Look for bad solder joints everywhere. This is a very common problem on the
Pioneer sets. Also, are all of your low voltage supplies coming up?

I "borrowed" the vertical deflection IC to fix the 5075, but I found a
source of that. When I got it the power supply was dead with several
smoked
parts, I repaired it so it would turn on for a moment then shut off, but
then I forget what happened but it got so it wouldn't turn on at all
again,
I checked with the known good power/sweep board and it turns on for a
moment
then shuts off so I'm pretty certain there's a short somewhere on the main
chassis, I haven't really dug into it yet though. Before when I held the
power relay on it would display a slightly distorted raster but no pic and
no control response.

Those two would be mostly the same, as are the SD-P4575, SD-P4573,
SD-P5575,
and PRO-97. Other models with the SD-P50xx prefix would not be as
similar.

What kind of problems does your unit have?

It's a SD-P5073, but I just fixed an SD-P5075 and the relevant
internals
are
identical.

The xx in your model number is the important part if you want parts
that
will be of any use to you.

I have one of these that I've been working on for quite some time
now
and
recently got another which I was able to fix with some part
swapping,
but
in
the process I found that all three sub-chassis's have various
issues
so
I'm
hesitant to spend a bunch of money on parts with an uncertain
outcome.
Does
anyone have one of these with dead tubes and a serviceable
chassis?
Contact
me with price.
