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.
Details:
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 www.electronix.com. 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 [email protected].
If you have a new lamp for sale I would buy one for $100USD.
Good luck.
Another tech reported that it was the main board, not the ballast, that was bad. The board was sensing a false lamp overheat condition. They were able to locate and replace an electronic component, then the projector worked.
Hi Chris,
Â
Got the parts and replaced them, TR01 (2sk2642) was not faulty but I replaced it anyway because I broke one of the pins when I de-soldered it from the pcb.
Â
When I turned on the projector, the lamp would not start. It tried to start up repeatedly resulting in short dim flashes of the lamp, and after a few sessions the protection mode turned on with the flashing "lamp" indicator led.
Â
After that I replaced c04 c05 (both 47uf 25v) and c06 c07 (both 10uf 50v) tried again and WHAM! It works!!!! :)
Â
The parts I replaced to get the projector working again:
Â
IC01= STRG6153
R06= 6R8
R07= 6R8Â
R11= 4,7 ohms
C04= 47UF 25V
C05= 47UF 25V
C06= 10UF 50V
C07= 10UF 50V
Â
Many thanks for your help and the posting on the fixya site, without that thread I would never have come this far!

R06 and R07 this is 1/10w or 1/4w or 1/8w
Cedric, the watt rating of surface mount resistors can be determined by measuring its size. See
Cedric, see my profile for my email address. Email me, then I can send you the service manual.

I have the same problem (power light blinks red, lamp light stays red), but I bought my projector from a surplus auction.
Is there a way to see whether there is a problem with the ballast or the lamp before dropping $200 on either one?
These projectors suffer from premature ageing of the ballast psu, I carry spares for these and can repair
No, but just come across the same problem
I have the same problem? Anyone fixed it yet?

After turning on the projector, the POWER light flashes green, then the LAMP light turns red and the POWER light flashes red. No light from LAMP.
I replaced the lamp twice, but this did not fix the problem.
There is good air flow.
I have the same problem

I talked to someone at Hitachi and they said I got a bad bulb so I replaced it AGAIN Still have the problem!!!!
