Answer
Lamps not specified by the manufacturer can present problems because the circuitry of the Toshiba system has filament monitoring to detect changes in age and temperature.  A generic bulb can have specifications differently than that prescribed by Toshiba.

In any event, DLP sets from all makers, including Toshiba are fraught with problems. The repair expenses for DLP sets is very high.  In fact, many owners have decided to junk them rather than keep feeding them with lamps, parts and repairs.  If the optical engine fails it could cost several hundred dollars for replacements.

I suggest you go on google or bing and search through what others are finding with your model. There are forums and repair suggestions of many kinds and conditions. You may find something that will direct you a little differently than the course you are on now.  

Hope this will help you find a solution or make a decision on what course to take.

Best wishes.
