    I have this onkyo SR309 not working but again did you say it is a sanyo unit I am freaking out now.... Santo is not the most reputed home appliances system around... Just midrange garbage then.... .that was a quick fix 🔧... Nice work..

      A lot of Sanyo parts inside... :-) Sorry to tell you :-)

      @Dubious Engineering I am certainly disappointed.... Had a bad experience with sanyo products in the past.... And bits and parts from sanyo does not instill confidence..... 😟😔😞

    Hey I just bought a denon 3803 when I got it home I realized inside it's DIRTY!! As much as in this video. Can I vacuum, light brush and blow off the circuit with can compressed air and then go over with isopropyl to clean and lube the jacks/pots with electrical spray???? Sound like a good way to do it. The good thing is my unit is fully functional, God knows how lol.

      That sounds exactly like the cleaning process you should give it!!!

      @@DubiousEngineering I keep hearing about EMS from vacuum cleaners and that it's not safe. I was only going to use it at very low suction. Ok?

      This is exactly what I was looking for. I realized my parents HT is dirtier than this and I'm going to clean it. I hope that it works after this, otherwise I'll have tu buy them another (.V)

    How's it going, Howard. Hope you're keeping away from the lurg.
    Still need to fix my Onkyo TX-SR607. It has the usual dodgy soldering on the BGA DSP chip, so I bought a new (pre-balled) chip.
    Need to throw it in the reflow oven at some point, but I don't have a proper controller for the oven, so it'll be a case of watching when the temp gets above about 260C.
    The BGA version of the chip gets way too hot, so weakens the solder over time. They really should have put a heatsink on it.
    The older model you have there looks to be mainly non-BGA, so probably a fair bit more reliable.

      Hi Ash! Great to hear from you!! --> Likewise mate... keep clear of the nasties!! In the past I have got away with pre-heating the family oven to 200C (max), then quickly using a hot air gun and JK thermocouple to re-solder those ball grid array buggers... they really are a nightmare!! Onkyo Fffed up big style!! Fingers crossed Jon's unit keeps going after this service...

    Liked that bit of Tocatta and Fugue (have I spelled either if those properly?) although it did sound a bit Stylophone at the end there. Of course, maybe that's how Bach intended it... Cheers mate, stay healthy.

    reflowing is a waste of time for sure the fault will come back you need to use the old lead and tin solder and redo the hole board same problem happened with the ps3 and Xbox 360 crap solder

    • @DubiousEngineering
      @DubiousEngineering  4 роки тому +2

      I hate lead free!! I’m sure that’s not good for me... but!!! Leaded solder and flux runs so much better with a shiny finish!! Everyone wants their dogs to have a shiny coat!! Eat lead!! :-). Genuinely thanks for your thoughts and feedback... stay safe :-)
