War & Peace warning (I go on a lot here) Wondering if anyone may have had a similar issue? My Pioneer LX508A (50" Kuro plasma screen) is coming up to its fifth birthday this December, and I have started to have an issue which should really have started just after December and out of its five year warranty period. I am running the LX508A from my Yamaha RXV3800 receiver, feeding into the receiver I have a Dune 3 HD media player, PS3, Magic TV and a Sony Blu Ray player. All connected together via HDMI, and run using a Harmony one remote. Bearing in mind that nothing in the system is under a year old, and has all been running like a happy family together since I had all the bits (Well, some years ago I did have an issue with my receiver, but thanks to Chopsus that was fixed in settings). Over the last couple of months, when we have come to switch the system off (After a watching a movie etc.. maybe two or more hours of running), everything switches off as it should, except on the odd occasion the LX508 stays on (blue light on in bottom right corner). When this first happened, I expected that I may not have had the harmony pointed quite right to catch the IR sensor at the bottom right of the screen, so I try the help key on the harmony that runs through the switch off again and asks if that fixed the problem. To cut a long story short, what we found is that every other day, or some times more than once a day, the TV would not switch off. If I then use the Pioneer remote and try to switch it off, that also does not respond. It will not change HDMI inputs, volume control or switch to TV mode, it just locks on HDMI input 4 where my receiver feeds into (I have tried using HDMI 3 also, and reprogrammed the Harmony, same fault there too). When the TV is unresponsive to the remote commands, if I press any of the buttons on the right hands side of the TV, like standby, volume or input etc.. it works fine, but still ignores remote commands. If I keep pressing any remote command while sat in front of the screen, anytime from one to three minutes the LX508 suddenly works with the remote. All very strange to me. I called Pioneer help line and they asked me to try a couple of things (This was a series of calls over a couple of weeks, try this, then that to see if it can be fixed or the fault narrowed down). First thing was that I should switch off HDMI control on the plasma (This was actually on, but I did not need it really as the Harmony gets everything to play nice anyway), I then replaced all HDMI leads on the system, as they said it could be a single faulty lead. Instead of replacing one at a time, I did all 5 at once, the fault remains. They suggested that the PS3 is a regular culprit for stray HDMI message errors that could be locking the TV up. With the PS3 unplugged from the system it still faults. I then just used my media player plugged directly into the rear of the Plasma on input 4 (receiver not connected to the screen at all), the screen still locks up. I then just used the screen connected straight to the Magic TV via input 4 (again, with the receiver out of the game), it still locks up. At this point, Pioneer authorised the local service people in WA to look at the screen (R&I electronics of Morley WA). The service manager at Pioneer told me that he had already authorised the replacement of the HDMI main board, as he thinks that this may be a HDMI error in the unit. By replacing the HDMI main board that should cover several areas that would be too hard to track down a single fault on. The man at Pioneer also told me that they have never had this fault before and never replaced a main board on an LX508 in Australia, but they do have a new board to issue for my job held in Queensland office. When I booked the screen in with R&I , I was told that the local service agent will be making the decision what to do, not Pioneer, and they will not be replacing the main board, but will bench test it in Morley to find the actual fault. They would leave me a loan screen while they play with it. Well, they picked my LX508 up the very next morning, very fast service indeed, but advised ,me that as it turned out, they did not have a loaner TV to give me just yet (They dropped that off a couple of days later, an LG). R&I had the screen for about a week, and when I called to ask what was happening with it, I was told that they could not find anything wrong with it, and they would call me back later. The next call was to say they were bringing my LX508 back the next day. The screen returned and the gentleman who dropped it off spoke with my boss (Wife). My wife said that she hoped that the fault would be fixed anyway as they had replaced the HDMI main board as requested by Pioneer, the delivery guy said that nothing had been done with the TV, it had not even been opened up as it never faulted in the workshop. My wife and I just thought that he may not know what really had been done anyway, and we kept our fingers crossed. The second night of use the TV locked up again. I called R&I electronics back up and explained that the TV still had the same fault, and that all the time we had their LG loaner plugged into our system, that it had not frozen up, nor had our daughters Samsung Plasma that we had used over about a week plugged into the same system, they all worked as they should. The Pioneer screen was still showing the same fault. When I asked again if they had replaced the main board, the reception staff checked