    Samsung UN32M4500 has audio but no video

    Hi, I have a Samsung UN32M4500 that turns on, has audio but no video. No Samsung splash screen when turning on, but I can see the backlights (screen is just this dark gray color). The TV only has one board, which I replaced from one I purchased from directtvparts on eBay. But still the problem persists. Is my LCD bad?

    TV turning on with audio and backlight and no video, the tcon is the first suspect. On newer TVs with tcon functions integrated into the panel, there isn't much you can replace. You can check for shorted chip caps on the panel boards and there may be a surface mount fuse by the connector.
