Red power, blinking red temp


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.

I own a panasonic pt-ae900e i have notice a thin uneven green transpairant line in the middle of the screen lamp time 1987 hrs

There is three LCD (liquid crystal display) in your projector when one LCD faulty he display a line some time flickering line one or two lines. Due to other two LCD is working well so this line is looking transparent. If BLUE LCD faulty than the line color is very light green or yellow.

Second option is this that your projector lamp life is near to end and after 2000 hours projector is very dirty inside and need service.
(service of LCDs and other parts of projector is a very technical job and I don't know you can do it or not)

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

Half inch crystal/ solid white vertical line on screen

Adjust the horizontal in the menu then try the overscan adjustment. If the image does not look dim you do not need a lamp.

Projector shuts off within 30 seconds of power on

is the led lit on the top of the projector? what colors?

green is ok.

red flashing in sequence:
2 times- lamp hours exceed 200 hrs. replace lamp.
3 times- lamp failure. replace lamp.
4 times- fans not working. remove obstruction or replace fan.
5 times- temp too high. clean thoroughly.
solid red- undiagnosed error by projector. possible power supply or ballast.

also make sure the lamp door switch is working.
