Adjusting the lens height using the gear

I have a scph-50004 ps2 but the problem is i have 2 gears to adjust (small one) now do i have to make them exactly of same angle or should the lens be a little slanted? i Have adjusted both of them to have the same angle but is that bad? I am not getting the best results on all games. Thank you in advance

Re: adjusting the lens height using the gear

First do what i did. get a dvd movie,a ps one game,a cd based ps2 game (timesplitters,rune,dynasty warriors 2,half life)a dvd based ps2 game, and a scratched ps2 game. first adjust the azimuth(the torx screw to the left of the laser} make sure you use a cue tip and 91% alcohol on the lens and under the lens(you have to remove the black cover off the laser). I just got a broken ps2 for 5 bucks and that made it work perfectly.make the azimuth adjustments in 1/8 turns. try all games and especially the dvd movie carefully pull the white plastic wheel out of the top cover for the dvd drive. and pop that on the disk while its in the drive. turn it on and note what happens. if a disk is in the drive before it's powered on you should never see the browser it should just boot.If not you have problems. once all disks are booting good get a problem disk (I used a scratched tony hawk 3) and if the audio skips or freezes adjust the white cog wheel counterclockwise in 5 click intervals until it works perfect. if you are lucky it will work like new if not you might have a laser voltage problem and to fix that you need a variable scope ososcillator ( i know i missplelled it) under the laser is 2 pots to adjust the voltage for the cd laser and the dvd laser. the left is the cd one if its facing you. you can find the proper waveform pattern online in various places.i would just buy a Used ps2 because there preety chaep and definetly cheaper than the stuff needed to adjust the voltage correctly.IF YOU TRY TO ADJUST THE LASER YOU MAY BURN IT OUT.I did on my first one but since my friend was using it as a window stop and i got it for free i donn't care.So hopefully it works out for you guys. if i were you just buy a SEGA DREAMCAST it has none of these problems and is cheap as hell..............................................

Ps2 freezing games

I was experiencing the same problem on my ps2 slim scph-90004. When I put a game in my ps2 it loads but after some time it just freezes at the same spot.I went to many shops but they dont recognize my problem.Then i open my ps2 slim (Warning:Opening of ps2 my void your warranty) and saw the lens which was not adjusted. SO,if you are experiencing the same problem then use the above method(For slim only).Look at the rod near the lens which has two small clips on it. Open the screws on the clips and take out your ps2 lens.Clean it with a cotton.Set the lens in some different position and load your games .

Getting a disc error when turning on the ps2 with ps2 games, but it works with ps1 games...!

Theres a wheel in the disc drive that controls the elevation of the lens. To mod your ps2 to read burnt ps2 games ONE would alter the height of the lens by adjusting the wheel ever so slightly. There are online tutorials in the precise adjustments for different disks. (one height reads only ps1 games, another height reads ps1 and ps2 games, and one more height reads ps1/ps2 and burnt ps1/ps2 games) Your best bet would probably be to just purchase another ps2 used, but if you want to do it yourself, you can.

PS2 Modded Trouble Reading DVDr's

Your DVD potentiometer pot on the back of the PS2 laser lens needs to be readjusted. Some people will try to tell you it's out of alignment but if that was the case it would not read CD's. Some people will try to tell you the laser lens is bad. If that was the case it would not read CD's. On the back of the laser lens are two potentiometer pots. In english? Two lil screws that are turnable. One controls the power of the DVD laser one controls the power of the CD laser.

That link will give you pretty lil pictures of what i'm talking about :)

In a nut shell the story goes like this folks. If your PS2 won't read certain game DVD's that are of a certain color or if it all of a sudden mysteriously fails to read games it once read but will play cd's just fine, the voltage of the laser for DVD's is not set correctly. (this does needs manual tweeking from time to time if you take your ps2 and move it around alot or if you take it over to friends houses etc etc. Basicly alot of movment in general can take this out of alignment. Even keeping the PS2 on it's side could theoreticly (just my opinion) based on gravitational pull, unbalance the potentiometer.


Step 1 identify your PS2 version:

Version 1 - SCPH-30001, 10 screws on bottom of case, serial no. starts with "U1"
Version 2 - SCPH-30001, 10 screws on bottom of case, serial no. starts with "U0"
Version 3 - SCPH-30001, 10 screws on bottom of case, serial no. starts with "U2"
Version 4 - SCPH-30000, 30001, 35001, 30002, 35002, 30003, 35003, 30004, or 35004, 8 screws on bottom of case

NOTE: Version 4 has 2 varieties of motherboard: Gap/No Gap, the difference between v4 "Gap" and v4 "No Gap" is the "Gap" is there's a spot in the center of bios chip where each side lacks solder points.

Version 5 - SCPH-30000R, 30001R, 30002R, 30003R, 30004R, or 30006R. Also, some SCPH-30000, 30001, 30002, 30003, and 30004 models have a V5/V6

NOTE: Version 5 & 6 - the difference between these two versions is one of the connectors in the corner.

Version 7 - SCPH-39000, 39001, 39002, 39003, 39004, 39008 or 37000
Version 8 - Only in Japanese consoles. SCPH-39000, or, SCPH-39006 (GH-022 BIOS 090)
Version 9 - if you have SCPH-50000, 50001, 50002, 50003, 50004, 50006, or 50007 you have a v9 or v10 board.
Version 10 - SCPH-5000x, with date code "3D" to the right and below the serial number on the back of the console. (GH-026 board)

NOTE: To know if its a v9/v10 start up PS2 with no game in it ,press triangle and check dvd driver version dvd ver 3.00 = v9 & dvd ver 3.02 = v10.

If your model # is SCPH-50000, 50001, 50002, 50003 or 50004 AND if you can find a small ''a'' under the SCPH number or have DATECODE "3C" you have a V9 PS2 main board. (GH-026 board).

If your model # is SCPH-50000, 50001, 50002, 50003 or 50004 AND if you can find DATE CODE "3D" as shown below, you have a V10 PS2 main board. (GH-026 board).

Version 12 - The new slimline PS2 consoles are referred to as PSTwo here, but elsewhere they are also known as "v12" units... their numbers are SCPH-70011/SCPH-70012, and also SCPH-70004 CB (Belgium).

Step 2 use either google or the link above. If you're using google your keyword search will be something like "ps2 v12 laser lens adjustment" *replace v12 with your ps2 model.

In either case navigate to the site and follow instructions to set the pots back to their factory default settings.

SCPH - 50004 Pal PS2 colour and reading problem

You need to buy those games which says PAL on it...Usually they have those PAL indications on the top right corner of the CASE of the DVD...of course you won't be able to play those NTSC's just a compatibility issue, i think...cause your PS2 is a PAL model...
