Hi everyone,
I could use some help/advise on repairing my Technics SLP777 CD player.
It started skipping and taking time to read the toc.
I did some research online an found out it was probably the laser. Good news tho, I read that technics had used the Soad 70 laser assembly in a few models of that era.
I purchased a good secondhand lower model and started the laser assembly swap.
I had both machines side by side. I removed the cover off them both. Great news, like I had read the lasers assemblys were the same.
I took my laser assembly out it the 777 and replaced it with the good one from the lower model.
I swich on the power and inserted a cd into the draw. The cd spun up and went really fast. Then stopped and started to spin in the other direction. Strange.
I put the lower model laser back in to its original machine and it played fine. So I tried it back into the 777 again, Checked all the cables etc.
The same thing happened. Spun up really fast then stopped and spun in the other direction.
So now what. Well I tried my faulty laser assembly out of the 777 in the lower model machine. It played just like it did in the 777. Slow to read the toc and skipping especially when playing tracks towards the end of the disc.
Any ideas would be greatly appreciated.
kind regards

Hello. My experience with Technics cd players is zero, but I've seen on internet that these models of Technics cd player uses SMD capacitors in the disc spin motor. Maybe this is the problem.
Hi there, thanks for the reply. I had read that somewhere, but I thought it would be easier to replace the whole assembly which is why I purchased the lower spec model. I just don’t understand how the lower model CD player plays fine but the laser assembly doesn’t play in the 777.
