Thanks mr. mon2. it is possible because of the under line. I cannot measure it since it was shorting the 5vLDO from ti [B]TPS51285B[/B]
Which was also shorted. so i guess you are rightThanks mr. mon2. it is possible because of the under line. I cannot measure it since it was shorting the 5vLDO from ti [B]TPS51285B[/B]

Hi, it was cheaper for me to replace the charging port now the issue is sporadic, I have tried the diod mode with no success, i can try again tomorrow, if any other idea i will be happy to try
I can also try a dirty fix jumper wire from dc jack to ps_id line if i can be sure from where to whereLast edited by koby058; 01-30-2024, 02:46 PM.
