Sony has been doing alright for me I changed out both ICU chips a year and a half ago and its been great now I have a issue with horizontal lines that are white and the fluctuate up and down on the screen anyone know where to start or is it time to buy new.

Thanks

Forgot one more thing the flashing starts when the cable is attached (its not the cable, I checked with a different TV ).
