    Hi,

    Does anyone know anything about repairing a Hantarex US250 or have a working one for sale? I’ve just had my chassis reconditioned but the monitor won’t power up. The fan kicks in, then winds back down. I’ve tested the voltage and I’m only getting 115v out of the 135v rail so I’m guessing that’s the problem. I’ve down a load of work on the machine during lockdown - rewired the harness, repainted the metal parts, applied a new CPO. Can’t wait to get the cab up and running.
