Need Help VP 300 Cyan and K not firing.

[$Rob41god]

Hello all,

I have a VP300 that recently blew the servo board, I replace the servo board. After replacing servo board Cyan was overspreading and then stopped completely. Swapped the Y and M with the K and C and it did fire so I replaced the Print head board and the F2 fuse and now it still prints Y and M but continues to blow the F2 fuse, but at least all the heads fire when they are swapped can anyone shed some light on this please.

Thanks Steve

Blow transitor on your mainboard. C4131 or A1746

Does the Main board need replaced or are the transistors replaceable?

Unless you are good with a multimeter and a soldering iron, remove the board and take it to an electrician to test and replace them..usually only one blows but knowing which one it is, if you dont know how to check them, is the problem..

4 there and 4 on the other bank

The transistors are only about $2.50 each.
