AE700 Power on then off then on problem - Page 2

post #31 of 101
Hi everybody, This is a very technical and fearsome POST ahahah

I email some suppliers and receive quotes for Ballast and Power supply module only. I emailed Heartland without success... no answer. But I received a gift, complete service manual for 700U/700E. I do not want to put MrFent in the ****, (in case of Heartland audit this forum) MrFent is not the source.

The power supply diagram block is in fact 4 modules.
K-P.C. Board is the module with the fuses and switch on the back of the proj.
P-Module is a switching power supply (cost around 100$USD)
B-Module is the ballast (cost around 225$USD)
Q-Module is the controller mounted on the B module (someones call it microcontroller)

When logain2000 say "cost me about 400 to get fixed.", it is probably the B-Module who have been replaced. After looking to the schematic it make sens deffective B-Module cause the on off on off.

Confusing ==Is B-module can be called Ballast by some and Power supply by others??!!

MrFent , if you want continue helping us, I have another question. Just to don't get the wrong term before ordering part, is the power supply you are talking about is the P or B module?

Thanks a butch

Fent sound like you may have fixed my 700.

I may have, there's only a small number of people who work on projectors.

I'm not sure why you go no response from Heartland whatsoever, but if they HAD responded, they would have told you that they don't give out information like that on parts. Since Heartland is a service center, they do the service. I think the only actual parts that they sell as a whole are the lamps.
post #35 of 101
can someone post the exact amount that they charge for replacing power supply? I'm not in a rush to replace mine as it turns on after cycling like 5 times. has anyone done it themselves?
post #36 of 101
Hi sethotterstad,

I did not for the instance but I probably will do in a near day.

My projector is always at the service center. I called them this morning, they answered me replacing the ballast have not fixed the broblem yet... and now it couldn't be worst, the projector refuse to start. They have to call me back again to inform me what next and I will take a decision... trust this forum and fix myself or not. Anayway, I sent my proj more than 1 month ago to a service center hoping they should be able to fix but they don't. Adding to it, I find regrettable the lack of communication Pana have with other service center who have experimented this problem. Together we will find the answer... HUMM. Read my prec. posts for story and parts, I have real quotes this is not a joke but no way to refund if it do not work. I will let you know the results if I fix myself but it could be long because I didn't picked back my projector and following and depending on my decision it could take 2 to 4 weeks for parts delivery.

PS Trust in me and don't call Panasonic to have parts or speek with a tech, the only thing they say is "send it to a sec.center."

Sorry MrFent, I appreciate your help but sadly, my opinion going low, cheap, poor towards Pana. due to a lot of collaterals or chain effects.

MrFent,

What about thermal sensor TH101. TH is abv for Polyswitch man. by Raychem it is a ressettable device. It is situated just where the power supply is feed. My theory is: The internal temp in the projector is relatively low when you power it up for the first time. The proj can work perfectly for a couple of hours. Following, now put the proj in standby mode, I mean just shutting down the lamp without closing power switch on back, the internal temperature is maintained relatively high because the power supply stay powered and emit heat. Then now, powering up the projector makes the internal temperature increase faster (depending also the temp in the room). If it is defect, the power could be shut off before the limit temp is obtain because this temp sensor is pre-heated.

The new power supply is revB. Original model is ETXMM519MBG sub by ETXMM519MBGB.
Maybe the revB is not heating and cannot trig a deffective or bortherline thermal sensor.

If it is, it mean only the sensor is in cause. A max cost of 10$.

I've never seen a temp sensor go bad.
post #39 of 101
I just submit that because when I simulate troubles to my access control students, I place a bad polyswitch. TH101. And it cause the same problem. I have to specify TH101 is mounted on module P, and there is no schematic for this module in the service manual.

I just skimmed through this thread because my Dad has a 700U and it just started turning on and off during the game tonight. His is no longer under warranty and he doesn't want to spend a fortune or the time having it serviced.

So, how or where can he get his hands on a service manual and power supply? Or if anyone has serviced the projector themselves would you mind posting a walkthrough. Thanks in advance.
post #42 of 101
Some threads are saying that this might be the bulb. I am confused.

Pointous: What is the status on yours now. Is it fixed?

Also, which service dealer did you deal with. I am based in Montreal.

Thanks
post #43 of 101
My bulb went out at 720 hours. At 750 hours, the power started shutting off. Now I can't even get it to power on anymore. Fortunately I have it under my Visa card warranty (which I just extended to 5 years). I'll be calling Panasonic for service information...and will be sure NOT to recommend Panasonic projectors to anyone again.
post #44 of 101
Hi everyone, this is my first post. My AE700E died with the same power on / power off problem. This thread is great however I cannot figure out exactly if it says that the failed module is the power supply or balast ?? Also can anybody from Australia tell me where should I order this part from ?
post #45 of 101
Does anybody know where to order projector parts such as this AE700 power module in Australia?
post #46 of 101
HI, Merry Xmast time to all of you.

