I have an eMachines E15T3g monitor that is dead. The story is this:
A friend got this LCD from eBay with the AC input cut of from the cable (this monitors have the DC input socked attached to the end of the VGA cable just like some monitors have the audio cable). He opened it up, and soldered the plug back into the internal cables that he decided (yes , decided. Not traced, or discovered. DECIDED) were the DC input and after that, he plugged it in and boom : fuse blown instantly. He connected Vin and GND inverted, apparently, unless the ground signal is the one that is fused and then after the fuse goes directly to a (+) terminal of a 470uf 16v cap.
Well. Caps (Teapos) replaced, fuse reinstalled (he installed one new one and tried again. I installed the third and final fuse myself). There is DC input to some of the main board parts. I traced the voltage path up to the 1501-50 IC, where it is lost. I had another (dead) board from a Planar PT1500 that had that same chip, and tested it. While the one in the eMachines had the pins 3 (GND) & 5 (SD - shutdown/on) shorted (1 is V input), the one in the PT1500 did not. My problem is, how can you remove the IC in a way that it does not end up like the one in the 2nd picture,which was destroyed - literally - trying to be removed. I know that it looks like I tried to remove it with a fork and a knife, but I just applied some pressure on the bottom to try to lift it and ... well... see the pic
The third one is the full image of the board in question.
