As all the posts on here I have the same problem. My panasonic pt-lb10u turns on, green light flashes, fan comes on. Then the green light turns red and the red lamp indicator light comes on. No light emits...


If your projector won't fire up then you can't reset the lamp counter so that is not the problem.

The combination of LEDs you have given does not correspond to an error message. There should be two LEDs, one of which is the Lamp Indicator, and the other is the Temp Indicator.

It's possible that an overheating problem has caused this. Make sure the projector is in an area where the temprature is between 0 °C (32 °F) and 40 °C (104 °F) and the humidity is between 20% and 80% (with no condensation). It shopuld have unobstructed air flow around it.

Disconnect the power. Remove the lamp and place it aside. Clean the air filters, using a hoover, being careful not to damage the filter which is located on the underside at the front of the projector under a flap.

Carefully reinstall the lamp (when you say you replaced the lamp, did you buy a new PANASONIC lamp from a reputable source?) Try to fire up the projector. Note down any combination of LEDs if the projector doesn't work and post hem back here.

My panasonic PTLB60NTE shuts down after couple of minutes when I use wireless mode. How can I solve this?

There is three indicators lights on the panel
1. lamp indicator.
2. temperature indicator.
3. computer input indicator.

If your projector shutdown itself without given any indication its mean that your projector function POWER OFF TIMER is on. You can off this function.
How: (two keys back side of projector one is menu second is a joystick witch have 4 arrow keys and center press is enter)

press MENU button to display the menu screen and then use joystick UP or DOWN to select the OPTION menu. press joystick to ENTER and then use joystick UP or DOWN to select POWER OFF TIMER use joystick RIGHT or LEFT to select DISABLE then press MENU two times to exit the menu.

If your projector shutdown itself with given any indication then

If LAMP INDICATOR flashing RED then lamp circuit failure its need to be repair or replace.
If TEMP INDICATOR flashing RED then the temperature inside and /or outside the projector is abnormally high.

CAUSE: The ventilation opening are covered. The room temperature is too high. The projector is located at high elevations (above 1400m)
REMEDY:clean the air filter. Remove the object from the ventilation openings or clear around the projector. Set the HIGHLAND option to ON

The projector turned itself off after couple hours of use and the Temp. red light came on. Power Light turned red instead of orange as usual. After 3hrs I turned it back on, cleaned the dust off the fan...

There are three temp sensor inside the projector and now your projector need full service but if the air filter becomes clogged with dust, the internal temperature of the projector will rise, the TEMP indicator will illuminate and the projector's power will turn off (the TEMP indicator will flash after the power is turned off) The air filter should be cleaned every 100 hours of use.
If you clean the filter with a vacuum cleaner to clean off any accumulated dust. then your projector working normally

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

After a few seconds the lamp light began to blink red, its a panasonic pt-lb10svu, show no pic at all has a new lamp

Hi, Replacing the lamp in a Sharp LCD projector requires the lamp indicator to be reset. When the lamp needs to be replaced, the indicator becomes red. Resetting the counter for the lamp hours to zero will also reset the indicator to green.
  • Attach the power cord to the projector and plug it into an electrical outlet.
  • Step 2Locate the buttons on the top of the projector and simultaneously hold down the "Enter", "Menu" and "down arrow" buttons, then press the "Standby/On" button.
  • Step 3Continue holding all four buttons depressed until the lamp indicator light begins flashing green.The counter is now reset. Zero hours will now be displayed on the screen.

    if the lamp warning light is flashing, this indicates a defective ballast (lamp power module). if the lamp warning light is lit steadily, then the lamp would be at fault.
