HD DVR not working with HDMI after lightning storm.

Hello... I have the HR22-100 Directv HD plus DVR...we had lightning storm yesterday and i had to reset all of my receivers...all work well except on...the receiver works if I switch to composite cables but will not send the signal through on the HDMI...is this a problem with the receiver and do I need to get a new one?  Any ideas to trouble shoot would be appreciated...I have tried different HDMI cable...makes no difference.  Thanks.
