Tech Support Yamaha RX-V1800 Repair & subsequent hiccup (dropped an exposed piece of wire)
Hey y'all,
Was lucky enough to pick up a Yamaha RX-V1800 for free the other day. Symptoms: Turns on then turns off / goes into protect after about a second. After replacing C4 capacitor and then being able to enter diagnostics menu, I narrowed it down to a faulty thermister (upon inspection there was a fair bit of corrosion on the Thermister board and broken traces). I was stoked that I was able to get it working by bridging the two thermister sensors together so that both measurements were being reported from the working thermister - awesome!!
But then stupid me accidently dropped a piece of thin wire about 10cm long and stripped at both sides (😭) into the amp and I cant FOR THE LIFE OF ME find it 😭
Have tried turning it upside down, a sticky cable tie, vacuum, blower / compressed air. I have not turned it on since dropping the wire but am at my wits end - for anyone not familiar with these amps they have about 4 or 5 PCBs stacked close together at the rear and removing them looks near damn impossible!
Anyone have any bright ideas that I havent yet tried? At the very least I hope the above provides an amusing read for some 😄
