PT-AX100 problem? - Page 27

post #781 of 813
I have projector and the bulb doesn't want to seem to ignite (bulb is verified to work properly). When I turn the projector on, the green light flashes and then after 30 secs the red 'Lamp' light will start flashing slowly, after a few minutes is shut off. The Iris works just fine and moves freely.

Any idea/thoughts as to what could be wrong with it? Any help is appreciated. Thanks

I had a similar problem on another projector. I was told it might be the ballast, which was expensive and there was no guarantee that it would work. In that case, the old bulb blew up and I used two friends good bulbs without success. That is why I bought the PT-AX100 so I am not much help. I would love to know if you find a fix however.

I had trouble with my PT-AX100 shutting down from the filter being clogged (oops, time to clean them again) but that can't explain what you are describing.

I bought one used a few months ago and mine quit working after 2 hours though it was well maintained and recently lubricated according to the previous owner. I cleaned the filter and instead of running 3-5 minutes, it ran for about 10? and then shut down again.

Went into the secret service menu and I also have the 'Iris OK' highlighted in red. No money for fixing right now so it's been sitting in the closet for 2 months and I'm back to using my 50 lumen Optoma PT100 LED which is just a toy but has never failed me in 2 years...stinks...

Relatively easy to fix the Iris OK in red by following the instructions earlier in this thread. I used Super Lube and had much better luck with it than with WD-40. I did it once with WD-40 and not long after had to do it again but used Super Lube and have not had to do it again. The dry kind didn't work btw.

I apologize for not elaborating....I've followed the how to's and the specific Youtube video on lubing the lower iris part (mind's gone blank now) but no change. And specifically, I checked the response of the part first, and it popped back into place immediately even before lubing so I'm not sure that's the problem.

I mean, if the part had been slow to return to position before lubing OR if the projector had stayed on for more than a few minutes after lubing (multiple times), I might have more hope but at this point, I wonder if I simply need to have the entire IRIS replaced.

Granted I used WD-40 and a q tip liberally, but still, the projector has never stayed on for more than around 5 minutes before going into cool down (orange LED) then shut down (red led) mode.

Should I still try lubing the pj again?
post #786 of 813
When I used WD-40 it worked for several months so the choice of lubs is not your problem.

As I recall, there were other solutions posted where the irus was forced into the open position (not reading them so don't remember exactly) You might try one of those solutions.

Thank you for the confirmation, I just wanted to rule out lubrication. I bought it from an AVS member here who stated that everything was operational and had been lubed recently, and was working properly. So who knows, maybe during shipping something was affected.

I may try the iris stop method but after that, I'll just have to save up (severe work dry spell) and let Heartland install an updated iris from the ax200. It's too bad, the pj worked flawlessly for 2 hours lol, no flicker or anything.

EDIT: Btw, I tried KoolKiwi's fix with the spade terminal and a piece of wire to keep the lower cam at 90 degrees, instead of the cam leaning toward the left (not straight up and horizontal).

I definitely noticed less and softer clicking but after 5 minutes, back to Standby mode.

My only other cheap option is to open the top of the pj case and check/lube the upper cam so I guess that's next.

I doubt there are many original owners left on this thread. I am one. 5 years and 3 month in before what appears to be "The Iris Issue" cropped up a couple weeks ago. Haven't messed with it until today after discovering that a 32" TV viewed from 4' away can make an almost satisfactory substitute. Today I was able to keep it on long enough to discover that the iris OK is red and that the projector now has 21758 hours on it. Then the damn thing stayed on! Went back into the service menu and now iris OK is white. So now I'll run it a few more times from the coffee table to see if the issue reappears. If it doesn't then it's back to the ceiling mount. Otherwise it'll be time to review the available options.

The first time i switched to and used 3 in 1 oil, the projector would stay on after the second reboot. After 2 weeks I used the 3 in 1 oil again and now it always starts on the first go. I've realized that WD40 will not withstand the high temps for long and turn greasy very quick that's why it's not a good oil to use. This 3 in 1 oil is the best of the best I've used so far. It took 2 lubrications to get rid of the WD40 residue but now everything is good! I'm a very happy camper right now. 3 weeks and counting since that second lubrication and still running fine everyday!

