Question about Hitachi CP-X327 Multimedia Projector
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 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@example.com.
If you have a new lamp for sale I would buy one for $100USD.

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
