The problem is that you are missing one of the primary colors. This can be caused by a couple of things. It could be the cable or the input port on the projector (pin bent or missing)

We have used our projector for years, but are now having a problem with the picture. The picture that shows on the screen is shown in a red/purple hue. Any suggestion on how to fix?


Hi,

Are you using component video inputs? You could check the green connectors on both ends of the video inputs. They sometimes develop a poor connection. I would not throw a lot of money at it. It was a good projector in its day but they sell used on ebay or craigslist for $100 - $300 now.

Hope this helps,

The projector would not turn on and had a flashing red light for the lamp. Knowing it was an older projector when we rented the building I purchased a new bulb for this projector. When I put the new bulb...


PROBLEM :-The power supply of the projector is faulty there is a transistor witch is switch 15 volts for the lamp drive board.

SOLUTION: Remove the upper cover with 6 screws back side of the projector.
remove main board and lamp cover with 7 screws.(show in the picture)
remove upper cover of the power supply and lamp drive unit with 3 screws.
remove power supply unit with 4 screws and 3 connectors and put face down on the table.
now you find the transistor no Q107 and replace with the transistor no 2SB710 is and surface mounted compunent(show in the picture)
fix it all as you open.
power ON the projector and enjoy

(doing very carefully This is a technical job)

My video yellow plug works fine, showing correct video colors yet, the red blue green connection is only showing picture in a pale green


Yellow is composite input if RGB is not working it's probably a cable/output problem try with a different device first.

Abnormal picture


if it's an xr-32x (as it shows on this pic), it's a dlp projector, not an lcd. therefore no green filter. it has only a colorwheel and a dmd chip to affect the color. if it's not an xr-32x, and it's an lcd projector, replace the green filter. sharp sells the parts for the optical engine. but if it was your service tech that did it, have them replace it.

Abnomal reverse picture


if it was the fault of the technician, they are responsible for the repair. if the green filter is bad, it needs replacing.

Connection Identification, experiencing no Sound


Thank you for your help I visited a Sony retail outlet yesterday and they explained that to obtain sound you have to go through a sound system using the red connection because they is no sound / speakers build into the projector.
