More information transmitter unit taken completely apart:
6 ir infrared leds smd 5v regulator 2 TA2008 5v Am/Fm chips 1 DpDt slide switch 1 recifier diode 1 cap 25mfd to 100 mfd by size not tested yet. Need find cap tester in garage Looks like left channel set of 3 leds go to 2 npn in some type ir circuit and also 1 TA2008 5V Am/Fm chip Looks like right channel set of 3 leds go to 2 npn in some type ir circuit and also 1 TA2008 5v Am/Fm chip This is all components inside ir infrared transmitter and their many smd all over board which tracing these will be a nightmare If any member knows how this all interfaces please let me know.Theory would be great. If knew the theory how all goes together i should be able to repair it. best regards, Ralph Sac |
