Sony 777ES laser

[djmiddelkoop]

My sony 777es player doesn't play SACD.
CD playback however is fine.

A SACD is not recognized, the dispay reads: TOC error *

Does anyone have an idea what is causing this ?
Do I need a new laser ?

Any help is appreciated.

hi
dont want to ruin your day but let me tell you my tale....
i had the same player,it was going to be the last one i brought as i loved the build,sound,everything,paid under £1800 for it.
anyway after 14months mine developed the same problem as yours then about 2weeks after that cd reply was getting to be a problem until that gave up also.
got intouch with sony as i expected alittle more then over a yrs worth of use out of there expensive,made in japan flagship model,moreso as my old english cottage industry built cambridge cd player was still working fine after ten years use!
sonys reply was...SORRY YOUR OUT OF YOUR WARRENTY PERIOD AND THE COST AND EPAIR IS DOWN TO YOU.
needless to say i wasnt happy with that,and after many heated disscussions then threats they agreed to foot the bill for pickup and repair,the technican who got in touch with me told me the transport assembly was worn out and that it would all be replaced,total cost £500,so thank god sony was paying!
anyway when i got it back,it broke my heart to do it as i really did love this player but i sold it,just couldnt get my head around how it could be worn out so quickly and the thought of footing that bill every one to two years put me right off.
now i dont do flagship models,just buy stuff that dont cost silly money that if it breaks after a yr then it doesnt owe me anything!...sad but true.
hopefully mine might of been a one off,anywaY i wish you luck with the repair!
all the best

Hi Dick,
My friend had the same problem with the Sony SCD-1 which is essentially the same player. Sony replaced the laser under warrenty, but it was close to the end of the period.

My freind has had 2x Sony 9000 with the same problems, Sony had replaced the first one with a new one and now it's playing up, now they said that their not doing the high end models anymore, and offer a much cheaper model, or to have his fixed with new laser and circuit boards, but they will not say if it will fix the problem, it looks to me as Sony are getting out of the high end because of the problems they are having.

Cheers George

Thanks a lot Smithie, Elso and George for your replies.

This is what I was afraid off, the laser assy needs to be replaced and it’s costly.


It is indeed sad that a lot of cheaper players work fine for years and the High end break down so early.
It is even more sad when the manufacturer doesn’t give the support a High end product deserves.
We don’t get our money worth.

Sony general deals with only 5 year support of spare parts.

I asked Sony here in the Netherlands and they don’t have any on stock.
The laser assy is KHS-180A, Sony #8-820-005-02.

I had the same problem. It is usually resolved by lubing the inside of the sled motor with spray deoxit and lubing the plastic gears in the sled assembly with moly grease, or else it is the laser. Here are the steps to follow. I resolved the SACD TOC read problem at the last step, but it is unlikely you have a bad solder joint on the Main Board unless you have been pulling it for mod work.

Good luck,

thanks Dave,
the link shows usefull instructions to follow.
Actually this looks more like a general way to check any suspicious transport with a laser.

I will try the lubrication anyway as it will do no harm.

[Elso Kwak]

Molykote lub is NOT for plastics but for "steelish" material. Deoxit into a motor I dunno........????
I guess you need the white grease for plastic or in this case I would use no grease at all. Thick grease actually increases the friction with bad results.
I can tell you stories about Pioneer transports.....
Very often it's a small dust or package material particle that has come between the toothes of the wheel.

Looks like they had it at one time....maybe they will get more again?

Good luck.

Here are some detailed photos of the sled drive mechanism from my SCD-1, i cleaned and lubed all the gears with white lithium grease.
