Red lights flashing on ViewSonic PJ750

On a ViewSonic PJ750 the "lamp" and "temp" lights both flash red in unison. The unit seems to work at least for the few minutes it was left running, but I'm afraid to leave it on too long if it if truly overheating. I can take the filter out and see that both intake fans as well as the fan on the bulb side are all spinning.

This is a sign of overheating, its a thermal issue, I solved the problem with some compressed air, but absolutely DO NOT blow in the ldc assembly or you will get dust in the lens system. You want to blow the cmpresed air on the electronics not ont he optics. I found that over time dust hair ect collected on the thermosistor and caused the over temp error. Cleaning it resolved the issue.

I turn on my Viewsonic PJD6251 but the lamp does not come on, and after a few seconds I get 2 red lights TEMP and LAMP. It is new, only 2 weeks I barely used. Good care.


sounds like a bad bulb

projectors get a resistance reading from the bulb and if it doesnt get right value it will give you the double red lights

only other thing it could be is if the fans in projector are not turning on

call viewsonic and tell them issue and make them resolve issue

or

if unit is only 2 weeks old bring it back to store and get replacement or call viewsonic and get them to send you replacement unit - it is too new to mess with it yourself and take chance on voiding warranty

Red power, blinking red temp


Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

  • A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
  • A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.
Goodluck..

After changing the bulb image will not come on and solid orange light appears


Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

TV went off, and three lights come on (green "power", red "temp", and red "lamp")for just a second, in succession from left to right.


My television had two red lights flashing, one for Temp and the other for the lamp. I removed mythe lamp assembly and the bulb filament was burnt out. I order a new lamp and housing unit UX21517 and replaced it and now I have the red light flashing which is calling out the lamp again.

Red temp and lamp light flashing


you may need to replace the lamp in the unit, to do so, remove the lamp and if it sounds like a rattle inside when you shake it, its blown due to heat ,hence the red temp and lamp warning. after replacing the lamp make sure you reset the lamp use hours. good luck.

The lamp continues to flash red lights for power and lamp


I have the same problem as posted too, ordered 3 new lamps and they all still do the same thing. I`m starting to think its the projector that has a problem. Anyone got a solution other then keep buying new lamps and try getting it to work... I mean, after 3, how bad lucky can you be that they are all bad lamps...

Projector lamp flashes and the temp red led lights.


Purchased our76C in Jan, 2007. It is our second unit now that has had the same symptoms. When the unit starts up, the Power light is steady green as normal for a few minutes, but no image is projected. After a few minutes the lights do as you described. Both times Epson support authorized a new unit to be shipped out immediately. They said they had no known issues about it and didn't indicate what was causing the problem. Apparently it is not just the lamp wither. Also, the lamps both had under 20 hours on them.
