At the time I had a Rifa experience with the 4D, I didn't know as much as I do now. Today I probably would have fixed it instead of trading it away (it was not scrapped).
When I tried taking the power supply (an ACDC unit) apart, I couldn't find any vented capacitors. But I was not specifically looking for metallized paper, and I didn't check inside the inlet filter (which may have been a Schaffner for all I know).
The odor was very strong, redolent of about a pound worth of burning hair. It also was very "sticky" and stayed in the corner of the room for over a month after power was removed.
The machine kept running and probably would still have started if I could have handled the smell.
