First I want to thank Jim for this excellent TV repair form.

My 27 Sony TV with AA-1 or SCC-F84E-A chassis is dead for quite some time. I do have schematic for this TV.

I found Q591, Q601, Q602 were shorted between C-B-E & R607 was open.

I replaced all of the above and TV worked fine Very Happy . After for 40 minutes a bright vertical line appeared on the screen and immediately went blank and dead Shocked .

From the above symptom, I understand that some other component(s) in the horizontal section is caused to fail above components. If FBT is bad/short it would not allow TV to operate for 30 to 40 minutes.

Any help for my issue?

Thanks for your suggestion. I need to order two set of parts later. I will try your suggestion and post the result later.

Do you think I need to check any other components? besides resoldering Hor. Driver Xfmr?
