Hi! I work with tv sets all the time (repair shop) and manufacurers make
flybacks 2 ways: with a bleeder resistor, and without. The withouts are the
ones that can hold HV for weeks sometimes, with a bleeder, hv goes to zero
within 1 minute!
A sure way to tell is this:if the tube crackles for 5-10 seconds AFTER the
power is turned off, the tube is discharging itself (WG vector monitors, and
all Sony tv's I have worked on) If it just turns off, with no crackle, you
have 20-30 kv on the tube...
all recent GE/RCA sets are like this-and the tube can stay charged a long
time...
This crackle test is at least 95% positive, but I still clip a lead to the
outside of the tube and a screwdriver and "POP" the tube...I have not been
hit with 30Kv yet in 10 years, and am not looking forward to the first
time...
Thanks!
