Brand new to site and in reading I guess I have many more problems yet to experience, whoopee. I have a Samsung HLR6167WX/XAA DLP TV. The inputs on the main input board have been failing over time, 1st the HDMI, then the components now only the AV on the side works. I can get input if I jiggle the input cables on the component but only intermittently. I tried Samsung parts. com but they only show the auxiliary board. Anyone know where I can find a main board?
