Back to ChromaPure:

Preliminary calibration done.

Service Menu White Balance, and TMX reset to Zeroes. Service Menu White Balance calibrated, followed by the 2 Point, then the 10 Point Calibrations. All this time, the 2 Point was the missing Key to my calibrations. the Gamma was alot better, excepting a peak at 90IRE, and problems from 30IRE down. Pulled up Calman which seems to get along better with i1Pro from 30 to 10IRE. The final PQ was better than any previous results up to this date. Big test was the evening News, National and Local. Both looked much better, especially the National Weather report, where previously calibrated with Calman, the Weatherman's skin colour was always reddish when he's up against that GreenBackground they use. Now the Flesh tones look more Natural. I usually let this run for several days, then go back in and fine tune.
Watched the Blu-ray `The Big Year' - lots of great scenery, and fleshtones. Beautiful! (Also a good story!)

Will fine tune this weekend to see if I can iron out a couple of problems, then post the results

Have nixed the settings for now, since we're still have on going changes on how this set is being calibrated. Will say this though, this set is getting to be more and more amazing with each new (And sometimes old techniques that we've forgotten about since they didn't work then, but do now with newer programming software, meters, and techniques.) calibration routine we come up with.
Konica Tech and I will be getting together in the next little while to knock heads, and hopefully end up with a final way to calibrate this magnificent TV! (But don't bet on it that something different will pop up!)
2 new calibrating software updates coming in the near future from both ChromaPure and Spectracal. Of course, we when then start all over again - isn't calibrating fun!?

Got a problem. I mentioned months back that I thought my LG BH200 was screwing up by making my picture go into a slow motion-like stutter(usually about 3 sec long). It would happen every 15 or 20 minutes into a blu ray movie. I am not getting this effect during directv viewing or on my dvds(atleast I havent seen it yet). So im thinking its a 24p thing with the lg media box(god, I hope its not the tv). I don't know for sure, but i'm out of theories. I switched hdmi outputs and switched out my BH200 for the PS3. I've been looking at the DVDO Edge(ISCAN out of price range), maybe hoping it could solve this issue. I'm just really hoping its the media box and nothing else. Any advice is much appreciated. Other than that, my girl is beautiful.

Try going Direct to the 55LHX with the LG BH200, by bypassing the Media Box. (Got rid of the Media Box, back at the beginning - didn't like what it was doing to the PQ.)
Do you have and AVR with HDMI inputs, then try using that with one feed to the TV. (Also makes that you now only have to setup one 55LHX HDMI Port.)

Thanks brother, i'll try it tonight. And no, I have no AVR at the moment. Was looking at the Pioneers,Onkyos, and the DVDO Edge. They are all in my $400 range.

Just got the wife the Yamaha 473 for her 55LHX. Now I do only use it for the Audio, since every thing feeds into an iScan Duo. But it's a nice little AVR. Check it out.

It worked. I'm going to test more tonight to make sure.

Did you find a better PQ going Direct, versus going through the MB?

My pans were way better. The overall pic I have to look at again. I've been on nights for a while and i'll be able to get at it tomorrow night.

I am flipping out on this not so intelligent wireless box .first my hdmi outputs went out and Know my antenna tuner went out cant watch tv .I think the box is to intelligent that my tv is not able to communicate with it .Does anybody know how I may fix the problem .have been researching can't find nothing out there:mad:mad.gif

Media Box:

I think the majority of owners ditched the MB, and instead use their AVRs. Some of us are using the iScan Duo as well. Leaving the AVR for Audio only.

Hi all,

I may have an issue with the green channel on my LG 55LHX ;(

I fully calibrated my LG TV two years ago (using my iDisplay LT and ColorHCFR - grayscale, color, etc...) and everything was great until recently when I thought I felt like the image was a bit more red / pink..... well, armed with my good old iDisplay LT, I ran a greyscale measurement and hold and behold => my greens are all down by 30% (across the entire IRE: 10 to 100).

Before I had pretty much 100% Red, 100% Green and 100% Blue and now I am at 130% Red, 80% Green and 130% Blue.

I tried to play with the IRE gains to rectify that, but the values where just becoming insane and did not fix the issue (-35 Red, +30 Green, -30 Blue for all IRE).... so does it look like I have a busted TVs (or board) ;(

I have also tried the other video modes (THX, Standard, Vivid, etc...) and they all show the same symptoms (low greens in the 80%, and red / blue in the 130%). I have checked my iDisplay against other calibrated units and it is fine.

