I've noticed a few independent posts in the past in regards to repairs and upgrades of old figures so maybe this could be a starting thread (if people remember to use it )

Suggestions for various problems from a number of experienced people is always helpful.

Ok here's my problem;

Finally got me a G1 Blaster today in very good nick...except the buttons are screwed. I think these can be re-adjusted by the look of things. The far right button is permanently pressed down.

Surely there's been work done to fix this common problem.

Little help?
