[TechAssist] Re: Toshiba TV model CE36G18

More information.
Tv shuts down If HOT is active. If colector of HOT is removed microcontroler
will not turn relay off.If I reconect HOT colector and
 I jump the relay. The Hot is active and High voltage is on and It does not
show any high curent.
I wonder why shut down?  B+  is 127v  Is it low?
