We have am LG lcd 42" tv 42LC2D that's just over 3 years old. It's had a problem since it was just out of warranty. Green staticy snow appears in dark areas of the screen, so it moves depending on the picture. We tried to contact LG to give us assistance, but no luck. We had it in and out of the shop three times now, with no results. The first time the power supplier and digital/analog modules were rebuilt. This did not do the trick. Next time the main video control module was replaced. This did nothing. He stated it was okay but when it was home and plugged in it started again. The third time I think nothing was done. He just had it plugged in and he stated that it was okay. We noticed on this site that people have had similar problems with plasma tvs. Seems it was a voltage problem. The back of our tv is off, but I can't see where to adjust the voltage. Is an LCD similar to a plasma? Dunno what to do next, just maybe bury it (may it rest in peace)
Help anyone?!?!?!

Is this on Digital signal? I know that our Sony 40" gets something similar, but only on analogue signals, it's normal and just general signal noise. Have a look through the options, see if there is some sort of noise filter or somesuch. Apart from that, I'm unsure unless it's analog signal, and I have an LCD.

I've never heard of the problem you're refering to with plasma TV's but I have a general idea of what you're talking about. Lets cover some of the basics.

Plasma TV's and LCD's are flat screens. There the similarities end. Plasma uses heated gases where LCD's use pixels to block certian wavelengths of light.

What you're describing sounds like something we call artifacting. It's usually a byproduct of a poor digital signal. Basically it's the digital equivilant of snow. If this is an Off The Air recording I'd check to make sure you're using a high enough gain antenna and that it's oriented properlly for your area. There's a couple of sites out there that will tell you where your local transmitters are in relation to your home for orienting the antenna.

The next thing to check is to make sure you're using a good power filter, not just some cheap power strip from your local Wal-Mart. A good power filter can be had for as little as $50. I recommend, and personally use, Tripp Lite products which can be had for that price range.

If cleaning up your input power doesn't help your last option may simply be a crappy cable. I'd try replacing it with one from MonoPrice which is who I buy all my cables through. They're inexpensive but extremely high quality cables. The only downside is shipping times can be pretty bad depending on how far away you are from California (7 days to St. Louis).

sounds sorta like the issue i had with the blue dots on my Philips TV that went away after a voltage adjustment.

You certain there is no place for adjustment? Usually there is a place to adjust it on a Plasma as they set the voltage on each one before it leaves the factory last I knew.

I don't know about that, Dan. He only says LCD once, right at the start and then proceeds to call it a plasma thereafter.

The other times he mentioned plasma, he was saying about how he's seen plasma TV's with similar issues.

Dan

Fair enough. Has this issue been resolved or is there still unsurety as to the problem?

Has anyone thought about changing cables? It would be worth a try. My next suggestion is to let the service provider give it a try. You never said how you get your picture, ex; cable . Does it happen when you watch a DVD?

I guess no one read my post at all.

If that was actually the case then the problem would most likely lie in the cables or power conditioning as Shamroc3 stated since that would be the only thing different from plugging it in at home.
