I don't see my problem posted after paying. So I'll repost it. Have sound but no pic. Menu comes on and little channel logos appear at bottom of screen when channels are changed. 3 guns are on but not creating images. No smell of component burning. Think it may be rf converter. Can module be found and replaced or should I start troubleshooting board to component level? Thanks.

The clear bulb located back left side needed to be replaced. Too much heat causes the bulb to burn out. Simple fix. One screw to open door to bulb compartment. Two screws to remove bulb assembly. Thank goodness for extended service warranty which paid for it. This is the second one in three years. At the price of $200 for bulb and $100 for trip and labor, this is not an inexpensive fix. Anyone purchasing a projection tv should get an extended warranty.
