First post here so be kind to the newbie.
I have an LG 50PS3000 and when I power up the blue light flashes then a bright screen that looks like a colour negative appears for a couple of second then the TV clicks and powers off. I have been told it may be the power supply board shutting down due to a failing ZSUS board. Can anybody confirm and if so tell me how to identify the location of the offending ZSUS board so that I might get the part number and find a replacement.
Thanks in advance.
