My blues are green on my projector. do I need a new bulb?

If this projector is connected by Component Video (3 or 5 wires) instead of HDMI, the most common color related problems are caused by having one of the 3 video cables (Red, Blue or Green) with a bad connector. If everyone is a green smurf the problem is with the red cable. If everyone is a red smurf the problem is the blue cable. If the green was bad you wouldn't see anything.
Another possibility is if the green is plugged into the yellow jack instead of green jack on the projector, you could see what you are describing.
If everything checks out, take the projector to a repair facility.
If you are connected by an HDMI cable, (combined with the fact you mentioned vertical lines not horizontal) then take the projector to a repair facility.
All of this assumes that you don't just have a bad Cable Box or Blu-ray player or Home Theater Receiver. (The source)

try to check dlp chip inside the projector maybe dlp chip got problem or very dirty or check whether color wheel got fungus and try to clean it.

You will probably need a new lamp.

Depending on how severe it is, it can be fixed. I can do the repair if you'd like.

From your description, it sounds like a problem with the blue color. Green LCD=purple onscreen, Red=cyan(baby blue) onscreen, Blue LCD=yellow onscreen. It could be a lot of dust on the blue lcd panel, or worse, might be a burned polarizer filter behind the lcd panel due to excessive heat. If you can focus on the yellow and its tons of yellow specs, its dust. A burned filter however, must be replaced. A technician trained in projectors will have to do it. The filter material is glued to a thin glass panel and is replaced as a single filter. It's a very involved repair.

its not the bulb problem . the lcd block need sto be replaced , better to buy new projector

Hi - You can download the manual by clicking the link underlined in blue below:

Most likely the air filter needs cleaning. See page 55

Hi terry2421

No this is not the bulb. You will have to get the Mainboard repaired at a service provider. Losing signal and a discolouration showing up is a clear indication of a faulty Mainboard.

Get a quote first , because some service providers overcharge on these sort of repairs. The most you should pay is $150.

you have to replace prism it has 3 small lcd screens Green Red Blue one of them is beginning to burn they are very expensive strip projector down with no power connected and take damaged screen of then block that area so no light can pass through it with fire resistent material you will get some more life out of it
