Does anyone know what kind off light bulb the size detector sensor in the ps x800 uses ?

I have been scrolling the service manual for a bit but I couldn't find it . I need to replace it but for that I would need to know what kind of bulb I need to buy. I did find some things about similar sonys but I don't know if they have the same detecting sensor or not. Does anyone have a clue ?

I would strongly recommend NOT taking this turntable apart and trying to tackle a fix. There is a possibility that you will end up with parts in a box and giving up.

A guy at work's Dad has one that he got as a hand-me-down. Its manual lift and play do not work. I opened it up and quickly realized I was over my head by a quantum amount. Replacing one tonearm lift belt (it uses two) took about an hour of manipulation, digging the belt off the bottom of the chassis, and supreme cursing. It got done. I buttoned the thing back up and gave it back to the owner. I did not fix anything. Some photos.

See where some previous tech hacked his way into the back end to find the belt? This is the "hammer-mechanic" level you may end up at, try to fix that sensor. :(

I have already worked on this and fixed the tonearm mechanism aswell as replaced the phono cable, the belts and some of the buttons. I'll be fine thanks for the tip though.

Also if manual lift and play don't work but you can get it to play high chance all it needs are a few new push buttons. I had to replace both horizontal movement andt fast buttons on mine.

Dunno if it's the same axial bulb as the 1000/1000A.

It is very possible. Do you have a picture of the sensor and board on the 1000/1000a ? If you do I could take a look at my 800 and see if there are any similarities or of the part numbers are the same.

Okay. Just a warning from a pleb when it comes to fixing linear trackers.

Good luck! :)

Sorry, I misread the model # in the thread as PL-L800, very different beast from the Sony PS-X800.

I can just imagine a roomful of Sony engineers, trying to design the most complicated analog consumer level plaything. It must have taken some kind of engineering just to figure out the assembly line process.
 
This means that if the arm tracking doesn't respond in either direction, the fault is likely in the tracking circuit under the deck. If one direction only, it could be that or a bad Hall sensor.

According to this illustration, the tracking sense is via magnet and Hall sensors. No optical involvement.

If you look closely at the photo with the pulleys, you can see the pickups next to the magnetic flywheels. Prolly adjustment and electrical signal alignment is critical for proper operation. :idea:
