v13 - Chip works, then i screw machine together..

**EspeN** · 02-06-2006,07:22 AM

And i get black screen.

It was a MATRIX INFINITY and V13. I modded it, tested it. All OK. Even flashed it. ALL OK!

Then i put on isolation tape like i always do, and screw it together.
Now, when i turn on i see a short flicker then all BLACK.

The dvd laser respond when i put in discs and spin and stuff, but black screen.

I removed the chip, same shit. Black screen.
I checked with multimeter all BIOS points for the 5th time. There is no bridges.

I found myself a v12 fuse diagram and checked continutiy on all fuses. They had that all of them, so no fuse is blown then?

Do anyone have ANY IDEA what to do? or do i have to get customer new machine here?

Hmm. I vacum the board now too.. Shit shit.
I measure volts when its oN, goes volt thru all regular places.

It looks like the laser understand what disc i put in it too.
If i put in PS2 original the disc keep spinning like it would do if a game works.
If i try with backup (i have no chip now) it start spin, then stop like a ps2 would do...

Its just no audio out or video out.
Please help!!

looks like u blew the audio/video out fuse... or blew the chip that controlls it.

looks to me like CXD2947 is bad... try replacing it

**EspeN** · 02-06-2006,01:46 PM

What is CXD2947? Can u point me to it on a diagram?

**EspeN** · 02-06-2006,02:15 PM

found it. Is Fuse 14 the video fuse?
What chip controls the video?

I tried bridge bios point, and then i got no flicker on startup. So i removed the bridge and it flicker again.

I also checked the VOLT from AV OUT cable, its approx 5v.

Dont give up on me guys!! I replaced the unit for customer with my own unit, so bought myself some more time :O

hmm strange i just got the same problem... but the machine still works if i unscrew it so maybe i have placed the chip wrong on the motherboard, so it gets to tight or maybe a short somewhere...
Dosn't your machine work if you unscrew it?

**MaximusDK** · 02-08-2006,07:08 AM

i dont know where you mounted your chip but be carefull.. there a some small taps on the metal plate that connects to ground on the motherboard so you have to bend them up or just cut them off so they dosent touch the chip and make a short.

I removed the chip now, and still dont work. Ive measure all bios points with alternative points, no broken traces. Its very weird.

I found a soldersplash on the AV out points, but i removed it. Might ****ed things up, but no fuses is gone.
