AVS Forum articles Contests. Long time 32c45, first time poster. Using xrandr –output VGA1 –brightness 0. I’ve fiddled a bit with the user and hidden service menus. The first mostly contrast work to a degree in reducing the spectrum affected, and I don’t understand most of the second. Or what settings do I have to change to achieve the same effect that I get with xrandr halved colors to the less bright half so that it looks okay?
Here are a couple pictures. I have since fixed the issue I had with the native resolution being skewed to the left so that the left side was off-frame and the right 32lv45 had a matching black lv by changing the XGA mode. Last edited by fridelain; at I just know somebody is going to comment about the wrong resolution.
First of all, I’d stay out of the service menu.
There really isn’t anything you can do there other than permanently brick your tv. I would set the tv back to default settings and then get a calibration disk and try to adjust the basic parameters or what ever is available to you via the user menus. It looks like the tv is not a North American version so any service menu information you find may not be specific for that version, region, or even mobo version. Otto Pylot is offline. There really isn’t anything you can do there other than permanently brick your tv I did not touch anything that looked like it might brick it.
What I did touch I googled to make sure. And I expect that the fix, if any, will need it. Second thing, first tried with regular TV programming and the rainbow bars calibration screen a local tv station emits at night, then with the computer and www. I’ll provide any details if asked and am willing to try out any suggestions within reason. Problem is the same on all inputs, even internal like analog and digital tv. Halving the color gamut to the less bright half fixes it.
I can do that with a computer in software. Originally Posted by Otto Pylot. I’ll answer both of you.
It’s called the Service Menu for a reason. So what worked on one, may not work correctly on another, or the layout may have changed slightly and even entering a certain area and not leaving correctly can brick a tv. It has happened many times before. There’s usually nothing in the SM that will really help unless the current firmware has been borked somehow.
In that case one would have to know what the settings were when it left the factory as new and input them back in correctly.
If the tv is free, and you want to experiment with it that’s fine. No loss if you brick it. But I’ve seen folks take a brand new tv and try to enable a feature that is not enabled for their version using information gleaned for the internet and brick their tv.
If you are so bold as to enter the SM, do so very carefully noting the settings on each and every screen you visit 32lc4 if you click on something by accident, hopefully you can re-enter the data 32lv45 be fine. I 32kc45 tried resetting it. I googled and found the service manuals and how to reset 32pc45, as well as how to enter the service menu menu key in both tv and remote, takes a bit to show up, and regular 32lc445 will show up a while before Also, I wish fiber internet was an option in my street.
I never meant to imply that you 32oc45 clueless. Lots of very talented individuals have entered the SM with disastrous consequences. A factory reset is the first place to start but I guess that didn’t work in your case.
I wish you all the luck in the world and sincerely hope that you can fix what ever is wrong.
LG 32LC45 TV wrong bright colors. – AVS Forum | Home Theater Discussions And Reviews
Just remember that the service manual is one thing, but the firmware version on the main board may have different settings than what is listed in the general service manual. Were you able to get the right colors, at least at lower brightness levels as you hoped?
How does changing the backlight affect it? Originally Posted by johnfull.

First thing yo do is turn off any energy saver settings and brightness or back light sensors and make sure it is not in an energy saver or store mode Important Another thing to try is put the TV in Movie ,Theater or Cinema mode or as a second choice standard or custom or USER only and screw up the contrast or picture to max same with the backlight.
Contrary to popular wisdom contrast sets the white levels and brightness controls blacks. Excessive brightness kills the blacks and thus the contrast OTOH excessive color saturation skews the colors and softens the picture and kills details each panel and TV has it’s own limitations the trick is finding the sweet spot for that particular set.
Good thing to do is set HD. Only the very best expensive LCD 32oc45 most plasmas and ofc OLED displays can maintain reference black and adequate brightness at the same time what the objective here is ,is to find the best compromise Short of a professional calibration This clever Sony Color and Detail vs other HDTVs test file and or video is great for final fine tuning color saturation and brightness it works very very well.
As you probably know you can’t always get as accurate color on the web as you can with a downloadable file due to various browser browser rendering variations bandwidth 32kc45 and other thing you probably know a lot more about than I do. Also set color temp to neutral or gl never cool that skews colors and pushes blue warm can also do that and push red instead depends on the TV YMMV. Otto Pylot always give good info. PC monitors are usually much easier to deal with BYW. You can try RGB there are some odd sets now and gl that like that.

Hopefully this will give some starting points. Last edited by tubetwister; at Originally Posted by tubetwister. Originally Posted by fridelain.

Lowering the color gamut accomplishes nothing and does not fix the problem.

We may not be iT professionals but they don’t know much about TV’s as a rule some of us here are pretty adept and experienced at fixing TV’s and know more than a little about video signals and data take the advice or don’t it’s up to you. It would be nice to get that one running it’s got a well specced panel for it’s type and should be able to put out a very good bright colorful picture.
Other concern is panel or backlight running dim that panel should be a torch I wonder if the panel or backlight are dimming no firmware at Ly for that one at least where I looked maybe you can find an inexpensive mainboard on ebay and try that other than that I’m thinking panel or back light or backlight inverter but they usually work or don’t if the voltage is too far off it should fail to post much like a PC they both use switching power supplies.
How bright is it compared to a PC monitor it should be way brighter with that panel in there most PC panels spec less than half as bright as that one. In case you haven’t seen it yet it here is the owners manual like you said no backlight pg or low power setting either that wouldn’t fly here in US ofc most of us just turn energy saving off anyway not having one would be fine with me. Old drive had win 7 x64 and Just did a clean Win7 x64 and Ubuntu It had one of the the prior generation Seagate GB drives that I understand were failing early big time I can still get it to boot with ubuntu but the windows system partition is broken beyond repair bad sectors none of the usual stuff could fix it.
I was able to move my Windows and Ubuntu files off of it with the Ubuntu partition though so it’s all good it’s in a closet now in case I ever need to have an Ubuntu drive temporarily never know. Good luck with the TV keep us posted. I’m not familiar with Euro Scart. Other concern is kg or backlight running dim that panel should be a torch I wonder if 32oc45 panel or backlight are dimming no firmware at LG for that one at least where I looked.

You would need a DVM to verify it rail voltages are usually printed on PSU at the connector see which one are not ramping up or sagging. OR electrolytics on the backlight inverter board You can also shotgun it take the back off and look for bulging electrolytics on the boards that set is in prime age group for bad caps.
Replacements are inexpensive 23lc45 not at all difficult to replace.
Yes brightness does not control the back light as one would expect but it controls the transmittiveness of the LCD panel instead. Color will never be right without sufficient luminance brightness because it is a passive rather than emissive display. I’ve heard Linux Mint is the thing good to hear it from a pro now I might have to check that out thanks!
