To get the codes, just use a IR detector such as  the TSOP4138, hook up an =
logic analyzer (and power, if its not obvious) and you can read out the cod=
es that are being transmitted.  If I recall, it's the device ID first and t=
hen the command.

Subject: [EE]: IR TV Remote codes

I have a TV and cable company remote that don't play nice together.=A0 The =
cable company remote (Comcast, XR2 remote) will not control the TV's power =
or volume, no matter what "codes" I program the remote with (I tried ~30 di=
fferent "suggested" codes).=A0 This is apparently a common problem with thi=
s TV (RCA L32HD31R manufactured by TTE Technology) as there are several web=
sites documenting the same problem but with no solutions that I could find.

So, is there a way to "steal" the code from the RCA TV's working remote (so=
me sort of IR sensor?) such that I could then program the Comcast remote wi=
th the correct code?

This is one of those minor annoyances in life that is probably not worth th=
e effort, but darn it, I hate losing!

Thanks,

Gary=20
