Is everyone else still OK with their film? I've only had mine done for about 3-4 months.
for Jason; look at my previous posts; i have detailed photos about disassembling the light engine step-by-step. the ballast doesn't need to be disassembled and the light box does not need to be removed from the TV just the middle component the light engine.
Looking at the old part, it seemed to burn in the center with a space anound the damaged section that is still clear.
Any ideas how to stop this from happening?
Here's a photo of what my old one looked like:
for a piece of glass, taking apart a uv-protecting lens filter for a camera ought to do the trick. (use a dremel to cut the ring off then traditional glass cutter to cut down into a rectangle.
I will wait 'til it gets much worse before i monkey with it; maybe it'll make a year. I didn't glue on the filter so it should be a very easy swap this time, i wonder where i put that spare filter
But why only the blue? Mine only lasted a three months.
"the dirty deed is done. And I mean dirty.... I spent plenty of time cleaning dust out as I'm sure you did as well.
In my professional opinion, the location of the air filter that feeds the fan that cools the LCD panels and polarizers (that was a mouthful) is poorly placed and difficult to clean without full disassembly. The root of our woes, blue has the highest energy waves, and is most critical to keep cool.
Sony had a real big batch of this same problem on their LCD projection sets....reeaallll bad. I changed out SO MANY Sony light engines and EVERY ONE had the same yellow blotchy picture......
They had a recall put out on them where we removed the light engine, and put some new ductwork that put the air filter (for the LCD panels and polarizers) in a very accessible place, all you had to do was remove the back and vacuum that filter (after the recall)
I don't know about your air filter (on the bottom of the light engine directly under the lense) but mine was fully clogged, when I attempted to vacuum the filter it was so old and rotten that it ripped badly (frowny face).
SOOOOoooo, I took some foam padding and cut it to size (kind of sloppily) and squeezed it under there after everything was in its place.
If you want a picture I can get one easily. I would suggest that to avoid this problem in future, all owners of this set replace that filter with one they can easily pull out and vacuum.
Thanks again for the cheap fix! It is much appreciated, I have been dealing with this for MONTHS!
I did crack the glass while using a razor to scrape it.... oh well, I just took it out and put in the filter as suggested.
So in a nutshell, I believe it is a clogged air filter that causes the hottest polarizer to burn out, the flow of air is from the bottom up, and the top of the polarizer is always burning first, probably because there is justI enough airflow to cool the bottom of the polarizer (the polarizer is upside down in reference to the picture).
What kind of material could you use to make the replacement filter? Could I cut a piece out of some other filter, like a furnace filter or one from a vacuum cleaner?
Jim was kind enough to send me another hunk of polarizer, so I went to do the repair again.
The polarizer from the previous repair was burnt as expected, but this time it was a different shape to the burn mark, and the film had warped.
When I removed the bad film, there was condensation under it, and it was the exact shape of the burn.
Not sure what to make of that. for now I’m back up and running though, looks as good as new (again)!
I read all the posts and contacted Anchor Optics to inquire about their Vermillion color polarizer film (stock# AX27803).
Unfortunately, this item is no longer available. I have been searching to find other vendors without any luck.
Does anyone know where I can buy this film?
I hesitated to post any photos of the air filter modification on the chance it didn't work, well it didn't. It clogged up fast.
I will see if I can get another filter from Superlemur as well. I am seriously wondering if it is an airflow issue....
I have a Panasonic PT-60LC14 with the yellow glob starting in the center. I am mechanical but would you share whatever info, instructions procedures and where to buy what with me. I am retired and would like to fix this TV if possible.
Thanks for any help
Now it turns itself off after a few minutes with a voltage error. If you want a project here you go .. till, let's say the 19th of June. First come first served.
