are near a computer repair shop they may have a used VGA monitor at a cheap price, which would solve your problem.

SOURCE: Have A Samsung 940Bw connected via DVI connection

First thing I would try will beusing this monitor with another PC using the same the same setup to see if it works OK. We need to narrow down the cause of the problem first since you have three parts that can be bad; Monitor, DVI cable, PC Video card/PC. It is just a process of elimination to locate the problem.

Screen turns on for a second then flashes off. Just saw a post that said this could be a capacitor problem. The Monitor is the 225bw not the 275t

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitorswillblow a power supply. The problem is caused by parts called capacitorsoverheating in the confined space of the monitor. If you are good 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 fine.You should find 5 bad capacitors. If you can take a picture or two of your board and email them to me I can tell you what to replace. The capacitors do need to be installed with the correct + and- connections, note the stripe on the old one and insert the new onethe same 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.
