Eye laser of vintage systems?

[Sega_Naomi]

hey guys

I was wondering is the laser part of let say a Sega Cd is easy to fix?

Because im a casual Vintage gamer & it always scares me that one day will come
that it's gonna be rarer & rarer to get a working sega cd / sega saturn / jaguar ec....... & fixing things will become Non avoidable.

so i was wondering if it's possible to fix laser (bad reading, skipping) ,

there must be Laser parts that sales like generic brand ?
and you can just swap the defective part?

let me know on this thanks!:)

www.electronix.com has laser pickups. the segaCD model 2 laser is like 10$ and a turo duo laser is around 18 or so. they have quite a few lasers ro choose from

[evildragon]

there's two different types of assemblies for the model 2 Sega CD...

[Mobius]

Yes, you can just swap out the defective laser for the new one, it's very simple. I did this with a TurboDuo and a laser from electronix.com to fix an issue with it not playing redbook audio properly. You might need to tweak the potentiometer a bit, though.

Which lasers are used by the rev. 2 Sega CD?

Both of them.

[Computolio]

Any news?

[evildragon]

I'm so sorry, I totally forgot.. I'm not going to be seeing these systems for a week.

Does anyone know what laser is in the TG16/CD unit?

Does anyone know what laser is in the TG16/CD unit?

KSS-162A

I had one on back-order from Electronix for 9 months before they finally acknowledged they can't get them any more...

There is also the KSS-220A - which costs around $50. They may have them at Electronix.

Which lasers are used by the rev. 2 Sega CD?

Mine has a SOH0T4. I don't know which revision it is, thought. Model number is MK-4102 if that helps. For some reason, the image in electronix.com doesn't match, but I suppose it's just a place holder.

Some other laser models:

Sega CD model 1 - KSS240A lens

Turbo Duo - HOPM3 lens

PlayStation:
SCHP-55xx to 900x - KSM440ADM drive or KSM440AEM drive (KSM440BAM drive also fits but needs extension cable).
SCHP-3000, 100x and 500x can use the KSM440BAM drive but you need to replace the top cover of the BAM with the one from the original drive mechanism (KSM440AAM or KSM440ACM).

[izarate]

Both of them.

I found out that some Sega CD 2 have the Sony KSS210A while others (like mine) have the Samsung SOH04T. I don't know which revision is which, thought.

EDIT: I found out!
Sega CD 2 rev.1 (silver ring spindle) Samsung SOH-04T
Sega CD 2 rev. 2 (all black spindle) Sony KSS210A lens, Sony KSS210B lens

More lasers:

Sega Saturn
rev.1 (oval buttons): JVC EMW10447, which is physically the same as the OPTIMA6. JVC OPTIMA150S could be used as a sustitute.
rev.2A, 2B (round buttons): JVC OPTIMA6, JVC OPTIMA6S. JVC OPTIMA150S could be a sustitute
Sanyo trapboard rev.: Sanyo SF-P101-15P, Sanyo SF-P101N-15P


Sega Dreamcast:
Yamaha drive (round CD pickup): NEC SPU-3200 lens, NEC SPU-3201 lens
Samsung drive (square CD pickup): Samsung SOH-R48 lens
The Dreamcast drives are a propietary design and there is no way to get the whole mechanism unless you take it from another Dreamcast.

X'Eye: JVC OPTIMA6, JVC OPTIMA6S. JVC OPTIMA150S could be a sustitute

Goldstar 3DO: Sanyo SF-C93

Xbox
Phillips VAD 6011/21 drive: Phillips SPU-3141
Samsung SDG-605/B, 616T, 616F drives: Samsung SOH-D12 or SOH-D16
Thompson drive: Thompson TOP60

Xbox 360
Hitachi GDR-3120L drive: Sanyo SF-HD63 or Sanyo SF-HD67 (replacement)
Samsung TS-H943 drive: Sanyo SF-HD67 (replacement)

More models:

PlayStation 2
SCPH-10000 to SCPH-3000x: Sony KHS-400A lens
SCPH-10000 to SCPH-3500x: Sony KHS-400B lens
SCPH-10000 to SCPH-5000x: Sony KHS-400C lens
SCPH-10000 to SCPH-50010 and SCHP-3000xR: Sony KHS-400R lens, Sanyo SF-HD7 lens(replacement)

KHS-400A can replace the KHS-400B only if a thin metal plate is taped to the side of the housing to form a metal corner like the B one, but it can’t replace either KHS-400C or R because of its thick base.

KHS-400B can repace KHS-400A without any modification but this model is not suitable to replace the C and R models due to its thicker base.

KHS-400C is thin and therefore can replace the A and B model as well as the R model.

KHS-400R is also thin and can be used in place of the C model as well as the A and B models. This model has a direct replacement from Sanyo bearing the model SF-HD7.