I was about to give up on this projector and buy a new different brand but now I'm sticking with it as I have always been impressed with it's picture quality but seriously let down by the iris sticking problem which is now resolved. :-))
post #790 of 813
I may try the 3 in 1 oil myself as other lubricants have not worked on mine.....previous owner swore it's worked fine with a recent lubrication. I also tried the iris stop to keep the cam perfectly vertical/horizontal but no change...

Just a quick update. It got worse before it got better. Panny would shut off regularly after under 4 minutes. Taking the advice of GMWPS3 I soaked a q-tip with 3-in-one and coated every visible moving part (only those accessible from the lamp chamber) with it. All now seems to be well.

post #792 of 813
Well I decided to try your suggestion, I've just been way too busy until today. I went to Autozone and bought a bottle of the 3 in 1 oil (clear looking). I've applied the oil using a q tip to the bottom cam shaft spring on each side of the cam from the bottom (lamp) side. I've done this 3 times so far, including switching off the unit and unplugging it for 5 minutes after each application of oil but so far nothing's changed.

In the Service Menu, Iris 'OK' is still in Red. I also noted the top of the menu said MM: 1.15, F: 1.00, IM: 2.00

So is my firmware version 1.00?

Other than the clicking iris/shutdown issue, the picture seems perfectly fine.

I've been trying to avoid shipping and paying a large repair bill but I'm going to try to get a better ballpark figure for only the iris replacement from Heartland this time. Last time the receptionist just said it could be $300 or 600, not sure.

If I could get it fixed for $300 or under, I'll do it but otherwise, it's part out on ebay or CL time.

I'll try lubing it a few more times over the weekend and see what happens...
post #793 of 813
Well I tried the 3 in 1 lube, in fact numerous times despite the fact that the cam rotated freely already and no success. I also took the center copper lead from some coax cable and used it to hold the cam perfectly perpendicular (hor/vert). I will say that the click-clack noise completely disappeared with this but the pj still shut off after 2-5 minutes. After playing with the cam position via the coax wire too many times to recount, I've finally given up out of frustration and will be sending it to Heartland as a last resort.

Everything else about the pj worked fine so we'll see what happens.

Boooooo!!
post #794 of 813
What's odd with mine is that the "click clack" noise seems to always be there at startup. Then it goes away after a couple minutes, and everything is fine.
post #795 of 813
I've been experiencing the auto-iris problem for several years now and each time it started acting up, I would apply WD-40 per previous instructions in this thread. Even with additional applications of WD-40, the projector got to the point where multiple power on cycles were required to get it to stay on. Eventually, that stopped working about a month ago as the projector would not stay on for more than a few minutes at a time. As I looked inside the projector around the auto-iris pivot points, I noticed fine dust buildup along the airflow channel. The dust seemed to be made harder by the fact that it was was heated significantly by the bulb when the projector was in operation. It occurred to me that the dust could be building up on the pivot points, so I sprayed some automotive mass air flow sensor cleaner (safe for plastics) over each pivot point making sure to not get the cleaner on any other parts. Since the cleaner evaporates by itself fairly quickly, there was no need to clean anything up after application. After cleanup, I powered up the projector and it stayed on! For now I'm going to leave the lube out since I think it was the cause of the eventual failure. I've been up and running flawlessly for a month now.

Just one word of caution: The cleaner is flammable, so make sure you let it fully evaporate and allow the projector to air out prior to power up.

Interesting solution. I think people in the projector forums find that WD-40 is not as effective for auto-iris pivot points as a fine oil machine like 3-IN-ONE® Oil.

I'm double posting this. The temp light comes on regularly even though I vacuum the filter regularly. It's on right now. Usually it leads to a shut down that requires a turn off, restart. Any ideas as to what might be causing this? Thanks.
post #798 of 813
I was given a PTAX100E as a gift from a friend. it had the iris problem when he gave it to me, that was the reason he bought a new one. I tried TF2 on the cam, it's a Teflon light oil. Worked fine for 3 months. Now nothing will work. I've just completely dismantled the projector, taken the iris unit out and sprayed it with contact cleaner (IPA). Fingers crossed that: a, I can put it back together and b, it works!
post #799 of 813
If I remember correctly, somewhere in this thread is a fix using some copper wire or a paper clip.
post #800 of 813
Update

All good. Self check shows Ok for iris. None of that clicking on start up and stays on first time. Not that hard to rebuild either. Very happy bunny right now!

