Tips & Tricks

  • Put a sticker under the chip and over the chip once you have finished the install to prevent any short circuit.
  • Use thick and short wires for 5v/3v and GND so the chip always has enough power to operate reliably.
  • Use flux while soldering to achieve a juicy and well connected solder point. Make sure you clean all the flux afterwards - otherwise strange things might happen ;-)
  • After a long break in development we finally managed to succesfully deliver the H2O+ V2. The only problem that has occured to some installers that were new to this chip is not being aware of how to correctly solder 3v and GND points. Even when using thick wires You must use lots of heat when soldering to the GND point on the PS2, so that the solder bonds well with the copper on the mobo. We are running the chip at 100MHz and that requires 250mA of supply current. The old h2o may accept even sloppy gnd solder joints, but not the h2o+. All performance issues with the h2o+ are quickly fixed by putting a drop of solder grease / flux on the gnd points and heating with a 30W+ solder iron for 10seconds until it fully melts and wets the copper gnd plane. Bad solder point: |badgnd.jpg| Notice how the joint is in layers and not bonded to the copper. Good solder point: |goodgnd| Notice how the points on the ps2 and the chip are rich, smooth and shiny. This is achieved by the use of flux and heating with a 30W+ solder iron for a long enough time to heat up both the solder and the surface it is applied on.
  • When you are closing the ps2 make sure that you will not squeeze or screw a wire with the metal shield. Keep wires clear of screw holes and copper pads that get pressed by the casing. Sometimes if you ground one of the B G H I wires the mechacon chip will blow a pin and the ps2 will not be repairable :(
  • Make sure you always clean the RST point and the tracking v12 fix points (little resistors you solder the v12 fix to)
  • The RST point is sensitive to interference. The tracking points are op-amplifier inputs; any leaking current will get amplified and melt the lens coils sooner or later!
  • For improving PAL/US v14-v16 boot rate make sure the H solder point on your modchip is clean of flux - otherwise half of the time the chip will think that you've modded a JAP PS2. This problem can be eliminated either by cleaning the modchip solder points after install (recommended) or by soldering a wire from modchip H point to 5V. Also make sure you scrape well the B G I vias and use thick wires for 5V and GND. By eliminating these two common problems You should have 96% bootrate (1 faliure every 10-20 boots).

Troubleshooting

  • If the cd head moves like crazy
    -reinsert the tracking motor flex cable.
    -clean A pointbr
    -check that no solder balls are lodged between the pins of the chip (DSP) that is near SX point
  • If the cd does not spin
    -reinsert the cd motor cable
    -if any resistor/diode fix was applied, replace the resistors you soldered to and apply the fix accordingly (v12 only)
    -check PS13 fuse (5v chips only)
  • If the cd spins up and down
    -if any resistor/diode fix was applied, replace the resistors you soldered to and apply the fix accordingly (v12 only)
  • If the cd spins up and down on DVD movies
    -resolder S wire and clean the area of flux.
    -if the subzero fix was applied, recheck the fuse solder point and the capacitor on the fix pcb
  • If the laser head does not move
    -if the subzero fix was applied, recheck the wire and the via
    -remove A B G (H) I S wires and test if it helps, then resolder
    -check ps11 fuse
  • If the ps2 does not turn on, but the standby led just flashes green once
    -check ps14 fuse (3v chips only)
  • If there is no video signal
    -check the P O N M Q T U V R W wires
  • If the ps2 starts resetting every 0.5 sec randomly on dvd media
    -clean area on both TR solder points (SubZero2 only)
  • If the ps2 resets after 1h of play or sooner
    -clean the area on both RST points
  • If the ps2 always boots to the language select screen
    - you have shorted 2 or more of the B G H I points to eachother.
  • If there is no picture AND the DVD mechanism does not move
    - you have grounded or cut one of the B G H I tracks.
  • If the sound is distorted and some of the letters in the ps2 menus
    - you have bridged one of the M N O P Q T U V data points to an adjacent address point. If removing the bridge does not help - you have blown an address pin on the DSP (big chip near SX point) - if you can; replace it.

Step-by-Step Install Debugging

Step1
  • SubZero2: solder 5V, GND, RST, P O N M Q T U V R W
  • H2Omod: solder 5V, GND, RST, P O N M Q T U V R W
  • SubZero2: hold reset for 3sec from standby, then tap 1x reset
  • H2Omod: hold reset for 3sec from standby, then tap 1x reset
The ps2 must go to browser by itself.

Step2

  • SubZero2: add A B G (H) I wires
  • H2Omod: add A B G (H) I wires
  • SubZero2: insert ps2 backup and press reset
  • H2Omod: insert ps2 backup and press reset
the game must boot.

if not:

  • -add thicker wires for 5v/3v/gnd
  • -recheck the A B G (H) I wires

Step3

  • SubZero2: add Z wire
  • H2Omod: add Z wire
  • SubZero2: insert ps2 backup and press reset; half way thru the intro movie take out the disc and put it back in
  • H2Omod: insert ps2 backup and press reset; half way thru the intro movie take out the disc and put it back in
the intro movie must continue when you reinsert the disc

if not:

  • -check Z wire

Step4

  • SubZero2: add TR, S wires
  • H2Omod: add SX wire
  • SubZero2: insert ps1 backup and press reset
  • H2Omod: insert ps1 backup and press reset
the backup must boot

if not:

  • -check TR, S wires
