So as I said I'm looking only for explanation.

On my 43" TV I have flickering line at the bottom, for about..let's say 2mm height. It's visible on bright colours while on black, including TV menu it's not visible at all. After 2 hours of working every morning that line is gone completely but until then it's there.

That line even though it flickers looks like transparent a bit disorted image of actual background which is happening in that particular moment. Is that a known issue among LED tv's ?

There after about 12 hours of running yesterday, now after 15 minutes it's already showing up and dissapearing.

P.S Don't ask about warranty and replacement, company in my country which make these are idiots and they are replacing fault models (i did replaced this one 4 times so far) but I gave up from that. I just need to know could this be worse ?

You have a problem of the flexes cables inside or the connectors of the data boards which connect and generate signal to the LCD panel. If this flexes is not connected or cold solder of the circuit board connectors this will result a vertical lines or horizontal lines depends of the sections of the board. If you know how to open that monitor, do it and you can check by pushing the flexes or like a ribbon cables. It will change the color display or distorted color. If this happen you can reheat using a hotair to fix well the connectors of the flexes connectors. If you can't do this, you need a service technician to do this or contact your supplier of your monitor.

Can this issue spread and create more lines ? Just wondering since I'm not making huge of a deal from this since my TV is on for 12 hours per day average atleast, so I don't see line over day but every morning I start thinking about that again and again. If in theory that shouldn't spread I would just leave it for now since this is first time that I got 43" TV and I'm having fun on both gaming and hd channels.

Thanks for that explanation though ! Much appreciated.

The best thing you will do now is to contact your supplier, since you don't know how to check it. There are consideration when talking the situation of the display. Because its a system board, it depends to the faulty parts, when or how it produces the problem is a certain of times. To avoid the more faulty parts and big budget, call or bring that tv to the service center experts for trouble or that Tv Monitor.