An update. My local repair shop tells me it's a bad power supply. $72 parts, and $150 labor. I'm going to go ahead with it, but when the lamp dims beyond redemption I will not replace it. Enough is enough. Lamps are a major rip off, much like razor blades and printer cartridges. In a year or so a decent 75" may be affordable, and I will abandon projectors forever.
post #802 of 813
Well I finally bit the bullet after the 3 in 1 oil, metal clip and other methods for humoring the finicky Iris but nothing worked for long so off to Heartland with it!

Even insured for a few hundred, it was only $20 from Memphis in the original Panasonic box/packing with extra packing material from me.

Got a call from them a few days later saying to put it pack into new like condition would be $1900...convergence off a hair, a tiny spot on the lamp, Iris and Iris cable (finally something I care about lol). I ask, how much for just the Iris/cable? $280 for parts/labor and shipping back. I paid $300 IIRC and it's been sitting over a year now so I say what the heck, "Charge It!" tongue.gif

We don't even use the backup pj (toy Optoma PT100 at 68-70") once a week so hopefully the Panny will hold up for another year or two but if it breaks, it's going in the trash.

I'll miss the great flexibility of that unit though...

Hello Everyone,

 

    I have a question on how this projector is supposed to behave when trying to start up. My projector had a bad fan which sounded like a jet engine so I decided to get a replacement. I opened up the machine, replaced the fan and everything was good to go. That is until I put the outer case back on. Now it starts up, I see an image for about 20 seconds or so, there is some other noise that sounds like a servo motor to some degree moving then it powers off. There is no fan or other noises at this point and I don't see the Iris trying to move at all through the lamp door (I put a screw driver in the switch so it can power on with the door removed). Removing the case doesn't help anymore either. I've replaced the lamp since this problem started up. I haven't disassembled the projector again to see if I've knocked something lose. 

 

When should the fan start up, Immediately? Mine doesn't power on at all during this short powered on period. I've tested the fan being powered separately and it's fine. Is there something else I've knocked loose? Which of the cables is the one controlling the iris? Or does it sound like I have the plane old stuck iris problem needing lubing/force stopped/replaced etc?

 

Any help is appreciated,

 

   Dave

Which fan did you replace? There are 4 in the AX100U. Was it an OEM fan part?
post #805 of 813

I replaced the Toto Blower fan: TYF140FJ11. It worked fine right after the replacement, but before I put the case back on. 

 

As another update, I did the 3 in one oil to the bottom Iris and it for sure moves better and doesn't get stuck or move slowly at all now, but the turning off after 20 seconds or so remains.

Sorry, I'm drawing a blank on that part number you posted. Here are the fan parts numbers from the service manual for the PT-AX100.



Most or all of these fan part numbers are shared with the PT-AX200 however all of these OEM are listed as unavailable at this time by Panasonic or any online vendors.

I can't find any reference to TYF140FJ11, I'm assuming you pulled this number off of the old fan. Yes?
post #807 of 813

Correct, I got the same fan as what was removed from the PJ on my initial dissection.

If it seems like the fan is operating normally then I have no clue, sorry. The reason I was asking about the fan specifics is because occasionally someone tries to use a fan that looks similar but isn't. A projector fan needs to communicate with the mainboard to maintain a status condition, if it doesn't the projector refuses to operate correctly. Perhaps someone else has a better idea of what's going on here.

No problem, thanks for checking.

 

Though does anyone know the timing of the start up on this projector? When looking at the iris during the first 20 seconds or so, should it move? Should the fan start right up immediately, or does it start up after the PJ has had some time to heat up?

post #810 of 813

I was able to open the projector again this weekend and I found this spring floating around loose. Could this have to do with the problem I'm having of the PJ powering itself off after just a few seconds? If so, does anyone know where this belongs for me to replace it?
