Sony KV27S42 Vertical IC Runs Hot

Hi I badly need help. I am repairing a Sony KV 27S42. Original trouble is no picture. After changing all defective components, picture were back to normal except the vertical IC goes very hot after 5 to 10 minutes. The color IC on picture tube circuit goes hot, too, otherwise, picture is normal. R1759 in the picture tube circuit is also burned and doesn't know the correct value. Any help or hint would be greatly appreciated. Thank you very much. Bobby
