Check for MC arcing. Replace the saw tooth plate (LPLTM0386QSZZ) and MC Holder (CHLDZ0035RS57) or use a new AR310NC.
If you have additional memory installed on the IMC PWB, check if a chip resistor is installed on the back of R332 (IMC). Replace the IMC PWB if it is missing.
Make sure firmware is up to date -
Ive had that problem as well. There is a bulletin about the charger being changed so i just pulled the charger out on the machine and cut the teeth off they showed in the tip and it worked for me.Evil will always triumph because good is dumb.Comment

Nice work Lawrence.....A+ my man!
Be careful you dont get picked on by the moderators by showing Sharp official Tech Bulletins or Repair Hints. I attached one a few days ago, then it got removed as it was ''copyright material'' in their opinion.
Does not say that anywhere, plus it is a freely available service bulletin, available to techs. I was left scratching my head, but am willing to play their game.

I hear ya bro.
Funny thing is, the manuals dont actually have the info in them that the tech needs. It is more often than not the Modifications or Update bulletins which are needed and what we are quoting to get the machine going again. Having a service or parts manual will sometimes do nothing.
