Can you crack a screen like this??

[Th3_uN1Qu3]

I'd picked up a 15" LCD for $15 a while back. It was the type with external power brick, it has absolutely no power supply on board, so it needs both 5v and 12v. The seller turned out to be a store clerk at one of the electronics stores i visit regularly.

When i got on the subway (where there was good lighting) i immediately noticed a number of black blotches. Cracked screen. He agreed to give me my money back, i ended up dropping by at his work with it. Today i went to that store to buy some 18awg copper wire for winding inductors. It turns out he kept the monitor there, and he found someone who wanted the electronics. Probably $5 is better than having an useless monitor around... So he asked me if i could take it and wire a power connector to it, so he can show that guy that it lights up then drop by again when i have time and he'll buy me a beer. Oh alright...

The retention tab on one of the LCD ribbons was missing so i never bothered to even power it up first time around, i was convinced it was cracked anyway. I stole a tab from a junked dvdrom, fitted it to the panel, that secured the cable nicely. I soldered a molex to it and plugged it into a PC power supply. It lit up alright... but it looks even weirder than i'd imagined with the screen off. I've never seen a screen like this - i think i couldn't crack one in this style even if i tried. What's funny is that unlike a typical screen crack, the blotches will not expand further if i press on them.

Take a look...

Pressure cracks from the casing, maybe? Could also have frozen. I'll have to get a picture of my old 17" that I still use as a secondary monitor. It's cracked around the entire outside of the panel.

I couldn't see it being from the casing. From something put on top of it, maybe. He said he had a lot of 15 of those and this was the last one, who knows how they were carried.

Could also have frozen.

That's an interesting theory, but not viable at this time of the year.

You know what's funny? Under the black spots you can actually see the picture. Edit: I'm going to give it back now and get my beer, i used it in portrait mode as a second monitor for a short while. Now i realize i really do miss having a second monitor...

I have an old Pixo AT500-s that has a similar blotch near the center of the screen. It started as a stuck green and blue pixel. It's now .75" in diameter, it's a shame cause it had a good picture. This display was bought new in '05 and never been dropped or exposed to freezing temperatures. I'm guessing it's a manufacturing defect in the panel itself. Not worth fixing unless I can find one with bad p/s or logic boards. The power supply on my model is internal to the display. There are models like yours, unique, where it's and external 'brick'.

This one had crappy viewing angles anyway.
