Power Cable ¶
Verify that the power cable is plugged in properly and not loose. Also, verify that your source of power (the outlet) functions correctly.
Yellow Light of Death ¶
The indicator light on the PlayStation 3 starts green, switches to yellow, and then quickly switches to red, and blinks indefinitely.
The PlayStation 3 will display this error for two different reasons. To determine what is causing the error on your console, turn the console on, and listen closely for the fan. If the fan powers on briefly, and then switches off, you have an issue with the motherboard. If the fan does not power on at all, then you likely have an issue with the power supply.
Motherboard ¶
The most common cause of the YLOD error and the PlayStation 3 failing to boot is a hardware malfunction on the motherboard. The error is caused by the failure of the solder joints between the CPU and GPU and the motherboard. This error can be fixed by re-soldering the chips to the motherboard, and, while not a 100% guaranteed fix, it is the best option for repairing the YLOD. iFixit offers both kits and guides to facilitate this fix.
Power Supply ¶
One cause of the PlayStation 3 not booting is a faulty power supply. A much smaller percentage of PS3 consoles will display the yellow light as a result of a faulty power supply. If the power supply is faulty, then it will need to be replaced.
EditPS3 Doesn’t Read Optical Media ¶
There are two models of Blu-ray drives for the fat models of PlayStation 3, each with parts specific to their own model. The easiest way to tell which kind of drive is in your PlayStation 3 is to take the drive out and look at it. If the drive has an exposed control board on the bottom of the Blu-ray drive, the Blu-ray drive’s model number is KEM-400. If there is no exposed control board, then the Blu-ray drive’s model number is KEM-410.
If your PlayStation 3 is not reading discs, or is reading discs inconsistently, then follow this flow chart to fully diagnose the problems with your Blu-Ray Drive.
Step 1. Insert a disk into the PlayStation 3 Blu-ray Drive
* Q1. Does the PlayStation accept the disk?
o Yes – Go to “Step 2″
o No – Go to “Q2″
* Q2. Is the Blu-Ray Drive Blocked?-There is a physical barrier preventing your PS3 from drawing in disks
o Yes – Go to “SOLUTION: Gear Alignment Reset”
o No – Go to “Q3″
* Q3. Does the disk eventually get drawn into the console? – You push the disk in ~3/4 of the the way, and the mechanism draws the disk into the console
o Yes – Go to “SOLUTION: Broken sensor board.”
o No – Go to “SOLUTION: Faulty Control Board”
Step 2. Clean the Disk – Using a cleaning solution and a microfiber cloth, clean the disc.
* Q4. Does the PlayStation read both Blu-ray disks and DVDs?
o Yes – Go to “SOLUTION: Your done!
o No, it reads one media type, but not the other – Go to “Step 5″
o No – Go to “Step 3″
Step 3. Eject the disk
* Q5. Did the disk come out in the same orientation that it was inserted?
o Yes – Go to “Step 5″
o No – Go to “Step 4″
Step 4. Re-insert the disk into the PlayStation 3
* Q6. Is the loading wheel present on the XMB?
o Yes – Go to “Step 5″
o No – Go to “Faulty Control Board”
Step 5. Clean the Lens
* Q7. Does the PlayStation read both Blu-ray disks and DVDs?
o Yes – Go to “SOLUTION: You’re done!
o No, it reads one media type, but not the other – Go to “SOLUTION: Faulty Lens”
o No – Go to “Step 6″
Step 6. Eject the disk
* Q8. Did the disk come out in the same orientation that it was inserted?
o Yes – Go to “SOLUTION: Faulty Lens”
o No – Go to “Step 7″
Step 7. Re-insert the disk into the PlayStation 3
* Q9. Is the loading wheel present on the XMB?
o Yes – Go to “SOLUTION: Faulty Lens”
o No – Go to “SOLUTION: Faulty Control Board”
Solution: Gear Alignment Reset
Realigning the gears in the blu-ray drive is fairly simple. Depending on the type of Blu-ray drive you have, you will need to either follow this guide or this guide.
Solution: Broken Sensor Board
Only the KEM-400 optical drives have IR sensors for discerning when discs are inserted into the Blu-ray drive. If your IR Sensor is no longer working, you can attempt to replace it, however, it will in no way affect the performance of your Blu-ray drive.
Solution: Faulty Control Board
If you have judged that the Control Board is no longer functioning properly, then you will likely need to send your PlayStation to Sony. The Control Board is paired to the Motherboard and will only work with its original partner board.
Solution: You’re done!
If everything is working great, then you no longer need this troubleshooting guide. Congratulations!
Solution: Faulty Lens
Being a very fragile piece of technology, it is easy for the lens to break. Both types of Blu-ray drives have a specific lens that will only work with that type of drive. Depending on which type of drive you have, follow this guide (KEM-400) or this guide (KEM-410)d to replace the laser
