Re: Samsung Syncmaster 225BW
Took it back apart, and no obvious connection problems. Yes, the connectors now have the voltage on them: 1 = .094vdc, 2-4 = 0vdc, 5-7 = 13.09vdc, and 8 = 12.98vdcLeave a comment:

Re: Samsung Syncmaster 225BW
Well, after reassembly I get the rapid flashing PWR LED, no back light...
Then after sitting for a bit, the PWR LED turns and stays solid.
After sitting powered on, I start getting some backlight flickering. Still no image though.
I'll tear it down and make sure I got everything together properly.Last edited by castellscl; 09-10-2015, 06:20 AM.Leave a comment:

Re: Samsung Syncmaster 225BW
Ok, yup, silly me. It does have the 167VDC there. I'll try reflowing the solder.
Ok, solder reflow worked, Now I have rapid flashing power LED... and slight clicking sound from "HOT" area on board.
Edit #3: Ok, Held power button for like 10 seconds, and seemed to turn on. Going to throw it back together and see if it works...Last edited by castellscl; 09-09-2015, 02:59 PM.Leave a comment:

Re: Samsung Syncmaster 225BW
Ok, I have a Rev. 0.1 board and had the same problem as everyone else. I replaced all 6 Caps with the ones listed in this thread.
Now I have NO POWER at all. No power LED or anything. I've checked TH101 and F101, all good. I have .04vAC across the leads of C105 (Big Cap). I put the old C107 back in to verify and same problem. Not sure of where to test next...Last edited by castellscl; 09-09-2015, 11:47 AM.Leave a comment:
