Got my hands on a LG 42V7 with a blown Y-SUS IPM. Original YPPD-J014C was replaced with a STK795-811A. Has probed the other power components on the Y-SUS board, without finding anything other blown. Va and Vs supplies trimmed exactly to spec. Believe it or not, but the OSD and MENU's work fine, but there are all black "picture" information. If adjusting VsetUP and VsetDN will give a dark / sparkling picture, can barely see the picture from the video source.
But, how on earth could the menu and osd work good then?
Just had the panel service manual from elektrotanya, but I might need some good advice before I dig down in this.
