Volumn increases randomly and wont turn down without tilting tv

Sounds like the main switch on the volume has come lose and is making the volume switch put sound up. take the switch out of the tv and cut out the switch, (square part with the metal button) clean the board were the switch is with some warm water on a cotton bud. put the top part back on and with some sellotape stick it over the hole part that you cut out. should be fine then. if it is the square button type soldered to the board just replace with a new one. they don't cost a lot to buy take the old one with you to maplins and they will get you a replacment.
