Recently my father disassembled a Panasonic tv, model TC-55AS530U, to clean it up in the inside but in the process my mom threw away the screws that connect the back panel to the tv so we are unable to put the tv together, os i was wondering if any one knows the size of the screws in order to get replacements, I already tried to contact panasonic support but I don't get an answer and I've been searching for an answer but I can't find one so I was hoping someone here knew size of the screws.
