There is a sticking image on the screen, a faint outline image. Its a Plasma TV btw.
Its especially more distinct on a blue background. Is there any way to get rid of this ?

Sounds like image retention to me, maybe run a burn in removal or leave the set on a raster for a while ?

I think it is, I can see a faint text "LIVE" on the screen and some other things.
I don't know how to run a burn in removal and also I didn't get the raster one. Can you pls tell me more ?

there are some youtube videos on this where you can play a pure white screen for a few hours which is supposed to remove the burn in not sure if it would work though

They will vince, but you want it to be full screen not 16:9 etc, or moving/flashing colors will work too. It helps wear the phosphors a little and blend them back together so image burn doesn't stand out as much.

If its only light image retention, it will clear fast but if heavy you will need to run it for hours.

Update : I ran the video for 1 and half our. I can't see much difference. I noticed TV was extremely hot. I don't know if it is because of test or it is always like this. Thank you anyway.

I did adjust the Zbias and others, nothing changed.

Keep Zbias at what the panel says, also they do run hot its normal for Plasams as the Psu and Sus boards use well over 400w.
