Tek492 blank CRT. Please help


pjwalczak@...
 

I have an old Tek492. Bought it second hand, but was working fine
for a couple of years. Today when I have switched it on, after a long
break (almost a year) - it powered OK, all controls seems to be ok,
but there is nothing shown on the CRT.

Can anybody share some tips what can be done to find the cause
and fix it ?
