Psp Broken!!

My psp is broken, as the title says. when i go into the vsh menu and i press exit, i cant press any buttons on my psp. also when im in game my start button doesnt work, and the other day i was playing it and the game i was playing kept going into sleep mode like every 2 seconds. ive tried installing a new firmware, it installed fine but im still having the same problems.

I cant see me fixing this and i think my psp is dead for good :(

Well that's a strange one, perhaps it's a hardware issue. Maybe some parts are wearing out and needs replacement?

I found out what the problem is, my button bar is damaged. I would like to use a program such as macro fire to remap and disable the buttons not working. although im finding it very hard to configure macrofire because my start button is being constantly pressed. can anyone please help me with macrofire?
