What kind of business would fix a video mixer?

Question

It blinks and I've tried sound shops, and a technology place from the yellow pages. They have no clue as to who might work on them.

Answer 1

Try calling the company that made the mixer.  They should know where you can get it repaired.

Answer 2

if it is a professional item, the local TV station should know how to contact factory service.They might also know if there is a local contract engineer that could repair it.

if it is a consumer item, then it might be more expensive to repair than to replace with a new one.

i purchased a Panasonic WJ-MX- AVE5 when they first came out, and when it needed a repair, Panasonic bounced it between the Consumer Division and the Broadcast Division several times.  Eventually the consumer side fixed it even though it has a broadcast  model number. Fortunately in was still in warranty. Since that, i maintained it myself (i am a broadcast engineer) not trusting the consumer people to know how to align it properly.
