Just wanted to see if anyone could help out with my experience. I wanted to try PC gaming on my Hitachi 51 RPTV. I have the ATI 9800 all in wonder installed so I plugged in the red component adapter into the video out on the card. When I attempted to plug in the component cables from the TV into the adapter I heard a pop and saw flash come from the back of the TV! I'm sure it's not a shock to some of you the input I was using is fried. I thought the problem might have been that the TV and PC were both powered on when I did this so I thought I'd give it another go with input # 2. Don't worry the TV is under Circuit City warrenty anyways so what the hell. So I turned off the TV and unplugged the PC. Now everything is hooked up and I turned the TV on. Ok...nothing blowing up, Let's try plugging PC power in... wooooow - nevermind! As soon as I plugged the power cable into the back of the PC the lights dimmed and a loud buzzing occured!?! Also when i try to connect the cable (coax tv cable) to the back of the computer (ATI tuner card) it sparks like crazy. Everything is hooked up correctly and everything works fine by itself. It only occurs when I try connecting soemthing to the PC - weather its the receiver, tv, or cable. Now i'm pretty sure it has something to do with the electrical in this old apartment building i live in because i've had the cable (tv) connected to this same machine at my parents house with no problem. Others have suggested it maybe because the tv, receiver, cable have different ground points than the computer does. Does anyone have any ideas on how to fix this? Any suggestions would help.
