Question about Hitachi PJ-TX10 Multimedia Projector

1 Answer

Our PJ-TX10 projector is turning itself off

Our PJ-TX10 projector is 3 1/2 yeras old and the lamp life so far is 890 hours. The machine turns itself off after about 40 minutes and the flashing warning lights suggest the fan is not operating and it is overheating even though it sounds and feels as though the fan is still blowing. Any ideas what the solution is?

First, to rule out true overheating, clean any dust filters and air-access areas. There might be enough dust on the filter to cause a gradual build-up of heat which could trip one of the temperature sensors in the unit. I clean my projector once a week--There might be a cooling fan going bad--after a while, heat causes the fan motor to start to drag and slows down the air flow. Also, there might be a temp sensor that is shutting down the unit prematurely.--Rick

Where is the air filter on the Hitachi pj-tx10? I dont know how it looks?


it's on the right hand side of the projector when you are looking at the projector from the front. The plastic grille just unclips and the filter is inside.

Blue spot on screen


there are light filters at each of the 3 lcd panels in the optical engine with a coating on them that determine the color. one of them (most likely the blue) is burnt from the heat and needs replacement. it could also be the fly-eye lens (whick evenly distribute the light) has burned as well. either way, it's very involved to replace, if you can get the parts. it's easier to have it sent in to get repaired.

check the wireing in the new bulb . My new one had the wires in the wrong holes like if there are 4 slots in the connector then my orignal was in slots 1 and 4 the new one was in slots 1 and 3 so I took the wire out and put it in the #4 slot and put it in and unpluged the machine and did a reset and restart and it came on green. Hope this helps.

PJ-TX100 Projector won´t start up out of Stand-By


Hi Mario

If there is no response on the Projector it normally means that the Mainboard is faulty.

Check if your machine is still under warranty because this quite expensive to replace.

As far as the schematics are concerned - I'm unfortunately not able to help you out with that.
