Re: Samsung Syncmaster 245BW
Nevermind. After I took the inverter photo, I examined the plug from the power supply to try to figure out which lines to test and noticed the plug slightly askew. I clicked it into place and the monitor works.
The resister -- $1.19 for five at Radio Shack -- was the only problem.
Thanks to you both for your help.

Re: Samsung Syncmaster 245BW
I've attached the inverter board photo. How do I perform these tests?
From another thread I know that the inverter board fuse is the small white rectangle just left of the plug from the power supply. The other fuses are on the power supply in a previous photo....Leave a comment:

I replaced the bad resistor and it now passes the flashlight test but no backlighting.Leave a comment:

Re: Samsung Syncmaster 245BW
How do I specify the part? Just ask for a 68 ohm resistor?Leave a comment:

Re: Samsung Syncmaster 245BW
Good call. 805 reads 400k. The others read 67 or 68.Leave a comment:

Re: Samsung Syncmaster 245BW
As I mentioned in the original post, the power on LED does turn on when the monitor is turned on.
You'll see two white fuses side by side in the upper left corner of the front side photo. Unfortunately they aren't transparent and thus can't determine by looking whether they are defective.
Hopefully the photos are adequate. My digital SLR got doused by a wave and died. These were shot with the 8 megapixel camera on my phone at the highest quality setting....Last edited by trossi; 07-30-2011, 05:30 PM.Leave a comment:

Samsung Syncmaster 245BW
I have what seems a common problem. I have no picture at all but the power LED lights. The failure was sudden. The monitor worked perfectly then the next time I powered it on, I had no picture. Pushing the menu button has no visible effect. I connected it to a second computer to confirm that it was the monitor and not the PC.
I assume the inverter has failed but don't know how to test that hypothesis. I have disassembled the monitor and did not see any bulging capacitors.
Can anyone suggest next steps? I have a multimeter but am inexperienced in its use. If you suggest... -