SCPH-7000xCB (PSTwo yellow box): NEC SPU-3170 lens???
SCPH-7000x (PSTwo): Mitsumi TDP-082W drive, Mitsumi PVR-802W lens
SCPH-7500x (PSTwo): Mitsumi TDP-082W drive???, Mitsumi PVR-802W lens
SCPH-7700x, SCPH-7900x (PSTwo): Mitsumi TDP-182W drive, Mitsumi PVR-802W lens
Some PSTwo have the Sony KHM-430AAA drive with the Sony KHS-430A lens. The Mitsumi and Sony models are interchangeable, but not the NEC models.


PlayStation 3
Sony KEM-400AAA drive, KES-400A lens, Sony KEM-410ACA drive(replacement)

[Mobius]

Excellent info!

[snume]

So, now where can we buy a Sega Saturn laser pickup (Optima6)?

I have found a ew on the net, around $35-$50 seems a bit high, but if that's all that's left out there.

[Tokimemofan]

Here are some that I have seen

Sega CD Type 1:
JVC Optima 5 (Uses 2x Stranded wire cable)

Sega CD Type 2:
KSS-210A (Uses 2x Stranded wire cable)
KSS-240A (Uses a White ribbon cable)
JVC Optima 6 (Uses a White ribbon cable)

Sega Saturn Type 1:
JVC Optima 6 (Uses a White ribbon cable)

I think the laser part is very hard to fix.

[megasdkirby]

I think the laser part is very hard to fix.

It's actually one of the easier things to "fix", since it's mostly replacing the defective part with another one.

Hello,
I've made many purchases from those guys:
http://www.libertye-online.com/

they have most of those laser lens at very good prices and when installed all worked like a charm

be the force with you...

[omp!]

Sorry for the bump of an old thread.

I tried a Optima-150 in a Sega CD2. I ordered a Optima 6.....got sent the wrong one, some funny bastard replaced the sticker on the laser or it has been incorrectly marked as a 6, the box it came in said "Optima 150".

It does not work. I have temporarily used one out of a Saturn (Optima 6) and the console works, I just wanted to replace the one I borrowed from the Saturn.

One thing I did notice on the 150 laser though was there was no solder bridge, there was a spot for it but it wasn't bridged. I have contacted seller for the correct laser and a replacement.

With the 150 in the Sega CD2 it spins up as if trying to read the disc. If I turn the machine on with the disc in, it pretty much straight away says no disc. If I turn it on and then put the disc in, it just tries to read, spinning the disc doing nothing.

[APE992]

The 150 you got without the bridge probably had it removed due to being a used laser or pulled from a working console/assembly.

Shame you can't use a KSS-210A. I have a dead SegaCD2 here with an entire laser assembly I could ship out but it uses dual connectors and not just a single ribbon.

[omp!]

Yea, I am not sure what the go is, not happy about it anyway as I have done my money on it. They would want it shipped back and yadda yadda. I saw another seller that sells the Optima-150 and the laser they have doesn't have a solder "blob" but a "static protection bar" in the socket.

The Saturn I got the laser from was just a parts unit anyway, it is missing a power supply. It was an American console at the video game shop I do repairs for, some Galah plugged it into the power point without looking (live in Australia) and blew the power supply up. They asked me to repair it for them and I looked at the power input and noticed it was an odd shape (flat one side of the figure 8 connector, in Australia it is rounded both sides), then saw the specs "input 120v"...... They gave it to me for parts.

Anyway, bit off topic that....

I believe I purchased the Sega CD2 lid and spring from you from Assembler forums?

I have another 2 Sega CD2's to fix up, (both use the Samsung SOH-OT4 laser) one needed the lid, the other needs a new laser, which I have ordered (different supplier) hopefully I have better luck. The supplier of the Samsung laser also has the JVC one so if it works out I will get one from them. I have confirmed both Sega CD2's work as I swapped the laser's back and forth.

I could use a KSS-210A. I can get it new from Liberty Electronics for about 20$ so if you can make a better deal while being shipped to Canada, I'll take it.

That you did, poor little guy met his demise at the hands of a NES power adapter. Nintendo sure did love AC over DC.

Hello folks
Yep another bump of this thread.
I had trouble getting the Samsung SOH-OT4 laser for my Sega CD2. It never showed up so I had to go elsewhere but had trouble finding it. I did find however Samsung SOH90-T4N quite easily. Some sites (mostly Russian?) showed it as SOH90-T4/SOH-OT4.

I thought, with the luck these Sega CD2's have given me (bad), I had nothing else to lose. I bought it from Liberty electronics as I had luck with them on the Optima-6S laser to fix another Sega CD2 (the only downer was they sent me laser only not the whole mech as I paid for).

Well I installed it this morning and it works! So if you have to replace the laser in a Sega CD2 fitted with the Samsung SOH-OT4 laser, the SOH90-T4N will work. Strangely the box says SOH90-T4N where the label on the laser itself says SOH-OT4......

The only difference from the original laser is this one has a plastic body, which is slightly larger and the laser head is a bit wider. This is all that probably distinguishes from the 2, pin for pin they are the same.

To install it I had to pop off the gear that moves the laser, whereas usually you could just wiggle the metal bodied one in place.
