Customer said for a long time it was intermittantly losing it's
picture,tho the sound stayed.Then it finally lost pix and sound and was
dead.
I find no shorts,HOT,SMPS all seem OK. I did notice the vert output
IC561 had pretty bad ring cracks on all pins.(Not lose but visable rings
around them.) I resoldered it,the H. drive transformer,some ground
stakes at edge, HOT,etc.Powered it up with perfect operation.Shook and
tapped chassis.Has been on now an hour OK.
I should have just ran it to duplicate the symptom,but no,I jumped right
in. Any history of this senereo on this model?
Would the vert iC561's pin solder cause this?
