Vertical Instability

I have a 2001 Mitsubishi vs-45607. The problem is the picture is
dark,
squeezed top to
bottom, and it has a little vertical jitter. I've done a lot of
research on
it, and what I've found is that the 9V regulator is most likely
bad.
unfortunately I don't know what it looks like. I know I could
replace it if
I knew what it looked like so I could get the position of the board
to order
the part. Anyone have a picture of where it is on the board or what
it
should look like? Or any description in general. I can send a
picture if
needed. Don't fret, I got this TV for free and I am confident I can
fix it
if I can
decide which part it is. I have the schematic and such for it. I
was mainly
hoping someone could send
and example picture of what it looks like or give a description.Or
just
confirm my opinion that i think it's a black chip with a heatsink.
I do
understand the dangers of
the high voltage that lingers in the tubes. I have the board
removed from
the TV. I know the difference from a resistor and a capacitor, but
I'm
unsure what I'm looking for as far as the regulator. any help would
be
greatly apreciated.
I bet you're wrong. While voltage regulators sometimes fail, it's not
typical. My guess would be electrolytic capacitors drying out and
causing the ESR to go up. We buy very few regulators but 100uF 25V
and 47uF 35V caps in thousand piece bags. I would pay particular
attention to any coupling and bypass caps in the sync separator and
vertical deflection sections.
Good luck sorting it out
