#1 Cambridge CXC laser assy.

Post by pre65 »

"The Cambridge CXC transport seems good value, but mine has developed a fault, and after it has warmed up it skips a bit. :("

I've decided to do something about this.

By reading up I found the CXC has a Sanyo laser assy. I've removed the one fitted and the pictures tie up with the suggested replacement. £12.28 all in.

Should be here wk 2 2023, I just hope I can remember how it all fits together. :wink:

As an aside, the toroid Cambridge use is a secondary 10v @ 2A so I will leave that alone for the time being.

Hello,

Where did you find the replacement ? I'm interested too, as I've had this problem for a while.

Well, this is the info I got, but best check to see if yours is the same.

"The drive itself is covered in Cambridge labelling, but it’s a common Sanyo SFP101N, 16-pin. "

All the Ebay ones seem to come from China, as is the one I ordered from Amazon. I'm told it is now in transit, or was it a sprinter ? :lol:

The replacement laser unit has just been delivered, not in transit, but Volvo estate. :wink:

I've unpacked the unit and it looks the same, but won't attempt any actual replacement work today, except for changing over the four rubber isolators.

Well, I put it all back together, but the display reads "no disc".

Ho-hum, further investigations required. :(

I don't know that head, but check there is no shorted blob of solder that's designed to be removed after installation.

Thanks Nick, I found the "blob", but being heavy handed with small side cutters I've fuc*ed up the small pcb.

Another order to China. :(

What the hell were you using the cutters for? Just use a iron, and if needed some solder wick, but just the iron, if its free of solder will normally take it away.

I have ordered another unit, probably another few weeks as China seems the only source of such items.

I've received another laser unit from China.

I won't have time today, but possibly tomorrow.

:lol:

As a bonus, I've found some copper solder wick.

Nothing yet, just got home from the Indian restaurant.

Toilet roll is in the fridge. :lol:
