Question about Toshiba TLP B2 Ultra Multimedia Projector
I have this model and the lamp comes on and works when the machine is first turned on but later the lamp goes off even though the power is still on - does this mean the lamp needs replacing even though it still works for the first few seconds?
SOURCE: I have a model and
First of all check the lamp hour . Reset the lamp hour and try again. It is recommended that reset lamp hour only after replacing the lamp. No matter, just reset the lamp hour. If problem doen't repeat the try to replace lamp.
Another possible problem is the faulty lamp cooling fan. Check the lamp cooling fan of your projector. maybe its has some problem.Do one thing, Remove the fan from the projector. In the fan there will be a specification sticker. Remove the sicker. now u can see a hole in the center. its the bearing part of the fan. put one drop of oil in it. u can use any type of lubricating oil. rotate the fan leafs with finger for some time. after that re-stick the spec sticker. insert the fan in the projector.

I don't think this is a bulb problem I think it is a power supply problem. The power supply has converted from the line power level to what the bulb needs. If it has a problem it will go into standby. The bulb is the big power draw on these units so the parts in the bulb power section is subject to a lot more heating and such.
With 700 hours I'm not sure how old the unit is. If you have warranty this is covered. You may have extended store if they talked you into it. Or it is possible you have Toshiba warranty. You should start with the store first and see if there is warranty and they will be able to tell you if there is a local repair depot.
A Toshiba repair depot will be able to fix the unit and tell you about the repair cost. Make sure you have an idea of replacement cost just in case the repair is too expensive. Other than the repair shop I can't suggest anything that would help you out.
