Ps3 dont have no sound at all. what to do?

It sounds like it will need a professional repair. there is a good place in nj that can repair PS3 fast and save all the data. the place is called www.videogame911.com.

Yes this is the red light problem you need to use a good guide to fix it or send it in for repair.

It is caused by overheating internally.

First check to see if the ps3 will play that kind of dvd. some are old formats. Update your ps3 if that doesn't work call sony they might have other people with the same prob.

This is an internal electronic problem, you will have to take it to a reputable service technician. Hope this helps you.

same here..... like..... iwas using them for while by connectin em 2 my projector.. i gues.. i jus kept em aside for a few days.. whn i tried 2 use em again... it jus BLANK.... sum1 plz... totally in need of help

when it happens, give it some time, like 5-10 min. the ps3 is most likely accessing the hard drive, and if it is, shutting down in the middle of it could currupt your hdd. if it doesnt work, even after 10 min, call sony tech support, but if it works fine afterwords, i dont see why it would be neccessary. unless it gets worse, i think you should just turn it on, turn it off after a few min, then back on, and then play.

jus keep checking the cables in the back of the tv and if they are in correct it could jus be the video cable is being dodgy lol

Make sure you have the latest firmware update for your PS3.

Although there is several possibilities, check the lens, its inside the tray, it may be dirty.
