Before i knew it was a 3.3V screen i put it on 5V is this can be the problem? Did I fried it?
Definitely a possibility. This clearly is
a 3.3V unit, identified by the existence of "U3" on the back along with C1, C2 and J3.
R8 is the correct value for 3.3V operation - I cannot quite see what its value is on the illustration. R9 is zero ohms.
Remember that the correct setting of the contrast potentiometer is close to the "ground" end.
Connecting only pins 1, 2, 3, 15 and 16 is indeed the correct approach at this point. If you cannot get the first row of blocks to show as you turn the potentiometer down to the ground end, that looks really bad. It may be illustrative to see what is the maximum voltage you can find with the meter with the potentiometer turned to ground and measuring across the (various) ends of R1 and R5 (i.e., one probe on R3 and one on R5).
Should be nearly 5V (with 3.3V supply)!
