Sony KV 1515 flashy picture

[Keith Park]

had this since new, was sitting, took it out and had no audio and a picture that has lots of horizontal lines and blocks of flashy in the picture, sometimes the picture will go to garbled color, found an open resistor and fixed the sound, but the flashing goes on, unplugged the tuner, same, so thats not it... cant find any bad solders, doesnt act physical, no leaky caps... ideas? working without a print on this one too.

Thanks

Keith