the records and said that the service tech had ordered the main board, but that this had not yet arrived from Pioneer, they suggested that when it comes in we may get a call from R&I asking if they can come to our home and fit the new board in house. So I waited another week, with no calls from R&I. I called them again, this time speaking with a different reception staff member who checked again, as told me that the main board that had been ordered was to replace on that had been used on my LX508. This had me wondering if it was a generic part, or why they would hold an LX508 main board if no one in the whole of Australia has ever had to have one replaced. To this, the reception member checked their repair records and advised me that their store alone has replaced four main boards on LX508's under warranty (I love being told bullshit, it makes me feel so happy). Anyway, the gentleman said that their service tech should come and look at my system as he had spoken with the tech while I was on hold, and the service tech suggested that it will be a cable error, or something I am doing wrong. So they booked a service appointment to attend at my house. A couple of days later. the service tech arrived, I made sure I got the day off work to be there for this one, and he asked me to go through the error history, and what I had already tried. He suggested that the Harmony One may be locking up and sending a single IR message which is holding the TV controls out, but then how can it still switch everything else on and off over and over as I am cycling the system waiting for my screen to respond, plus it will not answer to the actual Pioneer remote, but will respond to the actual button on the TV itself. I had also tried to put all remotes away in a solid drawer to counter that IR possible issue as advised by Pioneer during original fault diagnosis. He said it would be stray IR coming from any light source (We do not use lights in the theatre room), it may be an issue caused by Wi-Fi somewhere conflicting the IR sensor. I questioned him over the HDMI main board replacement, and he confirmed that they had changed the board even though they were not able to get the TV to fault prior to doing so (I am having trouble believing him now). He said that he was at a loss to explain what could be going on, and asked me to switch the system on and off several times over the next couple of minutes, and of course it worked fine. He also said that they do sometimes get people who call for warrant work on things that are working fine, and though it makes no sense, it does happen to them. Though insulted, I just stated that I do not see what benefit I would get out of wasting my own time playing a charade like this. He then said that he would contact Pioneer and explain what is currently going on, and get direction from them on what to do next. The next day, and I know this is not something that you should do, but when the screen locked up again, I pulled out the HDMI lead immediately from the rear of the Plasma, and tried my remote again. The screen responded to IR control straight away. It would appear to be HDMI related. I have tried just using the TV to watch free to air, without any HDMI inputs on the screen. Over about three days of use (And sick of watching adverts), the screen did not lock up once. I passed this info to the R&I service tech, and he said that this actually just confused him even more, he was leaning toward interference from the Harmony, or a Wi-Fi signal somewhere. Now, I am not sure what to do. It appears that I am at a dead end. Neither Pioneer nor R&I electronics have called me back with a next step. It is not like Pioneer can replace the unit, they don't even make screens anymore. I had thought about calling Pioneer again and pushing further, but where would that get me? My wife and I have been out looking at other 50 and 60 inch screens, and were have not found one to match picture quality of the unit we have now (Well, in our eyes anyway). To top that, when I was googling for faults and ideas on the LX508, I see that someone is selling a whole working unit on eBay in Victoria for $520. Damn that is cheap, if it is still in good working order without any screen burn in (http://www.ebay.com....=item20cb5faf12), so I guess that worse case they may suggest that the screen has a really low pro rata value anyway, never mind that they were selling for over five thousand when still being made. Damn it, if I lived in Victoria and not WA, I would buy this unit for spares at that price. Anyway, If anyone could stomach reading this war and peace, and has had a similar issue, I would be grateful if you could share your knowledge with me. Hope this was the right forum to post this one in too Mark Sorry, I said I was going to go on and on. P.S After speaking with the the man from Oznetics, and my concerns that cheap (under $10) HDMI cables I have been using may be causing issues for me (Not that I got them from him, I was just calling to ask what he thought of my situation), he was pretty sure that this had nothing to do with any HDMI cable I am using seeing as I have used two different sets of cables with the same error showing. But seeing as I was pushing to get a set of premium HDMI cables anyway, just for my own peace of mind, he was very kind and did me a very nice deal on a set of five. That man is a gentleman, plus he kept on trying to convince me that I did not need to buy any more anyway..
