Jason,
In case this is similar to yours..from Tech Repair CD:
Pan\CT32D11E\HV comes up momentarily and unit shuts down.\\\\Verify main B+
across D825 Verify vertical
output @ IC451 pin 2 Check pin 7 of the microprocessor IC001 for 1.6vdc. If
higher suspect over current
shutdown\Pin 7 IC001 read 4.7vdc (too high) which indicated either over current
or a false shutdown. After
verifying the unit was not going into over current shutdown\IC801 (shutdown
photo coupler)* was replaced
and repaired the unit. Part number: PC817X2\\\\\\

Subject: [TechAssist] Panasonic M# ct-32d10b shuts down
Hi everyone, I have this tv that was struck by lightning. I found D825
avalanche diode shorted on the 130v
line. I changed it OEM and now the set turns on and shuts down after developing
HV. The HV isn't to high
in fact I think it is a little low. Current drain doesn't seem to high. All
supply voltages are there and
secondary of scan supply is there for the moment it is on. I can't seem to
find anything wrong.
I did jump the relay and hit the power button. the relay clicks off but the hv
stays on. I get a picture,
full deflection, just no osd or system control because it thinks it is
shutdown. Also, when it shutsdown
it will not turn back on until the unit is unplugged.
If anyone has any suggestions they will be welcome.
Thanks
Jason
