Power to print head thermistors failure / fault

Need help about this error.Thanks

99-405 Hard Refer to IME Controller test points TP703-706 (Lower Left corner of
the board, with labels HD1-HD4 to indicate which head)
Check at each test point.
• If the voltage is ~3.2V, then that head is good.
• If the voltage is ~2.1V then the data cable has an open contact.
Install a new video cable, PL 92.10 Item 7, for the indicated
printhead.
• If the voltage is ~0.02V, then it has a thermistor / temperature
error, check the PEST fault history, dC123 for shorted triac.
Unplug AC heaters to that head, if still bad, install a new printhead.
• If the voltage is ~0.3V then check the cable on that head and
look for a thermistor error on another head.
If all 4 voltages are OK, it may be intermittent, try POPO to catch the
fault again and measure immediately.
Refer to 91-805-00, 91-806-00 Printhead Communications RAP

That is a very rare failure code on a 92/93xx ColorQube.

Suspect video cable failure. Esp., if someone has been playing around in there.

92xx IME's are also junk. Suspect IME failure after excluding video cable / print head.
