I connected my 7" lcd with reverse polarity (3S Lipo). Lcd is this on http://www.dealextreme.com/p/portabl...40x234px-81058
Reverse connection was max. for a second cause I heard some cracking... so disconnected. Connected again with correct polarity- lcd came on but went out after a few seconds... smelling fried electronics. Disconnected immidiately.
Would be cool if this could be repaired cause its a really nice lcd... shows static without bluescreen.
Here are some pics of the PCB
The backside shows no burns or anything - also no components on the back.
Looks like the only thing burned it this black chip.
What part might that be exactly? Voltage reg.?
cleaned up with alcohol:
