PS2 won't boot after poweroff

[Budreaux]

Ok, I installed the MI on my v7 and all went well.
I plugged her in and the MATRIX slash screen came up.
I loaded a game and and it read Infinity v1.5 underneath the loading screen.
I played the game for a bit to insure all was working well and it did just fine.
I cam home from work the following day and backedup all my games and took the PS2 from one room to another and plugged it in and all seemed well.. MATRIX splasg screen yadda yadda.
Powered off.
Came back 30 minutes later to test the backups and the system wouldn;t boot.. just black screen.
I was a bit miffed and tired.... 10 minutes later, it got the best of me and I disassembled to recheck everythihg and I couldn;t find any issues..
reassembled, plugged it up, power ON and it worked fine.
Today, my day off.. I decided to get it out and check all the backups... same problem again, just black screen.
Will not boot anything.
Am I missing something here.. I can;t even get tot he config screen.
I want to update teh fiirmware to the current, but It won't do diddly.
I'm about to disassemble AGAIN, but I'm confident in my wiring job, but I'm willing to bet it restarts just fine.
Any ideas as to why this may be happening?

possibly a poor solder connection somewhere, most likely on the bios. Are you using flux ?

[Budreaux]

yes, but, I don't like soldering directly to the bios chip.. I use the traces that lead to the pads and along each one is a hole that allows for a 30 guage wire to be inserted.. I use these holes for soldering.. I've looked at this section a number of times.. I'm metered it out several times to insure a tight fit and everything there is solid.
I have it apart now and rechecking again... but I just don;t see anything.
Gonna wrap it back up and hope it starts again, long enough to reflash to the updated firmware.

[Budreaux]

Well....now I'm must irritated.
Put it back together and I get teh same thing.. nothing at all.. just black screen.
I'm confused as to how it was working perfectly one day, then the next it just gives me a black screen.

I'm to the point now to where I'm gonna uninstall the MI chip and start from scratch...... this makes no sense to me at all.

i think your modchip makes some false ground
try to move the modchip a bit and isolate it with some tape

when the metal plate touch the chip the power flows away and sytems turns on with black screen only

Good luck

AAARRRRRGGGGGHHHHH!!!!!!!!

This is making no sense.
Yesterday, I removed the chip...cleaned up the board and chip and reinstalled again to insure I didn;t overlook some small issue.
I claced the chip in close proximity to the bios to eliminate long wiring.
I used hot glue to mount it on the board and I cleared it from laying directly on another chip (to elimimante any heat buildup issue).

I tinned everyjoint and I used flux at every joint.

I metered the entire install "3 TIMES" to make damn sure of it.

Made a solid ground using 22guage wire.

Made a good strong power connection tot he 3.3v point.

Reassemble the console and it booted fine.
So I updated the MI to firmware v1.75.

It was working flawlessly all night. We played several different games for several hours.

Got up this morning, confident that the console is solid now and DAMNIT.... no bootup.

I get the Red Reset light, Blue Eject light..fan is running, I can hear the Disc tracking.....I hit the reset button and it goes Green and that's where it all ends....it just stays at that point.
No poweroff, just sits as if in standby or waiting for something else.

Here's one question... at first hitting the reset button and it goes Green... it sounds like everything is changing speeds.. speeds up slows down then settles in , but still no booting.. no Matris splash screen.. just a black screen
Is it possible that this console needs a mod to the 3.3v connection to the chip?

matrix Infinity...v1.75 on a version 7 ps

OH.. You guys are gonna just LOVE this one.
I'm almost too embarrassed to tell ya what the problem was this time.
Apparently, the install I did this time was just fine.. it seems that if you DO NOT connect your audio/video connections to your TV, you won;t see or hear anything either. DOOOH!!!

Sorry for the confussion fellas... it;s still going strong.
Lastnight, after the kids went to bed, I turned on the Dishnet receiver and had some weird video issue.. so I disconnected the PS2 video/audio cable.. forgot to hook em back up this morning... I'm embarrassed but relieved at teh same time..

Have a GREAT day fellas.
