Newb in trouble

[ExMen]

Hey all,
I just modded with the Xecuter3, flashed with X3 bios, no problems with reboot, came up as expected. Now the fun, I installed a 250Gb WD HD. Booted to Slayers 2.6, did a new install. And being a newb (dumbass) I didn't pay close enough attention to the screen (I was flying since everything worked so well!) and flipped dip switch 4 to ON when I ran Slayers.

Now when I start the box, I get a scrolling screen with no color, can't read since it is scrolling so fast.

I put the original HD back in, thinking I had F$#@ed up the Slayer install, but still get the same.

How can I boot to my good BIOS CDRW and re-flash my chip?

Thanks in advance,
ExMen (aka dumbass [for now anyhow :wink: ])

Jovy 7500 reflow station.

Hi just intersted if any members on here have had any dealings with the jovy system or are running one at the moment or thinking of buying one in the future. I have had one a week and getting mixed results..

Re: Jovy 7500 reflow station.

i don't have a jovy system, but it took my several unit before i learned correct reflowing techniques...... it's not just straight forward like the manuals say.....

check your secondary error code before you start your repair. if it changes to 0020 or 0022 then your most likely done and won't be able to repair it. if it is 0020 or 0022 before you start the repair and it's never been fixed before then your still ok and should be able to fix it.

1. make sure your pre-heating the board to 150C degrees
2. let it pre-heat at 150C for 4-5 minutes.
3. make sure you use no-clean solder flux all around the chip you are reflowing
4. I find that any temp above 225C degrees (with the IR lamp) will destroy the chips.
5. when your ir turns on you want the IR temp to ramp up to 225C degrees but it needs to take 25-30 seconds to do this to keep the solder
from popping and shorting to other connections. thats 2.5C degrees every second.
6. as soon as you hit 225c turn the ir lamp off.

my repair success rate is almost 100% on units that have never been opened, units that have had any type x-clamp mod or penny tricks or towel tricks have a 50% chance of repair, it will either fix it or turn the secondary error code to 0020.....

you don't want to use the rework station to reflow the ram chips it will kill them every time, for them you need to use hot air. but on most systems if you only reflow the gpu it will fix it 99% of the time no matter what the error is. even the ethernet port error e73. i've never had to reflow a hanna/anna chip and reflowed the southbridge chip 1 time for an eithernet port error.

good luck.

Re: Jovy 7500 reflow station.

Thanks for the reply Mighty. Sorry for the delay in mine but been buried in xboxes and that reflow station. I seem to have the balance now hopefully. Fixed about 7 360's and 2 ps3's so fingers crossed so far so good. Just one now that didn't fix and has secondary code 0201. I'll keep trying. But thankyou so much for the advice matey much appreciated.

Re: Jovy 7500 reflow station.

Hi guys.

I'm in New Zealand and seriously considering getting one of these machines.
Just a few questions if you have time to answer please.........

What was included in your package?
PCB Supports, Reballing Jigs, Balls, anything, nothing?
Did it take long to sort out?
When reflowing a 360 (example), how long would you say it takes from start to finish?

Thanks guys, much appreciated

Re: Jovy 7500 reflow station.

You get absolutely nothing included. tell a lie you get the xy table that's no good for anything and have to make jigs to support the 360 and ps3 motherboards so that it can be bolted/clamped down to prevent warping as the temperature you need to reflow 220 will just bend the board to sh*t if not supported. There's not much in the way of support from the manufacturers either. Oh and make sure when you make a template for the 360 to reflow you use an old motherboard and not a customers..All that being said don't let me put you off I own one, but feel I need to be honest so you don't rush in with your eyes closed. It is a great beast when you get your head around it. slowly slowly catch a monkey..If you want any advice or support just pm me.. :wink:

Re: Jovy 7500 reflow station.

Oh forgot this part from when the board is on with all paste removed the process takes about4-5 mins from cool. When done I let it cool naturally for 40 mins which really slows progress down. I set a timer for 40 mins then rebuild. There are fans on it that can cool it down in a matter of a few mins, but a friend of mine who's a bit of an expert in the art of welding reckons blasting it with cold air is going to create more problems than it may cure. Cooling should be a slow natural process as in warm it down as opposed to cool it down as it may cause fractures in the solder which is one of the reasons xbox's fail in the first place..This is just my experience with hte machine and so far so good..

