Sharp LC-22CFF4011E

[Jane]

During TV Sharp LC-22CFF4011E repair I found out several parts faulty.
( including a capacitor and a resistor)
Eventhough I have a service manual the values of parts are not given there.
The parts were in HOT part of power supply.
Can you please suggest values that could be OK ?


Thank you.

P.S.
I enclosed a schematic part of power supply - faulty items marked in red -
and also original parts - capacitor has marking like 72M but the leading number seems to be missing.

C - 472 2kv
R - 0.19 Om 5%

QB101 should also be checked, if it is short, then UB101 and its harness probably suffered ...

Thanks a lot for help

But what is the capacitance of tha capacitor? Is it 472 pico Farads?
Yes, QB101 seems good.

Yes, QB101 seems good.

At the end 2 is the multiplier, ("1" is multiplied by 10, "2" is multiplied by 100...), 472 is 47 times 100 we get 4700 pF 2kV (2000v).
