Hello again!
I forgot to mention that two of characters(character 56 & 76) are not shown at all( these two characters are either clear or completely dark or with random dark lines or sometimes with somehow golden(!) lines), LCD (4X20) is black & white with no back light.

PS: And please excuse me for my terrible spelling & english. Some of my errors in previous message:
line#10 shows => show, quit =>quite
line#12 shadow => shadows
line#13 mentioned => has mentioned
line#16 encountered same => has encountered the same

Thank you very much
