DVOM like you could a incadecent lamp? I have a Viewsonic PJ500 I bought used the power light and the lamp light are both red. The lamp looks good but tests open with a dvom can you test these lamps with a DVOM?. I have also tested the power to the lamp and it is only .04v which is low assuming I am testing it right.I hate to buy a lamp if it doesn't need one. Any help is appreciated.
