gonk,

Thanks for replying.

I'll be trying what Scott suggested I should do first. If that doesn't work then I'll try your suggestion. If that doesn't do it then I'll send the unit for repairs.

You know, I've been living in this house since 1972 and never had a problem with the electrical power system until experiencing the ones that took the two components named above (those electrical disturbance events occurred fairly recently), so I've been remiss in adding surge protection to my audio/video systems...'til now; I'll be remedying that situation real soon, believe me you!...
