The button is probably worn out. You will need to get a new button for it.

Fan works, light doesn't - replacing lamp doesn't help. Suspect electrical problem. Is it fixable and cost effective?

Your bulb socket has probably burned out. As far as being cost effective, that would depend on whether you could find a new socket and how much someone would charge to put it in if you were not wanting to try yourself.

I bought the Living Accents Corona Wicker Bar set the glass top shattered I dont know why but it is a million pieces, can I order another one through living accents

go on line and see if one is available
the glass would have been toughened glass so that there are no sharps to cause injury if broken
glass supply shops ( windows and door manufacturers ) can supply glass cut to size and then toughened
This will save on freight costs to you as you can pick up the new top locally in your vehicle

Take the lamp out and check for physical damage. Some lamps come defective and can shad (brake glass inside) upon warming up. The "pop" sound could be it.

Projecter went bang, is it bulb or fuse.

Hello. First, unplug the projector. Next, obtain some paper towels or newspaper and make a suitable work surface on a table. Then, open the lamp door and *being very careful here*, remove the lamp. Immediately check to see if the lamp has indeed blown--usually the bulb portion of the lamp pops into pieces but sometimes it breaks the cone shaped reflector. Next, flip the projector right-side up and shake out any broken glass fragments--hence the need for a disposable surface! Then, using a flashlight, CAREFULLY inspect the area in the lamp compartment where the lamp is aimed at to see whether the heat-absorbing glass or glass filters have been damaged by shrapnel at all. (When a lamp explodes, that much force is generated!) If any glass panels are cracked or pock-marked at all, the projector MUST BE REPAIRED before use. These glass panels can, of themselves, violently shatter due to the extreme heat from the lamp.
If no damage in the compartment has occurred, gently blow out any tiny glass fragments with canned air. Put in a spare lamp and see if the projector will power up--chances are it won't. There is an internal fuse normally located very near the power plug socket. It is usually a Buss glass fuse, 5-7 amps rated, but if you haven't worked on projectors before, I wouldn't suggest removing the top cover to get at it...send the unit off to be repaired...When a lamp blows like that, a lot of times it takes out the power supply section and/or the circuit that powers the lamp (ballast). If glass panels are damaged, the "optical engine" (internal framework that houses all the mirrors, lenses, and filters) must be replaced--that is very expensive--some companies are able to fix the optics without replacing the whole engine. Hope I helped you.---Rick

I heard a pop and now the projector only shows black and white.

The color wheel has failed in youtr projector. There are 4 pieces of glass in the color wheel which fit togeter in a "pie" formation and they are red, blue, yellow & clear. This wheel is spun by a motor. The glass is glued to the motor's hub, and, when it fails the glass segments are thown off the hub. This gives you a B&W picture because all of the light is allowed to shine through the optics all of the time. Replace the color wheel with Toshiba part no: 23125963. It will be about $65. No soldering is involved, just use care with the ribbon cable to the motor. You will need a no. 2 phillips screwdriver and a set of jeweles screwdrivers to do this.
