LG Plasma Blue Haze

I have a Hitachi 53" plasma TV about 2 yrs old now and the picture is still great, but anything plugged into the input doesn't have any sound. Sorry I can't help but, I thought I would let you know you're not the only one with plasma problems. Good luck.

Just some thoughts -- There may be some aging of the pixels occurring, where blue shows the aging first; or that the compensation circuit for the aging wasn't quite right. Have you run a color adjustment via the monitor's set-up menu? Perhaps by decreasing the blue channel setting the problem will go away. Or perhaps run a contrast and brightness adjustment? It may be that the video black level offset needs to be adjusted (similar to brightness offset on a CRT).

Since there is no shadow mask, like in a color CRT, I don't think there would be any need for degaussing. You could tell for sure by holding a magnet near the screen to see if the image or colors get distorted.

My friend owns a sport's bar that dropped a 48" plasma tv off it's mount, and it developed the strange bands and pockets of "black holes" that you may be experiencing. I doubt if it is specific to the manufacturer, but to the nature of the beast. The above link is a pretty good example of what we needed to do to get rid of the problems. In spite of having the top 20% affected, it came back to darn near 100. I found that hanging it upside down whilst torqueing the corners worked best.

Standard caveats apply to this answer, and a final caveat: HD tv's are the only products that I can think of that warrant buying the "extended warranty" on.

I am looking at tv's now. So would you recomend lcd over plasma?

I would recommend LCD's if for no other reason than the plasma sets are huge energy hogs by comparison. The image quality differences I see so clearly are when comparing my 4-year old plasma to new LCD; I don't know if new-vs.-new would show the same 'gap' in image quality. When I first had mine installed, we got all the usual 'ooohs' and 'aahhhs' from friends and neighbors. "It' like they're right here in your living room" was a common reaction. While the image is still good, and beats old CRT-type tv's handily, no one says that anymore about our older plasma, but we do say it about the new LCD's. So in addition to the energy penalty, plasma's may show obvious deterioration of quality that I'm not sure is (as?) evident in LCD's. Would any LCD set owners care to opine?

Anyway, only your own eyes can determine whether one type set's picture quality is superior to another and, as usual, I would be cautious about drawing conclusions at the retailer. Each manufacturer has parameter settings designed to make their sets 'pop' when in a store. On top of that, savvy store managers might have tweaked a 'weaker' set even further to try and move it out of inventory. Check their settings (brightness, sharpness, contrast, color level, etc.) to see if one set has been 'cranked' beyond its competitors before you shell out $1,500 or more.

Plasma screens have a limited life. Good ones last longer. Like Gentlemen!!!

In the last 4 years or so, LCD screens have dramatically improved in quality, particularly with regard to black. 4 years ago 1000:1 was considered good, today its like 10,000:1 with some sets going even higher......

Also, the "shadow" has been fixed for all the screens that I have seen over the last year or so, which was what I hated about LCDs......

When you bought yours, plasma was the best, but today.......
