Light Engine? (The white light will roll for a couple minutes then turn red indicating i need to replace my bulb but it never gave anykind of warning. The manual mentions a orange light should appear when bulb is about done, but that never happened. I'm curious if I should replace the bulb or if it is something else. I've had the TV for about 18 months) I had this same problem, replaced the bulba dn still nothing. Then they told me to replace the light engine which acording to them is another $800.00. Are there any other possibilities?

The gentleman above gave you the correct starting point. There are red and amber lights. Amber usually indicates a problem with the engine electronics or emissions system. Red lights are related to charging or alternator problems and engine overheating. If a light comes on you need to check the related system before you wind up disabled on the side of the highway.

There is a list of things you need to check, but offhand I'd say that the 5 volt line is low and probably right on the"edge", which is why it works sometimes and not others take a look at this list:
Cause #1
1. (Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for
12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check
for an open F9A09 on the Power PCB, if it is open replace F9A09 part #
283P127060 and the Light Engine part # 939P977010 3. (Lamp may light and go out)
Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if
low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the
Power PCB (part # 930B921002) 4. At power on the lamp turns on and off three
times and then the unit shuts down with a red lamp LED (lamp error). Replace the
Light Engine part # 939P977010 5. Lamp enable line at J14 pin 6 does not switch
to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light
Engine part # 939P977010 6. Lamp enable line at connector J14 pin 6 on the
Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low)
after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB
(ballast) part # 939P978010 7. Lamp enable line at connector J14 pin 6 on the
Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-
volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light
Engine part # 939P977010

I would say try #3 first, the two caps on the pwer supply board. A couple of warnings: as always, unplug the unit before servicing. The power supply is located on the left side, if you behind the unit. It is in a shielded box and the shield has VERY SHARP EDGES so use care when you try to open it or you will slice your fingers.
Please be sure to rate this solution. Thanks!

Last Saturday evening, I experienced the exact same behavior on my Panasonic PT-52LCX65; it shut itself off without warning. I turned it back on, and it shut itself back off after about a minute, and the red "Lamp" LED on the TV began blinking.

I never got any warning message that the lamp was about to go out, but I've just replaced the lamp and now the TV is working just fine. We had to mail-order the new lamp, because neither H. H. Gregg (where I bought the TV on "Black Friday" 3 years ago), Fry's Electronics, nor Best Buy carries the part locally.

My wife found the new bulb WITH its holding apparatus for something like $120 online, roughly half what other sites were charging. We paid roughly $55 for UPS Next Day Air. The first bulb that was sent arrived broken (some UPS rep apparently thought "Fragile" meant "Shake and Drop"), but the company we ordered from cheerfully rushed us another one, and the second one was in much better shape. (Panasonic doesn't pack these replacement bulbs very well; there's a heavy bulb with a lot of air around it that Panasonic doesn't fill.)

More details available if anyone wants 'em. Hope this helps. -- ChuckE

There are two black plastic clips behind the the air filter, remove them and release the whole assembly to access the lights.

If you still get in troubles, have it replaced at a petrol station, they will help you in fitting the bulb, and it won't be expensive.

There are a lot of sites that sell bulbs for those. Use a search engine and the model with the word bulb. Be aware that it may be the ballast though.

If the red light scrolls through, you need to replace the bulb. I replaced the my own bulb, and when I tried to turn on the tv the light kept scrolling. What was wrong? I DIDNT FULLY REASSEMBLE THE TV AFTER REPLACING THE BULB.

Make sure that all the screws are put back in and it will probably work if you have replaced the bulb.

Hi,

This is due to thermistor problem. Near to the lamp one thermistor will be there please check connectivity. if it is failed please change the same.

Tried to turn it on? Sounds like you need to replace the lamp. However, I got an additional week out of my unit. Although poorly dimmed and the red Lamp light blinked constantly for that one week, at least it gave me enough warning to seek out a replacement. But so long as you're not mistaking the Power/Standby or Timer light for the Lamp light then I would have to agree with you. http://store.l-f-l.com/prod/A-1606-034-B Includes shipping to the United States and no sales tax outside of California.

its probably pretty close to time at 18 months and they often give no warning, I believe the orange light on an LG is just the lamp timer which really just counts hours. Pull the lamp out and look at it they often physically break inside and it is obvious
