My trusty 10 year old Mitsubishi Diamond Pro 920 loses its red gun periodically, giving a blue tint. A healthy slap on the casing sometimes fixes it. Could it be a failing solder joint, or is it the electron gun failing do you think? It's not the cable connectors. I opened it up and cleaned out the dust, and worked all the connectors I could remove to clean the contacts.
