hi fella's sorry to but in but i've got the  ps- 50A456p2d when it came in the fuse on the power supply board was blown, i replace it but blew again and tripped the mains, so i disconnected all the boards apart from the logic board which i forgot and blew again but blew some parts on the power supply board, would i be right in saying the screen has gone in this set  thanks for your time 

regards

I'd replace the fuse in the psu & plug just that. If it blows then Mr Clark would be right. Any idea how a screen can blow a mains fuse?
