Zenith SL7573W top of image collapsed

[Chris]

I've got a Zenith SL7573W from Aug '93, woodgrain cabinet (if that
matters). The picture looks decent, but the top is collapsed, about an inch
or two is black, followed by white horizontal lines through the next part of
the picture. The rest looks normal. Is this a common failure in this set?
Any suggestions would be appreciated, as I am gathering that this shouldn't
be too bad to fix.

Thanks!

Change filter caps in vertical circuit.
Dont check em change em.

 

[Chris]

That is what I suspected might be the problem. Is there a place where I
might be able to find a schematic or even just the values on the filter
caps? I figure I might as well order a set.

Thanks,
Chris

That's a common failure in many different sets, bad electrolytic
capacitors around the vertical output chip, it's a good one to try
repairing yourself if you know something about electronics in general
and TV safety.

You dont need a schematic just pull them out and change them.
Locate the IC LAxxxx and replace the caps around it.

After you replace a few caps by putting them in backwards ands usin
the wrong values, and screwing up the pc board by to much heat o
running solder bring it in to your local repairshop to have them fi
it for more than what it would of originally cost you if you would o
took it in in the first place
