Electric Pulsation

[consoleguy67]

Hi All,

I have two roundie color tvs that seem to be sensitive to the pulsations in the electric current. I notice it in the incadescent light bulbs in my house also, but not in my flat panel sets. Am I correct in assuming that the electric service is the cause, or is there something I should check on the tvs? One is a 1964 Magnavox comb, and the other is a 1967 Zenith.

Thank you for any advice you can give me.

Frank
