I have a Hitachi CMP4221 42 plasma and a Comcast HD box. I tried all the codes that came with my controller and even tried to do a Manuel search, nothing works. My remote is the remote that has the five digital codes.I really would like some help if anyone can help me.

Did you get any of the codes to work partially, like the power button or volume buttons with setup code TV/10145 or TV/11145? If you can get the TV to respond to some button, there is a way to add the missing functions to the remote.

no i got no responed from any codes. I actally went home and tried all the codes again after coming to this forum because i was thinking the same thing. Do you think if i had acomcast tech come out can they get it to work.

also should i try both codes and change the buttons even if i cant get a respond.

can anyone help me please

I doubt the code you need is in the comcast remote, which is UEI code tv 10797.

thanks for a reply
