Question about Panasonic PT-40LC12 40" Rear Projection HDTV

1 Answer

New Lamp or not New Lamp

Ok, I it looks as if my lamp burnt out for a second time. I ordered a new lamp and installed it. It didn't work, just a constant flashing Green Light. I measure the lamp leads (lamp side not TV) and see zero resistance. I called the lamp provider, they say it sounds like a bad lamp. I ship it back, get a new lamp same problem (note: this box was damaged upon arrival). So my quetions: 1. Would the lamp measure any resistance? If not how do I test the lamp? Or is there a more sinister problem afoot?

    I heard a pop up from my TV that caused a blank on my screen. Then, I quickly turn-off my TV and waited for a couple minutes to turn it on again. The green LED light showed up but the screen was still blank.



    What should I do now to make my TV run again? Is any lamp popped up or the thermal fuse exploded? How do I get it fixed?



    Thanks

    Whenever the TV is first turned on it indicates on the screen to replace the lamp. The picture appears to be fine, but we just got the TV from a family member. Not sure if the lamp really needs replaced or not? Certainly do not mind spending the $$ just want to make sure it is necessary and not just a programming issue. Thanks

Do a continuity check on the thermal fuse coming off of connector P1701-P1707, I believe. If it's open, replace it. It's housed right above the lamp on the light engine.

If you put in an osram "neolux" type lamp--these will NOT often work in Mits. tv sets. And MIts often sends out Neolux bulbs now. A phillpis bulb for this works MUCH better.

Check for lamp if it's properly installed. You must have screen on yor tv in order to reset lamp time(make sense ?) or your lamp is ok but ballast is burnt?

You cooould have a bad ballast, but it's probably either that you put the lamp in wrong, or you have a defective lamp though. There's a 33% chance that any of those are the case. Unplug the TV for 30 seconds. Plug it back in. Try turning it on again. Make sure you didn't over tighten the lamp during install. Especially the screw on the side. It should be a tight connection. Send the lamp back and get a new one. Usually they come with a warranty. If the new one doesn't work, it's either the ballast, or the power supply.

AsI have a sony kds55a2020 tv, I recently replaced the lamp because the lamp light was on. after I replaced the lamp, the tv power blinks 4 times and never comes on. what else can it be?


hi,
Check is the lamp is properly installed or not. If the tv was at working condition before replacing the lamp then then the new lamp is not properly installed. Check one more time. If you can then just remove the new lamp and insert it again. Make sure that the lamp is properly attached. And then check.
ok

I have a Sony KDF-60XS955 tv. It won't power on,


I have that manual. There are three lights to the left of the power button. One is labled LAMP. The manual states "The projection lamp, which illuminates the picture, has a limited life. If the screen becomes dark, the color looks unusual, or the LAMP indicator on the front of the LCD projector TV flashes, it is time to replace the lamp with a new one (not supplied). Use a Sony XL-2200 replacement lamp (not supplied) for replacement. Use of any other lamp may damage the LCD projection TV." I also found in a different page " LAMP LED lights up in red when the lamp for the light source has burnt out." I guess burnt out would be extream. I found one other if you had opened the light bulb cover and didn't close it properly. " If the lamp cover is not reattached securely, the self-diagnostic function may be triggered and the POWER/STANDBY indicator flashes three times." You can down the sony manual at http://www.docs.sony.com/release/KDF60XS955.pdf

Blinking red light that says bulb


It means your lamp is burnt out and you have to replace the lamp with a new lamp. When you install the new lamp dont touch the glass lens part at the front of lamp or the oil from your finger will burn the new lamp and it wont work.

TV went off, and three lights come on (green "power", red "temp", and red "lamp")for just a second, in succession from left to right.


My television had two red lights flashing, one for Temp and the other for the lamp. I removed mythe lamp assembly and the bulb filament was burnt out. I order a new lamp and housing unit UX21517 and replaced it and now I have the red light flashing which is calling out the lamp again.

New lamp turns on flashes 7 times


Just a thought...you *might* have a bad ballast in addition to that defective power supply.That flashing could be the ballast trying to ignite the lamp. A lamp is just like an enclosed welder's arc. The ballast generates a high-voltage spark to initially start the lamp, then low voltage with high current keeps it burning. If you look into the lens and see "lightning" flashes but no lamp ignition, that's what's happening. The ballast could've been damaged by the defective supply. Also, try a known-good lamp...just to rule out a defective new one--in the shop, we kept all old working lamps as testers.
