I have an EBD LE machine that I was working with to solve a Flickering Display issue. Someone posted that I should check the High Voltage Regulator section for C26 with bad solder joints and to check the voltage at TP2 and TP4. When I check the voltage at TP2, it is 230-240v and the same at TP4 (which I understand is correct). I am being told that TP2 should be around 190v or so and should be adjustable via the Pot on the board. I cannot adjust via the Pot as nothing happens when I turn it right or left.
After resoldering the posts of C26, my flickering display problem was solved but now I still have high voltage at TP2 - any ideas on what to replace would be appreciated.