Of course I am out of warranty, so should I try a factory reset (and how), or any other ideas?

Thanks a lot!

See if you can pick up a copy of either Pixel Protector, or Disney WOW. Pixel Protector (Blu-ray) has what they call Pixel Washes. First wash is run for 6 hours, the second for 2 hours and the third, for 1 hour. This cleared up my Red Service Menu White Balance Warm problems. The Disney WOW has what they call, (racking my brain here) Flicker test, or something like that, that is essentially like the first wash on the Pixel Protector.
TVs do change values as they age, I re-calibrate mine every month. Originally - Service Menu White Balances for Cool, Medium and Warm were way off LG's specs, and I was trying to compensate using the IREs! Purchased the Service Remote, and now do the Pixel Protect Washes, followed by the AVCHD 709 Disk to setup the Brightness, Contrast and Colour. Then calibrate the Service Menu White Balance Cool, Medium and Warm. Following this calibrate the 2 Point, followed by the 10 Point, followed again with the 2 Point, then a final 10 Point. Then move on to the CMS.(All after letting the set warm up for 4 hours.(Good time to do the Washes))

Originally, my sets had Blue Rising. Now that they're aging, it's Red Rising.

Hint re the Service Menu White Balance: set Green Gains for Cool, Medium and Warm to 192, then adjust the Blue, then Red to get the required values:(Don't go over the 192) Cool: x=0.269, y=0.273 Medium: x=0.285, y=0.293 Warm: x=0.313, y=0.329 using100IRE setting. RGB Cuts - same values as the Gains, but using 30IRE setting.

Thanx a lot for your help - I will see if I can get a copy of that disc and I will then do the wash. Hopefully this will bring my greens back up since I could not correct the issue with the IRE when I tried yesterday ;(

I will try again to play with the IRE at 30 and 80, but did not seem to be able to bring the green back up enough... hopefully the wash will help.

Thanks again.

PS: what do you need the Service Remote for?

Also, do you need to be in the service menu to access these settings? Right now I can only change the RGB brightness / contrast from -50 to +50 thru the regular menu (but not 192)...?

What I also noticed was that gamma is completely off right now and that this issue is non only present in my Expert mode but also in ALL other modes (vivid, etc....) - hopefully this wash you mentioned will help

Thank you,

FYI: attached are the 2-year ago calibration results vs the results today - you can see that the gamma has gone crazy !?!!

TODAY (grayscale and gamma curves):


2 YEARS AGO (grayscale and gamma curves):

Another question: how do you bypass the media box?

If I try that and have my AVR plugged in the TV directly (it goes to HDMI5 this time), the "menus" and most of the remote buttons do not work anymore. It will be hard for me to calibrate that channel without the menus

Am I missing something?

Thanx!

I'm getting an AVR soon and would like this knowledge as well. Also, to all, just bought a screen protector(made out of lexan) recently because of the kids. It looks unbelievable to say the least. I thought this thing was going to screw up my color, but needless to say it gives the tv more pop. It gives the glossy look. It looks not so great in the daytime, because of the velcro(and glare) that you can see. At night though, it's a different story. You can't see the velcro or where the screen protector begins. It looks like a VT50 with the one sheet glass design. It's not for everybody. But for people that have kids, especially autistic ones, this sucker is for you.

My Media Box was replaced by an iScan Duo. Previous to this, my Yamaha AVR, but it was lacking HDMI inputs.
The iScan Duo also gives me my Greyscale and CMS calibration Patterns. (Alternates include the INNER Screens or the AVS HD 709 DVD. ) You lose some of the Media Box extras, but you now only have to concern yourself with one Input.
I noticed in your 2 year difference pics, your set is doing the same as mine. Green has pretty well stayed the same, but Blue and Red have risen.
As previously mentioned, the 55LHX Service Menu White Balance specs where nowhere near to LGs required specs! You HAVE to get the White Balance to spec before calibrating!
You can do as Nony does and go though the cheaper Serial Port entry, but this is a complicated process versus the more expensive Service Remote route:
http://www.newremotecontrol.com/lg/catalog_item.php?catnum=105-201M
We also found the 55LHX screen does not have a linear quality across the panel. Have now mounted my meter on a tripod and about 1 foot away from the screen to try to give a more average reading.
Have NOT lost any required calibration Remote Functions switching out the MB.
I calibrate only the THX Mode. Expert 1 and 2 are zeroed out. Colour turned down to Zero on all Modes excepting THX. Found too much interference affecting the THX mode, if values are manipulated in any of the other modes
You calibrate the 2 Point First re RGB Contrast (100IRE) and Brightness(30IRE). Now switch 2 Point to 10 Point. Now you have the 10 to 100 IREs to calibrate.
Edited by p5browne - 9/26/12 at 9:24pm

Thanx a LOT! I just ordered the remote and I will play with it, following your advices about setting the gains for green first then blue / red on 100 IRE and then moving on to 30 IRE.

