Topic: Need some help Please, Da vinci 1.0 heater error

Hi, couple weeks ago I started a long print. It started the 1st layer so I left it running. Came back couple hrs. and looked like
something went bad, filament all over, head was off table and slamming into right side of table. The table adjustment nut vibrated off so it couldn't get back on table. after cleaning up mess, and seeing nozzle scraped up I desided to do the E3Dv6 upgrade I had parts for but never got around to.

Anyway, Here's the issue. after installing everything I get heater error pictured. I changed to Reperter Host 2.0.5 and Arduino 1.6.5 long ago. Software hasn't changed. I've checked everything I can think of, through it was the heater mosfet on the board and replaced it with same P/N, same error. Do have 12v going in, new heater and thermistor (tried the old ones also).
It could be the fuse, but I don't see one on the board to check if someone could point it out I'll check it. I'm thinking it's R17 the one above heater plug there's no resistance it's marked with 332. Printer is the original model 1.0
Thinking of replacing MB but hard to find and $$$ Any help would be much appreciated.

Re: Need some help Please, Da vinci 1.0 heater error

Any idea's I've checked power supply 5v, 3.3v and 12v ok, resistor R22 has 103 on top, shows 10.2 ohms @200k setting. new thermistor checks 114k @ 68 deg. new heater 3.6 ohm. I'm at a loss. and changed the mosfet prev. stated
