PT-AE3000 blotches on colors and white

Hello,

I basically have the same problem as the one mentioned in the first post of this page.

Please have a look :




I have very visible blotches, especially on (in decreasing order of importance) :
- green
- white
- red

And no visible blotches on blue and black.

What do you think I should do ? I am unsure if the projector has been used for long continuous sessions but I have reasons to believe it could have been. It was in an "ex-friend"'s hands for two years.

- do I have the slightest chances of removing the blotches by cleaning the lcd panels ? Do you do so by conducting the operation described here, or does the latter only help in the case on blobs on blacks (instead of blotches on white, which I have) ?

- can a panny service center be of any help ?

- if the lcd panels are dead, can I buy some new and replace them myself ?

The projector has around 5,000 hours of use. I have no idea if the blotches appeared suddenly or not (I just got the pj back).

Thank you
Fred

Thank you. I am trying to get in touch with Panasonic, pretend I am journalist (which is partly true) and say this is a scandal. Hope they will offer something. Here in Europe the projector has a three year warranty, and it is barely four years old.

Hello,

Thanks for this advice.

Before going further into disassembly, though, I would like to know if it can really be moisture provided that the blotches are not visible on blue. Hence I would believe it has to do only with green and red.

Removing moisture seems far more complicated than just removing dust. I am afraid it will take me a long time and I am afraid of not realigning everything properly.

Some people suggest using alcohol, others suggest water. Is not distilled water the way to go ?

Thank you.

Hello,

After disassembling the optical block and wiping the lcd panels and the rest that I could access with a dry cloth, my blotches are gone ! It was only dust... thick dust I must precise : just canned air would not have been sufficient to clean it.

So please be careful with your advices next time because I almost threw my projector away.
