The light on the screen
comes on and there is a buzz, but the numbers on the display don't come on, so I'm getting power, but no numbers or reception
. I hear a faint click when I cross frequencies with the ham button down, but nothing else. There are a couple of plugs inside, one marked 27 and another marked 28. The one marked 27 will fit either the socket marked j 23 or the one further out marked j 24. The one marked 28 fits nothing , as it is a four pronged plug and the sockets are 3 pronged.
The schematics were too faint to copy or read.
