Re: Smasung SyncMaster 913N Monitor wouldnot display images

Here is a photo of the back of the board. The dark stuff surrounding the solder points is rosin flux from my desoldering braid. I didn't clean it from around the contacts, but I did clean it from the contacts using a q-tip before soldering the new caps into the board....

I will charge the battery on my camera and post a pic as soon as I can.

Re: Smasung SyncMaster 913N Monitor wouldnot display images

My case mod inverter did not have the right connector to allow the ccfl's to plug into it. I completely disassembled the LCD and visually examined the bulbs, they are noticeably blackened at one end, does this mean they have burned out?

Re: Smasung SyncMaster 913N Monitor wouldnot display images

Thanks PlainBill, I'm glad I haven't tried checking them yet. I have a black-light system in my computer case; I have heard that you can use them to check ccfl's. I don't want to blow up my lights, but I would like to rule out whether it is the bulbs or the inverter board.



The above is true, if I turn off all the lights in the room at night I cannot see anything on the screen. But if I turn on the light, and look at the screen at an angle I can see the pictures on the screen.

Thanks for your reply Daniel...I have replaced all of the caps on the board except for the "big boy" and only get the dim picture. I performed the voltage check on the board as described earlier in this post and the voltages are normal: The big cap is running 165v (us) and the smaller ones are steady at 13v. I also checked the fuse on the board, and it is good. I didn't check output voltage to the ccfl's, is there a certain way I should do this, anyone?

Re: Smasung SyncMaster 913N Monitor wouldnot display images

I have a syncmaster 203B, will this testing method work on it? I have been troubleshooting and trying to repair this monitor with no luck. I have replaced all caps except for "big boy" but still can't get it to work. I don't have any board to interchange with either.

All I can get it to do is the Dimly lit picture. When I got my hands on the monitor, it would not power on at all, just blinking led. After replacing the blown caps, and the ones that showed no visible damage, the monitor will "power...

Re: k8ngm2/ms-7207 v1.0 - Wrong caps?

Ooops, the additional caps that I ordered for this board were 1500uF 16v 105C. My bad...... I was repairing an IMac G5 at the same time and the 1000uF were for it. The IMac was a success btw, I'm proud of that one! lol

Re: k8ngm2/ms-7207 v1.0 - Wrong caps?

I am having this problem as well...the computer will not POST and there is no video display. The fans run, drives come on, LEDs are lit.

I haven't tried the baking trick, and probably won't as this is not my machine, it has been brought to me by a friend for repair. Anyways, on opening the case I noticed that the caps running along side the CPU were blown. So, I took an extra board that I had (it was working) and pulled the 3600uF 6.3v caps off it and replaced the bad ones. This made no difference.

At this point...
