Question about Hitachi Cine Master PJ-TX200 Multimedia Projector
Hi, i hope you can help. Last night the bulb on my PJ finally gave up and when it went out i heard a click from the unit. Now, when i switch it on it get a solid red lamp and power light and no indication that the fans are turning. I am told that this problem will not be fixed by replacing the bulb. any ideas or comments ?
thanks in advance

Try checking if all the fans are working when you swich on the unit. Normally a static red temp. light is a faulty fan that will have to be replaced.

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.

Sounds like bulb to me best way to check is take it to a service centere and they will use a replacement or test bulb to find out for you , it may not be your bulb it may be your ballast circuit . ... regards Vortash
