I bought it from a appliance center and I am not sure if the warranty covers LCD. I really dont know what to do. I bought this brand because its SHARP but its just like local brands that can easily get damage. Can anyone help me out please!!!
If no apparent physical or water damage warranty is a good option
I believe mfr warranty is one year maybe check sharp website . Do you have extended warranty also?Manufacturer warranty will cover panel but not physical or water damage
Moisture can permanently damage panel bonded tab connections. Bonded Panel Connection Tabs are inside at one or more edges of screen.
so you do not want any water or liquid to drip or flow behind screen edges nada.
Never spray anything on the panel use dry microfiber or 100%cotton baby diaper or undershirt . USE only slightly moistened microfibre or soft cloth to clean screen . Windex can kill them in a heartbeat sometimes symptoms do not show up right away panel connector corrosion can take some time , also they can malfunction on their own without help . Distilled water or a few drops very mild dish soap diluted in water used to dampen cloth is best Or whatever your owners manual recommends .
Also anti glare coatings usually do not like too many liquids
. Lots of well intentioned housekeepers ruin panels with windex .

If You find a bad board get the number off of the board itself then Google that # something should come up also Ebay has lots of boards

Sets within a given model number* may use different boards so best to use actual board number when ordering replacements
Yours *may* be be T-Con board .also gently wiggle board connectors maybe check panel connectors
