Re: Samsung syncmaster 205bw

Same problem...
Blue light all time, without any response on click any button and nothing displaying on the screen.
Caps are okay, not swollen. ¿What can I do?

Dixie, Behemot, juggernaut... Anyone that had the same issue, have you solved that?

Post good clear pictures of the front and back of your boards.

Use manage attachments and use jpgs less than 3mb

Re: Samsung syncmaster 205bw

So I'm having the same troubles, solid blue on the power light, no display or response to buttons. My computer does recognize it as a display when it's plugged in. I haven't switched out the capacitors, but I'm not seeing any bulging, and the earlier posts that say they switched and saw no change worry me. I've attached the pictures, any thoughts on a move forward is mighty appreciated. This is my first shot at fixing a monitor, hoping to get it working...

Can you see image with flashlight?

Lately the price of generic power supplies with inverters is dropping so there is a possibility of using universal board if the repair fails.

Can't see anything with a flashlight, nope.

Re: Samsung syncmaster 205bw

That's with display connected to computer and all set up right?

Re: Samsung syncmaster 205bw

Yep, fully reassembled and plugged in. Computer recognized two screens, nothing on the monitor with or without flashlight. Had a bit of a misstep forgetting to plug the display ribbon cable back in, thankfully noticed that the second time around

Re: Samsung syncmaster 205bw

If you still cannot see anything than possibly the signal board is bad as long as not only the backlight does not work but also there is no image at all.

Check that the PSU is supplying all the rails it should be, and they are correct. Check any regulators on the logic board and make sure they are working too
