PS2 SCPH 39001 opening the drawer by itself and does not stay closed when trying to close it.

[_XBrD4shDOE_808_]

hello, I recently fixed a SCPH 3900 I had here and I'm using it with OPl, but I want to fix his drive.

the problem is the following, it opens the normal drawer, I press the button to close it, it closes completely but even when inside the console it continues to make noise as if the motor kept pulling the drawer, and then it opens again by itself.
it was complex to understand, but I will leave two links with videos on youtube of what is happening.
I appreciate any help.

I had that same thing happen with a 39001R years ago. I'm not sure I remember what fixed it, but I know it works perfectly now. It's quiet and smooth. I do know I disassembled, cleaned, and greased all the gears. There's a certain way you need to reinstall the tray for it to work properly, but I think that's one of those things Sony changed on all their revisions, so I don't know how much help you'll get unless someone has experience with the exact model.

Have you disassembled enough to watch how it works? When the tray is not physically present it doesn't stop the gears and they just keep spinning for a while. There could be physical damage on the tray or it's misaligned so it doesn't mechanically tell the gear that it's closed.

I watched the videos after I posted(I'm not the brightest) and it sounds like the worm gear that moves the laser back and forth, but it did actually move the laser. Doesn't sound like the plastic gears for the tray, but that might just be the recording.

if the tray is closed and a disc is in, will it spin coming out of standby?

Have you taken the tray out to make sure the plastic gears aren't missing teeth, or not seated properly? Or check the belt?

@Hawk8789
the belt, in this case the rubber belt is good, stretched, without gaps, the tray and the gears are also not broken and are working normally.
the noise of the engine turning is the same as pulling the tray, as if it doesn't recognize it's inside and keeps pushing.
I've already disassembled it in parts, but I've already disassembled DVD players and it works similarly, so yes I have a good idea and I think the problem must be in the motor that pulls.
The switch that tells the system that the tray is working, I've tested it with the multimeter, but I suspect it's not tightening enough to stop the motor from turning.
in a video there is a loud rustling sound, it is the motor that moves the laser back and forth, it is out of grease so it is just like that.

the problem is that it doesn't stay closed, it pulls the tray, enters completely inside the console but in 1 or 2 seconds it opens by itself again, always doing this when trying to close it.
in addition, the laser does not emit the red ray of light that identifies the disc, according to the seller it was damaged but I have a similar unit stored, but I believe it is not working either.

I've been working on my laser and it's driving me nuts because it takes 3-5 minutes to read the disc. It says reading on the tv, but the disc doesn't spin and the laser doesn't come on, then all of a sudden it spins and lights up and reads right away.

But anyway, one time I missed the guide putting the tray back in and it did the same thing, except the tray didn't go in all the way before opening again.

I asked about spinning the disc when it powers on because I'm curious if it works until you hit the eject button. Could it be a dirty contact or bad switch?

Never mind about the switch. I just held mine down and it won't register as multiple presses, I have to release it and press it again. Then I sat there tapping it and it just interrupts it where it is. I don't see how a bad switch could do what yours is doing.

I believe it does not rotate, as it does not emit a beam of red laser light, this afternoon I will open it again and test it.

I have another drive from a 50001 that I can use for parts, but they are not very compatible with each other.

I usually just pull the tray out, hold it, and that seems to have fixed the ones I've tried it on.

A permanent fix for this issue is to modify the motor pulley a little bit so the belt doesn't slip on it anymore. Remove the belt. grab a needle and try to make several lines inside the pulley (where the belt sits) by scratching it. Make the lines radial in both surfaces. Every surface 8 line. I'm not sure if understand what the hell I'm talking about. Let me post pictures when I get to my work room. Clean the belt using alcohol before installing it.

You need to clean some parts additionally. clean the white old grease from gears because they got dried and act like glue. Add a little new plastic grease if you have.
Second part is the trigger switches. There are two of them if I'm not mistaken. Drop some alcohol on them and trigger them by hand several times until they get cleaned.

hello guys, I want to thank everyone who helped me, especially Hawk.

I managed to fix the drawer, I'll try to explain what happened.
the reader was pulled forward and did not emit the laser, in addition to being forced to frern, it was a sensor problem, and the tray did not stop because it was a sensor problem, and the central motor did not move I didn't know why the hell.
The three flat cables that connected the drive to the MB were dry and the blue ends fell off, I had to take these blue ends from other cables and force them into the connector with the flat to make pressure. they were tight, but I hadn't noticed that the mid-engine cable hadn't gone all the way in, right where the two sensors were.
I only noticed this problem because I removed all the cables and measured how far they should go inside the connector and I forced it to go in more and it fit, I turned on the device and the tray worked normally, opening and closing, and now the reader does not make any more gear noise .
the tray shakes when opening, I lubricated the gears, the left sidebar and where the drawer passes and stopped, it was perfect.
I'm from Brazil, most of the country is 127V but in some places it's 220V (where I live for example), and I bought it from someone who connected it to 220 instead of 110, toasted the source, I changed it and now it works for less than 1/3 of the average price of the device.
Now I will try to fix the reader, according to him the reader was damaged, by using burned games, but when inserting a music CD it worked normal, so I think I can recover it, the problem is that the unlocking chip burned along with the source, I had to remove it and I don't want to risk damaging the MB just to run parallel games, in the next few days original games arrived that I bought for testing, I'm very happy that it's working.

A short videos of the device working, if I can make the reader work I'll post the result here.
