On the 17MB62-V1 PCB, is a critical component. It is an 8-pin SOIC-8 surface-mount device. In most revisions of this chassis, U158 is populated with a MX25L80 (or compatible equivalent like Winbond W25Q80). This is an 8-Megabit (1 Megabyte) Serial Peripheral Interface (SPI) Flash memory chip.
Failing to match the dump to the panel will result in an inverted display, distorted colors, a mirrored image, or a secondary brick state. Step 2: Extracting the Physical IC
Reliability is key.

If you are running into specific issues while executing this repair, let me know: What is the on the TV's internal sticker? What programmer model and software are you currently using?
When the firmware on the MX25L80 chip fails, the TV will exhibit distinct failure modes. Technicians should look for these diagnostic indicators before desoldering components: On the 17MB62-V1 PCB, is a critical component

When these units encounter severe software corruption—typically resulting in the , a blinking standby light , or a completely dead unit —a USB firmware upgrade often fails. In these cases, the ultimate solution is to re-flash the U158 Flash IC (MX25L80 series) directly using an EEPROM programmer. This is an 8-Megabit (1 Megabyte) Serial Peripheral
Use your SPI programmer to erase the old data and write the new dump file to the chip. Re-verify and Solder:
Using hot air set to roughly 340°C with low airflow, gently heat the chip until the solder liquefies. Lift it clean away from the pads using tweezers.
Note: If the panel code does not match perfectly, your TV may boot up with an inverted display screen, incorrect solarized color profiles, or localized button maps that do not respond logically. Step 4: Erasing and Writing the Chip Payload
