Samsung 173P Monitor Went Black; Can't Locate Capacitors (Link to Photos)

Hi,

I have a Samsung SyncMaster 173P. It was great until it suddenly went black. It is not the computer. I tried another monitor on it, and that monitor works fine. The monitor's power light turns blue for about 4 seconds and then it's light goes out. The lcd screen remains black the entire time--not even a flicker.

I did some research and noticed many discussions about bad capacitors, especially on Samsung monitors. However, I found no discussions on this specific model. Nevertheless, I opened it up to see if I could locate any bad capacitors.

This monitor is different than any other one I have encountered (mind you, I don't have a lot of experience). The power supply and computer cable plug into the base. There are no cards in the base. Wires run up the support arm to the LCD screen. I opened it up and found 3 cards (see the photos of the inside). One is covered by a thin metal sheet (top of photo 3). The other two cards are exposed (denoted by a blue and red screwdriver pointing at them in the photos). The one on the right (with the blue screwdriver) appears to have capacitors but not ones with which I am familiar. In any event, none of them are bulged. The one on the left does not appear to have any capacitors. This is not what I expected things to look like inside. (Again, I am a novice but I have seen the inside of many monitors before.)

What should I be looking for? Could the problem be a capacitor that I have not recognized as a capacitor? Could the problem be something else? Any suggestions on how to proceed?

I considered taking it to a repair shop, but there are not any near me. I live in a semi-rural area. Any help would be greatly appreciated. I love the monitor and cannot bare the thought of discarding it if it can be saved.

  1. The link to the photos did not seem to take. Here is a link: http://www.flickr.com/photos/82972286@N06/with/9037602429/
  2. Your monitor clearly has an external power supply so there will be nothing to replace. The caps that would go bad in a monitor that could be easily replace would be part of the PSU board, which you do not have.
  3. Any idea what could have caused this or how to figure out what went wrong?

    Thanks. That helps clarify my situation. I replaced my external power supply with a universal one I have and that I know works. I had the same problem. So, the issue is not with the monitor's power supply. Any idea what could be wrong? I called Samsung and was told to send it in for service. However, between the cost of the service ($80) and the shipping cost (at least $50), I do not see the value in it for a 9 year old monitor.
