My screen is pink, but im using Kramer TP-121 Transmitters and while is connected directly to projector shows good image, but when i connect to kramer image turns pink or yellow. Does that means that my transmitters are broken? I changed all cables twice and no luck.

If your Kramer unit is the only difference between having a good looking image and a poor image, than I would expect that is your issue. If you have used this unit for a while then it may have just started acting up.

You said you replaced all the cables between the Kramer units... INCLUDING THE CAT 5?

The cat-5e cable carries all the colors individually and if I were to guess, one of the connection points may be failing. The cat-5 should be reterminated before you throw those units out. You can test by moving the transmitter closer to the receiver and testing with a shorter cat-5 cable to see if this corrects the issue.

Yes, sometimes interconnects do fail, but it is more typical of long-haul video over cat-5 for one of the connection pins on the cat-5 itself to lose functionality.

Hi there.Well.. i have this LGPB60G small dlp led projector. Few months after warr?nty ends projectors start showing yellow tint instead of white in all screen.Looks like the blue color didn't mix well to show white color.But not sure what kind of technology is used to mix colors, three separate led lamps or ...something else.Is it possible to be repaired if yes ,is it worth it.Thank you,

Almost no projector under $2,000 is worth having repaired outside of warranty, and this one is well under $1,000. LED based DLP technology, if I have it right, uses 3 LED diodes, red, green, and blue, on a single chip. This means, when you lose one color, in any form, you are losing the entire light engine. A complete light engine replacement may be feasible, but you would really want to tackle it yourself, and it wouldn't be something I would be comfortable with doing (personally), but I can't speak for your comfort level.

I also have no idea where you would be able to pick up the specific replacement LED light engine that you would need.

I am thinking of getting a Panasonic PT AR100U as my old Panasonic has the yellow "burn-in". Does anyone know of the AR100U has inorganic lenses or not?
