Thanks for ALL the great helpful replies everyone! I checked every tip given
and performed that I thought it needed. Lastly I DID solder all the large
yoke plugs, (there were some very small ones on there also but I only
soldered the large ones) and so far it has been playing flawlessly - Only
time will tell. I did find coolant fluid on the Main SMPS board and I
cleaned that up VERY well, problem was still there after clean-up. I even
made a large plastic deflector for future prevention of any coolant that may
leak out once the set warms up and coolant leaks out the expansion camber.
Soldering Yoke plugs helped BUT ONLY time will tell. I'll post in a few days
if all is still ok. Thanks All.
