Tried JWEBB's EPROM2 HDMI fix and it has worked for a while. I am now having issues when I change channels from a HD channel to a regular cable channel. Confirmed EPROM2 settings had not changed. Non - HD channels are greenish/purpleish and HD looks good. Anyone seen this issue or any suggestions? I am using a Comcast box and a DVI to HDMI cable between box and set. Any help would be appreciated.
