You don't want to look at the DC voltages....You want to look at the duty
cycle of the 2 transistors with a 'scope. Should be 50 to 52%.

Subject: [TechAssist] Question on Sony 32V15
| Hi there is there anybody that can tell me whether using a variac set to
30v
| ac I am reading 78v on the collector of Q601 and 39v on collector of Q602.
Is
| this correct or will this thing still take the trans out at full voltage.I
did
| find a partly shorted HO trans when this came in but didn't show until I
| isolated it.
| Thank you for any assistance
