Please use a complete sentence.Yes,but it seems no directly connection to them
Hello Sir,Please use a complete sentence.
The display is not directly connected to the back lights. "Yes" what? Is the problem the back lights or the display? It's a little like a refrigerator when the light goes out. Sure, it's not working from some perspective. But if it is still cold, then the refrigeration part is still working.
Hello MrSoftware,Thank you for helpIf pressing on it makes it work, it is probably what is called a "cold solder joint" or a cracked solder joint. See if you can figure out the exact spot that you press to make it work. Get it to the smallest area possible. That will help you figure out where to look closer. The good news is, if it is a cracked solder joint, you can often fix it simply by re-melting (reflowing) the solder at the cracked joint. This happens frequently in circuit boards that get a lot of temperature changes, and/or a lot of vibrations.
