HOW ABOUT SOME CAMCORDER TECH TIPS…ALL I REPAIR ARE CAMCORDERS AND IT WOULD BE VERY HELPFUL IF YOU CAN SUPPLY OR SUPPORT CAMCORDER SERVICE. THE MFG. DON’T WANT TO HELP EVEN THOUGH WE HAVE BEEN REPAIRING VIDEO CAMERAS AND CAMCORDERS SINCE 1984…SONY, JVC, CANON ARE MY MAIN INTEREST IN SERVICE. THEY QUITE THE TECHNICAL ASSISTANCE DEPARTMENTS BUT STILL WANT US TO SERVICE THEIR CAMCORDERS. PRETTY SOON, THEY WILL STOP SELLING PARTS AND TELL EVERYONE TO FORGET THE BUSINESS.
This is great feedback, Manuel, and we will see what we can do to assist. Thanks for taking the time!
