PS3 Motherboard problem

Hi nunuk,

Saw your post saying: "Check the PWM circuit in the unit those along with drive transistorsoften fail in these supplies due to its compact size (they often cheapout with parts) also check duty cycle when it works."

Was wondering if you could run me by how to check the:

1- PWM circuit
2- drive transistors
3- Duty cycle

and were they are. I actually got 3 PS3s off ebay for quiet cheap and planned to repair by replacing and swapping parts that are faulty from the units to at least get one of the 3 running, however, to my misfortune (and this was confirmed) all the MOBOs are the one having the problems. All the HDDs, Blurays, etc.. are perfectly fine as tested and verified by a working MoBo.

Please help me. If i can just verify what on the mohterboard is faulty, i would be so excited to get my hands into replacing the faulty components.

Thx!

How do i fix my panasonic crt tv model tc-21xy3 no power


The power supply circuit is faulty. Generally you have to be good with electronics to do it by yourself. Unplug the tv before opening and servicing! Check the fuse, check the capacitors and replace inflated ones, check the transistor that gets signal from the PWM IC. Check the power to the PWM. Replace the small capacitor that stabilize the voltage of PWM. Replace the optron. If your PWM is burned out, you have to check the entire powering circuit - diodes, resistors etc. and replace all at once with PWM. Only one faulty element will burn down entire circuit again.

1997 silverado installed used trans n speed senser plug is diferent and now it wont down shift


If you have adifferent plug for the speed sensor then you probaly have the wrong year model transmission.Even though 93 through 97 look similar they do not interchange.Your speed sensor should be on the passenger side of tail housing,That is the 1995 up design.If you have a trans with the speed sensor on the drivers side of tail housing then you have a 93 to 94 design.93 and 94 were non-pwm units with 5 solenoids.95 was a pwm unit with 6 solenoids with low impediance pwm solenoid.96 and up are pwm units with 6 solenoids and high impediance pwm solenoid.Swapping these units can blow computers.It is probaly stuck in third gear because the fuse is blown or because of open vss circuit.You will not be able to make this transmission work.

My ps3 will play dvds and ps2 games but wont play ps3 games or blueray dvds


Hi, the problem you are having is with the bluray part of the dvd drive the only way of getting this sorted will be to replace the whole dvd drive, first check if you have any warranty before you let anyone do any work on it if you have warranty then you should be covered, check on the ps3 site about how much warranty sony offer from new.

if you have no warranty left then you need to find someone who knows how and what to do, their are several different dvd drives for the ps3 so this will need checking before you buy a new dvd drive, then once you have got the right drive its not just a case of taking the old out and putting the new in what you need to do is take the main circuit board off your old drive and swap this with the one on the new drive. the reason you have to do this is when the ps3 was put together the dvd drive and the main circuit board in the ps3 where married, ie these parts were joined together with software now as sony have done this you cant just change the whole dvd drive over as the new one wont be recognised by your ps3 as it will have the firmware of another ps3 serial number so you need to change the circuit board off the bottom of your dvd drive and swap this onto the new dvd drive, than when you fit the drive your ps3 will think its the old drive and it will then be working.

its not easy to do and its difficult just to take the ps3 apart so be warned.

let me know how you get on or if you need further assistance

please rate this solution as i have a whole page of unrated posts, thanks

PS3 stuck on screen saying hard disk corrupted


Hi

Please refer to this link for ways to troubleshoot the hard drive and sometimes if you are lucky you can recover the problem - however if these solutions fail the unit will have to be sent in for repair I am afraid.

Abit eq software


Does it vary? If it changes, it's probably a bug. If it stays static, it could be either. Try installing a different version, ask ABit Support, check the forums, etc.
