Hi
I gather the section where the mains comes in and several large electros,
rectifer and reg IC is the switch mode supply, the area with the trippler
is
the horizontal ?
does that make the area with smaller electos some kind of large heatsunk
IC
the vertical, if I'm looking for horizontal bars across screen, probably a
electro in the virtical - yeh, what does history have it, small
ones
or big ones, I'm trying to teach my little bloke there is more to just
sitting in front of these things
Cheers


Follow the yoke wire the the pcb, not far from that you will see a single
inline IC bolted to a heatsink. That is the vertical output amp. Mostly
the higher voltage caps near that area will fail and may or may not leak.
Heat will just dry them out. If a visual inspection shows no burned board
traces or blown vert IC, then for what the caps cost - why not just change
them all near the vert and see what you have from there.
