Member: 2498972 Status: Offline Thanks Meter: 33 | Have you done any troubleshooting or are you just asking for a solution? The more info you provide, the better the answer will be. For the LCD, check the Chestnut IC (U1501) and let us know what you are seeing for input and output voltages. For the backlight, check the backlight circuit and filter (U1502) and let us know what you find. |
