i have a Hitach HD44780 Compatible LCD from pvc
the problem is that when i bought it and connected it to the supply the test screen appeared . but when i repeated this the next day there was nothing (no test screen) and i discovered that when the supply voltage increases above 5v which should be its supply voltage some blocks appear and then disappears quickly. so i don't know if it is damaged or not?
i hope u could help me
Thanks in advance
