yellowish projector image repair

hello everyone! I just bought a 2nd hand projector over the internet. after a while I noticed that the image is yellowish so I started configuring the color control etc. but projected image was still the same.

are there any repair shops for projectors in the berner oberland zone? or maybe a shop in other areas of country that I can send the projector to to have it fixed.

fyi I have a mitsubishi lvp-x390u

thanks in advance

Re: yellowish projector image repair

the good news is that you can probably fix this with a new bulb. The bad news is of course that your bulb will probably cost more than you paid for the projector.

Yup, new bulb time. It won't be cheap.

It can also be that if you are using component cable that it is only the red and green signal go through and not the blue...either the cable or the connection on the projector could be faulty.
Just a guess..using my little experience on projectors.

Re: yellowish projector image repair

I have had this problem and it was the cable. Which cable are you using? s-video? Component?

Check the cables and connections before you buy a new bulb. Also, check to see if your projector gives you an estimation on how much bulb time remains.

Re: yellowish projector image repair

holy crap! that is one expensive bulb!

I bought a new Scart plug <-> 3 RCA plugs cable from interdiscount. I tried both video jacks and it was still the same so yeah it MIGHT be the bulb. but I'll go to back to interdiscount if I get the chance to see if I can get the cable replaced. hopefully that would fix it. btw, I checked ebay international and found a bulb that would cost me $230 including shipping but hopefully I won't have to get it.

thanks a lot!

I'll let you guys know if i got it fixed

Re: yellowish projector image repair

Like a post earlier, could be one of the colours (Red, Green or Blue). I'd start by trying to connect with a different type of cable. So at the moment, you're connecting the colours individually via component. Try the Composite input (which is a single photo/RCA socket normally coloured yellow)--your digital camera or DVD player may have a composite out. If you still have the same issue, then I'd say it's something inside...

Maybe could be a dry joint regarding the circuitry where the colour signals are transmitted. These things do get very hot and something like a dry joint is possible.
