Chunder, what's your ethernet cable connected to?
I have an awful time with my PS3 thinking an ethernet cable isn't connected. After firmware updates, I have to turn off the PS3 (with the switch in the back) , make sure my wireless bridge is turned on (which it always is), wait a few min, then turn it back on. THEN I get link lights. Otherwise, no. Totally fubar for some reason.
On to my problem -
When I play resistance, after awhile, when I grab a health pickup, the screen goes black. I have to hit pause quick, and then the screen comes back after a second. I've got it hooked up via a joytech switchbox with PS2 component cables to my toshiba 46HM95. Latest firmware edition.
