When turned on, the screen turns on but then turns off: this LCD was turning on but after about 2 to 5 seconds it turned off leaving the screen completely black | When it was turned on while the lights were on, you could hear a low, high-frequency hiss, as if something was sparking, at first I thought it was the power supply, but when I put my ear close to the plate I realized it wasn't from the The power supply of this hissing was from the end of one of the lamps, so I disassembled and checked this lamp, which had an oxidized wire right after soldering its terminal, I removed the oxidized part, I redid the solder on the lamp terminal and the LCD started working normally again. . | ||
