If both lights are flashing orange, that means that the bulb needs to be replaced and the filter needs to be cleaned. Make sure you reset the counters for both after you replace them.

hi there,
I have just done the exact same thing today. Press menu button on projector. Scroll (navigate) to the mirror option. This give you the options to mirror image left to right or up and down.
This should fix any of your problems.
Cheers
Luke

Hi there

In your Menu options there is a subfolder where it either reads lamp or lamp timer.

Scroll down to it and hold down you right or left arrow key on the Projector for a couple of seconds.

SOURCE: i have a hitachi media projector and a blue patch

it's not the prism, it's the light filter on the blue lcd panel. it's starting to fry due to dust and heat. it does need to be replaced, but most companies won't just replace a part in the optical engine, so you'll have to replace the whole optical engine. and it's pricey. but find a hitachi service center (on their website) and ask them.

I work in a school and one of the projectors has a yellow area in the centre of the projection. The lamp has been replaced ?


Your Blue LCD Light valve is burned or has dust on it which blocks the blue color.

With RGB, the absense of blue (Red + Green) is yellow.

If you're lucky a simply cleaning at the light valves will solve your problem. Otherwise your looking $$ for a new LCD valve.

Have changed the bulb because of yellow blob on the picture and it has made no difference


the yellow blob is from a fried polarizer on the blue lcd panel due to excessive dust and heat. you'll have to replace it, but hitachi doesn't sell individual optical engine parts, so you may have to replace the whole optical engine.

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.

HItach cp-s860 problem


I have the same Hitachi CP-S860 and have found the problem is with the convergence on the left and right sides of the picture. The one I am working on has a bad ghosting problem also - you can really see the ghosting when the MENU is on the screen. The center convergence is OK. Following Pics show Circle / Cross pattern - 1st pic the red, green and blue are turned on - 2nd pic shows green and blue on only. I do not have the service manual for this set so I do not know the convergence procedure on this one. I have mostly been repairing NEC, Sanyo, Panasonic and Christie LCD & DLP Projectors.
