Re: Toshiba Satellite - Locks up when plugged in
That would be for OE128, right? What about OE907, same?...

Re: Samsung Syncmaster 920n white screen
At [url]http://www.sharefx.net/monitor-repair/hannstar-lcd-panel-hsd190me12-a10/[/url] I found this info:
This sounds reasonable. These are around EL7581 chip, and according to spec here:
That should be Schottky diode MBRM120LT3 (20V 1A). Would MBRM120ET1 be a compatible diode (which I can find on Ebay)?Re: Samsung Syncmaster 920n white sc...d EL7581 chip,Leave a comment:

Re: Samsung Syncmaster 920n white screen
So D100 does look burned. Also, it shows about 1.5 in both directions. This is a HSD190ME12-A11 panel. Any ideas about a replacement?Leave a comment:

Re: Samsung Syncmaster 920n white screen
I just noticed my mistake myself
It is indeed marked D100. My multimeter has diode test mode and it shows values of around 1.000-1.050 (are those V?) in both directions. Does that mean its busted?
Fuse F200 measures less than 1 ohm, that means it works?Leave a comment:

Re: Samsung Syncmaster 920n white screen
Yes, white screen was before and after. Also, same when I disconnect long panel control board. On it, there is one named F200 (as far I see, only one marked with Fxxx there). How to safely check if it is the culprit (it does not look busted)? What specification fuse do I replace it with? No need to look too professional, I might solder an external one.
Also, there is an element R209 that looks like it could be busted - but not too much.Leave a comment:

Samsung Syncmaster 920n white screen
Hello
I have this Samsung Syncmaster 920n who powers on, but only backlight - screen is white and there is no image. I've recapped the PSU, replaced 2x 820/25 1x 330/25 using new decent caps - no luck. I've also read here that some similar models need replacing a fuse which I just can't find. Anyway, here's a picture, any ideas? Better resolution on request.
Btw this is for my old mother, have heart :o...
