First, hello everybody. I've got a bit of a problem and I think someone here might be able to point me in the right direction.
So I bought a 3M 9800 OHP and a Samsung 152N LCD monitor. I stripped the monitor only to find that this line of monitor does have FCC issues. so i disconnected the FCC cable to remove the backlight assembly, which allwed me to then put the LCD panel on top of the OHP.
(BEFORE REMOVAL OF BACKLIGHT)
I reconnected the FCC cable as best i could to test the panel before the FCC extention comes in from Lumen Labs. here comes the odd part.
(FCC RECONNECTED)
When connected to a signal source (monitor 2 on my Radeon 9700) at any resolution, the small power LED blinks on and off at intervals, and the screen is blank. It does not say "no signal" as it should if it was actually not receiving any information. When disconnected from the signal, the screen gets many quick moving blue horizontal lines instead of the "no signal" that it should have, which change if I jiggle the FCC cable.
(ALL HOOKED UP)
I've checked the ribbons that go from the small boards to the panel itself, all seem to be intact. All of the other wires are connected as they should be, save the 4 connectors that run the backlight assembly. I'm wondering: is the FCC connected badly, and if so... how have you hooked yours up tightly? Or is it somehting much worse than a simple misalignment of the FCC?
Thank you for your reply.

An externally hosted image should be here but it was not working when we last tested it.

What happened to the white lock-down piece of the FFC connector? If you could snap that back on it would fix your alignment and connection problems.
Apparently, as I was gone at class, my wonderful cat decided to flip the backlight assembly off ot the table at a fast velocity. (I was keeping all small bits like those tiny screws and stuff on top)
I found most of the screws later, but alas, that white bit was nowhere to be seen. So, I made do with some scotch tape. It fit better than either masking or black electricians' tape, so i went with it.
I would have liked to have that piece though... would a place like mouser stock one, because that would be sweet.

Mouser would stock the whole FFC connector, probably. You could buy a new connector, snap off the white piece and put it on your connector. It'll take a little looking in thier online catalog, but it couldn't cost more than 5 bucks.
Sorry about the slow reply. (Was out in Colorado for a week)
When I arrived home, the extender and clip from lumen labs had arrived. so I connected the two FFC's together with the supplied clip. they fit tigether snugly, and that was pleasing.
However, when I attempted to insert the other end of the lumen labs FFC into the port on the monitor circuit board, it seemd a bit large. while it dosen't seem to be a large difference, I would hate to shave down the sides and somehow damage or otherwise short the connections. Would you recommend shaving a little off the sides in order to make the cable fit.. or use some other method?
Thanks
