Degrading picture with my Dwin projector

When we first start the projector, the picture is fine. However, after a time (it was originally almost 2 hours, now the problem is starting after about an hour) the picture becomes unstable...light flashes, loss of color and clarity...starts small (very sparse, light flashes...almost not noticeable) but within about five minutes gets to the point where the flashes are constant. If we turn it off, then on again, the picture is fine for about 30 seconds before it starts acting up again. If the projector is left off overnight, then started, it's fine for an hour or so before it starts the problem again. We replaced the bulb about 700 hours ago. The projector is about two years old, and only started doing this in the past month.

The colorwheel is going bad and needs replacing. the colorwheel needs to spin fast enough to sync up with the dmd chip. if it cannot, the pic goes bad then off. the flashing is the colorwheel trying to catch up.

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 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 Trans3 Plus will not lite

I had a similar problem and it turned out to just need a good clean. The fans can pull in a lot of dust and eventually this causes intermittant starting problems/noise. I attacked mine with compressed air and a vacuum cleaner and this completely fixed the problem. Try to control where the dust goes you want to avoid just blasting it inside the unit and on the lense, bulb, etc

Picture becomes unstable after turning it on (lack of color,

The problem is with overheating!. after a few years the fans accumulate dust and "stuff" and don't work as well. Get a can of compressed air and blow out all the ports and fans. I take the cover off and with everything cool, I blow out all the internal fans also. The 3 big fans on the back are easy to remove and clean and get spinning again. Usually this fixes the issue for several months but eventually, professional cleaning may be needed at DWIN.

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.
