Both Temp and Lamp lights blink red

These blinks of LEDs are fault indications. If you wish to get more details about these blinking codes, check this link. The details are there. It is very difficult to include all those details in tables here by this window.

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..

Hi Charles,

Sorry for the late reply, I'm offline upon purchasing my service.
You have said that you can hear a low buzzing sound before the unit gone to subsequent shutdown and the lamp blinks green(meaning that the unit try to turn on the lamp for consecutive attempts but not generally mean that the lamp itself is faulty.) and the temp led light come on.

As a matter of fact all the information you have mentioned linked to the symptoms you've encountered right now. A low buzzing sound might be caused by faulty FAN inside the unit that trigger the error code (blinking of the standby/temp led light) and turns off the unit automatically due to thermal protection circuit.
However, the technician might be true also that the buzzing sound came from the faulty color wheel. To confirm it, you have to verify where the buzzing sound came from. Color wheel is in front of the lamp assembly. Faulty color wheel can produce the same symptoms you've encountered right now but most of the time, it shows 3 blinking led light at the front panel (Timer, Lamp, standby/Temp).

I would advice you to open the back cover of your unit, fixed the lamp door safety switch with the tape to make it in closed position( if it is on open position the unit will not power up), and then turn on the unit and observe the fans if will spin or not, and check also where the buzzing sound came from before the unit gone to shutdown.
I've suspected that the fault came from the fan based on the led light flashes. Please let me know what you will discover after following the steps above to verify where the exact fault came from. Also, let me know the exact status of the led light at the front panel, (Timer, Lamp, standby/Temp ), which of them lit solid/blinking, it will help us to narrow the caused of the symptoms.

Unfortunately, the PJD5111 is indicating that the lamp has overheated. If you wait 45 minutes for the projector to cool down and these lights still come on, then the unit has an internal failure. The failure may be in the temperature sensor or that circuit. If the projector is still under warranty or on a maintenance plan, contact the dealer.

I wish that I had better news for you.

This always happens on hitachi projectors aswell,It is just meaning that you need to clean the air vent and reset the timer and then it should be alright.

I have PJ 550 exact SAME PROBLEM replaced bulb NOTHING

Check your color wheel. There is a DIY guide for replacing the color wheel. Mine did the same thing yours is and my color wheel was all busted up. Unfortunately after replacing the color wheel my set continues to do the same thing, but this could mean I need to replace the ballast as well.

The color wheel needs replacing. Thats causing the whining and it will also make the lamp light blink.

did you try setting the lamp over the red light on the tv?

Your service manual on page 82 steps you through decoding the blinking
1) there are two lights on the front near the reciever of the remote signals (Temp indicator and Lamp Indicator)
2) If the Temp indicator is on then they recommend you contact a service center
3) If the Lamp indicator is on and the power light stays on (no blinking) then you need to replace the lamp. Otherwise it says to contact the service center.
4) Counting blinks with the lamp indicator (1 every 5sec - lamp will not light or is abnormal, 2 every 5sec - lamp voltage is abnormal, 3 every 5sec - lamp temp is too high, 4 every 5sec - other error)
