Problem was power supply controling board, one of resistor solder path near connector to power supply was broken.
Hello!
I have problem with Mitsubishi FX10K from 2001, on pressing ready button U700 error is appearing.
I have found out that BKO-R8784 give only 240V, 150V only appear for 1s and fade to 0v after power is turned on and off.
What can cause this problem? Is there any solution?
