I bought a Toshiba 51" (model no 51WH36P) RP tv six months ago. I am very happy with it but I knew nothing about RP when I bought it and recently I have started to worry about the high cost of repair/replacement if it goes wrong. I assume this model has three bulbs, one for each primary colour, does anyone know how much a replacement costs and how long a bulb can reasonably be expected to last? Where can I get the bulbs, just from Toshiba? Can I fit them myself or does an engineer have to do it? Will it cost an absolute fortune when this happens? I am so worried about "wearing it out" that I have brought a portable TV into the living room for watching the news or whatever and keeping the big TV for watching films. Actually I may just sell it as it's a bit too big for the room really.
