switch and check the status of the Preheat LED
(D3) on the R3810.
  If the voltage goes above 2V re-
place R3300.
  If voltage is near 0V then meas-
ure voltage at connector J3202
pin 7.
 If voltage goes above 2V
check and if faulty replace
cable between J3303 and
J3202.
 If voltage is near 0V re-
place R3220.
If LED D3 does not come on, check the condition
of the cable between connectors J3314 and
J3810.
 If cable faulty replaced it.
 If cable OK replace R3810.
If LED D3 comes on, check the status of the ex-
posure LED (D31) on the R3810.
 If LED D31 does not come on, check the
condition of the cable between connec-
tors JG214 and J3810.
  If cable faulty, replace it.
  If cable OK, check if the FAIL
