Sorry to hear about your (non)results
In the effort of reducing some clutter on this subject, I'll post this here. If they are successful then I'll start a new thread. Has anyone tried a place called Hi-Tech Electronic Services in Van Nuys, CA? I found their shop after watching a youtube video they had posted about removing the NSX headunit. I emailed them and they said they still do NSX head unit repair so I am giving them a try. Shipped out my unit yesterday so hopefully I'll hear something next week. My headunit is very dead, does not turn on, no sound output, etc. so it may be a challenge.
