Red doesn't seem to be working properly, but doesn't appear to be a bad projector.


The red CRT tube is failing. They are rated at 3000 hrs of operation. Check the red CRT face to see if there is a lot of dirt on it or has a discoloration on the inside of the coolant chamber. These tubes are scarce and expensive. You may want to consider a new TV.

Hitachi projector cp-s318 and the pictures give off a red tint.


Hi,

Make sure the Computer Input is set to VGA, Computer, or RGB (depending on which projector model you have). Go through the menu settings of your projector.

Hope this helps

Picture has a yellow tint. It's from an old video game that ran over 12 hours a day. Has new bulb. Except for the yellow, works fine.


Hello there:
The best way to describe this is what is called screen burn in.
this is very common on screns that have games or pictures that arre displayed for long periods of time without being shut down just like on a computer screen when a screen saver is not used .
there is nothing wrong with the bulb.
the yellow that you are seeing is actually burned into the glass part of the projector and the lense
so if you can and feel like you can dissasemble the projector dissassemble it and locate the glass and see if you can get the yellow tint that will be on the glass and the lense off by using some rubbing alcohol and a cottomn swab
But if it wont come off you will have to replace the lense and the glass ok
Hope this is very helpful for you
Best regards Michael

Hi I have a Hitachi 50v720 and I just replaced the bulb with the Phillips UX21517 bulb. When I turned the tv back on the picture worked fine except everything has a yellow tint.


I don't know if this set is a DLP or not, if it is, it could be your light engine. Not good, mine had a yellow halo about 2in thick in the middle of the screen. Light engine had to be replaced. Hope this is helpful. GOOD LUCK!

Projection has yellow tint


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.

I have a yellowish tint in the center of picture


Why does my picture appear yellowish on the screen? I haven't changed the bulb in at least 2 years. Does this make a difference?
