It is fairly simple. Take the unit down as you need to get to the underside. There you will see the retaining screws that hold the cover on. Remove these and open the unit. Inside you will see the bulb and mounting bracket. Off hand I don't remember exactly how it is held in place but there are a number of screws and a lead to disconnect to remove it.

I have a Dwin TransVision 4 that is not working. It started out with us being able to watch a movie for about an hour and the bulb shutting down. I finally ordered a bulb from Dwin (at 458.00!!) and...


honestly it sounds as if a capasitor is overheating and once it overheats the machine is shutting off.... I myself would be able to look at it and see if this was correct or not. i am not sure how familliar you are with these types of things, probably best to take it in and tell them exactly what is wrong...

Dwin transvision 4 projector lamp will not light even after changing the bulb. It also looks like Dwin went out of business. Any options to fix?


Call Interlight @ 219-989-0060 and read them what the part # is on the bulb inside the cage. They can probably supply you with the lamp and you simply reuse your cage.

They were able to do this for me

Projector turns on but no light or image from lens.


The bulbs do not always look broken when dead. You say it is used often. The life of a bulb is around 1400 hours I believe. This normally equates to a year or two depending on your usage levels. Did you notice your image getting dimmer in the months before it stopped working? This would be a good sign it was in need of replacement. Are the lights flashing very rapidly or blinking slowly? If they are flashing very rapidly this indicated the bulb will not fire and needs replacing.

Dwin Trans 3 Shadowing at Edge


you'd need to remove the top from the projector. the light tunnel is between the colorwheel and the lens assembly. remove the metal frame from it. chances are it's falling apart. since the company's out of business, finding a part is an exercise in futility. time to trade up.

Dwin lamp turns off


I design and implement switching power supplies for the commercial lighting industry. I also own a DWiN Transvision and have opened it and worked on it several times. I believe I can answer this question.

The DWIN projectors use a proprietary switching power supply to strike the lamp and keep it burning. The power supply is extremely sophisticated and maintains tight voltage and current tolerances. This is important because the halides in the lamp are damaged by power supply fluctuations. The halides can often be seen in an unfired lamp, they appear as small specks of dirt or tiny beads inside the lamp envelope. When a metal halide lamp is struck, the halides (which are rare earth elements) vaporize and cling to the inner wall of the lamp envelope. The mixture of halide gas in the lamp is what determines the color temperature of the lamp, as well as the accuracy of the lamp across the entire color spectrum.

One of the ways that DWIN is able to deliver such great color is because they use a lamp which delivers this great color across the spectrum, but, as I pointed out earlier, can be damaged by fluctuations.

The power supply contains three switching sections and five references for such things as input and output voltage for each psu section, as well as overcurrent demands from the lamp.

From my experience, your lamp(s) are all exhibiting issues that require replacement.
