How can I turn up the volume on my Matsui 14V1R without the remote control?

I have a Matsui TV (14V1R), but no remote control. There is no control switch for the volume on the TV (that I can find). Is there a mysterious way to turn up the volume on the TV set itself?? If not, does anyone know if there is a way of getting a Philips SBC RU 430 universal remote control to work on this model of the Matsui TV. None of the codes listed in the manual for the remote control work on the TV, neither does the auto search function. I've tired contacting Philips, but they have been less than helpful!
