    Hi,
    Got an excess-to-requirements Sony TA-VE215 home theatre AV Amp with a few issues.

    Works fine *except* when it's cold the sound goes 'muffled' for a while. A sharp thump on the top fixes it. I think the problem is relays. When the unit warms up the relays can be heard quickly and randomly switching. Then the sound falls. A thump and the relays switch and all is good. Doesn't happen when warm.

    Open the unit shows three 12V relays at the rear of the PCB. Pretty sure these are the culprits.

    Wife got sick of it and bought another unit coz even though I said I reckon it could be fixed - I never got around to it.

    So if anyone is willing to have a crack at fixing it - it's yours.

    Comes with 1x active sub, 5 x speakers and remote control.

    Collect from Montmorency 3094

    That sounds right,
    Why don't you try opening the relays and forcing them closed,
    or shorting their switches?
    Someone will get a bargain.

    a faulty relay is so rare these days idd put my money on a dry solder joint interrupting a circuit controlling the relay. its just a guess tho, i just bought a faulty harman Kardon amp im fighting with atm.

    Could be simple; could be the hardest fault known to man kind, someone has to open it and see.

    I'll gladly take it!
    I'm hoping to build my own amp soon and fixing one would greatly get me on my way to being a bit confident with them!

    I can pickup at some point this week or maybe the weekend if that's okay with you?
    I'm happy to throw some brew your way :)
    (ignore my location, i actually live in brunswick now, so quite close)

    I'd strongly suspect cracked solder joints, most likely on the output transistors. Could be on the relays though.

    Well, the amp is gone now. Cracked solder joints was the guess of his.

    Cheers all,
    Glenn
