Blown ps3 mosfet

Hi,
I have a ps3 (cecha01 model) which is out of warranty and the warranty sticker has also been voided. The blu-ray drive will not work do to the mosfet with the number 4943b being blown out. All I have been able to find out about this mosfet is that it is a Dual P-Channel 20-V (D-S) MOSFET. I am trying to find a replacement for this but I can not retain the specifics of this item. I am wondering if it is a “over voltage protection“, or just the “power supplies“ mosfet. I have gathered (I think) that the voltage is from 5v to 12v. I would be grateful for what ever info you have on this mosfet.

Thank you for you time.

Having Blu ray issues, not sure if the blu ray games work (don't think we have any) but regular games and digital movies work just fine just not blu ray. We bought a extended warrenty with it, but


Sounds like the Blue Laser may have gone bad. Try swapping out the internal blu ray drive with another one. You will have to take it apart and of course that would void the warranty unless you can make it look like the sticker on the bottom wasn't tampered with. On second thought if it's still under warranty just send it in and get your money's worth! ; )

My ps3 160gb will need assistance how can i open it???


A PS3 can be opened rather easily, but if your PS3 is newer, or still has a warranty on it, I wouldn't open the case. If you're unsure of whether you still have a warranty on it, you can call 1-800-345-7669 and they will give you instructions. If you open your case, you WILL void the warranty. That being said, here goes:

1. Locate the side of the PS3 with the HDD symbol on it(The left side of the PS3). Above the HDD symbol, there is a sticker that covers a plastic cover. Removing this sticker will void any warranty still on the PS3.
2. Peel off the sticker and gently pry the plastic cover out. There is a recessed area with a screw at the bottom, use a small screwdriver to unscrew it.
3. The plastic cover on top of the PS3 is now loose, and you can slide the plastic cover towards the left side of the PS3(where you just removed the sticker) and lift it off.
4. There are 8 screws holding a second plastic cover down. Unscrew them with a Phillips head screwdriver, and set them aside. Lift the cover straight off, and set aside. You have now opened your PS3, and have access to the Blu-Ray player and other internals.
Good Luck!

It will play ps2 games **** not ps3 and it is a ps3


Hi jhoover64,

Launch PS3 models and PS3 models with backwards compability have different disk lenses for blu-ray disks and dvd disks. Which means that you can have a faulty blu-ray lense that doesn't work, but as long as your dvd disk lense works you'll be able to play PS2 games and DVD movies.

Sadly the only way to repair a fault disk lense is by getting it to official tech support. You could try ordering the replacement parts and having it repaired by a third party or yourself but this is not recommended since it void the PS3 warranty.

Hope this helped you!

Disc makes funny noises when loading and cant connect to the internet. i bought it at a pawn shop and dont know how to tell if there is anything wrong with it but the warrenty is voided.


Hi and welcome to FixYa

Ok for the internet problems try connecting it directly to your internet modem without the router and also try connecting it with the wireless option of the ps3, if none of those options works, your ps3 network card is pretty much fried. About the disc making funny noise you might want to first if you know nothing about ps3 take it to a repair store after the diagnostic of the funny noises the next symptom you are going to get is problems reading bluray discs and after that you will probably have to replace the WHOLE DRIVE piece or if you are lucky just the PS3 lens. here are links for more info about prices:

PS3 Whole Drive:

remember after buying any of those check your PS3 Model.

Sincerely,

WHY WONT MY PS3 READ A DISC IT MAKES A WEIRD SOUND WEN I INSERT I TRIED THE RESET THING AND DID IT WORK NO ANY HELP


This is because of an internal gear fault within your PS3. It is possible that someone has taken the PS3 apart before and not put the drive ack properly or there is a possibility that one of the gears inside has broken. You could have a look yourself by following a guide on youtube, just google PS3 blu ray videos. At the very worst you would have to buy a new mechanism for your PS3 blu ray.

This is not actually that hard as all you would need to do is buy a faulty blu ray drive (one where the laser is faulty) and swap over your working laser into it. This would cure your problem. The only thing you have to be careful of is that you get the same model blu ray player as there are several types. To identify the right one you need your model number of your PS3, it is on a white sticker on the back and starts CECH--.

This will be your cheapest option for repairing it unless it is under warranty, Sony have a 1 year warranty with new consoles and will replace it free of charge if it is still in warranty. If it is out of warranty Sony will want around £150 to fix it.

I hope this information helps and thank you for using FixYa

Our PS3 60gb, with 4 USB ports is having problems reading the new PS3 games. The old PS2 games still play. When it comes to games like Rachet and Clank or any other new game, it will start then freeze. I...


Hi there, it definitely sounds like the blu ray player. They are relatively simple to fit yourself as long as your warranty has expired. If it is still under warranty just phone Sony and they will replace it.

If you warranty has expired then you can buy a working blu ray drive on ebay for around £60. There is a circuit board that is attached to the blu ray drive, it is extremely important that you keep this as it is paired to your motherboard. Your PS3 will only work with that blu ray circuit board, no others.

To actually replace the drive is pretty easy. On the left hand side of your console there is a warranty sticker covering a little rubber bung. If your system is out of warranty peel back the sticker a little so you can remove the rubber bung. Under this rubber bung there is a small torx head screw, I think a T8 torx but a small flat blade screwdriver will take it out.

After you have removed this screw the whole top of the PS3 slides to the left and comes off. Underneath the PS3 top cover there is another plastic cover with screws all around it. As you are looking from the front of the console there is a marking on the plastic cover that points to one screw that says "S", this is a shorter screw and only goes back in that place. Remove all the screws. Just to the left of the short screw there is a small recess in the plastic casing where you have to push a little black clip back gently while lifting the cover from the back of the PS3. It should all lift forward and come off.

On the right hand side of the PS3 you will now see your blu ray drive. It lifts up but be careful, there is a ribbon cable and power cable attached to it. The ribbon cable is hidden underneath. You have to carefully lift the long black strip that is on the clips where the cable is held. This will release pressure on the ribbon cable and allow you to remove it. You will see the blu ray logic board attached to the back of the drive. Remove this from the drive taking care with a very small connector with a black and red wire, this is the optical sensor wires, remove with care!! Nowafter you have done that you are ready to replace your blu ray :)

Hope this helps and thank you for using FixYa

A month ago i replaced my blu ray lense myself using a tutorial si ot voids warranty of the part and now my ps3 will only read some blu ray discs no problems with games or dvd any ideas?


you may have installed a different blu ray laser into the consel then the model that was manufactured.... sony and microsoft are contently updating there system and changing small things in the hardware so it is always a good thing to run your model number with the parts that are installed to insure you have replaced it with the proper part

When I put a game in it displays disc error , system rebooted


Depending on how old your PS3 is and what model and manufacturer it could have a dead Blu-ray drive. It was a pretty common error in some PS3's. You could attempt self repair (there are loads of guides on the web) but I don't recommened that unless you're absolutely sure you can do it (it will void your warranty). Call Sony customer support and see how much a repair will cost.

PS3 Blu Ray Drive won't eject


open that **** up,have similar problem,mine was caused because of a sticker on a dvd, couldnt find my warranty,and force eject wouldnt work,i was afraid to open the bluray drive completely,just to the point where i could manually eject the disc and found a round sticky mark on the disc,the sticker is probably still in there,but keeping the ps3 horizontally seems to help,your problem however could involve with the thingies in the driver not being propperly alligned
