solder bridges/balls, and power&ground wires

[toohtaah]

From Charlie's FAQ and Guides page
PS2 backups/imports (CD-R/DVD-R) won't boot or Red Screen Displays
Disk was seen (groove found & focused) but PS2 was unable to identify it as valid disk type (Audio/DVD/PS1/PS2). Note that if the groove had not been found, the Browser would have displayed No Data.

If it¡¦s all backups that won¡¦t boot, first suspect is B C, then try cleaning the laser lens with a cleaning CD. If it¡¦s just DVD-Rs that won¡¦t boot, suspect wires E, R, W or the DVD laser diode (which may need recalibration). Laser Azimuth might also need adjusting.

Then suspect a loose wire, solder bridges or solder balls. If you can¡¦t see bridges/balls, then it¡¦s the hard way. If the BIOS wires are attached, detach them from the BIOS & clean up. Boot a backup using AR2/GS2. If it works, A-I are OK; the BIOS was the problem. (You can try this with the BIOS wires still attached but if it doesn¡¦t work, you¡¦ll have to take the BIOS wires off).

When you can boot backups (including DVD-R) with AR2/GS2, carefully re-attach the BIOS wires, MNOP QTUV RW. Note that R and/or W may be located off the BIOS chip on certain PS2 models. Then try direct booting of backups and/or imports.

I'm not sure if I misunderstand something.

If there are solder bridges or balls, can we still boot the original disks?

What will happen if the power&ground wires are not thick enough? red screen?

Do I have to calibate my laser if I have only pressed DVD and Cd backups?

The reason I'm asking these questions because I'm installing Bluechip and I am quite sure that all solder points are not short to the closed points. However, I cannot put the thick wire to the 3.3V point, so I just used a small wire which is about 3 times thicker than the one I use for the other points and about 2 cm long. Therefore, I'm not sure if the wire is thick enough for the 3.3V point.
I also tried booting backups by using GS2. Unfortunately, my ps2 freezed after I inserted the backup disks.

TIA
P.S. sorry for my english ^o^

You'll be alright with 3 times thicker wire for Power/GND.

Solder bridges/balls can cause unpredictable beahviour with originals and certainly prevents backups from running.

Calibrating the laser should not be necessary.

The best way to avoid solder brides and solder balls is to use a no-clean flux pen. It distributes the solder evenly on the joints you're soldering...

Not to mention, it also gives it that 'professionally installed' look...

Charlie, Rick ...Thanks so much

I'll try to find the error of my soldering....
