Title: Toshiba 32av615bd lcd tv
Post by: yellowpinky on August 12, 2015,04:23:25

Hello Group,

I have a Toshiba 32av615bd lcd tv that intermittently changes the input selection.

I have unplugged the function switch board and it all works ok.

After replaced the micro switch and re- connecting the fault is still present.

The only items left on the board are the surface mount resistors.

Can anyone supply me with the circuit or values.

Thanks Ian Harrison (Sound and Vision)

Thanks you Watteau for the circuit diagram.
Most or the resistor values are different to mine, and there are no caps fitted.
Either someone has fitted the wrong board or there are different control boards fitted for this model.
