Home button issue....Need help

[KrInEn]

Ok I posed about this a while ago and have limited it down to the home button. When I go into a emulator or into the music section my screen bounces back and forth between "Do you want to exit" or in the music it bounces between the currently playing song and the list of songs.
I have replaced the home bar that worked for all of two days. I cant figure it out. It does not do it with the faceplate on of course  but nothing else is hitting. No other button like and of the volume keys argh!!

Update, Still does it with out the home bar, LCD, or LCD cage in place  Now I'm really confused. Bah off to watch Enter the Dragon. Maybe Bruce will have some answers for me LOL. or maybe by the time I get back there will be an answer

    It sounds to me like two possible things can be the problem. One , is this an aftermarket faceplate? and two, what kind of home bar set of buttons do have on your psp. Alot of the times, aftermarket faceplates tend to have a thick coat of paint around the button holes causing the buttons to really stick. A similar scenario applies to aftermarket button sets. In this case, gently scrape off a bit of the paint from the faceplate, enlarging the hole diameters. Good Luck....

it may be because of the screw behind it try fiddling with that

I have taken the thing down to the mobo and it still does it. I am thinking that there is a short somewhere. im just going to wrap the damn board in insulating tape LOL that will fix it/burn it out :P

lol. try taking out the whole mobo out of the case and then powering it up. if there was a short it would be gone.
