What lamp do i need for a mitsubishi model vs-7087 projector big screen television

Hello there. It's a bit of a strange question to ask. But I would first check the lamp umber printed on the lamp. I am sure there is a printed number on it. Secondly I would return the lamp to a TV retailer and purchase or order a new lamp. But if this is too much for you, you can get a lamp from the internet at possibly half the price, delivered, on Amazon and EBay. Here are a few links to try. Hope it's not too much for you but it's worth a try. Cheers.
