Re: green backround on the image

My projector is not a Hitachi but I think the menus are similar. You might try finding "signal" under "setup" in your menu and check to see if it is on or off. You want it "on". I hope this helps.

I have the same problem with my pjtx100 after changing the lamp at 2000 hrs @$450 THE SCREEN STARTED to go blue at just over 2years use sent it back to the supplier who happen to be sony dealers they said...


Unfortunately, the value of projectors drop quickly after the production run ends. You will most likely find that the price of the blue prism will be higher than a comparibe working projector of the same model on ebay. I have a Panasonic PT-AE 900U, 1100 lumens 720P 5500 contrast. To replace the main board (if you can find it) cost over $700 from a supplier. The same projector used are going for $300 - $500 in working condition on ebay. I just bought another one and it gets a great picture plus I have a second bulb as a backup with a few hundred hours left on it. I still haven't thrown away the ailing projector in hopes of someday finding a cheap one for sale with a good mainboard and a problem else where. Now I can afford to wait for one to become available.

Hope this helps,

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.

Green screen projection

This is the exact same issue as I described for an Epson user. So I'll repeat it here.

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the green color has gone out. The image is made up of red, green and blue images layered upon the screen. If the green panel has gone out then there is nothing filtering out the green light in the image. This causes a nice green hue to the whole screen.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

Image on screen is upside down

The orientation of your projector can be setup from the "Option" menu. You may need to select the "FRONT" and "CEILING" options to display the correct orientation of the image.

I have the CP-X275W that did the same thing. The ballast was bad and I fixed it with a $5 switching regulator. The CP-X327 has the identical ballast.


The High Intensity Discharge Metal Halide lamp suddenly failed to light up. A new lamp was installed and would not light up either. The fan ran and the lamp LED flashed after a few minutes. Voltage to the ballast module was 368VDC. The ballast did not pulse.

Ballast# PS-226-LS-210 was bad. Hitachi Part# HA01101 has been discontinued and the new part number is HA01102. It was $210USD at Vance Baldwin or $221USD at Part Solver.

The FET series (TR1,5,6,7,8,) seemed good: (drain-source resistance=5Kohm). Bought an identical projector on Ebay to do comparative multimeter measurements. Found resistance differences in IC01 (STRG6153). Swapped good part to bad projector, and it worked. This is a 5-pin Sanken brand switching regulator, US$5 at They have the STRTG6153, which is compatible, and may be better. The bad one removed from the circuit measures 15Kohm on pin 3 to pin 5 and the same 15Kohm when the probes are reversed. The good one measures 18Mohm and infinite when the probes are reversed.

If you would like me to fix it for you and clean all your optics, I can do it for $150USD plus $25 return shipping. Contact Chris at

If you have a new lamp for sale I would buy one for $100USD.

Good luck.

There is no picture

just a shot in the dark. this reminds me 'bout a problem with a Optoma (or maybe it was a Ask) i fixed. In that setup menu (on the proj), i was able to adjust the sync signal on the input. (I don't mean the the screen refresh rate..)  Just tried gradually step by step. Worked then!
