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

Open Question

I have Panasonic big screen television. The model # is PT-40LC12. The screen has these purple blotches. I took it apart and cleaned the light engine lense, along with the mirror inside. The blotches are still there and I would like to know what the next step should be? Btw, the bulb is also brand new. Not sure if it effects it, but just letting you know. Please someone who knows what to do, let me know?

SOURCE: PT-40LC12 fuse problem

I went here for a tech manual for the Panasonic tv.
http://www.ManualsParadise.com
then ordered
Manufacturer: Panasonic
Part Description: FUSE
Part Number: LSJA0411-1
from PartStore.com
it was mounted to the case that holds the lamp. had to remove the back panel, etc. Also think I had to splice in the fuse or something. was a while ago.

mine is broken again. this is getting old between lamps and repairs.

SOURCE: lamp meter on Panasonic PT-40LC12 ?

I just had my picture go out two weeks ago. I took it to a local tv repair shop. They replaced the thermal fuse. I also had a spare lamp so they also replaced that. I'm not sure if they reset the lamp meter but this is what I found surfing around...try at your own risk. I'm going to try this when I go home tonight.

Good Luck...

Press the power button to turn the unit on.
While pressing the Vol-(volume down) button on the projection display,
hold down the PIP button on the remote control at the same time for more
than 5 seconds. When the reset procedure is complete the following message
will appear on the screen. "Lamp time was reset to 0".

SOURCE: Cleaning mirrors and lenses on Sony big-screen projection TV

it's fairly easy to remove the screws on the back bottom portion of any rear-projector television. when the bottom part is removed, you will see both the mirror and the 3 lens. isopropyl alcohol or windex should do an efficient job. a soft lens rag can be found at any camera store. i'd spray the lens rag instead of the actual lens or mirror when doing this job.

SOURCE: Purple blotches on Mitsubishi WD 52527

yes you can clean it. i clean mine all the time. after you remove the screws at the bottom you should be able to just lift it up. it will be hard be cause there is sticky tape with a hinge that the hole screen sould just lift off. i know it doesnt feel like it but it will. just do one side at a time. now the problem with the purple spots are because you move a speaker to close to the front of the tv the was not shielded and cause it to do this. you can move the tv so that the earths magnetic field will restore it for you. make sure the tv is not plugged in when you move it for 2 to 3 days . after the 2 to 3 days plug tv back in and leave on for 2 hours. after this you can move it back and plug back in. this should fix it. if not you will need it to be degoudged. tv repair center can do this at your home. hope this help you.... thanks eddy

Panasonic DLP TV has huge yellow blotch covering most of the screen


SET uses a optical light engine--lamp which is quite hot shines into the engine---blue is first to get the light and heat and is usually first area in the lens and baffles to get damaged(loss of blue leaves red and green which equal a yellow screen.

You have a damaged light engine.

I have yellow and purple blotches on screen


I had this same problem on my Mitsubishi rear projection WD52527 model television. The optic engine was changed twice, and the blotches were still there. It turned out that it was the mirror inside the television that was causing the purple blotches. It was filthy and once the repairman took it out and cleaned it the discolorations were gone. Hope this helps

The Power Light is Red


yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

Purple blotches


Ok, so I'm about to flip a lid with my TV. I am showing purple quater sized blotches all over my screen. I bought it for a discounted price because of this issue, in hopes i could fix it. I took the back panel off the TV. ( about a 6in * 6 in plate) removed the light bulb and cleaned the bulb and lens, where the light bulb faced. I used a dust cleaner and special cloth. NOTHING! I took the entire front screen off cleaned it and then cleaned the mirror and second lens.... NOTHING! Then i heard that dusk sometimes gathers behind the lens and that should be cleaned. Try this, Its 4 screws, just be careful and remember the way you took it out, because it has to be replaced the same way.
