Modded ps-2 v4 with dms4 lite se installed

I actually redid the wire so its all on top but didn't take a picture. Also moved the d and e wire away from the rest of the wire's so no interference. This chip supports dev 1, dev, 2 fast boot and normal boot. It boots ps-1 and ps-2 games flawlessly. Put a new 400B laser in it too. Sorry about the black tape. I know it's ugly but very functional.

 

Why did you put a 400B in a v4? As far as I remember those support 400C lasers. Just use lenschanger to change the type of the laser (you have 4 settings - 400A,B,open faced HD7 and closed face HD7 - HD7s do not work on a console older than v5,found this out the hard way.)

I quite ask this as 400B lasers seem to get to the point where only CD media works but not DVD media. I had a v4R 30004R console that did this,I just threw it in the closet to rust and got a v5 with a HD7 laser.

 

The 400c and HD7 also get that issue.

I have replace many failed lasers of those type too. The HD7 isnt the best laser IMO either, which you seem to rate so highly.

 

All consoles up to the G-chassis can support both the T487 and T609K lens.
The service manual for the GH-013 shows that the replacement part is the KHS-400B.

How did you know that it doesn't support a SF-HD7?
Given that it is a SCPH-30004 R, it could have either a GH-013 (D-chassis) or GH-015 (F-chassis). If it has a GH-015, then it would have supported the SF-HD7.
Externally, there is the chassis letter near the factory site code.

 

Some 30004Rs have a v4 board,thus GH-013. (mine actually was a GH-013,to begin with). So GH-013 ones would not support SF-HD7s.I think it's because of being too big. I actually did find this out the hard way by testing a HD7 in it. It won't fit because of its size,hitting the metal chassis. A 400C does fit though,but you'll really need to run Lenschanger. I threw mine out since the RAM chips cracked,but also I didn't really want to fiddle with a v4 (waaaay too much cables to pull and too thin).

As for 400C and HD7s,I rarely (let alone seen one) see any with a failed DVD lens (and CD being fine). 400Cs will simply click intensively trying to focus on the disc and not load anything (example being my silver v9 which I had to replace the laser on) and a HD7 will only load very few games. (had this happen on a VERY VERY beaten up v10)

 

Then you have not repaired enough ps2s, its 50/50 which one has failed in my experience.

 

Pretty much because any PS2 I get my hands on either works perfectly or has another problem - as far as I remember the last v7 (with a 400c,not chipped) I had was pretty beaten up to the point I had to replace the tray (it was literally broken in pieces) and replace the whole shiny shield,since it was heating up like absolute hell. Slims aren't much to work on either. Either it's the laser ribbon cable that I usually find broken (in one case it was literally corroded...) or the laser quits working. Speaking of which,most slims here have a PVR-802 lens,with about one or two being SPUs. The only time I got a v10 the laser was on its last legs,and the AV multi port was broken (even though it was in much perfect shape than my v7 - the v7 I got after had a literally mangled up AV port - funny thing it actually worked first try unlike the v10.),so it was quite worthless to use it in that state. Anything else was generally in good condition - my old v5 which I sold had a good HD7 open face laser that just needed some cleaning,my slim v15b only had a broken fan connector,so I connected the fan to the USB port,and that's pretty much all. The only time I've ever encountered such a laser that will read PS1/PS2 CD games was with a pack of TWO v4s. One got gutted because the video output was messed up(would give some gray emboss-like effect) and the DVD drive wasn't working,and the other one (the v4R) worked fine,but wouldn't read DVDs. I tried using whatever remained from the dead v4,including laser assembly,but the laser from the dead one didn't even work. Now that I found out about Lenschanger and FMCB,I quite regret throwing my v4R away,since I could just use a KHS-400C from my laser box (I have a box with lasers in good condition),but by the point I tried reviving it it was too late,RAM BGA chips were cracked. Oh well.

One strange thing though - in my town,open faced HD7s have near NULL failure rate,the closed face HD7s have a ~5% failure rate (v9 and 10s are rare here so that explains everything) and the rest are mainly KHS' lasers. Ah well,people have different experience.

 

I just dont think its worth commenting about how much something fails if you have not repaired many many thousands of them.

I have repaired at least hundreds, in my experience what you describe is incorrect. But I wouldnt go around in threads stating X or Y never happens with Z laser.

I have right now - 12 PS2's I have to repair on my workbench. I couldnt even guess how many I have repaired since they came out.

But to state a 5% failure rate - what are you figures? 100 consoles and 5 faulty HD7s? 20 consoles and 1 faulty laser? These are statistically insignificant.

 

It's a gh-013 it had a 400b in it. So that's what I used. It works great. Boots everything.

 

Most of the SONY optical blocks were found on older consoles, so they are indeed older.
SONY also stated that there were two possible types of lenses in their optical blocks.

Some part of the wear and tear observed would likely come from what the previous owner(s) did with the console. There may be also different levels of tolerance and wear, depending on the model.
One thing that I noticed, was that the 2nd G-chassis with MECHACON v3.8 (CXP103049-003GG/CXP103049-403GG, for only the SCPH-39000 and SCPH-39006 respectively) and later, have a higher jitter threshold in the test program.

 

The HD7 is garbage, I have drawer full of around 100 spent ones.
