#help I am searching for an LCD module part to repair a friend's tablet. Tablet is a Logicom Tab 76 The display is damaged, it's a 1024x600 7" display. On the back of the display is written LCM-RS070WS046-A0 2024-05-22 RS02 Any idea? I searched on aliexpress, ebay, google ...

Picture of the back of the LCD module
You can see written:
LCM-RS070WS046-A0
2024-05-22 RS02

It's even scarier when the JTAG is plugged! #FPGA

FPGA board on blue matt.
red/black crocodile probes are plugged
USB C as well
and a 5 pin colored JTAG header is plugged as well (FT232 FTDI cable)

And look at what I've just received ... 🎁 PCBs + stencil 😍 🍾 A few days after receiving the components from LCSC. 📦 It's still xmas! 🎄 #SucreLA #opensource #oshw #fpga

PCB stencils, a big aluminum sheet with laser engraved holes.

1 blue box marked "JLCPCB" on top of a brown box marked "JLCPCB SMT Stencil" on top of a wooden table.
