you need to replace power supply, it will be ok.
you can send me your old power supply photos, perhaps i have same parts,

Did you reset the lamp hours in the menu? I believe it checks lamp life by how many hours it has been used.

Sounds like bulb to me best way to check is take it to a service centere and they will use a replacement or test bulb to find out for you , it may not be your bulb it may be your ballast circuit . ... regards Vortash

Most problems with the lamps are covered in the manuels for these projectors , however none user technical difficulties are not .. ie where it is needed to open the unit not recomended to the untrained as a screwdiver in the wrong place can cause irepairable harm let alone death ?
To check if it is your bulb simply take the unit to an engineer for an estimate usually free at least you will know whats wrong and can go from there .. and if you do have a working bulb an ebay replacement is probably the cheaper conclusion to your problem ... regards Vortash
