Too long cables between uC and LCD, metal front panel connecting to the LCD frame ground, etc.

make sure current path of load is physically separate from current path that powers LCD and 8051..i.e.use a star ground

Also that there is adequate decoupling and reservoir caps for the LCD Displays power.