Re: Jovy 7500 reflow station.

Hey, I really appreciate your feedback. You haven't put me off at all but funny about the customers boards for testing and setting up, hehe. I hadn't planned on using the fans to cool down as you said, natural cool down process would be better and less likely to cause any solder faults. Good idea on the PCB supports too. I'll keep that in mind when the machine arrives. Thanks again!

Re: Jovy 7500 reflow station.

So have you ordered? or are you going to order??

Re: Jovy 7500 reflow station.

watch this vid..I wouldn't go with this guys settings on their template but he's used his head and made a jig...

Re: Jovy 7500 reflow station.

Yeah I have ordered already. Just waiting on it to arrive. I got a friend who has a different BGA machine and he got his own jig made, so I might ask him to get one made for me. I've seen that vid a few times already but think I'll experiment myself on a few wasted boards I have here so I can satisfy myself with my own settings.

Re: Jovy 7500 reflow station.

Hey I just got in the market for this machine and want to be sure that this comes with everything needed
http://cgi.ebay.com/JOVY-7500-BGA-Xbox-Infraroja-Rework-IRDA-Reballing-80mm_W0QQitemZ390160525561QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item5ad76128f9
if not what else do i need to get started? (other than the 110-220 converter)

I will be pming you once i receive the machine for some basic help if that is okay.

thanks for your help!

Re: Jovy 7500 reflow station.

You should get your own jigs made for the boards you're going to work with. Especially if it's 360 and/or PS3 boards as they tend to flex with the heat.
Also, check the laser and UH are aligned properly.
I played with mine on a wasted 360 board and found that the laser wasn't calibrated properly with the UH and therefore the UH was heating in the wrong place and not where the laser was pointing.
I adjusted the laser pointer and now everything is perfect.

I've been playing around with mine a bit manually and have discovered some good setttings for doing different jobs

Re: Jovy 7500 reflow station.

I'll have to look into that.

My money should be transferred tomorow so I can order it asap!

Re: Jovy 7500 reflow station.

Ok, I'm no expert at this but I do stick with it and never give up. I've read some horror stories regarding this machine and it kinda bummed me out a little, but I persevered.
Though I've only had my machine for 2 weeks, I used a wasted board from both PS3 and XBox 360 to practise with. Not using the supplied profiles, I created my own and today, I was successful in repairing both PS3 YLOD, and XBox 360 E74 errors.
As you can imagine, my confidence in the machine greatly increased.

I'm happy

Re: Jovy 7500 reflow station.

yea I too have heard bad stories about the machine, but I figure the people who said this stuff arent very persistent and give up easy.

I plan on making money with this machine so I will work with it until I master it!

Glad to hear that you got your machine workin

mine should come in today so im excited.

Re: Jovy 7500 reflow station.

hello I too am in NZ and have just got this unit. So far I been testing it out on a couple of xbox360 and ps3, all are dead broken boards for testing.

Having some very weird stuff happening. For example it takes ages to get the pcb to 190-200c and then again to 220c which is not hot enough so getting too 240c probably take 30minutes !!!

I do not understand whats the deal with this system, I have set it to level 3 on the thing and that helps a bit. Gotta make a mount for the 360/ps3 as per people say they bend like crazy. I would be interested in anyone has any guides on doing such a thing, will probably need to goto a pro and get something made (somewhere in Hamilton somehow).

Atm I'm a little disappointed because I was under the assumption that this thing could get the boards up to temp fast but the durations im looking at are stupid. Gotta talk to a professional user on the 7500 and figure it out. I have done according to what many people suggest.

Another odd thing is my laser temp probe often detects a much higher temperature (up to 30c sometimes) then what the probe does, but only at the higher temps. The jovy probe often stalls on 200-210 jumping around for got knows how long.

Re: Jovy 7500 reflow station.

Hey Prime

I'm in Auckland.
PM me so we can chat about the Jovy and maybe we can work together on mastering it

I've been fixing PS3s with it and got the reballing sorted, but haven't quite got the resetting of the GPU chips for the 360 yet.
