D-pad not working properly with the game Zipang (mostly)

[Bekic]

It's a game in the same style as Solomon's Key, building and destroying blocks etc. You jump by pressing up but the thing is it happens unintentionally when i push the arrow to go left aswell. Not right. I press the button the same way when i want to go in that direction without any problems.

It's really fucking annoying because i'm barely putting any pressure. I can't play this fucking with this shit going simultanioniously so what should i do?

sounds like sticky rubber membrane, open it up and use isopropol alcohol to clean it, should work a charm ( I have opened every single used joypad to  reconditioned them, apart from dual shock 3 as it's complex)
