VFC PEQ Box Problem

[Katana]

It keeps flickering constantly brighter and dimmer and on and off when activated. Moving the selector around and even pushing down on it seems to affect the flicker but no matter if it is the laser or light, it keeps doing it and it is very annoying. Anyone know any fixes?

Strip it and see if you can get into the contacts and selector. If you can spray some electronic contact cleaner in. It might fix it and it's probably a better bet than taking it to bits to resolder.

If it doesn't fix it then you know you have either bad solder or a poor selector.

With the contact cleaner do a test area first to make sure it's not going to melt the plastic.
