Sony MSX2+ HitBit HB F1XDJ Keyboard Issue

Greetings everyone,

I recently bought a Sony MSX2+ HitBit. The downward arrow of the keyboard only works if I press it down really hard. I opened it, cleaned the membrane, although it was already looking good. But it still behaves the same. Any suggestions? I also contacted Paulo Maluf for a new membrane, but doesn't look like he will be making new ones anytime soon.

Thanks,
Regards,

Gorlock

Hi Gorlock Smile

Look if the terminal point (circle) of the keyboard is not damaged and check the spring just below that key, is very likely to be a problem with the spring, but check the terminal circle, if the terminal has scratches or lacks part of the "ink" yo have to repaint it with a circuit repairer or use graphite as temporary emergency solution

Kind Regards Wink

Hi DrWh0,

Thank you for your reply. The spring is working fine. And the membrane doesn't look bad. Here are some pictures. On the second one, I marked where the terminals are. Please let me know what your thoughts are after examining these images.

Thanks again,
Kind regards,
Gorlock
