How I repaired my Sony Handycam! :D











DISCLAIMER: The handycam is a high precision device. Disassembling voids the warranty! If your handycam is working, think a hundred times before attempting to open it. This article is for educational purposes only, and I shall not be held responsible if you ruin your handycam trying to open it.

In this post I will show you how I repaired my Sony Handycam CCD-TR516E. One of the rollers inside the tape deck mechanism had broken and the timing cam sequence was entirely off! I had to strip the deck down to its bare backbone to restore the sequence. If you're using this as a reference to repair your handycam, please be very careful with the tape deck. The components are miniscule and its very VERY easy to lose any of them. Besides that, there are flex cables and you could tear them easily. So, be very careful. Use the correct tools and do not attempt to do any of this if you're not confident.






One of the boards...











The CCD imager along with the lens assembly. This handycam has Nightshot IR imager that enables recording in complete darkness, ie, 0 LUX (luminosity).





























MEEEEEEEEEEEEEEE------>










MECHANISM CHASSIS ASSEMBLY ------------>
This is the lowest of the three layers of the tape deck. The motor on the left is the drive motor, which drives the tape. The motor on the right is the capstan motor, which connects to the timing cams (the 2 big gears on the right top). The timing cams control the sequence of motions of the deck (eject, for example) that takes place as a preparation for tape play or record or eject. The bottom center portion holds the video head drum.

LS CHASSIS ASSEMBLY---->
This is where the 8mm video tape cassette sits. The rollers on the extreme lower left and right pull the tape to the corners. The big black roller is the pinch roller. The white bracket is the base block assembly. Two guides that guide the tape through the head drum sit in the two grooves. The LS chassis assembly sits over the mechanism chassis assembly that controls the sequence of this layer.








And TADA!
Everything assembled! One of the guide rollers had broken. I reconstructed the broken part with alternatives.
