I know how you feel that is exactly what mine was doing before the blu ray just up and died..found out what the problem was that caused mine after I had my cousin who owns his own computer business look at it and mine died from a mix of dust build up and monoxide residue (which came from it being in a home with people who smoked. not me but my family). Now, I have no other option then to buy a whole new console which I plan on doing in december. (Mainly because of other finances)

hi peeps ive found a way off fixing ps3 laser kes-400a's

 

it so easy to fix

 

all it balls down to is bad joints on the blueray laser....

 

first i made a laser tester

 

made with 2 wire's and a 9v battery simple

 

then i i tap the 2wires on back off the blue ray laser and bingo it glowed up blue

i then i resolider the joint and bam works like it just come out off the box

 

if u need help drop me a email @ ****************** and i'llsend picture's etc etc

 

saves u paying out $100 bucks for new one

And I moved out of the other residence and where I live now (with my sister, until I can find my own place), and good thing is that they all smoke Outside, so once I get the new console (hoping to buy the GTA V 500 GB Bundle), I don't have to worry and the monoxide residue situation, only the Dust which I plan on eliminating too once I buy the Canned Air Duster system

I seriously do not recommend anyone doing this, if they care about keeping their laser working.

 


What you are doing here is that you are dumping the full voltage and maximum current capacity of the 9V battery **directly** to the Laser Diode. This is a good way to insta-kill it and you'll be left with a burnt out, dead laser. Or at least seriously shorten it's lifespan.

 

 

Spoiler

Detailed Explanation why this is bad:

 

Before electricity goes to the Laser Diode, electricity goes through something called a Laser Driver first.

 

A laser driver does two things:

 

1. It steps down the voltage to something something reasonable. The voltage varies diode to diode, but this site states that the BD laser operates from 4.5-5.5V. Putting 9V on it will definitely exceed the diode's operating voltage.

 

2. More importantly, a driver limits the amount of current the diode recieves. Laser Diodes and LEDs require current limiting, as they draw as much current as possible from their power sources. This 9V can supply 500mA easy, and pushing 500mA through a diode rated for 35-90mA would quickly, quickly kill it.
