After uploading message via USB to RS232 adapter message saved successfully into 24C16 EEPROM. LED Matrix shows some letter completely but some are partially. Please suggest me how to solve this problem ?

If the display is showing something, it sounds like a hardware problem.
Most likely is a bad connection.

Try to identify exactly which LEDs are not working.

Please reply to this thread,do not create another.

As Phil said this looks more of a hardware problem. Is it possible to post picture of hardware to see the problem. It will help us to suggest you some better solution.
