The LCD display is not turning on, tested with another LCD.

Hello, I have a HTC Desire 820 today and I have tried testing it with another LCD, it turns on but no display on the LCD, touch screen / digitizer works though. Could it be a faulty component IC / chip on the logic board? I have triple checked all flex cables, plugs, connectors. No signs of any water damage on there too, including logic board. The original / old LCD has no display too, never did when it came in.

Answer this question I have this problem too

Is this a good question?

Same problem here, I don't know what caused it to not work after replacing with NEW LCD, even as you said touch digitizer works but no LCD light up. Did you figured it out after a year?


I think I either got a faulty screen or the LCD extension cable plugged into the LCD wasn't connected properly or damaged.
