Hi again,
I'm about ready to take a 3rd look at this TV.
I need to know what the "exact" B+ voltage is supposed to be.
I am thinking that 136 volts is about 6 volts too high. Tried everything I
can think of to get it lowered.
Patience and time, will win !

Hi Members,
This Panasonic TV shuts down after 5-10 minutes. Has a good picture. H.O.T
runs cool, Vertical runs hot, but holds up OK.
The B+ measures 136 volts. It seems too high. The voltages on the Reg. IC
(STR58041) reads from hot ground:
Pin # 1 = 97.2
2 =136.6
3 =? (can't read)
4 =138
5 =142
Working without a manual (As usual). Uses Sams # 3891 (which I don't have).
I have checked Q801, D825, D823, R829, and replaced C820 (10 @ 100).
Soldered the hell out of everything in the Reg. ckts. Replaced the Relay. No
help !
Any help appreciated,
LLW
