TV screen not working properly (Possibly humidity issue).

Hi,

My Sony 65" X85C randomly started doing this the other day.

The sound and other functions seem to be working fine, there just isnt a picture showing on the TV.

I assumed it was due to some sort of water damage from the humidity. There have been rainstorms going on for the last couple months so it has been constantly humid. The first day this happened, i left the TV on to try and evaporate the moisture using the warmth of the TV. This seemed to work and the TV began working as normal again. However on subsequent days this is no longer working, and the TV is permanently like the attached picture now. When I turn the tv on i can see different parts of the screen lighting up in a similar fashion so I know some sort of signal is being passed to the screen.

I bought a dehumidifier and placed it next to the TV. No success yet. Does anyone know if the TV is salvageable? My guess is the cable connecting the screen to the processors etc is damaged, or perhaps some of the chips are damaged. Or maybe the LCD panel itself is compromised. Is there a particular part I should try and replace?

Thanks in advance!
