This just happened now. I'm currently using a tv as my second monitor via hdmi. Haven't gotten any problems until now. I just noticed that my screen became this

Looks like green is missing. I doubt that the hdmi cable is at fault as there are not separate wires for R, G and B (other than in a VGA cable). My experience is that a faulty HDMI cable will result in no picture at all.
However: have you tried an alternate picture source (e.g. directly from the TV receiver, from a VGA or DP input? If other sources work o.k., the fault is with the HDMI input. or the HDMI output from your computer (have you tried another monitor?)
If other sources show the same issue, the problem is probably with the driver board for the LCD. You may be able to replace the driver board by another board. Replacement boards are easily available if you knw what type of LCD you have (driver board and LCD need to match). Google "replace LCD driver board"

Even when my tv is on another source or when I completely remove the hdmi cable it's still like that. Btw I really appreciate the help
