Thank you for your reply. I checked around a bit more and found that my HOT was
shorted. Changed the HOT and the bouncing went away. Went to turn on the set
and nothing. Checked U4101, and I was back to bouncing. The HOT shorted again.
I have just moved and cannot locate my FTB tester. So now I need to ask, what
are the chances my fly is bad. Any other ideas?
Thank you again,
Chad

You should measure about 28 ohms between pins 15 and 16 of u4101.
Voltage on the pins should be around 10.8 when in standby. Check cap
c4118 470uf35v.
R4003 is 33k 2w power supply feeding pins 15 and 16.
