wondering if someone could help me, I have an 8" Lilliput lcd screen, (the new ones i guess, since it has the snap-in connector instead of the old usb one) well anyway I received the monitor byitself with no cables or anything from my friend who wants me to get the replacement cables for it, he went on a trip and lost the bag that had the cables in it. I took it home and hooked it up to a universal DC adapter, set the voltage at 12V and think I may have fried something, I didnt set the polarity since I did not know which setting it needed, but nonetheless it was plugged in for about 15 seconds and pushing the power button did nothing, but after about 10 seconds I heard a "sizzling" sound, like some kind of liquid was boiling or something, I immediately unhooked the power from the unit, but noticed a strong smell of what I was at first puzzled by, but remembered I had used something earlier that smelled just like it, finally it came to me, it smelled like Noxon 7, the metal polisher and cleaner (comes in a green bottle and is great for cleaning up metal but anyway...). I'd say this is the only thing I could describe it as, it was very pungent and strong, so I dont know if I fried the unit, or maybe I just fried a fuse/diode inside (hopefully) that was there in case something like this happened and maybe
I could replace it myself and get it working again, any help would be much appreciated, I would feel really bad giving my friend back a non working lcd when he trusted me enough to try and help him. Thank you again, feel free to contact me at detonatorz@aol.com I check my email several times a day.

did you reverse polarity and try again? If it's fried, it's very likely VERY fried and won't hurt to see if it still works. But it sounds like toast. That is, the inverter for the backlight might be toast. I hav seen several LCD displays with seriously burnt backlight power supplies that still worked fine, besides not having any backlighting (read: no image display)
In the future, either verify polarity FIRST, or else do the testing FAST. I'm a little surprised at your result because when I hooked up power to a couple of my displays backwards, they sent out unhappy sparks and noises immediately (and worked with the power set straight).
Turn on the power supply before connecting it might be a third suggestion for the future.

Fixed it!
Hey everyone just figured I'd post that I was able to fix it by replacing a simple fuse inside, if you need to know how feel free to contact me, peace and G-d bless.
