Hello Everyone,

This is not an area I know an exceptional amount about. I have a TV, an Emerson LC320EM2F. I got it I think for Christmas in 2011 so it is about 2.5 years old now. While it only supports 720p or 1366x768 honestly, I have been running it at 1080p for almost the entire last 2 years. It only had a one year warranty.

Every since I got my Xbox 360 Slim about a year ago (I think) it has had some minor issues while playing games. Its a newer model Xbox but I figured it was just having minor heating issues still. It was just a flicker on screen. More lately it has been doing it more.

Over probably the last 6 months while using it with my PC it has also had minor graphical glitches also. Just a slight line across screen for a split second on occasions. My GPU is overclocked so I didn't think much of it. Then about two weeks ago it did it real bad in a game, so I closed out and it continued to do it while on Windows horribly, to the point of being unusable. Worried my GPU was messed up, I removed the overclock, and then underclocked it which did not help.

I switched to my integrated Intel HD Graphics 4000 and put the GPU in my brothers computer for the last two weeks. He did not see any issues. The screen stopped going crazy on Windows, and though it is now less frequent I continue to see the graphic anomalies on screen occasionally while gaming and general web browsing.

GETTING TO THE POINT
Sorry for the long intro, I am concerned my TV is going out. However, I don't really know what is failing on it. If it was a bad capacitor it would just be dead, same with a burnt out part. I am looking for any ideas how I might fix or prolong the life of my TV.

Please help.

Modern LCD tvs are not like the old tvs in the past where you can just fix parts, they are ment to be dissposible throw-away items.

Also the walmart brands like sanyo and emerson are bassically ment to be the TV you buy for $200 on black friday and then next year (maybee maybee two years) you are shopping for a replacement on black friday because it died.

There is nothing you can really do besides buy a higher quality TV.

Yea I was afraid of that. Haha and honestly I'm pretty sure it was bought on Black Friday for around $200. I figure I will need to buy a higher quality one, but just want to try to postpone and get the most use out of it I can. Perhaps if I rig a spare case fan to blow through it and help cool it down it won't act up. I never really thought about it, but it acts up worse when using Xbox typically, which is below the TV and blows straight at it.

Not sure this will help you but here goes the comment more on the general side, your TV has a physical pixel resolution of 720p as you wrote which is note the same meaning as what it "supports", as it seems from your post you are feeding your TV with a 1080p signal, hence it supports also full HD but you will still not see more than a 720p res.

The main problems as I see it, you will gain Zero and even get performance issue, why... first of if your xbox or pc has to process something to be 1080p instead of 720p which is a waste, both because it takes much more processing power to do so, and in addition your TV has to do extra work to down sample it back to the physical resolution of 720p, this in turn means all your equipment are burning away power for the crows and they, as any equipment, usually may perform noticeably worse when dealing with higher bit rate media content which can eventually cause glitches, but also the capacitors in all the power supply circuitries need to deal with higher power withdraw which is wearing on them, you get as a result Shorter lifespan on your products.

I am not acquainted with the xbox or whether you have tried the following, but if possible are there any settings for it to output max 720p, the same with your PC stuff.

Thanks for the idea and trying, but I think you are only half right. I think that from running at 1080p my TV is wearing down faster and using more power, producing more heat which is causing issues. The heat makes a lot of since cause its doing worse now its summer.

However while it is rated for only 1366x768, I can see a very noticeable improvement between 720p and 1080p. In TV shows not so much, but everything is different with the desktop, web browser, and desktop programs in terms of how sharp and fine printed everything is. In games its extremely noticeable usually. I think that maybe the parts they used are only meant to handle 720p but can actually handle 1080p, just wear a lot faster so they don't advertise it.

I am trying a USB fan on the vent by the power circuit now whenever I am really using it or it is really hot.

ahaa, you mentioned the quality differences in particular pertaining to your PC, technically there shouldn't be any down gradation, but I can think of a few reasons to this such as whether the PC can output an exact pixel map corresponding exactly that of the TV and this depends whether the driver can do it, secondly how does the TV handle the "PC monitor signal".. thirdly, in Wndows XP at least, there's something called "Clear Type" and this is specially tailored to fix the smudged look on LCD's, especially text looks noticeably worse if CT is not enabled, in the old days when CRT's were prevalent there were none of these problems, and probably there are some other explanations as well but we are then getting beyond the eventual inherent limitations of these devices which may not be fixable anyway.

I'm doing HDMI to the TV. I think before when I just tried VGA that it was locked down and wouldn't allow me to pass 1366x768. So maybe its some kind of bug that is allowing it to work on 1080p. Not sure. Though honestly if it does die you are right I have gone past what should be the limitaitons of the device. Honestly if it does die, its been worth it cause 1080p makes a lot of things look wonderful and its done well over the years. Hopefully the FAN will keep it going though.

HDMI.. yeah, that's a bit of uncharted territory for me, I have a very weak memory I read something there's some copy protection/downgrading of the signal handling between HDMI devices or so.. but one scary thing I read not too long ago is that it's suspected some manufacturers add a "digital bug" so the TV will fail sooner than later, it's all micro controllers these days so they can put any kind of less funny Easter eggs into it, don't know if it's true but just look at the Snowden case full of unimaginable revelations one couldn't be surprised at anything anymore in this digital junky world we are living today

Well I wouldn't put it past some companies to do that, but in regular HDMI or micro-HDMI that isn't the case. I have one a friend broke so I cut it up to use the wires. There isn't any micro chips inside.

I wouldn't put it past some companies though. They will do anything to make money.
