If you own the original V2 board (without the red dot), you cannot change the hardware (capacitors or TCXO). However, you can to gain 80% of the benefits.
If a firmware update fails and the TV will not boot, you may need to use a hardware programmer like the to directly flash the SPI bootloader and eMMC image. This is an advanced procedure requiring:
: Requires intermediate soldering skills to tap into the monitor's neck board or main chassis.
The updated BKM33B TV2 PCB includes refinements to the power sequencing circuitry to prevent the "red light, no boot" condition that plagued some earlier TP.MS638.PC821 boards.

The legacy board struggled with thermal throttling when driven at max transmission power due to inefficient linear regulators. The updated board replaces these with a high-efficiency switching regulator network. This modification drastically lowers operating temperatures, extends battery lifespan in remote deployment scenarios, and drops the static current draw during deep-sleep modes down to micro-amp levels. 2. Enhanced Signal Integrity and Noise Reduction
