Sharp Blue Ray and Sharp Aquos TV were working just fine, now blue ray not recognized by tv; screen stays dark but the blue ray appears to be operating. Have tested the blue ray independently and worked fine on another tv; problem has to be with the tv. Cable tv works ok, just don't have a picture with blue ray.

I had the same problem with my remote. I would enter the code and there would be no response from the remote. I looked up the manual for the other comcast remote and the codes are 5 digits instead of 4. Try codes 10093 or 11602. The reason why there is no response from your remote is because it is waiting for you to enter the last digit of the code. Hope this helps.

Try unplugging your tv. And then plug it back in and try remote.
