Sony KV35V36 Repeated failure of Q602, Q601, VDR601 and HOT.  Replaced flyback 
Q602, Q601, VDR601 and HOT. After first failure found weak C502 on deflection 
board and replaced.  Replaced parts again and TV played about 2 hours, HOT 
running hot. Blows HOT and power supply. Helping another shop here in town on 
this one. Found a couple of tip on Ring cracks around pins of T501 Horizontal 
driver transformer and T603 reg drive transformer for different models. He said 
he thought he had already re-soldered the transformer. Thanks group.
