Panasonic PT-AX100 - Page 152

So I cleaned my filter and it was dirty. The flicker seems a little better, but it's still there. Dang it's annoying. I'm running the bulb on Normal now to see if I can burn the flicker out.

I've just taken hold of one of these projectors but have noticed when looking into the lens there are dust particles inside. Has anyone taken it apart and cleaned the lenses without messing up the alignment etc?

If it's not affecting the picture quality it's best to leave it alone.

Does anyone know anything about this motorised filter that slides in front of the lamp? I can hear a motor running momentarily, but nothing happens. After opening up the case, i've noticed that the gears that engage with the sliding filter is missing. What does this filter do?

Only just now noticed this thread. You have the same problem as I do: http://www.avsforum.com/t/1452868/pt-ax100e-loose-parts-gears-of-some-sort-of-motorized-filter
My investigation so far has only determined, that the part it moves is the Cinema Filter. But I don't know more than that

Hey guys, I've recently purchased a used AX 100 used that worked great for the first couple of hours then died on me and I could really use some help.

The unit looks really good on the outside and had good maintenance (filter cleaning,etc and I trust the guy) but the second time we used the pj (turned switch on, then power button,etc) I noticed that inside I could hear a noticeable click, every second or so. The image lights up normally, the clicking seems to die down but then comes back again a minute or two later and the image goes from normal brightness, to dim, back to normal then goes black. I check the unit and it's now in cool down mode (solid orange light) and then goes to solid red (standby, power down).

The unit's temp lights are never lit, and there's no message about the lamp, plus this is smoke free home and again has only been used for a couple of hours so far.

I pulled the bottom cover and followed the wd 40 lubricating procedure for the iris issue but it seemed fine before application, and after the pj is doing the same thing.

I only went w/the Panny because I needed the flexibility of the 2x zoom and only wanted 720p without spending alot of money right now due to the economy.

So if anyone has any thoughts, experience etc, it would be appreciated. Off to do research!

Thanks!

Just put my fourth new bulb in last week. Original Panasonic bulb which works perfectly. Yesterday when turning it on it only ran for about four minutes before shutting down. No temp or bulb lights, just orange on the standby/off which soon changed to red. This happened every time I fired it up (4-5 times) during the course of the evening. Could only turn it back on by shutting it off completely. This has been a very reliable unit that I don't want to part with so soon. Any ideas as to what might be the problem? New bulb, new filter. ????

Mine did that when the filter was dirty but you probably thought of that. Or was that the other issue that requires the oil of the little area? One of those.

Brand new filter, and this projector has never suffered from the iris issues that seemed to have affected so many. Gettin' down inside with some lubricant has never been necessary in my case. I'm still in shock that things could go from good to bad so quickly and with no advance warning.

If it is a new filter, clean the old one and try it. I mean, if this problem started with a new bulb and a new filter it is probably one of them. Try the old ones and see if you can isolate it.

I assume you have checked the help screen and don't see the dreded red OK?

Does anyone know if it's possible to find spare parts for these things anymore? I have unit that wont start the lamp (fans ok, green power led and LCDs show picture when checked with other light source) and P-module gives 384 and 14VDC to ballast so it should be ok so quite likely the problem is in the ballast. I tried to search for the ballast part number TNPA4048 but found only one site that sells it and they're out of stock (wont even allow to order).

Is there anyone running an AX100 with over 2,500 hours on it who doesn't have polarizer issues? Mine is starting to get pretty bad. Was going to upgrade to a new unit this past fall, but there seems to be a real lack of options these days imo.

What would be the characteristic symptoms of a defective polarizer? I have over 21,000 hours on mine, and the picture is still quite satisfactory.

color blotches that are always there, even if they might only be visible against a uniform background. My previous panny started getting blue creep on the lower left corner as it aged, and it got progressively worse over time, spreading up towards the middle of the screen. My AX100 has been showing a yellow image that is mostly noticeable during dark scenes. unless i'm mistaken, this is due to these models having organic panels which degrade over time. newer LCD units use inorganic panels which do not suffer from this degradation. something like that anyway. lol

see some examples here...
