Re: Sony MDS JE480. Hum.
OK.
I had another closer look today, tried a theory and it worked. The hum is gone.
I noticed, the 4 pins on the RCA plugs that go into the board. I saw what looked to me where there had been a further 2 pins which had been sheared off at some point and a corresponding position on the board where 2 pins probably were soldered to it. I cut the legs off a capacitor, soldered these to the RCA plug and then soldered all back on to the board. Assembled the unit, hum gone!
Now if I could get a new plug, as I do not fully trust my repair. I think if it gets any type of knock, it will break the repair and back to the hum. Anyone know where I could get the plug?
