SOURCE: panasonic pt ae900 wont fire up

First , start over and unplug it. Wait a few minutes. Turn on AV system that is connected to it but not video or dvd player. With remote, point at is corectly and push power 1 sec or as soon as you see green light come on. Be quick.
If this fails you can wait 4 hours and repeat. OR try only projector with out any feed.

Let me know if this worked.

SOURCE: Panasonic PT-50DL54J DLP TV Flashing Light

I had the same problems that most of you have been having, tv turning on and off, lights flashing in all different colors, having to unplug tv to reset and all of that good stuff. I noticed that most of the time this would happen once the tv would start to heat up, and I could hear the fan working a little harder. Well I am not an electrician but It was very simple to unscrew the lower bottom park of the tv, where the fan and most of the electronics sit, then I used an oxygen tank ( I work for a medical company ) to blow out all the dust in the tv, ( you can olso use the compressed air use for computer, but if grandma or grampa have some O2 laying around, it works really good, LOL. )and was very surpriced to see how dusty it was, then I removed the MAIN FAN ( you only need to remove three screws, however there's a box in fron of it, which you'll have to remove first in order to get to the fan ). this may sound a little complicated, but trust me it is not, once you have taken the fan off, clean it all the way around ( best to use a clean rag, the compressed air was not doing the job.
long story short, once I cleaned the fan and put it all back together. The TV still didn't work LOL, Just kidding, It has been working perfect for a little over a week.
If I can help in any other way, please e-mail me @ gsierra11@yahoo.com

hope this helps.

Turned itself off. I turned it back on and power button blinks green for a few seconds then blinks red continuously. red light by card reader blinks red about every five seconds. No picture, no sound.


unplug it from power source completely 15 minutes then plug back in with NOTHING plugged into any of the ports. If it boots back up then does it again later it make be something plugged into a port causing power to back feed into the boards. I had this same issue on my plasma last year ended up being the xbox360. After this if it still wont power then your power board maybe bad.

My PT-D5500U will show the red light when the power is plugged in, when I turn on the other power the power light will go green for a moment and then start blinking red. No lamp comes on and the fan gets...


How many hours are on the projector? I would say that you need to change lamps first. Unfortuantely, this series of Panasonic is known for lamp and lamp circuit issues. There are runs of bad lamps...try 2 new lamps if possible or consult an authorized service center.

Good Luck

The Power Light is Red


yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on
