I've carried it in my pocket for years, musta bumped it. Black stripes appeared on the LCD whether it was turned on or off. The best price I could find to repair it was $175. For that money, I'd get a new camera.
I found an OEM screen on ebay for 50 bucks. I figured why not give it a try.
Your step-by-step instructions inspired me to attempt this.
The only problem with the instructions was no description of how those locks work on the surface connectors. The big one was easy. I failed to observe that the small one opened from the opposite side. I ended up popping out that latch altogether.
A few minutes with a pair of tweezers got it reinstalled.
Otherwise a piece of cake! Camera works fine and I saved at least a hundred bucks.
If you need to replace the screen on your TZ5, do it yourself, it ain't too tough.
I made a sleeve from a plastic "Keep Off The Grass" sign to protect the camera in my pocket.
