Re: Samsung Syncmaster 223BW - dead as a rock

Hello

I attached the service manual, maybe you'll find something to troubleshoot your problem.

But, first:
1. Check the LVDS cable or change it.
2. Check LVDS connectors for cold soldering or bad connection (both digital board and panel).
3. Check the 3.3V pinout on the LVDS cable.
4. Follow the steps described in the service manual....

Re: Samsung Syncmaster 223BW - blank screen..

Hello guys.

Has anyone troubleshoot the logic board?

All I'm going to write is just what I read online, nothing is tested.

Reading different forums, I saw that most of the techs (including me) are trying to find a faulty electronic component. Nothing bad till now, but not all to accomplish the final job.

Reading some polish/russian forums (using google translate), I realized that I overlooked the bios (firmware) role. Itself, the firmware might be responsible for this kind...

Re: Samsung Syncmaster 223BW - dead as a rock

Hello guys.

Does anyone figured out what's wrong with the logic board?
I had to recap the main PSU and after that the LCD is still "dead as a rock".
I measured all the voltage regulators 1.8V, 3.3V and 5V and they work fine.
But the 5V at the LVDS connector is still missing.

Any ideas or suggestions??
