Hoover DYN8144D/L-80 blown module

[snig]

Managed to blow the module on this whilst changing the brushes. Thought i had turned it off but plug behind cabinet and still on !!
Anyway, owned up and order replacement but machine is still dead. Looks to be the right programmed board according to connections but see there are several listed. Am i likely to be missing something or would the wrong module be the cause. board fitted was hvr49027992

Whats the 3100 number as there will be more than one listed for that model

that module is for a machine with a serial number starting from 1231
if its before its a different board

3100439913080590 machine is dead, no display. Would the wrong module still at least light up display ?

dont know if wrong board will cause problems but from that number you have correct board

assume you have checked power to the machine
was the board sealed, have had used faulty board from connect

the programme selector switches live on and off, is it working

my next action would be to check the power supply on the new board to see if its working

not sure if front panel has chips on it but if it has you may have blown that too

i have power at the main module and pretty sure it was sealed when it arrived. Looks like i’ve possibly damaged the display as well then !!!
Costly mistake