Would you have a copy of the manual though or some link where they explain how to use the remote and do these changes? hopefully, changing the gains will not screw up my gamma completely

Thanx again p5browne! I really appreciate it...

btw- There never was a valid reason to order/build/buy a service remote control. And that is because the two/three commands INSTART/EZADJUST/INSTOP have always been available (yes always) in the user interface. It's always been called "Keyboard Test Mode" and it looks like this -

=================== [ UI Keyboard Test Mode ] ===================
'0' ~ '9' : Number Key, '-' : Dash
',' : Vol.Down, '.' : Vol.Up, '>' : Ch.Up, '<' Ch.Down
'[' : Up, '/' : Down, ';' : Left, ''' : Right
'M' : Main Menu, 'H' : Home Menu, 'X' : Exit, 'I' : Brief Info.
'B' : flashBack, 'A' : SAP(audio), 'U' : Mute, 'P' : Pip
'R' : Ratio, 'V' : Ext.Input, 'C' : Caption, 'F' : favorite
'D' : DW TS, 'E' : HDMI_CEC, 'G' : Guide, 's' : INSTOP
'K' : In start, 'L' : Adjust 'N' : NetCast, 't' : Return
'T' : Teletext, 'O' : T.Opt
[ESC] : UI Keyboard Mode Exit
=================================================================

Notice that you if you press -

K- you invoke the Instart menu
L- you invoke the EZAdjust menu
s - you invoke the INSTOP menu

and this has always worked across all LG platforms (both MSTAR and BCM)

This means that you don't have to invest in -

1) a service remote control
2) a universal remote control
3) a custom IR transmitter

This applies to all units worldwide without any exceptions..

-nony

Nony - it's all well and good that you're well versed in using the Serial Ports and all the commands involved. For those that do not have the proper serial cable, this is over the heads of a lot of Forum members. For the cost of the Serial cable, you're already 25% towards the cost of the Service Remote Controller..
Therefore Serial Cable cheaper but more complicated to map through everything. Service Remote or getting the IR Codes for a current Remote Control may cost more, but is easier for the average Forum Member to figure out. (what do they call this - oh yes, as easy as pushing a button!)
Edited by p5browne - 9/29/12 at 7:54am

Most people appreciate options, and then they can decide for themselves what route to take. There is nothing complicated. You just have to be able to follow a few simple instructions. As you may recall, my serial cable cost me $4.00. If your computer doen't have serial ports, you may require a USB-to-serial adapter ($10-$15).

Comes with the iScan Duo to attach to my laptop for calibration purposes.
How are the Service Menu White Balances handled? With the Service Remote, just click up and down to change the values. With the Serial cable option, do you manually have to keep inputting new values?

Not if you don't want to. For someone who does not have a service remote (or equivalent) they could invoke InStart/EZAdjust from the Keyboard Test Mode, and then use their regular remote to navigate and change settings.

Should you delve into the debug menus, you may find some very interesting calibration/pq related menu options - and you really want to back up your firmware before you start dabbling. Backup procedures can be found at openlgtv.org.ru.

-nony

Has anyone tried a Darbee unit on a 55LHX yet?
With the new Calman 5 and Spectracal C6 profiled off the i1Pro calibration, both my 55LHXs now just look amazing! For the first time, I even got a compliment from the wife as to the fact!
3 years to get here, and I wouldn't trade this set for anything! The 55LV9500 calibrated, looks amazingly similar but with more Pop, but the 55LHX beats it out in the Blacks! Good place to notice this is on the AVCHD 709 DVD when doing the Brightness pattern: Totally Black in the background on the 55LHX, but Greyish Black on the 9500.

What pannel do you have on the lv9500? L or W?

How am i gonna know if my panel is L or W?

Check the Service Code on the label at the back of the set. My last 4 digits are WLHR. I think most people ended up with the W. If I remember, the other letter was Y, not L.
