Re: Samsung Syncmaster 245B Black screen and blue Power LED
Just fixed mine by replacing RB805. Multimeter was not reading any value on that resistor. Other two were reading fine around 68ohms. So did not need to get to CM802 capacitor. Thanks to all who contributed to the thread.

Where did you source that special capacitor?...Leave a comment:

Can LCD panel be replaced
Hi all,
Just wondering can be LCD panel replaced with a panel that taken from different monitor but same size?
I can see its power plug is identically shaped and assume it takes +5V.
However I could not guess its data wire configuration. Old panel has a about 30 pin long parallel plug which about just 20 of them are accommodated with wire. And new panel's data plug is identically shaped to old but little short and has 20 pin wire.
Wire colours are completely different. So my confusion is here.
For further information I have attached data plug of old and new panel's...Last edited by bathuu; 07-28-2009, 02:24 AM. -
Re: Smasung SyncMaster 913N Monitor wouldnot display images
Well, my joy did not last long.
After having tested monitor for an hour, it failed to display images and start showing "Not Optimum Mode" symptoms. So I guess one problem seems to transferred to another. Hope this one has a way around it.
Cheers all. Any suggestions, what I should do now?Leave a comment:

Thanks for response Gonzo,
There was a post in DT Forum, which guy said he simply bridged 2 pins and his monitor has been going good for like several months. So this bridging would cause any damage to other parts of board in the long run? Or it won't be serious concern?

UNBELIEVABLE!!!!!!!!!
After just soldering pin 5 and 6 together, my monitor is back into life.
WOOOOOOOW.
Thanks for contribution all, Specially to Gonzo and Eguevarae.
But still curious to know what was the cause of such defect.
Cheers all. Everyone have a wonderful day.Leave a comment:

Thanks for reply, Eguevarae. I have attached a picture of inverter board that has DC output to the Logic board. Which wires do test? What value they should show?

Re: Smasung SyncMaster 913N Monitor wouldnot display images
Sorry, my bad. It is typo, I meant 713.
I'm newbie to electronics. Just don't know how to check voltages coming from inverter board. I have DMM, If you could enlighten me little bit. Which wires do I need to test? And on settings DMM should be set?
Next, I'm considering to solder 5,6 pin as advised Gonzo.
Cheers cheers, thanks for replyLeave a comment:

Thanks for reply guys,
I follow up your advise and see what I can do.
To eguevarae: I could not locate any small cap labelled as 712 on my inverter board. Possibly, my board design is different than yours? Here I attached picture of inverter and logic board.

Smasung SyncMaster 913N Monitor wouldnot display images
Hi all,
First of all, I have to say that it's great forum that has many valuable posts from experienced people.
And my problem is I have Samsung SyncMaster 913N 19' monitor that has dull black screen problem. When it is not plugged to computer it displays "Check Signal Cable" message clearly. So i don't think it is power inverter problem. To ensure that I opened back and checked inverter board all caps seem in good state, no bulge or any suspicious component.
But once hooked up to computer, it would turn to black screen, and power green...Last edited by bathuu; 07-16-2009, 11:19 PM.
