    I just got my OSSC in the mail. Out of the box it worked great. It took me a second to figure out how to change the inputs and everything, but once I figured it out and I had no problems playing all of my OG Xbox games at 480p and 480i. When I first started it up, very occasionally, the video would cut out. I played for about an hour and the problem just went away. I wasn’t that concerned.

    I had just been testing on my entertainment center. I left for a while, then came back and tore everything down and reassembled it all again where I intended it to go permanently. I used the same cables, the same power outlets, everything pretty much identical. I turned on my Xbox and the OSSC, set it to AV2 using video passthrough, and put in my copy of Halo 2. As soon as the game started to load the picture went out, flashing in briefly every once in a while and showing me the incompatible video mode message. What gives? I had literally been playing the same game just a couple of hours before.

    The video signal seems to be stable if I play in 480i with line doubling mode. I noticed that my Xbox, when playing in 480p, output at 31khz and 59.90hz, which is odd because I thought I remember it running before (when it was working) at just over 60hz. I am thinking that is related to the issue some how, but I don’t know what adjustments I can make to get the signal out any better in progressive mode.

    I flipped through the AV2 settings, messed around with the low pass filter, nothing seemed to help.

    I am also noticing that the 480i signal appears really noisy and has a violet line that scrolls up the screen on dark images. That wasn’t there before either.

    I am using low quality component cables right now as I wait for better ones to come in the mail. They are the same cables I used when testing everything both times though, so I am at a loss as to what I should do. I am beginning to think it might be an issue with my Xbox. I tried several external scalers before getting the OSSC and all of them had this issue, which is why I was so exited when initially everything seemed to be working great. Any help on how to get the most out of my setup would be appreciated.

    Stab in the dark but have you removed the clock capacitor from your Xbox?

    I bought the xbox recently second hand. The clock capacitor has either been removed or burst before I got it, because it doesn’t retain the clock after powering off. It is an early model based on the serial. I suspect either a 1.0 or a 1.1 board but I can’t say for sure.

    Does the clock capacitor have anything to to do with the video output? I could get a new Xbox but I am worried that they will all have the same issue and it will be for not. I am beginning to think I need to pair my OSSC with a decent video processor… which sounds expensive :(.

    The clock capacitor just leaks so it can cause all kinds of damage.

    I think you need to open her up and check for bad capacitors for a start.
