My uncle was told that it would cost £250 to repair as it needed a new lamp driver. He has given it to me, so if I can get it going it's mine. I have opened ir up and don't think it's the driver card as sitting on the top is a board with some very melted components (surface-mounted caps and diodes). I can replace these, but don't know what their values are as they are so badly melted.
If anyone has opened of these up, or has a circuit diagram I'll be very interested to know the values of the components. I can send a digital image of the damage to anyone who may be able to help.
Thanks in advance

if you are talking about the ribbon connection on the rear of the main board, then yes I would scrap it unless you want to try and find a LP70 on E-bay to use for parts. You may or may not get a good board but if the price is under 50 bucks it may be worth the risk.
if you hear a high-pitched whir, the problem is either the ballast or the lamp. if you don't, it's the colorwheel. you could try to get the parts from an infocus service center or send it in to them for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com
if you don't hear a high-pitched whir, the colorwheel needs to be replaced. if you do, it's either the lamp or ballast. if the lamp is new, replace the ballast. you can get the parts if you want to do it yourself, or you'll have to send it in. either way, try av solutions in ny. they are an infocus service center and they're really good. www.avsolutionsny.com
try resetting the settings to factory default through the menu. if there's still a problem, take the cover off. if you look from the back of the machine, inside on the bottom left, you'll see the main board attached by a large white plug. use something thin and non-metalic to push the bottom of the board towards the plug to tighten it. now do the same to the other side of the plug. this should solve it. if it doesn't, you need to replace the main board.
in order for the lamp to strike and stay on, the fans and the colorwheel must be spinning and up to speed. if you remove the lamp and start it up, see if the 2 fans are spinning. and look inside to see if the colorwheel (a colored glass disk) is spinning. you'll also be able to hear a high-pitched squeal coming from it. unfortunately, you'll need to take it in to a repair center to have them replaced.
A tinted image (whether green or another color) is almost always a symptom of a bad or damaged cable - or a loos cable connection. In your case, you'll likely need a new M1 to VGA cable (Part# SP-DVI-A-R).
Assuming that you've made sure that the cable connections are solid at both ends, there is a simple test to verify that this is a cable issue and not a costly projector issue. While the image is tinted green, open the menu. If the menu colors appear fine while the rest of the image is still tinted green it's the cable.
