TV came in dead, HOT (Q3208) tests OK, main fuse OK, no horizontal
drive. Found open horizontal drive transformer (TX3285) and leaky drive
transistor (Q3206), replace with something similar off a junk board, now
when ON button is pushed TV doesn't fire immediately and sometimes not
at all. Monitoring the horizontal signal I can see a very distorted
horizontal drive signal, I'm thinking the transformer and/or the drive
transistor parameters are off. Could it be something else? What is the
chassis number for this model and where can I find original replacement
parts for this TV?
Thanks again gentlemen,
