Facing TV Problems? Ask a TV Technician.
Hello, What do you mean- does not hold power on setting- do you mean it shuts itself off?
I don't know what that means "it needs to come on again". Please reply back in complete sentences in detail.
I understand now-this is the Mainboard that causes this. Now, are you able to use the rest of the controls on the TV when it is ON (Input/Device, MENU, volume, etc.)?
Also, are you able to shut it off using the power button on the set?
Okay then you're looking at either the keypad controller having a fault or the mainboard's turn on command- not something to do with the settings. The question is- do you really want to take the set apart and replace parts to fix that?
