Need Help Roland SP300V no heat value on print platten

Hello everyone, I have noticed on my SP300V there is no heat on the printing platen, there are no errors but when I go into the temp settings the drying heat values are working and the platen is the correct temperature. The Print setting does not move when I adjust for any setting, the plate is cold also. I'm thinking it would be the thermostat or thermistor but, when I get ahold of my Roland tech he's not sure on how to test. Being a mechanic I was debating on switching the thermostats first and go from there. Anyone run across this issue before. Everything is working properly except I have to press pause for the printing to begin. I am suspecting it has to go through it's heating cycle and I can over-ride it with hitting pause to begin printing.
Any help would be great, thanks in advance.
Trevor.
