Recently I was given a 72 inch Samsung DLP for free. I make a hobby out of fixing these fat old TV sets and then finding deserving people to turn them over to, usually just for the cost of parts. In this instance the set needed a new bulb. Done. But the audio volume was virtually non existent. Everything worked just fine, but no real volume out of the TV was available. I figured it had something to do with the DVI board (all that stuff on the left side of the TV) versus the center (light engine) or the right side (power supply.) So I hunted around for a replacement and found the same unit out of a 67 inch version. Since it had the same part number I bought it thinking it would solve my problems. After installing it, I'm kinda stumped. Whilst my previous DVI assembly worked well except for no volume, this unit does not. Instead, the TV keeps clicking loudly out of the power supply. Nothing about the TV has changed except for that DVI assembly being swapped out. So why am I getting this loud series of clicks out of the power supply or possibly ballast and no lamp, no screen, no nothing. They were just fine previously. I guess I will reinstall the old DVI assembly and see if the TV returns to its previous state. In which case I'll declare the replacement DVI assembly DOA and try to return it. But I wish I knew why this solution didn't work. Any thoughts from any of you who know so much more about these sets than I do????
