errors XRE 03044 and XRE 10007 - XFinity

I am having trouble with these two errors for month now. Only on 1 of 3 tv's in house and not the one with the dvr. Ive had techs out to the property twice both times for several hours. They rewired house, switched out boxes, etc... and i still have problems. No reason to call them back as comcast techs cannot solve the problem. Where do I turn now?
