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 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.

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,

Re: TV lost HD signal and color

try unplugging the box wait two mintues and plug it back in, if that does not work then call comcast for assistance.
