Hi, i have 2 docks which do not output a signal to the TV, but when i plug in a Switch it gets charged.
The Switch is not the Problem because it works fine in a known good dock. I also tried it with different switches. Do you know which chip is responsible for the video output in the doch ?
like i sayed above i tested with two differnt known good Switches and neither showed a picture with the bad dock. When i take my known good dock everything works like it should. So the switch is not at fault. It must be a fault on the dock mainboard.
Hi, most of the points i tested did not give me a reading and when it did it was only half or double the value you wrote down. While i tested i noticed that the marked (light blue)“caps?” were shorted to ground on both sides. Is that normal?
I also checked the Filters. They have continuity.
When you need the proper values i can write them down.
I measured a known good working dock again and you are right with OL at blue pin 6 and 8. I tested all testpads again and the pins at the big ics (m92t15/m92t17/VLI/ST) on the defect board but nothing obvious like a short or OL.
I have the opposite problem. 3 boards with a reading on testpad 6 and 8, probably gonna start removing ICs to see which one clears it. I see its its runs to the VLI ic but replacing that IC does not change the value for me so it has to be another crossover somewhere
