Re: NForce 680i SLI Bad Caps 122ck-NF68-B1

Just to close out this thread, I replaced the caps and the motherboard is now living again. Thanks to everyone for their help.

Re: Samsung 245BW - Power Board BN44-00195A - No display, solid blue light.

Sorry I haven't followed up on this post. I put the monitor aside for awhile while working on other projects. As suggested in other posts, I cleaned the brown goop off of all the components on the board. That crap must have been very corrosive as many of the components show significant affects from it. I put the monitor back together and it still exhibits the same problems, solid blue power light, black screen.

I did find a service manual with schematics on another post. I will see if I can...

Re: Samsung 245BW - Power Board BN44-00195A - No display, solid blue light.

Thanks for all the good information. I like the tool. I measured the resistors. One measured 89K, the other measured 46K. Seem to be out of spec. I'll be removing the glues and see if I can get it to fire up.

Re: Samsung 245BW - Power Board BN44-00195A - No display, solid blue light.

I took another picture of the affected area of the board. I checked both resistors. They are open. I'm trying to get new ones but the color coding on the resistor is confusing me. I'm reading the colors as gold-yellow-black brown. Gold as the first bar isn't making any sense to me. Comments would be appreciated....

Re: Samsung 245BW - Power Board BN44-00195A - No display, solid blue light.

Thank you for the replys. I did read the megathread and saw the mention of the cluster of 68 ohm resistors on the bottom of the board that go bad. However, I thought that referenced the BN-00173A board, not the BN-00195A board I have. As you can see by the picture, the 195A has a cluster of 2 by the large capacitor. Sorry about the picture, it is the best I could do with the equipment I have.

I've been reading all the threads on this power board. Apparently, my monitor has same problem as others, no display, solid blue light. There is a lot of discussion on the BN44-00175A about bad resistors being the problem, caused by the brown goop they use to glue them in place on the board becoming conductive. I haven't tested any of the capacitors or resistors yet but I suspect the resistors in the attached photo may be the problem as the brown goop between them shows signs of some arcing. Can anyone tell me the value of these resistors? The brown goop has covered up the markings on them as...

Re: NForce 680i SLI Bad Caps 122ck-NF68-B1

Thanks everyone for your help. I'll throw a couple 1800uf 16v 10x25's quality low ESR caps in and see what happens! They are definately tall 10 mm caps. Putting somrthing that big and tall that close to the corner of the board is just begging for them to get abused.

I'm working on replacing some bad caps on this motherboard. Much to my surprise, someone actually pulled a couple of the bad caps off the motherboard before I got to it. Does anyone have one of these boards so they can tell me the specs on the caps in the attached picture. Need size, voltage, capacitence. Thanks....

Re: WestingHouse L2210NW w/ DAC-19M020 power board caps

I found this manual on a Chinese website and answered my own question. Apparently it is a 35v 33uf 5x11 cap made by Man Yue, Rubycon or Nippon Chemi-con. I hope someone else can make use of it....

I've got a dead power board from a Westinghouse L2210NW monitor that has a DAC-19M020 power board. I am trying to identify the voltage and capacitance of the capacitor circled on the board in the attached picture. Unfortunately it is dead so I can't measure it and the silicone they used to secure it to the board has eaten away the capacitor ID information printed on the side. I believe tha capacitor ID on the board is CE101 but that is hard to read as well. Any help would be appreciated....
