    Infinity sub amp and Onkyo 2 ch reciever

    Hey all, looking for some advice

    First i have an Infinity sub amp from a ps10 that turns on, makes buzzing noise louder and louder till it shuts itself off. Noticed someone on ebay fixes them so it must be quite common.

    Anyone have any idea on what goes out on these?

    2nd i got a 2 ch onkyo tx8050 reciever that has never had any speakers hooked up, it was used as a controller for an old bose 5.1 amp they sold way back in the day, so only thing used was the 2ch preouts fed from the optical from tv. It turns on with half dim display and then protects or shuts down after about 5 seconds.

    Looking for any insight. Im not new to fixing or soldering. I soldered some new parts on a $2500 motherboard out of my Roland versa cam and also a bunch of not so touchy parts as well.

      Looking for Dump for P87C51SBPN (Concord Infinity Elevator)
      by vlady carp
      Hello, colleagues!

      I'm currently dealing with an issue while repairing a Concord Infinity elevator. The microcontroller P87C51SBPN used in the control board has failed, and I need the original firmware dump in .bin format to replace it with a new processor.

      What I've done so far:
      • Diagnosed the issue and confirmed the microcontroller is the root cause of the problem.
      • The original processor is beyond repair, and I wasn't able to extract the dump.
      • Reached out to the manufacturer (Savaria/Concord), but I haven't received a response yet.

      Running out of Ideas, hoping someone smart can provide some for my ONKYO TX-SR353 Receiver
      by CDNBrewer
      Hello Everyone,

      I have an Onkyo TX-SR353 Audio/Video Receiver (5.1 ch with HDMI) that I am having a really hard time diagnosing and I'm about to throw this in the junk and go buy a new unit that is on sale until the 7th.

      Symptoms:
      • Intermittent (part of the reason why i'm having a hard time isolating problem), sometimes will work for 10+h at a time without issue
      • Original symptom was wife reported loud banging noise (like someone was banging on the wall with their fists) from the LEFT SURROUND speaker and then the unit shut off.
      • I swapped the Left and Right surround

      Onkyo HT-R390 no sound output, video output ok
      by FrancescoV
      Good morning everyone,
      I'm trying to repair an onkyo ht-r390 that has no sound output, despite the volume being at maximum, the rest seems to work; the video output signal (coming from an hdmi input) is present, but the audio is absent. Similar situation if I send an audio signal from any input I have no output.

      The firmware reported is the following:
      M:1.00/11107BLP
      D:?.??/????????
      O:1.00/11107AL

      The DSP firmware given the question marks seems corrupt.

      On the BCHDM-0678 - 25140678 - QPWBCHDM0678A0 board the chip that usually seems...
