    I took my Panny PT-AE100 back to Audiovision today to have it returned to Panasonic for service.

    I noticed a while ago that white scenes revealed a burnt yellowish colour in the centre of the screen and a light purple around the edges. I was hoping it was the lamp but after 1038 hours it's not even a quarter into its life.

    Lord of the Rings just istn't the same on my old 28" Sony widescreen. It looks tiny now after using the Panny for 6 months on a 80" screen.

    Hurry up Panasonic!!!

    Over 1000 hours!

    Who said the AE-100 wasn't reliable :D :D

    Let us know how it comes back.

    BTW, 210 hrs on my unit now, 280+ on the previous one & no problems with either (meaning no red LED of death).

    I first noticed the problem during the world cup but wanted to make sure I got it checked out whilst still under warranty.

    I find a 1000 hour prob worrying, as most people seem to have their problems quickly. I must check the hours on my PJ, I haven't a clue. We just turn it on and there it is.

    It didn't suddenly appear, I noticed during the world cup.

    The problem is so minor that it could have been doing it for ages without me noticing.

    It wasn't a major problem, the image was a little yellower than it should be, that's all. It was only obvious on a white screen.

    I have 460+ hours on mine now.
    I wonder if your lamp is fading prematurly?
    Has anyone ever noticed there fan pitch change? My PJ's fan can sometimes speed up then slow down while watching a film. It only doe's this on the odd occasion.

    I noticed this yellowing of the picture on my previous ae100 but i thought it may have been caused by smoking in the same room as the projector, although i was still being careful to puff into the air purifier(stupid habit) it was a large round area that did not seem to effect the very outside edges of the picture. hence smoking in the front room is now a no no. i would be intrested to know the cause in your case jonny. I am at around the 250 hours and this one is still going, touch wood. flicker is still there on the lamp. I got to around the hundred hours mark and I had a windows desktop on the screen at the time and i noticed a couple of fairly bad flickers followed by what i would estimate to be about a 5 to 10% drop in light output and it seems to have stayed at that level. It does not seem to have dropped anymore. the lamp is more or less flicker free in high but i am running in low as i want the high lamp life. I am just hoping that the occassional flickering is not detrimental to the so called 5000 hours figure quoted. time will tell.

    All the best....Splice;)

    A round yellow blob which starts off very small and gradually increases in size?. If it increases to quite a large round yellow blob in the centre of your screen then its usually caused by the projector overheating.

    Make sure there is plenty ventilation below/above the projector.

    It might be fine dust collecting on the panel and then getting scorched by the lamp. ( Might even be on the lamp itself)

    All this heat and so little cooling (because the punters want a quiet pj) is quite a challenge to the mechanics of the unit. Without using (expensive) space age materials I think it is inevitable that things will warp under the extreme temperature. The question is, how much this will effect the picture over time.

    The eye is very sensitive to impurity of a solid color (esp. white). How many monitors/TVs can produce a consistent pure white across the whole screen? - none that I have seen.

    Splice:

    The (slight) flicker that you see on the AE100 in low lamp mode is normal AFAIK. Perhaps this is down to sensitivity of the mains supply (which can fluctuate).
    Occasionally I get a couple of major flickers in short succession, usually a few minutes after switching on the pj.

    A Panasonic engineer has assured me that this will have no detrimental effect on bulb life. I hope he's right!

    Yes, I clean it quire regular, about every 2-3 weeks seems to be enough.
    I take it that nobody else has noticed their fan change pitch :(

    Mine does Tim, as did the previous one I had.

    AFAIK, this is quite normal & proves the temp monitoring (primitive as it is!) & speed control is working.

    It depends on ambient temp. A warm room causes mine to "speed up" more than when it's relatively cool.

    Timh,

    Sorry, I meant to answer you; in the recent heatwave I noticed the fan switching into high gear once or twice (the same as when you switch into standby.) The first time, I wondered what the devil it was; the fan normally is all but inaudible.

    By no means! I'm on the south-east Kent coast. And some days recently have been ridiculously hot.

    I've just got off the phone with Audiovision in Brighouse.

    I took my AE100 in 5 weeks ago for repair for a yellow blotch and purple edges..

    Apparently the Panasonic service centre in Leeds is waiting for a new prism to arrive. They expect to have it in early October!!!!!!

    It looks like someones theory of prism warping may be true.

    :mad: At least 2 more weeks of watching a 28" widescreen telly.

    I asked about the warranty on the AE100.

    Apparently, it's only 1 year RTB (not 2) but I'll get 12 months from the date I get it back.

    Hi

    Jonny1973 - amazing. I have the exact same problem. Yellow in the middle, blue/purple on the right. Now since i bought mine from PriceJapan.com i would have to send it back to Japan and besides from taking a long time it´ll also cost about $200. Does it look like they will repair this free of charge? I don´t really wanna send it to Japan and have them come back to me and say ´Machine got too hot, not covered under warranty.´ ;)

    Timh: Yes, the change in pitch happens regularly on mine.

    Cheers
    Patrick

    Of course the repair is free. It's a fault.
