LG PC3RV Panel problem

I bought an LG 42PC3RV in Dec 2006. I have never realised this problem until yesterday night when I switch off all lights and left my TV idle (without signal).

To my horror I saw what seemed like half screen burn in. But after reading this forum and others, I think it looked like uneven contrast across the screen as seen on these pictures. As you can see, the contrast on the right seemed higher while the left seemed lower.

On broad daylight, you'll notice nothing while during the night if you turn on the adequate lights it's almost unnoticeable.

Please comment and see what you think. Anybody had this problem? Is this normal on a plasma TV?

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

SOURCE: plasma burn,

Hey gallagher1,

While what you're seeing may be image burn, it generally only occurs when the same images are displayed on a screen for a prolonged period of time. Static images like letterbox formatting, banner scrolls (from TV stations like CNN), test patterns and the backgrounds from some video games have all been known to cause image burn, but most retail stores should know to take precautions against this kind of damage in their display/open-box models.

To make sure what you're seeing isn't simply the residue from an adhesive sticker or placard, I'd first suggest cleaning the screen with a damp, lint-free (microfiber) cloth. Make sure to wring any excess water out of the cloth before wiping the screen, and never spray water directly onto the screen's surface. You may also want to try using a commercial TV screen cleaning kit, but remember to never use household cleaners like Windex or Goo Gone on the screen as they may cause damage to LCD and plasma displays.

If cleaning doesn't help, this specific model appears to be equipped with a feature called Image Sticking Minimalization (ISM). According to information provided by the manufacturer, you should be able to access this feature by pressing the "Menu" button on your remote control and selecting the "Option" menu. Under "ISM Method" there should be four different options: Normal, White Wash, Orbiter, and Inversion. Each of these methods slightly alters how images are displayed to prevent - and possibly remove - any kind of image burn.

If you're not quite sure how to use these features, you may wish to refer to your owner's manual documentation. You should also be able to find step-by-step instructions on how to use ISM by visiting the following webpage:

Hope this helps you out.

SOURCE: plasma burn,

HI, I've just recently bought an LG 42" Plasma, and I am using it as a computer monitor.
I have noticed some image retention / burn, and I am hoping it disappears, but its now been a couple of days.

I am going to try the ISM methods, hopefully you guys know what your talking about lol.
Just wondering if there is anyone out there who has successfully burnt an image in their screen, and what results from that.

I have read that screen burn isn't covered in the warranty, I think it's important people know that.
Also the ISM methods are not automatic, its default is normal, and will have to be changed.

I am currently using Orbiter, is this the best mode for prevention?

Thanks for your help.

Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

SOURCE: Lg Plasma Display settings keep switching

When you boot up your tv for the first time, you get to choose between home and shop-mode.
In your case, he TV is set to "shop-mode".
Then it will go back to factory settings after 5-10 minutes. (so that customers won't mess up the settings all the time)

So change the settings from shop to home, and your problem is fixed!

We bought a new LG 32LD460 tv this morning. It switched on fine and we had it running with good picture and all. Then we left it for a while and came back to try and set up the xbox. It switched on with...

It sounds like a powere supply problem. You will need to take the back off and test the voltages that are printed on the power pcb with a digital multimeter. Need to check the power button light, if it is on then you have the 5VDC standby power and the issue might be the main board. I will do further research on this problem.
