I'm having a strange problem with my Cambridge Audio M500 (Home Logic UR362) remote. It learns eveything fine except for my Goodmans (read cheap) TV. It seems to leran the codes okay, and when you press the button it works once and then future presses don't work until you've pressed another button - does that make sense?!

For example, if I learn Channel Up and Channel Down I can make the TV go up, down, up, down fine, but if I try and do up, up, up or down, down, down, it does the first one but then ignores the other presses. Its really strange. I guess its doing some sort of cycling code or something but I can't work it out. I've tried learning the codes from an All4One remote as well and I get the same effect.

Has anyone seen this or have any ideas for solutions?

Thanks in advance

Hello Joe!

I'll get my equivalent Rotel RR-969 in a view days and will run into the same problem with my old Philips TV.

I had no problems so far because my old universal remote (TopTel5 from CME) had Philips preprogrammed. Even when I learned a code for this TV to the remote it was ok because each button had to be learned twice so all buttons got two codes. Unfortunately only one panel was programable (the other 6 preprogrammed) so the TopTel5 does not fit my requirements anymore.


Two solutions for the problem I'll try:

1) Choose 5 (with Power 6) commands you need often and learn them to the multi-code capable buttons. I don't know yet how many buttons I'll have available on the Rotel.

2) Another way (for people with some electronical skills): Build an IR sender that permanently sends a command which is recognized but has no effect to your TV when it is on. If this signal is weak enough it will be received when no signal from your remote is sent. When you use your remote this signal will be stronger than the pseudo-signal and so the TV will act correctly. The trick here is that if you press up twice it won't be twice for the TV because the pseudo-signal interrupts the sequence.

A more power saving but also more complicated way is to only send the pseudo signal for a short time after a remote signal is received. You will need a seperate remote signal detector for this purpose.


I hope my reply isn't too complicated (neither for technical reasons nor for my English)... ;-)

Ciao and bye,

Basically the problem is you have a "parity bit" or "toggle bit" code. There's some information on this site in FEATURES -> Proprietary Remote Systems.

Thanks for the info. It seems that I'm stuck with the problem. Its not a big problem, but it would have been nice to have fixed it.

Never mind!
