Hitachi CP-WU5500 - key-lock on projector keys and remote causes a Not Available message when you press a key. How do you reset these issues?

Hi there

Check if both your filter timer and lamp timer is reset.

If it is then there is a Mainboard fault and it will need repair or replacement.

Hi there

In your Menu options there is a subfolder where it either reads lamp or lamp timer.

Scroll down to it and hold down you right or left arrow key on the Projector for a couple of seconds.

If you do not have a remote here is how to reset the filter time. Use the "Menu" bottun to get the "easy menu" to display. Push the down arrow until you get to "Filter Time," then push and hold the RIGHT arrow to reset the filter time. DO NOT try to reset using the "Reset" option on the easy menu, it will not work.

What you want to do is go to the advanced menu, find the filter time and using the remote hold down reset button for 3 seconds or so while the filter time is selected. This will bring up a reset menu and reset the timer.

Hiya there, just worked out how to reset the filter timer so for those that need to know here's the solution;
Bring up the menu and go right the way down to "Option" where it shows you the lamp and filter hours.
Next highlight/select the filter timer section and while its on there hold the RESET button on the remote for 5 seconds.. this then pops up with a resert option and hey, 0h again, good as new! :-)
Oh and if you dont have a remote, just hold the right arrow button instead for 5 seconds in place of the reset and follow instructions as above!
Hope this helps.
