Toshiba M-5900 VCR transformer really hot.

[Antoine Desch?nes]

I've got a Toshiba M-5900 VCR and it's transformer is turning finger
burning hot.(Some screws darkened also)

Since the 2SD1273 transistors were making noise, I replaced them with
TIP121, with a metal case. The collector got shorted to ground.

At the repair shop, they changed resistor fuses and STK regulator.

The VCR works perfectly apart from that.

At least, the VCR components aren't dead, the PSU wasn't plugged to
the rest when it blown.

Should I replace the 2SDs if I can get some 2 for 7$ + shipping?
The channel selector near the preset tuner is also producing whine.

What I'd like to know is if other M-5900s are producing whine near PSU
and preset tuner(door on the top), and if it's really hot over the
PSU.

take your vcr back to the repair shop and have them "fix" your vcr with
the factory original parts.... be certain to mention the whine/noise
and excess heat that you have noticed.

Repair warranty expired, was 90 days.
It was whining before I sent it to repair.
Maybe I could've sent it, but I didn't want to wait an other 10 months
for the repairs.
I dropped it on the corner the day I got it from the repair shop.
Loading and eject motors (same model) started making noise, and I
replaced the loading one who stopped the VCR from working correctly.
The eject motor is still the old broken one(But works)

EVERYTHING works correctly, except that adjustments need to be done :
HiFi, even when the HiFi tracking meter is on max, sounds as if an
inductor was in the signal path(More treble in mono track). Picture is
grainy, there are some discolored areas on the video head, and some
kind of sand in the stripes.

There's also something strange(For a 198x VCR), there is some kind of
buffer in the VCR : It starts recording when I press REC, and the tape
isn't even loaded. It loads a couple of seconds after. When I press
stop, it continues to record for a couple of secs and then stops.

I guess I can change every caps, resistors and diodes in the PSU, in
case one is half short or something like this.
