I've started a thread on the Philips support forum for this TV (well the 58pfl9955) at,
[Link: supportforum.philips.com]Philips were very helpful and provided the initial codes I requested but then have gone quiet and despite a request for a full list of IR codes for the TV they have not yet responded. It might be worth posting over on that forum though as the more requests there are the more likely I assume they will be to respond :)
