Hi i have a old ps2 50001 v9 with dms3 this dont read any disc since 2005, i used with hdd for all this time, my brother try to clean and calibrate lens with no sucess, and he broke dvd tray.

A few days i decide open ps2 to see, i not eletronic tecnical,but i good observer, dvd tray can be fixed provisory with isolate tape,lens my ps2 has khs-400c,i do a lot of tests calibrating and cleaning, with no sucess.

Cd/dvd can turns, but is not recognized and give me disc errors.

I want know ps2 V9 console comes with khs-400c lens? or person who installed dms3 changed my lens?

This lens is completly dead after 3 months with dms3,in a ps2 with 6 months of use.

I will change this lens for new khs-400c, this is best to do?

My ps2 can spin cd/dvd,can enter to see memory card files, only not recognize cd/dvds.

I think this is dead lens, but i dont know if is can be LA chip problem, i dont know much about LA.

I appreciate any help

Sorry for bad english[google]

Has the Romeo Mod (12V to 5V) been performed to the console? (Should've been performed as the mod chip was installed). All modchips at that time were known to crash the CD/DVD Mechacon which led to LA6508 chip and lens issues. So if it has not been performed, I would almost guarentee that it's a LA6508 and/or lens issue. I've also noted some V9/V10 models to come with either the KHS-400C or Sanyo HD7 lens. If memory serves me right, there was a program developed for the PS2 that allowed you to change the eeprom settings, which in turn allowed you to change the type of laser your specific PS2 utilized if needed. But it was also known to be a little buggy.

I would post links of further information on that matter but my post count prevents me from doing so. A quick google search on "Romeo Mod" will yield you more information on that matter.
