Runco cl-610 projector

Likely the fan blades are dirty and out of balance. If this projector is in a dusty or smoky place you will need to clean them (or have them cleaned by a tech) often. If you are not good with electronics, I suggest taking it to a dealer. If you can get the covers off properly, you will need use a can of compressed air to carefully blow out the projector and fan blades.

The first lamp "burned out" after only half a year of use and we only used it once a week. We bought a replacemente lamp and it burned out after three weeks... Someone plugged in the projector, the lamp...

The early lamp failures are due to poor air flow or longer hours of use.
So take care to clean the filters, see that the lamp brigtness is not put too high and reduce the hours of continuous use.

I have a NEC mt1055 and the unit just had new bulb put in here and it has the power and standby light come on and the fan doesn't turn on here and the standby light is yellow and status is red

The NEC’s work on a reducing time basis, they count the hours that they have been operational and refer to this as the life of the bulb – 1600 hours. When the 1600 hours has been reached the projector shuts itself down into standby mode never to be restarted even after changing the bulb / filters. This is because the unit needs to be reset, which needs to be done as follows (not included in any of the bulb replacement instructions):-
  • Plug Projector in so it is in standby mode – Orange light lit, Red status light lit (not flashing)
  • Using the remote control, hold down the power off button for 30-45 seconds
  • This will reset the status button, removing the red light
  • Power up the projector and select Menu
  • Select Projector Options
  • Select Set-up – a number of tabs will appear called pages
  • Arrow across the pages (MT850 is Page 5) until an option called “RESET LAMP HOURS” is shown
  • Move onto this option and press enter on the projector itself, confirm that you want to reset the counter
  • Projector is now back to life

This works for all NEC projectors, the page number may be different though where the “RESET LAMP HOURS” option resides.

Lines on screen

It's probably the DLP unit (or control circuit).

Of course, if you state the make and model#, we can rule out it being a LCD projector.

AND because it's worded more like an LCD symptom it's *almost* certainly the LCD. (or definately electrons not arriving inside it)

Lamp hour reset

I don't thing that because you were not reset the time lamp used now your LCD projector stop function
What was exact the unit did? no power at all or some LED light up or flashing. In any case to reset the lamp time use you must enter when unit is on
As you mentioned you did replaced the new lamp, You should check again if you reinstalled properly the lamp and lamp cover because under the lamp cover it had a safety switch if this SW not active then the unit will be in protection mode
I sugges you to remove again the lamp and reinsert properly and secure the lamp cover and try it again and if it still is not go then let me know what are the status of the 2 LED

Lamp resistance and voltage

1. Projector lamps use customized ballasts that ignite the lamp by charging it with a higher voltage in the ignition phase and then dropping down to a lower running voltage once the circuit is created.

2. Projector lamps CANNOT be tested with an AMP or OHM meter. Projector lamps function by igniting ultra-high pressurized mercury vapor across an ARC tube. At the point where the mercury vapor resides there is no conductive electrical material and therefore testing a projector lamp with an AMP or OHM will not work.
