Try ASDA first, I recently bought a 'masterplug' replacement remote control for less than a fiver. All you have to do is aim it at the TV and put in a four digit code until you find one that is right for your TV. My own Matsui was only about 10 years old and some of the buttons were worn out and this remote was perfect. It has a choice of about 18 different 4 digit codes for Matsui so I'm sure you'll find one that is right for your TV and it is cheap.
