[TV] Re: Panasonic PT61G45

Hi,

There are two shutdowns, one that latches and one that the set can't be
turned on again after it went off.


If it latches (you have to unplug the set to reset), then you have a HV,
supply shut down (over voltage).

Suggestion: unplug all CRT boards from the tubes. Monitor shutdown line.
Measure B+, Verify deflection (vert. &horiz.), etc.

You have to start somewhere to narrow in on the circuit area.


Good luck.

Dieter.

Hello everyone:
I have been working on a Panasonic PTV  PT61G45 for 3 days and cannot locate
the problem.
I need help badly !!!
It shuts down into protection mode intermittently,some time 1 hour other
times 1 day .
I have checked  no cold solder joint found.
Right now I have 2 PT61G45 TVs have the same problem sitting on my bench
Any suggestions appreciated.
Thanks

Ted  Lee
