Hey guys, last night I couldn't sleep, so started piecing back my panel to put in its frame to see an image today or tomorrow, but I can't seem to get it fired up. (Eizo L365 15") There is no visible change at all in panel with or without signal. The menu should at least come up.

I see no visible damage to any of the FFC's. The LED lights up on the control strip, so power is making it from the psu board to the driver board to the control strip ... a good sign.

Two questions. Could it be a grounding issue? I tried grounding the driver board to the psu board, but that didn't help. I tried removing the panel from the shell I had it in just in case something was shorting the panel. I did not have the backlighting board driver plugged in, but I didn't think that would be necessary. I will try that this evening after work.

I have the feeling I am missing something obvious. Anyone? I think my PLOG has pics.

Hmm I might have thought through an answer. The two signal cables from the driver board to the edge connector boards to a backflip. I went back and reviewed my old pics (and put them on the plog). It could be that I didn't account for this in how I wired them back. We shall see this evening. The pics also show all the boards as being grounded.

Nevermind. I found the culprit. A capacitor on the driver board actually RIPPED off the PCB. I nearly wet myself. But, Murphy was kind, and I was able to bend it back down, make contact, TAPE it, and it works. I would attempt a resolder, etc., but at this point, I don't want to do more harm.

Sadly, in the ensuing struggle of plugging everything in, my workday monitor received a sizeable gash in the antiglare. sad.gif Luckily, it is down low and not readily seen. Looks like a cat hair. heh

if you are good with soldering gun find one with a fine tip and 10-15 Watts of power and solder a wire (one of those found in ribbon wires) at L3 side where joins with that capacitor and at the other side of the panel where the via (that hole that you see ) has a solderable contact.(find it using a multimeter).

But if you are not good and if turning on the lcd there are no changes leave all as it is.That cap together with the L3 should be a supply filter,it is better to have the cap soldered as it filters any unwanted ripple but if the supply is very stable than you can do without it.

thinking twice you should try to solder it as i don't know where it goes on the other side but it should supply something,try to see where that hole (via) at the left of the cap goes on the other side.

I totally agree about the soldering, but I have attempted to make the circuit work first prior to using my less than perfect solder skills on it. smile.gif I have done well in the past, but there are not many more gut wrenching project moments for me than placing hot iron to expensive shoddily built pcb. heh

I have some pics of my triage fix in my plog (in signature).
