Al This LM7812 is in a TV power supply without any raster or sound.
Al When I power on and test the voltage input at pin 1 I measure no
Al voltage there but on checking pin 2 (output) I get 12.12volts.
Al My question is: how can that be? where is the voltage coming from when
Al the input is not there?
Al Thanks to anyone who might be able to eplain this one.
