Hello,
My Samsung UE40D5000PWXBT, won’t power on , stand by light blink 3 times when pressing power on the remote, someone told me that means the main board is faulty.Is that true?Is there anything else I could check?
If I’m replacing the main board , is it enough to search for it by the tv model , in this case UE40D5000PW ,or does it have to be exact serial number/code as the faulty mother board?
