Where do i get RPTV bulbs from? (Tosh 42WH18b), are there online traiders for them? Its got a little screen burn (girlfriend + QVC). The TVs 3 years old so may be time its for some new bulbs? or should i just get a new TV. This Tosh cost about £1300 but i know you can pick them up for half that now. maybe time for a plasma!!
