Philips M224E5QST firmware read from an external SPI flash by in-system programming, with a timestamp of 20200802 in the name. ISP reading means the chip was dumped without desoldering, through the programming header or clip. Technicians write this image back to monitors with a corrupted scaler flash, the usual cause of blank screens or boot loops. Keep a copy of your own chip first, confirm the chip size equals the file size, and match the board number on the PCB.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
