problems with a riviera tv model RT-21PAS
friend Gusman ... what I ask regarding q, trans, salt, hor, carries the chassis tv PX20074 ... it was answered correctly ... now if you have failures in the TV you must open another post ... previously evaluate the received contributions .... then we will analyze the fault ... ok ...
Good morning colleagues, I tell you about the TT2140 transistor, but the TV triggers the starter reley of the source and it is heard that it oscillates but does not turn on the voltages that I have are the following. In the primary of the TM0105U transformer I have 155V in the secondary of the same transformer before the output diode + B I have 42V and after the + B diode I have 72V I want to know if these voltages are correct or if I have a voltage drop. If so, the cause of the voltage drop was useful. thanks and happy day to all
