The driver transistors are not on the CRT boards they are on the main
boards. All thought solder looked good re-soldered around driver transistors.
Has been playing about 24 hours now no problem with color changes or shut down.
It did have a convergences problem but this unite has an advanced convergences
the customer can use and it works well.
Only resin I can see going into convergences set-up would be if the green
crosshatch were off and it was good. Thanks guys.

Look for leaks----very regular problem with those, causes very wierd

IN the interboard connectors. Disconnect them to verify no fluid inside the

Maddening. One drop and it migrates under an IC on the signal board. Not
sure if its this model.
Also--Isnt this the one that has bad driver transistors on the crt modules?
Mits's web site must be down for maitenence. Green driver transistor
would probably check good but still be bad.

play with good picture until this happened. He had it on when we got there
and had a good picture. Has been playing about two hours here at the shop
with good picture. He also said the longer it was off the longer it would
play before doing this. Thanks
