NANO LG LV9500 Official Owner's thread - Page 51

thanks! meguerra

I don't think that's correct. It's got a BMIPS4380 CPU which is dual-core. I've seen it in /proc/cpuinfo.

jvolkman is correct it is a dual core chip. Not sure where the BMIPS4380 is showing up. I don't see it in the service menu or the service manual. I only see the BCM35230 in the " In Start" page in the service menu and on page 24 in the service manual schematics diagram.


http://www.broadcom.com/products/BCM35230

I'm pretty sure BCM35230 is name of the whole system (on chip), whereas BMIPS4380 is the name of just the CPU portion. It'll be shown in /proc/cpuinfo or kernel init logs, probably.

so did someone find out why Australian version doesnt sync with glasses and how to fix it ?

Not that I know of. I actually sent an email to LG asking if they'd be willing to divulge. Needless to say I got a rather typically unhelpful response. Disappointing in a way, as it's not like it's a model still for sale. Would probably need to know someone within LG, however I doubt there are any actual techs or engineers in AU and setup would be done overseas, leaving a bunch of brainless morons running the local arm with performa email response templates.

I dropped the ball too!

Let's finish the job. Next steps:

1) Detemine if the 3D sync signal is present when the set is in 3D mode.

The 3D Sync signal is a square wave on Pin 12 of the emitter connector and measures 3.32V p/p @ 50/60 Hz (or 1.66Volts with 3D, 0Volts without 3D), as documented in the service manual for the 55LW9500-TA. (Should only be attempted by a qualified tech.)


2) Let's get a proper dump of a) NVRAM and b) system startup in debug mode. (This is easy, once you get into debug mode, which is also easy, if I walk you through.)

Any volunteers for step1? step2?

Are you still in?

-nony

More testing is required to determine what configuration changes are required to enable 3D.

-nony

In reality, no-one has ever followed through with the most basic set of procedures for determining why the emitter is not transmitting a suitable sync signal, although many have participted and put in a considerable amount of time - myself included.

Here is what we know based on testing to date:

1. AG-S250 glasses work on Australian 2011 plazmas.
2. The speculation that these glasses don't sync up on Australian LCD sets because they run at multiples of 50Hz (vs. 60Hz in the US) is wrong - as I have concluded from my testing (where I forced 50Hz frame rate sampling on my set, and my glasses continued to sync up (with periodic pulsing, but they synced up).

The two probable causes for the failure to sync are -

Case 1. The sync signal is not present at the emitter.
Case 2. The sync signal is detected at the emitter, but the emitter has not been programmed/activated to produce the required RF sync pulses.

In either case, the problem may be due to misconfiguration, and if true can be easily addressed, possibly by flipping a bit in NVRAM/EEPROM.

Note: It is not necessary to downgrade your software (or invoke Power Only mode) to -

a) get a command prompt,
b) change from RELEASE to DEBUG mode,
c) dump NVRAM/EEPROM


-nony

Ill cop that. I cant really expect other people to do the work, although tbh I dont care much for 3D. Ill have a scan through the thread and figure out how to do NVRAM thing (nfi what that means). I have a service remote if that helps Also ill pick a pair of the ag-S250 glasses up to test.

I'm still lurking and still complaining of a lack of spare time, lol, but I should get a chance to look at it this weekend. I'll have to make sure the glasses are charged!!

I'll double check the instructions I have for the dumps, but I seem to recall that there was an issue with accessing the console using the mc 00 88 command rather than accessing it via the debug mode, specifically after initiating the logging, then restarting the panel the output was lost.

Alas Step 1 is beyond my capabilities and/or willingness to kill my panel, but Step 2 I can definitely assist with.

Nony, can you elaborate on this?

Note: It is not necessary to downgrade your software (or invoke Power Only mode) to -

a) get a command prompt,
b) change from RELEASE to DEBUG mode,
c) dump NVRAM/EEPROM

The only way i've been able to get debug mode previously was to go to power only, then set it via the in start screen. Is the MC 00 88 command what you're referring to here, or is there another method?

There are other methods.

Both of the two previously mentioned methods for getting a debug command prompt should have worked for you -

1) MC 00 88
2) System 1 Baudrate-->115200; System 2 RS232C Control--> On

If this is still the case, the method for changing debugStatus from RELEASE to DEBUG should be trivial.

-nony

ausdavep,

We should be able to work this through if our efforts are better coordinated.

-nony

The workload will be significantly reduced if someone completes step 1. Perhaps a techie can be recruited from an aussie forum e.g. whirlpool, etc.

