Question about Panasonic PT-LB60U Multimedia Projector

Open Question

Briefly powers up, then shuts down.

When connected to power, status light on power switch lights up green, and unit powers up for about 5-10 seconds, then shuts off. Tried a known good bulb (we have 12 of these units), but same result. No warning lights come on during startup. Normally, when the unit is plugged in, the Power button light goes red for standby until button is pressed for start.

SOURCE: Green light flashes 7 times on power-up then turns red (off).

ya thers class action law suit on that bulb your talking about it will go out after 3 mo pp say its reall bad

I read in the various forums that frequent lamp failure can be caused by a defective ballast. I have not seen the schematices for the TV but typically a ballast controls current flow in a lamp. If I understand your post correctly it sounds like you have had a lamp failure per month for three months. I would recommend that you contact Panasonic 800-211-7262 and see what they propose. I think there is a design flaw with this model and they may be taking care of the problem. I would expect that a repair to the ballast would be a shop repair. Please post what response you get from Panasonic.

call them alot pp say they give u free one cuse they knw better ok

SOURCE: My Panny AE700U shut down & won't restart

HI there

This is a faulty Mainboard that will need either repair or replacement.

If a Projector starts playing on and off tricks I have found it to be 99% of the time a faulty Mainboard.

SOURCE: Power button blinks green about 1 minute then goes red

There is an additional problem,

if the bulb had been replaced by a technician, call them back and ask for additional support, since they did not fix the problem.

Panasonic PTL500 LCD HIDEF projector - Unit occasionally powered up briefly, lamp lit, then shut down, standby LED flashed orange/red. Sometimes lamp lit and sometimes not. Technician diagnosed bad ballast...


The bulb is a discharge type - it needs a very high tension to work. The role of the ballast board is to convert the low voltage DC current coming from the power source in a high tension DC current for the bulb. Unfortunately you were truly unlucky : when the ballast board died it sent a high tension surge thru the power source and from there at the other components on the mainboard - the processor couldn't handle it and got fried. So now when you try to start the projector this is what happens: the power source starts normally - the status light goes to green as it should; it functions normally so it powers the ballast board and the rest of the mainboard - the ballast works so the bulb lights up; the mainboard on the other hand remains dead because the processor is dead so no sustain signal is sent to the power source; without the sustain signal the power source goes, as it should , in an very normal stand-by - the status light goes to red.
The entire mainboard will have to be replaced - you can't replace just the processor, it's glued in there. This is going to be expensive so ask a quote before doing it.

If you take the back off you might find a couple of bulged electrolytic caps on the power supply board that need change, or just buy a new power supply at www.partstore.com

I have a Graco baby monitor, it started making a noise for the last 2 days, could it be a battery problem (even with power connected)? The monitor is about 1.5 years old.


Annoying! happens to us too frequently, but this works. We ended up buying a new one and returning our broken one after owning for three months From Manual:) 5. Turn on the Nursery Unit using the On/Off switch on the side. The green power light should come on. 6. Within a few seconds, the Parent Unit will lock on to the Nursery Unit and the top four (4) green LEDs will shut off. A second later, you will hear a series of beeps and the connection LED should change from red to green. Your monitor is now ready for use. 7. If the top four (4) LEDs do not shut off, power off the Parent Unit and the Nursery Unit and repeat steps 4 and 5 above. 8. If the connection LED on the Parent Unit does not change from red to green and the unit begins to beep, press the channel "ch" button on the Nursery Unit. Within a few seconds, the Parent Unit should lock in on the Nursery Unit and the connection LED should change from red to green. You may hear an audible beep during this process. 9. If the Parent Unit is still unable to lock in on the Nursery Unit (connection LED will be red and the unit will beep), power down both the Parent Unit and the Nursery Unit. Wait for 10 seconds then hold the volume down button on the Parent Unit while pressing the On/Off switch. When the unit powers up, you will hear a single beep and all of the soundlights will illuminate. Release the volume down switch and within 2 seconds you will hear two beeps and all of the Sound Light LEDs will stay lit and the bottom LED will be red. 10. Repeat steps 5

My linksys network switch is not connecting network computer, what can i do to get it back to work?


Do you have any activity lights on the Linksys? If not your switch has no power a hardware problem. Try to power off for 5 seconds and restore power on the Linksys unit. Try to shut down (do not restart) all computers. Are all the activity lights off? If not again power off the Linksys for five seconds and restore power. Power on the computers and verify the activity lights are now green for each computer. If the computers are not networked and the activity lights are green, check your network settings on your computers, which could have incorrect TCP/IP settings or workgroup. If one activity light is not green for that Ethernet connection, check your cable connection or replace the Ethernet cable. The workgroup should all be the same name. The TCP/IP address should be the same with the exception of the last set of host digits which should be unique to each computer address.

My tv will not power up?


If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. 

Here are the symptoms...

Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.

Hope this helps,
