Hitachi TV and Silver Remote Codes
 

I have a silver remote and an Hitachi C2842N TV. The only problem is all the codes do not work, i have been through the whole list on their website and are going through them on the tv help and support now. nothing yet to be honest. only these codes came anything close to working which was 0065, 0527, 0540 and 0547... volume down displayed teletext, volume up took teletext off, mute was mute.
