No audio, no sound | Hdmi ci shorting the 3.4v | 3.4v low, around 1.0v, beeping the capacitor tsound was a short, disconnecting the power supply board from the main board the short disappeared, we found 2 smd capacitors with a short on the back of the board, close to the plug that connects to the power supply , we put a voltage of 5v on them and the hdmi ci heated up, we removed the ci and the audio came out perfect. partial solution = remove the ci, however you will be without the hdmi function. total solution = replace the hdmi ci. | EC |
