  2. This model uses four C-cell batteries, these have been in here since I was 10, hmmm... wonder if there's any juice left?
    • This model uses four C-cell batteries, these have been in here since I was 10, hmmm... wonder if there's any juice left?

    • Time to take the batteries out

      • Push down at one end of each row of batteries towards the spring

      • With the tension released pull out on the battery until it comes out

      • Repeat until all four are removed

    • Thumbs up to Sony for providing nice visual instructions for those kiddies

    • To remove the red back cover you need to remove six screws placed around the border of the cover. Note! The bottom 2 screws are longer than the other 4. These 2 are 35mm long whilst the other 4 are only 30mm long. Don't mix them up !

    • And voilà! Now we have a nice view of all the internal components

    • Remove one screw to take off the rear part of the carrying handle

    • We also gain access to the rubber microphone holder

    Be careful with that camcorder it is worth over $500 because it was used in the movie Pitch Black it's picture is the view of what the aliens point of view

    • To remove the speaker first you'll need to get some slack on the wire, do this by pulling it out of a plastic holder thing

    • Proceed to to lift up the blue chassis and remove the four screws holding the speaker down

    • These screws also hold the yellow speaker grill to the front

    • It was a bit of a fight but I was able to pull the blue chassis out of the front piece of the red case

    • There were no fasteners holding them together

    • Take out three screws to remove the main circuit board

    • Then unplug four sockets attached to the circuit board

    • And here we have the only circuit board in this device, don't see any big processors on it, I guess I can't turn it into a super computer :(

    • After unplugging the circuit board we can completely remove the speaker

    • It packs a whopping 3 1/2 inch speaker

    • Remove four screws to loosen the tape drive chassis

    • Then pull up and back to take the chassis out

    • With the tape drive chassis on its own we can look at Sony's weird button system, we also have the blue chassis with no components on it

    • Take out two screws to remove the tape reader/writer

    • To take the microphone apart just pull very hard on the red handle and it will come out, its held on by two tabs

    • Take off the yellow cover by wedging a flathead screwdriver in the crack and prying it off

    • Now we can look at a little microphone, and surprisingly it even has its own windscreen

    • So here we have it all disassembled, and THERE WERE NO 'WARRANTY VOID' STICKERS ANYWHERE!!!

Do you know where I can find belts for this device? I need both belts new.

Try to look if you can replace it with kind of mixed belt pack : https://www.ebay.fr/itm/Universel-50-Mix...
