JVC DLA-RS4800U Projector DLA-RS4800U "voltage drop" Questions

...you mean it flashes on then goes out, it could be the lamp ballast. It puts out an initial high voltage to spark/start the lamp, then drops the voltage to keep the lamp lit. It could also be the ...

...lines can be caused from excessive heat from too much dust. fans could be wearing out, causing voltage spikes and drops. also could be that the main board has an issue and needs

...to it full strength, it drops down to 40vdc to maintain. if the ballast can't get up to the proper voltage, it shuts down. or the lamp itself will not hold the voltage, and therefore needs

...Voltage is ok but the fan just sits and hums hi, do one thing. remove the fan from the projector. In the fan there will be a specification sticker. Remove the sicker. now u can see a hole in the ...

...it needs all that space... You may want to make sure the AC line voltage is 110 -120 VAC even a slight drop in this voltage will cause the projector to run less efficient which means running

...model projectors will not even try to ignite the lamp if they detect drops or fluctuation in voltage supplied to the unit. This is a safety feature to reduce stress on the lamp. PLEASE DON'T ...

...also replace it if it has bulges, black spots, fogging or flaking. when it's on it's way out, the voltage drops and that effects the light temp. if the lamp is new(ish), you may have a bad ballast. ...

...about 20vdc, but the high strike runs through a different part of the ballast than the maintenance

...the fans by hand and then they run slowly again. I conclude that the projector is producing low voltage to the fans. But I don't know how to fix it. try to change the fan.I think is fan ...

...would need a new one... Lightning strikes and near misses and power outages can create mains borne voltage spikes and surges that frequently damage sensitive electronics. These days almost
