NEC Projector clock reset

[Russ Peck]

Any ideas to reset a lamp clock for a NEC MT1056 projector. Got it on eBay
with no remote and it would seem no way to reset the lamp clock without it.
Thanks
Russ

Russ,

I don't know your model of projector, but from the one I just had to
change in my Father's NEC, I would not reset the time without replacing
the bulb. When I inspected the old lamp, The reflector coating was
beginning to separate from the glass, and looked 'wrinkly'. These bulbs
contain mercury, so if you run it until it blows and it shatters,you can
basically throw out the projector. Also, if the bulb fails, it might
take its power supply with it.

However, ant least on the LT-240K, you still have to reset the lamp
time with the on screen displays, which will require the remote if the
unit does not have redundant controls on it.

P.S. Yes, I know all to well that these lamps are expensive.

I had a boxlight CP-7T that the same thing happened. lamp exploaded in it.
and the ballast was NLA.

So, i just rebuilt the ballast. the transformer was ok, just the H-bridge
that drove it was shorted. replaced it, along with the fusable resistors,
worked like a brand new one

Thanks Tim,
I did replace the lamp with a new one. Left that out of my post.

Russ,
I don't have info for that model, but earlier and later models as follows:
For NEC MT1040 & 1045, if the old lamp time exceeded max hours, the projector
will not come on with a new lamp installed and the projector remains in
"standby" mode. In that mode, press and hold OFF or HELP button for 10 seconds
minimum. The STATUS indicator should go out and the projector should turn on
normally with the lamp counter reset to zero. Nodels MT1060 and later have an
EEPROM on the lamp housing that will not allow more than the max hours. Changing
the lamp automatically resets the counter. Yours might respond to the earlier
command... worth a try.
