Recently my laptop screen went black, but image appear in the back. The only thing that didn’t work was the backlight lamp, so I order a new one. I tested outside and replaced this new lamp.
Assemble everything and then when I turn the laptop on the lamp give light but only for a second or two, then goes off, then turns on again when windows starts and turns off until I restarts the pc.
This could be the inverter, and I order a new inverter, when I swap the inverters it happens exactly the same. The only difference is that the new inverter does less noise.
Now when I disassemble the lamp from the screen to test, it works fine with either inverter, when I assemble the lamp in the screen it turns on and then off.
Any idea?
