Thank you for explaining. My husband is here and he is an electrician. Went out to truck to get his tester...

It seems power supply board failure, it needs to check BU5V (standby 5V) on PD connector of power board with multimeter while TV power cord is plugged in.

If 5V DC is available then problem would be with main board of TV (main processor board where video/ HDMI inputs are located) and if no 5V DC reading then power board is defective and should be replaced.

Please click following link to view power board image and part number info for this model if you have plan to do it yourself..

Following link will show main board image and part number info that can be used to search/ google to get replacement board price info..

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV.