-nony

Cheers Nony. Got my 3d glasses on Friday, and I'll test to reach the same point as the other AU owners, then read up a lot to understand what is going on and how to use the service menu and consoles, then hopefully provide positive assistance.

Good. The procedure for going into debugStatus mode has changed, and is not publicly documented. PM me if you want to schedule a real-time walkthrough.

-nony

arkasi55,

In the meantime you may want to ask for assistance here - http://openlgtv.org.ru/forum/viewforum.php?f=9 , so we can engage the developer community and I will respond to your post, to get the ball rolling.

Does anyone know how to calibrate the Service Menu 10 Point White Balance? Have changed the RGB values, but the calibrating meter never changes, nor does the screen. Screen stays at the Zero settings. Are you supposed to install your calibrated values from the GreyScale calibration? Nothing in the Service Menu about this either.
The THX setup as mentioned to me by Nony, is in the 55LV9500 Service Manual as well as the Service Manual he referred me to.

Senior's moment there - corrected by removing. Thanks

3D stills for testing-

Most of the 3D stills (.MPO files) from the following site should automatically trigger 3D mode and render ok - http://3dmedia.com/gallery/
Simply, download, and transfer to a USB drive/stick.

What time zone are you nony?

EDIT: Ignore that. Just realised we have been through this before.

I would like to know if you would be happy to RDP or SSH into my setup at home to give me some assistance. If so what time would suit you?

If this has been covered before, I'm sorry... Does anyone know if LG has exact (inferior/superior) replacement panels for the 55LV9500? If so, is there anything the tech could do to inhibit my ability to get 3D? If not, would the replacement screen alter my ability to open up 3D? I am scheduled to have my panel replaced before the warranty expires. I am having issues with light fanning out into the screen from both sides of where the screws attach to the panel. I haven't activated the 3D, as I can't see ponying up a lot of $$$ for the6 pairs of glasses my family would need! I would like to keep the option, however. The 1st tech just wanted to replace the panel, sight unseen. The 2nd tech wants to bench test, so I would like to know what would be the best solution to keep my 3D and my incredible viewing experience!

First of all, I want to thank all of you who have contributed to finding the deal for the 55LV9500, finding out how to enable 3D, which glasses to use, posting your calibration settings, and showing great support across this forum. I was looking around for a great full array 2D TV which was on par with the 55LHX and through your help, not only was I able to get a one with quality superior than the 55LHX, but with the best 3D current technology can offer.

Sadly though, my 55LV9500 has developed a defect in its panel. I have splotches of discoloration, about 1-1.5cm in size, across the entire screen. These are hardly visible in high noise scenes/images, but are visible in those with uniform color, especially so in whiter and brighter images. A technician affiliated with LG stopped by to inspect the panel and from looking at the imperfections on the screen, determined the panel to be the cause of the defect, the only resolution being to replace it. It turned out that LG does not have any more spare panels for this particular model or spare 55LV9500s to replace mine with. They have offered to either refund me the purchase price of $1600, or a replacement of a different model. They have suggested the 55LM8600 or any of their other high-end TVs. (I think the 55LM9600 would be a comparable model since it has a full-array panel.)

I would greatly appreciate any suggestions on whether I should go with a replacement LG TV of a particular model, or use the refund towards another brand. My first objective is to have a great, full-array LED TV (I use it as a monitor the majority of the time and am worried about the possibility of burn-in with plasma). The next requirement is high quality 3D. I am not an avid gamer, but am somewhat of a movie junkie. I care little about a TV's internet capabilities. I would rather go with active 3D instead of passive, since it offers greater resolution and image quality. I could go with the refund and wait for another TV within my price range, but it seems the deal on the LV9500 was a very rare event.

Again, I can't thank everyone enough for their support, especialy nony, videkid, p5browne, and konica tech to name a few.

That is simply not true. They are required to provide spare parts during the initial warranty period. Demand a replacement panel (or the panel variant), and escalate with HSN and LG as necessary. The identical panel has shipped throughout the world and can certainly be ordered by their parts department. In the highly improbable case that LG's global supply of brand new panels has been exhausted, they can always provide you with a refurb panel (refurbished by LG Display, and often better than new). Consider that they no longer produce a comparable model and accepting a refund would be a hardship. Also note that the consumer protection laws in your locale uncategorically trump the fine print drivel of your warranty.

If you accept anything less, you are being ripped off, and are making it easier for them to rip us off as well.
