Ok, there is a signal on the screen that has at least 20V value. Did you use a probe with voltage divider? |

Harry Can you explain or tell me what you been thinking or trying to do? Maybe i can do some helps on it. Did you have any ideas where we going or you are also testing everything and watching ICs like me. If you have any potential causes or doubts on any of Motherboard ICs then let me know. |
