This is a VZ3 chassis....notorious for cracked solder connections on the
yoke plugs. Look at each yoke on the 3 CRT necks , you'll see a Molex plug
on each yoke. The top two connections are for the vertical winding. There
is a plastic tab that hinders easy soldering of these....carefully clip it
off with a good pair of dykes. You can then access the top 2 solder
connections.

Resolder these and also resolder the vertical output IC401.

This should take care of the problem.

Hi Folks,

I have a mitsubishi Vs-5043 bought around 1997. Couple of months ago,
it started having raster problems. Picture disappears, three curved
red, green, blue lines appear in the middle of the screen. If I turn
off the TV and turn it on after a few minutes, the picture comes back
for around 5-10 minutes but, it disappears and the curved lines appear
again.

I opened up the front and back covers and looked for any obvious
problems but could not find anything glaring (like leaking coolants,
burnt components).

As this seemed to be caused by a over-heated component, I put a fan in
front of the TV and it ran fine for more than a hour and half and did
not lose the picture.

Any suggestions/wisdom? ( for finding the offending component(s) and
not plan-b: fixing a nice fan on the back of the TV!)

M. P.
