Question about Toshiba CF30F40 30" TV
There will be some loose contact in the circuit board of your tv. May loose sodering in the vertical output stage; around the ic used. Try resolder almost all the solderings around it will solve the problem. Vertival sync; signal may not absent in the main ic too. Anyway resolder the main ic too. Surely it will solve your problem.
