Question about Panasonic PT-LB50U Multimedia Projector

The projector lamp does not turn on

Hi,
I have a Panasonic PT-LB50U LCD projector. When I turn it on the bulb comes on momentarily, the power light blinks green for about a minute and then turns to blinking red and the lamp indicator comes on. I bought a new bulb and the projector has the same problem. Where can I take the projector to get it fixed or can you tell me what to do on line?

I have done this on several of our PT-LB50U's with sucess every time.Remove lamp cover and lamp.Then remove top of case by removing 6 screws on bottom.Remove metal shroud that would cover lamp 2 screws and remove 2 screws that hold lamp plug and move it away.You will see a little blue lever for saftey switch move it back and forth from top and bottom put back together and should turn on.

    A simpler approach is to remove the lamp cover off the back and poke a toothpick down the slot where the pointy bit on the underside of the cover protudes down into the machine. see if you can unstick the little blue switch this way.

How to do lamp reset on panasonic pt-lb50u projector.


To reset the lamp hours, turn on the projector. Then press Menu and use the Up/Down arrows to highlight Options. Press Enter then highlight Lamp Runtime. Press and hold Enter for 3+ seconds until the Lamp Runtime screen is displays. Press the Power button (any other button cancels the reset). When the Power button LED turns red, unplug the power cord to the projector. You can either use the remote or the controls on the projector. Reconnect the power cord after a few minutes.

The reset instructions are on page 62 of the user manual. The manual is available from Panasonic here: https://support.panasonic.co.nz/docstore/PT-LB50U%20Operating%20Instructions.pdf .

I hope this helps.

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

Unit powers on momentarily, bulb comes on for about 4 to 5 second


if a fan is blocked from turning then the power up self testing will detect a problem and stop it from further operation. thats why you have to unpug it

My Panasonic PT-LB50U LCD projector flashes red lamp indicator and will not light up. I replaced the lamp and it still will not light. The old lamp only had 20 or so hours on it and it does the same thing....


this worked for me what i did is: turn on projector then undo the light panel when its on the projector then will cut off, now the light panel pushes down on the hidden safety switch take a screw driver and push down on the switch, the projector will turn on then wait for about 8 sec then release the projector will turn off, repeat step several times until the light flickers, then do a couple more times and the light should come on and should stay steady turn off and let cool for 10 min, this worked for me hope it works for you!
