[SOLVED] Racal 9087 signal generator error 80

[clivew]

I wonder if anyone can help with this fault, presumably in the 11-1534 (19-1047) module,
as the reference oscillator is fine.
I replaced all electrolytics a few years ago and cleaned the boards also.
The machine has been unused for a year or more, and was fine when last used:sad:
"51" shows in the memory display on switch on, "80" shows in it's place when "display error code" is pressed.
I have dismantled it and can't see anything obviously wrong.
I know it's a lot to ask, but any help would be really appreciated.
Many thanks,

Clive

place the machine under 200watt bulb for few hours then again check it if it works then fine. because you told that when you used last time it was working. this technic also works
