My ps3 has a fuzzy screen when playing on it this only happened a few days ago should i tae it back as it is only 4 weeks

First try video reset

when ps3 is in standby mode(red light)
press and hold the power button till you hear a second beep.

standby mode press hold power........"beep"......"beep"..release power button



then try rebuilding the database and the file system in recovery consol

to get to the recovery consol press and hold the power button when ps3 is in standby mode(red light) till you hear a double beep. sometimes the ps3 does a beep then another beep and goes back into standby thsi is fine just release the power and quikly press and hold it again till you get double beep.

like on my 80g system it goes like this

ps3 standby...press hold power.......beep .........beep........stanby again....release and hold power again.......beep .........double beep...release power now you should be in recovery menu.


then take it back as these steps will not void warrenty
