Would anyone have a troubleshooting method for this CT36HL43G. It had an open 6.3 fuse and have tried replacing the thermistor D803. I have checked HOT and flyback rings okay. It has a self diagnostic feature that basically doesn't work at all. Any help would be appreciated.................

Thanks, Bill G.

So whats the matter with the set. I hope you replaced that fuse with a
time delay fuse or it will keep blowing.

Use the orig part XBA2A00101 6.3amp 125v.

Yes that was the first thing I replaced. The set has an extra PS thats
off on the side by deflection. I don't know were to begin?

here are some tips from panasonic's asc website:

CT36HL42CF DX3 Unit shuts down upon power up Check for an open vertical
deflection yoke
CT36HL42CF DX3 Will not power up - 7 volt is low Check DG board - Possibly
loading down the 7V line
CT36HL42CF DX3 The unit will intermittently shuts down, especially in areas
of high altitude, and must be unplugged before it will turn on again. Arcs
in CRT socket or spark gap, Click here to see remedy
CT36HL42F DX3 Will not power up - 7 volt is low Check DG board - Possibly
loading down the 7V line

CT36HL42UF DX3 Unit shuts down upon power up Check for an open vertical

CT36HL43G DX4 Shutsdown due to HHS detecttion Leaky D1504 and D1503
CT36HL43G DX4 Dead - missing 3.3v Check the following connectors A21, A22,
A23 - p/n K1KA30A00128. They may be bad.

The infamous Panny blown the 6.3
Well supposedly after a while the crt's draw
to much current and cause the fuse to blow...

I would use a slow blow 6.5 or 7....test for
about 24 hours....and turn tv off and on another words
cycle it on and off randomly at least 12 to 15 times
within the testing period...

If you use the original 6.3 you can actually see the
fuse slightly bend inward after a few uses...

After this happens several dozen times or less it will
get weak and blow again...

Slow blow is fine....

I will check the site for some info I think there
is a bulletin on this...there was also an issue
of the crt boards causing this as well...

See ya,....

Bill....
I did not find any thing new on Pannies web site
about this....I did see to check d808 for some
similar models...dont know if your set has this
diode...might want to check...

If it has it change any way....the degausing
circuit can and has been known to cause this
that is for sure...as well as the crt drawing to
much current..

The other issue with the crt board is for intermittent
shut down and have to unplug set and plug back
in to get it to turn back on...

see ya....check to see if you have D808...

After replacing the 6.3 with slo-blo there is 100% dead. No
clicks,nosqueal,not even a tick. This set has like 4-6 relays and all is
dead. I will have to do more homework on the schematics. Even the self
diagnosis is dead.No lighting of the led on front panel assembly. I was due
for a dog..........

Don't despair, Bill, we all get one sooner or later. It sounds like you lost
all primary's. Check for 5 V. first. You will need that to get at the
startup. Raw B+? If you have the schem. you will be able to find it, I just
know you will. Good luck Bill.

Been there done that!! I have the 7 and 15 volt standby. And after jumping
one of the three relays on the pwr/signl board I'm still stumped?? I checked
all diodes,transistors,resistors,and caps. I have found no fault in the
Primary P.S. I will wing it with the secondary tomorrow.
