Now i have it (if somebody need it, please let me know) -Thanks to Voyager- but i can?t solve the problem: When i turn on the computer, the 16 character display flicks for 10 seconds. After this i can see the image in TV or monitor screen: new?brain?????????????????????????????????????????????????????????? ???????????????????????????????????????????????????????????????????????? ??????????????????????????????????????????????????????????????????????? ???????????????????????????????????????????????????????????????????????? ???????????????????????????????????????????????????????????????????????? ???????????????????????????????????????????????????????????????????????? ???????????????????????????????????????????????????????????????????????? ???????????????????????????????????????????????????????????????????????? ???????????????????????????????????????????????????????????????????????? Uppercase are converted to lowercase Spaces are converted to ? Numbers are converter to alphabetical characters (1 to q, 2 to r, 3 to s ....) but in 16 char. display all information is ok. It look like add 32 to ASCII code to display, but it is not so, because ASCII(1)+32=ASCII(Q) Q not q If i move just a little the computer i can see the correct character in screen, but not spaces, it still as ?. It like there is a bad contact in componet board, but i've check all contact and i can't found the fault. Sombody know this problem?? There is not the flat cable conecting diferent boards. Thanks and sorry by my english. Luis