I was not posting for a long time but i just want to give some news on the PT700 power supply fixed august 06.

It is working fine. Lamp is now over 1200h.
post #47 of 101
Just wanted to give a big shout out to all of you guys. My AE700E started going on and off, then just wouldn't start again. Seemed like it had to do with the heat, as if it was rested for a whole nite, it would typically turn on, but then off again after a few minutes. The device is about 2 years old and therefore out of warranty. After some research I hit this thread and it sounded like the same symptoms. The problem had to be P-module indeed. After some quick calculations as to how much it would cost to bring the projo to a shop here in Switzerland, I decided to give it a go and replace the module myself, convinced that it was the issue. I bought the service manual for the AE700 online for 7$, and took it apart, to see if the repair was doable (I am no techie). I managed to get all the way down to the P-module, cleaning all the parts from the dust that had accumulated, took a look at the module, nothing seemed off, then put the projo back together. Same issue, on and off. I knew then that the repair was doable. It is relatively easy actually if you have the service manual and the proper tools. I ordered the part for 130 off the internet, had it forwarded to Switzerland by a friend (parts as deliverable only in the States). Took the projo apart again, replaced the P-module, put it back together, tadaaaaaa. Works like a charm again. So, if your AE700 goes on and off, it is most likely the P-module. Repair yourself for less than 150$, you need:

-No particular technical skills
-Some guts and a bit of patience (taking apart and back together takes about 1h30)
-A replacement P-module
-A service manual
-A screwdriver (X), preferably magnetized, as some of the screws are dificult to remove without losing them in the machine

Given that the part number for the P-module has changed from the original, I say panasonic knows about the problem, but refuses to consider it a design flaw, which is ********.
post #48 of 101
Merci beaucoup for the information. If I hadn't extended the warranty on mine to 5 years, I would consider doing the repair myself. Hopefully the P-module won't need to be swapped out a second time!
post #49 of 101
Mine just broke also, and I'm pretty sure its the same problem so many have reported (bad power module). Based on searching all the forums, I think its best that I replace it myself.

Only problem is that I can't find a copy of the service manual. Can someone post a working link if there is one? Or PM me? I found a broken link to it, and that's all.

I ordered the part directly from Panasonic:
ETXMM519MBGB
http://www.pasc.panasonic.com/epartr/PartsList.asp

I saw other sites that sell it, but it was the same price so I figured I would buy directly from Panasonic.
post #50 of 101
I just replaced my p module, it turns out to be a pretty easy job. The projector was back up and running great yesterday. I was so happy. Then just one day later, the thing is broken again (same thing it was doing before, power on -> then off -> lamp LED blinks red, no illumination). I know it must be the p-module, because it did the same thing before, I bought a new one, installed it, and it worked fine for a day. Has anyone else ever seen this repair fail again like this? Do you think there is something else defective that is somehow killing the p-module?

I have never abused this projector at all, and only used it for a few hours yesterday with no problems, then it would not start up tonight. I am really upset because its out of warrantee and I just spent hundreds of dollars for a new bulb and a new p-module. I guess I'll try to see if panasonic will replace the p-module they just sent me free of charge but who knows if they will go for that and even then why should I expect a different result? I REALLY don't want to spend hundreds more on this thing by sending it to a repair center that is probably only going to do the same thing I just did.

I really think panasonic should acknowledge this defect (afterall they have a new part number for this p-module, so something changed on it). After this negative experience I doubt I will ever buy another one of their products not to mention the bad publicity they will get from me.

UPDATE: Panasonic is replacing the p-module they sent me last week. I will give this one more try. Still not sure what I'll do if it doesn't work - I'd hate to scrap this thing and I'd hate to pay some repair center on top of what I've already put into this for a projector that is now 3 models out of date. It was a fantastic projector when it worked...

Hi TraderGordo
I hope the new P-module will solve your prblm but did You tell "lamp LED blinks red". If it is... this is not exactly the same problem described in this thread. Problem description is --Do your PT 700 going off and back on by itself (without touching anything)--
If the lamp LED blinks could be different. Without spending more money, check if all fan running properly because each cooling stage have sensors who caused proj to shutdown. Be shure to clean the filter and remove dust on the fan. Finally, it could be the Ballast but I never heard it happened. If you need more help send me priv. message again.

Well I read all the posts from various threads and various different websites, and it seemed like SOME people had the blinking lamp LED and others didn't, but the p-module replacement seemed to fix the issue for both. I'll clean the fans and whatnot this time. But the blinking lamp LED according to the manual means that something is wrong with the circuit? I don't know, I'll give everything a good cleaning. Still not sure why it would have worked fine for one day with the replacement p-module if that wasn't the issue...
post #53 of 101
Update - got a replacement p-module from Panasonic today, installed the new board. I still couldn't see (or smell) anything wrong with the one I was replacing. But this time I put the new bulb in at the same time (even though the old bulb has not actually died). My theory (guess) is that maybe the old bulb is somehow destroying the p-module (no idea how that could happen though). At any rate, just like last time, projector is working great again right now, I'm using it as I type, picture is great, everything normal. But it worked fine for a day last time. I'm almost afraid to turn it off...

