I have a problem with below code and i don't know how to solve it.
When start the power on all works ok.But if power of for 1-3 sec and again power on the LCD show chinese and the program not work.If the power of is largest from 3 secs all works ok.
The pic is 16f84a.

Code:
	DEFINE LCD_DREG	PORTB	'Selection of the port B
	DEFINE LCD_DBIT 0	    'Selection one RB0 with RB3
	DEFINE LCD_RSREG PORTA	'RS on port A
	DEFINE LCD_RSBIT 2	    'RS on RA2
	DEFINE LCD_EREG	PORTA   'E on port A
	DEFINE LCD_EBIT 3	    'E on RA3
	DEFINE LCD_BITS 4		'Mode 4 bits
	DEFINE LCD_LINES 2	    '2 lines    
	DEFINE I2C_SCLOUT 1
