PS2 DISC READ ERROR!!!!

Hey guys!

So I'm having this very frustrating and annoying problem with a ps2. So I saw this on ebay for like $20 and the seller listed as working just that there was a disc read error. For $20, I was like "Shouldn't be to hard of a problem". I received it today and it was exactly as he listed. The ps2 turned on just fine, but whenever i put in a retail ps2 disc in it, it would boot up and take a very long time at menu and not boot to cd. I decided to disassemble the ps2 and swap the lens with my other ps2 (Same model, laser worked perfectly fine) hoping that it would fix it. I also noticed that there was a magic 4 modchip installed (from what I saw, it was very well installed modchip). I reassembled the ps2 and again same error (Disc read error). I disassembled it again and unsoldered the modchip thinking it was the modchip causing the problem and again there was a problem. I did a continuity check on all the cables connecting the dvd drive to the mobo and there seemed to be continuity. Now I'm truly stuck and not sure what I can do to fix this! I'm out of ideas! I'm hoping someone could please help me!

Thanks!

I'm not sure if this is the right section I should have posted.

 

I've seen common broken chips could be: LA6508, BA5815 (for FATs) Do not know how to check if they are functional.

 

THANKS FOR THE REPLY MAN! So the board having the problem is a GH-013 V4 and i have a scrap V7 mobo. Anyway i can replace the chip you think is dead? From scrAp v7 mobo onto v4 mobo?

Just want to mention, i have the skill to replace the chip. Whats the chip that could be possibly damaged on the V4 that needs replacement?

UPDATE!!
So i went about using my v7 chip on v4 and i replaced it though i still get disc read error. Could it have been a faulty install? Should i buy a new chip? Should i check my install again?

 

Are the lasers exactly the same? A console that was meant to use a Sanyo R-type laser (Sanyo SF-HD7) will never work properly with a Sony KHS laser. Since yours is an old console, you cannot change the laser type with software and hence you must replace the laser with a compatible model.

It's known for consoles of the same series to have slightly different loadouts. My SCPH-39006 has a Sanyo SF-HD7, while the SCPH-39001 that I once had was fitted with a Sony KHS-400C.

 

Thanks for the reply!
So the lasers I swapped are NOT exactly the same. The one originally in the console was a KHS-400B and I went about replacing it with a KHS-400C from my v7 console. Then when I read the earlier reply, I desoldered the chip from my V7 board and replaced the V4 chip with it and I made sure I correctly soldered everything however it still says disc read error. The chip in my V4 console that I took out was a BA5815FM 140 T29 and the one I replaced it with was exactly the same except it had something else other than 140 T29. Should I buy a 400B laser and a Ba5815fm 140 t29 chip to make sure everything replaced is exactly as the original? Ideas?

 

A KHS-400C should be a compatible drop-in for the KHS-400B.

 

Did you try to put a CD (not DVD)?

 

I find the PS2 Disc Read error really annoying and think it was purposely done by sony. As I have a Namco Museum disc and it kept saying disc read error on it. So I decided to try an install with hddloader thinking it wouldn't hurt. And sure enough guess what happend? It actually installed. So I am thinking sony's software is making it purposely say disc read error after the system is a certain age which is just after the warranty expires. At one point they had a class action lawsuit for the disc read error issue and all they did was for those who recently purchased it would be repaired, those who lost functionallity of the system got $25 and a free ps2 game from a specified list not sure what good that would do if they ps2 didn't read discs anymore. Also they would offer a reduced price to get the system repaired. Didn't sound like that good of a deal to me because if you recently purchased the system they would be repairing it for nothing anyways. And $25 for those who have the issue with a expired warranty and a free game with a reduced repairing price? Really you could sell the system on ebay probably for around $30 for parts at that time and either way they were going to charge a person for repairing a out of warranty system. I bet even the newest slims they made not that long ago after the class action lawsuit still have the same issue.

 

WOW! So i tried CD-R with audio and it read that JUST FINE! No problems! Even played a few tracks however when I tried a game , it did not work and gave disc error. Also, i'd like to add that I went on to try the original laser it came with and to my surprise, that read CD's just fine but has a disc error on dvds.

What could possibly be the case now? It can't be a bad laser since this is happening on both lasers (AND i know the KHS-400C is perfectly working). I replaced the chip on the board with one I am sure of working. Like I can't think of anything else.

 

I dont think so. Its just crappy burnt out lasers. Sony is all about saving money where they can.
I just killed the DVD laser part of my debugging station last year while still getting the last bit out of it, but the cd part is working like a charm still after some slight readjustment of the pots. And it got used alot in the last 12 years.

 

So your saying both of my lasers are burnt out?? really? How can this be though? I mean the KHS-400C was pulled from a working console so I know it fact the last is fine.

 

There is no reason to make it on purpose for Sony AT ALL. Consoles priced below manufactured price or close to it. And rather than repairing console many just won't use it anymore. Sony gets money from games which consimers buy for working consoles.

 

So what are my options guys according to whats happening

 

adrianr2z, Does file structure of original game DVD shows up in ULE?

 

ULE?? Whats that? When i go in browser, it just says disc read error.

Oh sorry ULE. I found out what it is. I do not have that program.

 

Anyone have anymore suggestions? This has been the only forum to have helped me out so I really rely on you guys! Thanks for the support so far. In conclusion here is what I have done:

1. Replaced lens with a KHS-400C
2. Replaced chip on board (BA5815)
3. Tried CD's and worked but no dvd's

Honestly, I'm totally clueless as what I should do. Should I just buy a new laser? Should I buy a new BA5815 chip? I'm truly stunned and have no further idea of what to do to resolve the issue. I've looked up "PS2 reading cd's but not dvds" on google and everyone talks about replacing the laser. The only suggestion I have not attempted is pot tweaking and that is only because I'm afraid of completely ruining the lens. If anyone wants to give me suggestions on anymore troubleshooting steps, It would be greatly appreciated. Should I buy new laser/Ba5815?
Thanks!

The only thing I have read is a faulty lens. Should I just buy a brand new lens in the hopes it will solve the problem?

One last question, Anyone know where I can find the Magic 4 Ps2 Modchip diagram for a GH-013 motherboard?

 

Did you try DVD Video (nor -R or -RW)? And CD game.

 

Sadly have neither of those. I ordered a khs 400c and hope to see if it fixes issue. Will wait for them to Arrive.

Also for v4 mobo which chip is recommended?

 

Just use back the original part. Don't swap it, unless you know what you're doing.

Just saying, based on what I've read from other threads, such problems might be even related to problems with the mainboard (e.g. cracked solder joints).

 

use lens changer it fixed a console of mine that would not load since i used the memory card hack it was cool it was a 400c and would not load it was orginal so just reflashed it work's perfect. i then fitted a mobo and even better.