I did look around inside the projector, tested the fans, but there were no problems and they weren't dirty, actually the entire inside of the projector seemed remarkably clean. Air filter was replaced with a new one the last time I swapped out the p-module.

p.s. Panasonic told me they would send the repacement to me via 2 day delivery along with postage to return the bad part. But they actually only sent the return label without sending the part, along with a perplexing letter that said if I didn't return the old part within 14 days my credit card would be charged. I called to ask them why they didn't send the part they said they would send, and why would they charge me for a part they didn't send if I didn't return the old one? Customer service guy was pretty clueless but said they wanted to test the old part before sending another one (OK - I'm fine with that, just tell me that from the beginning and not after the fact, and don't send a letter telling me you will charge me for something you haven't sent). Anyway, I returned the old part, but the pre-paid postage was apparently for super slow ground freight across the country. Eventually they got it, and then after a few days of testing (apparently) overnight FedEx'ed the new one to me. Wacky, wacky company.

UPDATE AGAIN: This time it worked for 2 days before dying. Ugh. I've pretty much had it, but I guess I'll try the repair center.
post #54 of 101
I've had the AE700 for about two years as best I recall. After a few months the picture seemed dimmer, so I decided to buy another bulb directly from Japan. I installed that and everything worked fine until yesterday when the PJ began the on-off cycling. Because it sits on a high shelf behind the back wall of my HT (in a utility space), I didn't check to see what the LED was doing.

I decided to have a look at the bulb, but wasn't able to examine the innards very closely. The lamp time showed only 84 hours on this bulb, but I decided to install the original bulb again to see what happens (I found a note I had made stating this bulb had 325 hours running time).

Thus far I have run only a short test (maybe ten minutes), but no more on-off action during that time.

I am confused about the underlying cause of the on-off cycling. Is it really a faulty lamp, or the p-module so many have had to replace? My inclination if the problem recurs is to grab one of those bargain priced Sharp XV-Z12000 IIs and take my loss on the Panasonic.
post #55 of 101
Well from the best I can gather - if you have the red "lamp" LED blinking, your problem is both the p-module AND something else (which is still a mystery to me) - I don't really know for sure. I think some people replaced both the balast and p-module to solve the problem. If you just have the power on/off problem, I THINK there's a good chance you can fix it with just the p-module replacement. The problem you had with early bulb dimming is something else entirely (probably a bad bulb?).

If you (or anyone else reading this) are ever planning to just throw out your ae700 please send it to me for spare parts! I'm kind of determined to keep mine alive against my better judgement. Maybe because it was my first projector and I used to be extremely happy with it and I'm holding on for nostalgia I've gotten very good at opening this thing up and removing any part in record time, heheh.

Interesting thread.

Because, my AE900 is having the exact same problem.

The twist is - if I pop the bulb out and put it back, it works - for a day. I've to do the same routine the next day - I've done that 3 days now. Just found out from panny, the projector is out of warranty (somehow thought it was 3 years warrnty, not 1 year). The service company they transferred to wants some $130 just to take a look at it - apart from the shipping. Considering that the projector is going for $800 on e-bay not sure, a repair is worth it.

Anyone knows of a local (Seattle) repair place ?
post #57 of 101
I believe you can find all of their repair centers via their website - but based on what I've read, you are probably better of sending it to Heartland Services (which is probably the place they recommended anyway, because its the place they recommended to me, and I just mailed mine off to them this week). Supposedly they really know what they are doing and have quick (5 day) turn around times.

Some people that went to local repair places said their projector was gone for a month or more, they didn't know how to fix it, replaced parts that didn't need replacing, charged a lot more than expected, or even returned the projector without fixing it.

If the projector is going for $800, and the repair costs anywhere from $200-$400 then its probably worth it. You could also probably sell it "as is" with problem described on eBay, and probably get a few hundred for it I suppose. Either way, a new projector is going to cost you a heck of a lot more than fixing your old one.

Well, anyway I was looking to buy a 1080p projector ... and this (1 1/2 years) is the longest I've had a projector - I usually sell off within warranty period. Even my wife was asking how come we haven't got a new projector lately ...

Anyway, I need to check whether it is better to get the projector repaired and sell it or sell it as is.

Towards that end, how much does it cost to get the projector repaired - if it is only the power supply that would be replaced ? There was some talk of possibly doing it as a DIY - in that case how difficult is the replacement and how much does the part cost ?
post #59 of 101
I think that info is in this thread, but this was for the ae700, don't know about the 900. For 700, the part costs about $100+shipping+tax and its pretty easy to swap out yourself. I don't know what the repair center will charge ($130 to look at it, and another $100 for the part? I should know soon).

Heartland Services charged me a total of $274.10 for diagnosis of the problem, replacing the bad part and shipping it back. Fortunately I had paid for my projector with my Visa card and all of this was reimbursed under their free extended warranty policy.
