I have an old Harman Kardon Receiver that I was sure needed a major fix. I called Ariel and he said he wasn't expert on it but for $30 he would stop over and take a look at it as often times it is in the settings and if he couldn't fix it there he would recommend a shop in Phoenix that could fix it more quickly than he could.
Well, Ariel stopped by and checked the connections and the settings on my TV and DVD player and with some resetting - guess what, it works perfect! He even leveled out the balance on my speakers.
If you need someone they are really good and if they can't fix it economically they will sent you to someone who can. I highly recommend them for any kind of electronic repairs. That was a great deal as I had convinced myself that I was going to send it to a Harman Kardon repair facility in Santa Monica, and as it turned out - for no reason.
