LG did have connectivity problems between the Y-sus and Y-drives on some of their models and introduced a modification clip to improve the security of the connectors. Google EAG61050702 for more info.

ok thanks downunder

do you know what boards these clips were designed for as the y-sus and buffers in this tv are seen in pictures attached

downunder:
They're for the 5 white connectors that join the Y-Sus to the buffer boards. Another way to approach this is to disconnect the Main Board from the Power Supply, turn the set on and short out the AUTO GEN pads on the Control Board. The unit will generate test patterns on the screen. If the patterns are clear and free of lines, it means the panel and scan boards are OK, but if the lines present in the patterns and you've replaced the Y boards, it only leaves the panel. Also reseat the flexi between panel and buffer that sits on the same level as the lines on the screen. These can be a bugger and have to fit precisely into their sockets on the buffers.
