Hi people I have problem with MIII 1995, When I will shoot appear control error. after that I go to service calibration and start and appear KV sense control error. the KV card dont have any led on . Please let me know what is the problem??
Control Error means the KV sense exceeds +/-12.5% of setting during exposure.
There is no KV card. It is the High Voltage Generator Control Board. Besides KVP off calibration can cause Control error, the mA overshoot can also cause Control error. To calibrate mA, connect a volt meter across R42 on the Tube Control Board and Connect a storage oscilloscope to the ungrounded end of the 10 ohm calibration resistor.... If you need additional help, contact me at edwardhyan@yahoo.com e-mail address.

Check small fuse on side of HV module under clear plasic cover - I think it is 1/10 amp it has a spring and resistor inside.
