Hi Guy's Got one of the above with no sound.It's an odd set this one, chassis is mounted in a large metal can.The signal panel connects to the screen & speakers via a large plug & socket mounted on the back of the can. I think the audio i.c. is type MP7722DF,which can be ordered from C.H.S.but I have two fuse/burnt resistors on the signal p.c.b. marked R462A & R463A any fellow engineers know what value they are. many thank's & a very Happy New Year too you All. Maff. :dance:
