The Technical term for image retention in LCDs is called "aging mura".
The more you leave the TV on, the higher chance of getting aging mura and image retention.
All LCD manufacturers recommend turning the TV off for at least 4 hours a day. This gives a chance to the transistors to "reset".
One way to remove image retention is to constantly play "random" video that exercises all liquid crystals.

Burn in does not happen to LCD screens. They do sometimes have image retention though. Image retention will look like an image has been burnt into the screen but 20-30 minutes of normal television viewing will get rid of this.

LCDs don't get burn in the way CRT screens do, mainly because LCD screens are plastic and CRT screens are glass (and because of the way the image is created). How long was the same image on the screen? It'd have to be on for a VERY long time in order to burn into the plastic of an LCD screen; I doubt that's the problem. Are you certain it's an LCD screen & what does the screen look like right now?
We need more info to answer the question.
The cause of burn in is having the same image on the screen for a long time. But that is with CRT glass screens - the image literally gets burnt into the screen over time. And yes, it's permanent when that happens to a CRT screen.

Unfortunately image burn is permanent. It is caused by the same image being on the screen for a prolonged period of time. Check with the manufacturer of the TV to see if the warranty covers the problem. The only way to fix it would be to replace the LCD screen

you get a "burn in" when something on the TV dose not change or move such as the HUD on video games.
ps HUD means Heads Up Display
I don't think that LCD can get a "burn in" i know good old CRT and plasma get then though
