PS14 Fuse blowing
What would cause this ps14 fuse to blow. I was trying to chip a friends V8 with green dot. It kept blowing the ps14 fuse. So I took the chip out, replaced fuse again. It did not blow after the chip was removed.
Syptoms were: eject did not work, spindle would not spin, no flash from laser.(open-face laser). The entire drive was dead.
After replacing fuse the first time, when powered on the laser would move in toward spindle then would try to keep going until the fuse blew. It would not bounce back after hitting switch. It would blow within 3 seconds.
I took the fuse from a v7 board for a replacement but the the numbers were different on the fuse. v8=S3 / v7=50. The v7 had no fuse to match the S3. What are the value differences between these two fuses?
I took the chip out and it plays normally.
Is there an alternate 3.3v point that I should use for v8?
Mod-chip.com is showing a different contact point for Y also, should I be using that one?
Thanks in advance
Is there an alternate point for 3.3v on a V8?
How about a V7, since they are basically the same board???
Yes there is a alt. 3.3v but it's under where your chip is. The one you are using is the better one. Don't run your wires along the edge of the board like you have. The metal shield that goes on has little spikes that earth it to the motherboard along this edge. These could cause the wires on your chip to short out causing your blown fuses. Change the position of the chip to something like this (thanks to retro):http://www.psx-scene.com/forums/atta...3&d=1144384650
Thank you for the reply.
Yes I did bend the tabs up on the shielding before reasembly. I also used double sided tape to hold the chip down. It is the thin tape used for window plastic in winter. No thicker than regular scotch tape
If you look closely at the pic you will see a piece of it under the wires on the bios. This also gave me extra space between the chip and the shielding. Nothing was touching anywhere, I could clearly see thru all points. The tape was very strong for holding the chip, but the wire has some kind of coating on it and it did not like to stick to the tape. (30 gauge solid from ratshack)
Could it have been possibly from running 30g solid wire for power to the chip?
