Let's Fix my old Playstation Portable - R-Button not working (PSP 2000) 

I'm glad that my video helped you so far and I hope the rest of the repair goes well. Thanks for your comment! =)

Sure thing, but I ordered from a seller in Germany via ebay. This should be a fitting set of all the flex cables straight from China: www.ebay.de/itm/Direction-Cross-Button-Left-Key-Volume-Right-Keypad-Flex-Cable-for-PSP-2000/271882175925 It will take a while to get to you, but if you search for "PSP 2000 flex cable" on ebay, you might also find offers that ship from your country. You might need different cables if yours isn't a PSP 2000, though. Hope this helps. :)

If it's a similar issue and there is a broken connection in the ribbon cable on the left side* of the PSP, then replacing that ribbon cable should fix it. (I'm pretty sure that in most cases it will, but no guarantee!) *Just remember that the L-Trigger will be on the right side when you flip the PSP around. :D That's a stupid mistake I might make, so I thought I'd mention. ^^

I think that for sure mother board isn't the problem because its pressing two times and after that is dead.

"If it ain't broke, fix it 'til it is!" :D But yeah, learning from fucking up is part of the journey. Just don't give up! :)

@@RaykOscuro I just fix it! All in 5 minutes, after a lot of "practice"

@@Jose-mc5dl Glad to hear that it worked out in the end! I love the moment when you turn it on and finally everything works. :D

@@RaykOscuro I feel like a child again

Yes, it is! :) Probably the first screen protector I ever applied to anything, back then.

I haven't had this problem myself... if there's no sound at all, I doubt that it's a problem with the speakers themselves, but you could definitely check the connections. ifixit has some simple approaches listed on their site as well: de.ifixit.com/Wiki/PSP_1000_Troubleshooting#Section_No_sound_is_coming_out_of_the_speakers It's for the PSP1000, but I don't think it makes a difference in this case.

Oh no! I hope you get it all fixed. If you try to fix things, there's always the risk of causing more damage I'm afraid. I fixed the buttons on a PS4 controller once and broke off the really tiny LED. But I was actually able to solder it back on and I was quite proud of that. :D

Update: I fixed the lcd screen finally! I had a broken psp lying around which had a functioning lcd. I was excited at first until I realized that the menu bar at the bottom of the psp also didn’t function hehehe. I’ll try to fix it all tomorrow but for now a fixed r button and lcd will do.

...are you sure?

I did go shit on your moms chest clown
