To anyone that has replaced their motherboard, or knows a bit about the inside of a PSP, I had a few questions.. First, here's my story. My black PSP ended up being bricked thanks to CINTRO, I flashed it.. It was my mistake, I should have checked the forums more throughly before installing that. Later, I learned they had a memory stick mod for CINTRO. In anycase, the deal here is my PSP bricked thanks to CINTRO. A friend of mine has a PSP that he doesn't use anymore, he opened it and god knows what he did. It looks completely fine, but now when I checked it, seems like the PSP Internal Power Connector doesn't work anymore, I put my old PSP battery in and even plugged it to an outlet and not even the orange light shows up. He says problems started occurring whenever his PSP fell, after that happened, if he were to insert a memory stick into the PSP somehow automatically shut off, so he decided to open it up and check the problem. He ended up messing it up even more though, he said that later he couldn't even get the screen to show up anything it just stayed black, and now apparently the Internal Connector doesn't receive power. To sum it off, the PSP had two heavy problems. - Screen won't show anything - Inserting a memory stick causes the PSP to shut off. So it has two problems now, but I know for a fact that this motherboard is almost identical to mine since he bought it around the same date. I ended up deciding to swap the motherboard regardless of the problem, upon taking the LCD screen off, I found the motherboard to look fine, nothing was loose. I took my own PSP apart and swapped the motherboards, I double checked all the cables to see if everything was connected. I connected the LCD Screen, and turned the PSP on. The problem is that I can see the green light, and unlike the bricked motherboard from my other PSP, on this PSP the light doesn't shut off by itself, I can push the power button up, wait a few seconds and it turns off by itself like a normal working PSP. On my bricked PSPs mobo, this wouldn't work, and it would automatically shut by itself after a few seconds, normal symptoms of a bricked PSP. I tried both LCDs, my friends and mine. Neither seem to work, I can only see the backlight and thats about it, no sound, no image. Could the mobo itself have another problem? I've also inserted a UMD and it sounded like it was reading the disk. dunno if that has any relevance. I put the PSP back together, and checked to see wether or not my memory stick would blink as if it were reading. However, it does not. I'm pretty sure its not the actual memory stick reader that is under the motherboard itself, since all I did was swap the MOBO, and I know none of my PSP parts had problems prior to the brick. My question are, 1) Do any of those problems I mentioned earlier rely on the motherboard itself? I want to swap the motherboard, that's it. 2) Do I need the exact same motherboard or does a different model number work? My MOBO is a TA-081 while the one I swapped with was a TA-079. Thanks in advance guys, I could really use the help. Sorry for the terribly long post.
