Toshiba TV and all in one remote
 

Hi everybody
getting really annoyed at the minute,
I have a Toshiba TV (1752TB according to the back of it) and purchased a Masterplug TVRC4N 4 in 1 remote control.
However i can not get the two items to work together.
I have entered all the codes for Toshiba - no joy. tried the codes for Phillips and Bush as well- still no good. There is no automatic scan on the remote, but a manual scan by entering 991 all the time, but after trying it for several hours :( ...well you all probably know already.The Remote works on the cable box and video player.

Can anybody provide any additional help?
