I have a jtagged zephyr 360. A few nights ago I was playing Splinter Cell Convictions and the graphics became fragmented with green/black bars and blocks. figured it was a game glitch since it only lasted for around 15 seconds then was back to normal. Played for another 2 hours with no problems.
Last night however it happened again. This time it never went away. Powered down the 360 then turned it back on. I noticed the Dash was grainy. Tried Convictions again. Same thing. Tried Earth Worm Jim, didn't notice anything. Then I tried Mass Effect, same effect as convictions. Power cycled the 360 a few times. Nothing worked. On my last cycle I got a 1 flashing red light E74 error then that's all it would give me for a few more tries. That's when I gave up and decided to find something better to do.
This afternoon I powered it back on and the dash loads with the grainy effect and Convictions still has the fragments. That's when I snapped these shots. I need some help on what I should do next to resolve this issue.
