Re: testing a main board
Put a bit of solder in does both end need to touch at back of control board? Didn't get test patern.

testing a main board
hi all
i have an LG 60pb690v which im trying to diagnose with no luck up to now, i have replaced zsus, ysus and power board. A little more research shows the issue could lie with the main board. I am wandering if anyone can help me how to test this board to figure which component is the issue. The tv has no picture or sound but i get the standby and click. i have attached a picture of the board i want to test,
thanks
sarah...
