OK then maybe you need more hysteresis to your power up cycle, which is to say the rate the voltage ascends from zero to operating voltage. Many MCU do not like slow power up, which is why PIC has PWRTE in the configs, it allows power to stabilize before PIC boots, or there may be RF running in on the power causing headaches, you did bypass the power leads with .01 µF caps yes? A ferrite bead there wouldn't hurt either.
And sometimes when powerup, the RX transceiver does not blink ( pic and LCD working OK ).
I'm using DEBUG/DEBUGIN instructions to avoid issues with Hserin/Hserout.
Be mindful of the Port Idle state, whether using hserin or debugin, True is supposed to Idle high and Inverted is supposed to idle low. So use the state which agrees with your receiver's requirements.

If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.
