The battery in my S22 had swollen enough to pop the side edges of the back cover. On disassembly, the front face of the battery was bloated to a point where a suction cup was of no use. I used the isopropyl alcohol as directed. With picks, then spudger, the bottom right corner was lifted to where the right edge could be accessed and raised. Excellent Guide!

Should have read Glover's comment.

Looked for the middle screw but the black tape covered all appearances of it. Lifting the mid-frame out of the case snapped the mount. However, there was plenty of support with the ten screws and no lasting damage to the reader.

Used the guide to replace the battery. Could not get enough separation using the blue spudger. Used the metal spidger to get things started then switched to the blue picks. Afterthought, Warming the bezel would have helped.

I needed to replace the motherboard on my FZ1000 and immediately ran into three issues:

1. I managed to destroy the ZIF ribbon connector on the The camera motherboard has three types of ZIF ribbon connectors, none of which the reference information provided adequate information. The one on the motherboard that connects just under the eyepiece has a black release bar 'On the Same Side' as the ribbon. The ribbon is folded and obscures the operation, so proceed with care. Tweezers are useful.

The two other types have release bars Opposite the ribbon. The black bar version seems stronger than the white. The white one also seems to get brittle with age. Proceed with care.

2. The screws are of two types: coarse thread and fine thread. Keep track of what goes where.

3. Lifting out the motherboard seemed to have a lot of resistance because of an adhesive patch on the backside and multipin insertion connector near the top edge and to the right of screw-hole.

Actually, Panasonic does have the part for sale. <https://panasonic.encompass.com/item/102...>

STOP. As noted above…Use the Video Method. When I was finally able to begin detaching the screen, the glass separated off, while the screen remained attached. This action sheered of the connection to a front-facing sensor which remained firmly embedded by adhesive to the front glass.

In retrospect, removing the main board, heating and using picks from the back worked with somewhat less effort and better control.
