I recently got this issue that has ruined my limited tech life. My monitor up until i tried to plug an hd mi splitter on it was working well. after plugging the splitter the monitor keeps going to sleep when i try to use the ps3 or the cable box. i have since disconnected the splitter but it makes no difference. i keeps giving me no signal. i tried plugging in my computer and it works perfectly on the hdmi slot...the minute i try the ps3 or the cable box, i get nothing. i have plugged them on the television and they both work. any ideas on what i can do. i have already held down for 60 seconds and still nothing
