Parasound T3 tuner won't turn on
Recently bought a used Parasound T3 tuner and A23 amp together, then bought the P3 preamp on ebay. Got it all hooked up but the tuner wont turn on. The on-off button is backlit, but the "P" logo does not light up, nor does the display. Tried plugging/unplugging - didn't work. Tried using the remote - nothing. Tried using a 12v trigger from the preamp - did no good. Tried resetting the microprocessor per the manual using a toothpick in the unmarked hole near the RS232 jack - did nothing. Previous owner said it was working when he took it out of service about a year ago, and I have no reason to doubt him.

Any ideas greatly appreciated.

I would look for a good reliable tech. Any good tech would be able to take care of your problem. I deal with Audio Classics for all my Mac equipment and they do repairs. Not sure if they would work on a Parasound but you never know. Just checked their site and they are closed due to the Governor declaring all non essential business close in NY. I guess our hobby isn’t essential, lol. Perhaps others will chime in with a good tech. Is there an on/off master switch on the rear panel? |
There are a few tech repair shops near me in Augusta and it will probably end up at one of them soon. There is no master on-off switch on the rear panel. Friend of mine said I should discharge the caps with a wire across the 115v terminals. Sounds risky to me. What would cause the protection circuit to lock up, and how can I unlock it? |
Remove the top and check any blown fuse inside. https://www.hifishock.org/galleries/electronics/parasound/source/tuner/halo-t3-1b-parasound.jpg |
