TV lost HD signal and color

Good morning,

 

Last night about 10:15 p.m. our Sony TV connected to your Scientific Atlanta Explorer 3250 HD Cable Box went from 'color to Black and White' and also from 'High Definition to a 480i SD picture'.

 

Our bedroom High Definition TVconnected to your 'Cisco' Cable box works fine.

 

Any ideas?

 

Thanks and regards,

Hi rog286713,
 
I appreciate your suggestion.  I had already tried that and it didn't make any difference. 
 
Since my post I have made arragements to have a Comcast Tech come Sunday afternoon to check it out.
 
If I turn off the HD Cable Box and just utilize the TV I am able to get the picture in color although it is still in the 480i SD format.  It isn't HD but it beats looking at a black and white picture.
 
Hopefully the Tech can get to the bottom of it.
 
Thanks again ....
 
Regards,

Hi bigdog99,

 

Yes .. the Comcast tech figured it out but unfortunately I can't for the life of me remember what he did.  Instead of spinning your wheels I would just call Comcast.
