Is the light blinking at the front ?
By the way , you were talking to a computer at the beginning so never mind the odd questions , its still learning
O.k then no blink code will point to a defective main board beside those clues about the Ethernet failing and especially if you already replaced the power supply.
This board part number TXN/A1UFUUS can be found at the links below ;
Or this one ; https://www.amazon.com/Panasonic-A1UFUUS-Input-Signal-TNPH1045UD/dp/B019AFCYH2
