RCA TV Chassis ctc177
 

I have in shop for repair a RCA CTC177 I think I know what problem is ,
but want a second opinion. When turned on from cold has no sync & b&w
out of sync bars on screen. Leave on & approx 1 min color comes in &
rolling vertically another 1 min stops rolling & good picture untill
turned off for several hours. I think it's in the T chip but hate to
change it as it is a 64 pin IC. Any body have an opinion

Check for capacitors in vertical section for low value.

Usually an IC problem shows with heat, not cold.
