bridged dead ps13 dvd no read

**z_thk** · 08-29-2003,06:45 AM

Hi guys!

I have searched this forum for my problem but could not find a solution.

The shop I work for gave me a dead v7 to fix. The problem was that the discs did not spin, which I simply fixed by bridging PS13 which was dead. the area around ps13 and the row of resistors in front to the left of it had a colour which showed that the area had been really hot, darker that the rest of the board. Allso all resistors show 0 ohm.

Everything seemed to work fine for a few hours but all of a sudden dvds could not be read anymore.

I have checked the laser coils and they are ok. Once the ps2 even put itself into standby while trying to read a dvd. And operations like eject seems to go slow..

Does anyone know what should be replaced? I have checked the BA5 chip, and its ok. I dunno how to check the other BA though.

I somehow have the feeling that the whole system recieves too litle power...

Thanks guys..

The fact that the resistors show zero means that some thing must be shorting across them some where - which would explain a little why the station gets hot and why it shuts itself down.

Are you sure you shorted the right place?

Check for dead capacitors as these short when they die - more often than not.

Check for dead diodes also as this may cause the short you are seeing...

apart from that - good luck... you are possibly going to need it

Thanks for your reply ShadowKnyght, searching this forum I can see that this kind of problem often leads folks to become one of "those" people.

However this station is really not my responsibility, since I am only to repair it if I can for this shop keeper that I sometimes help.

I did bridge the right point i.e the ps13 fuse...damn.. if I should have replaced it instead of bridging it, maybe it would have blown and caused me to look for other faults, when it was still time..

I am gonna look for shorts on capacitors and diodes.. I did allready, but since the area is full of vias I will have to check in other places than the imideate fuse area around the regulator IC I guess.

Thanks

never bridge fuses , replace them cause they blow for a reason and by bridging u can kill ur ps2

yeah... skydemon

too bad that I was to lazy to take the bus from the suburbs to the city to buy a fuse..

**ShadowKnyght** · 08-31-2003,02:38 AM

huh

my PC power supply just killed itself last night and I opened it up to find the fuse blown...

ever seen what happens to a 6A fuse on 240V when something is wrong with the PSU??

The replacement fuse I put in exploded in a red glowing flash and bit of glass and metal went every where... I think I will leave it alone and get a new one!

Now if I had just bridges the the fuse holder.... kaboom....
