I was given this Acer X193w as "dead".
Indeed, first time I tested it, I got a 2 seconds to black issue (repeated 2 times) with some buzzing noise. Probably a bad CCFL/connection.
I took it apart and first thing I observed is that I wasn't the first one in there.
I noticed that the LVDS FFC had been messed with too, and in fact it was broken at the end of the motherboard's side connector. I removed it from the connector, cut the end of it, sanded the "new" end, cleaned it up and plugged it back in. I made sure every pin was making contact from the panel's side connector (this end is good) to the motherboard's connector pins.
After playing with the CCFL connectors, I got it to stay on for more than a couple of seconds, even though the noise was still there and the backlight was flickering.
I connected it to the computer and… everything was staying black, even though I had a faint backlight.
Well, I guess the broken cable did damage something else. I tried the panel on another display and it works ok (without backlight though).
I'm going to first replace the cable with a new one, then I'll go for the mainboard. And if I manage to get an image, I'll try to disassemble the panel to fix the backlight.
