Question about Dwin TransVision 3 Plus Multimedia Projector

1 Answer

Video then Black

I have a Dwin Transvision 3. While viewing video from any video source (cable or DVD) the projector light goes out, however, the projector keeps running. The only way to get video back is to turn off the projector, let it cycle down completely, then turn the projector back on. First it flashes green or blue, then goes out. This may happen 5 times in 10 minutes, or only once in an hour. DWIN has requested I send it back (no longer under warrantly) and they want big bucks just to look at it...any suggestions... Thank You -

Replacment of bulb on dwin transvision 3 plus ceiling mounted

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.

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.

it's time to clean it out. the colorwheel might be going and if it doesn't spin to keep in sync with the dmd chip, the lamp goes out.

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.
