For quite a while while in standby it would click click now and then.

Now it cycles on and off (PIC and Sound) every 15 sec's or so...
channel selection and remote don't work well at all....

MDB circuit board led's cycle thru a number of different display sets rapidly while the PIC/Sound is on and then stops with center three lit and then PIC/Sound goes off...and then LED's start the sequence all over again..

With set in standby the LED's do the same as above over and over and over.

No relays clicking during all of this except at main power on.

I have a service manual but.......im still THINKING,,, Smile

Anybody else?
