Thank You jts1957!
R607 was open on G board.
On A board I found bad solder joints on T501 (resoldered)
Q501 did not appear shorted but I replaced it.
I just want to inquire about T602 before powering up
the TV.
T601 looks like a Transformer but all 5 pins are short circuit?
If anyone could let me know if it should be replaced I will
be grateful.
Thanks Again.

I meant to say T602 has short circuit across all pins.
Thanks

Yes I changed Q601 and Q602
But I don't know why T602 on A board would show continuity between all 5 pins?
Thanks

T602 is a Line Filter on the "G" board. (The schematic only shows 4 pins).
If you have continuity on all pins...most likely causes:
Plug may be plugged into an isolation transformer and you're reading that; or degauss relay could have "welded" contacts and you're reading thermistor/degaussing coil; or one or more diodes in D602 Bridge rectifier are shorted. |

| Did you test continuity out of circuit? |

I must apologize to jts1957 and minnie.
It is T502 that has all pins continuous.
And it is on the A board right beside T501 .
I also checked it on another A board from a Sony KV-34SL40
and that is also continuous across all pins.
I believe it is a Transformer between
PIN Drive/out and the Deflection Yoke CN501.
Even if the deflection Yoke Cable is disconnected it shows all
pins continuous
I did not take it out of circuit.
The KV-36V36 parts manual calls it Transformer Ferrite(PMT)500uM
1-429-408-11.
Thanks

See why it's important to try to proof read before submitting. 
It IS a transformer.
Again, the schematic shows only four pins being used, Pin 6 & 8 are on pin output side through C514 with Pin 1 & 4 in the yoke return. Pin 4 & Pin 6 are tied together, hence the continuity reading. |
