Hi, sorry i only can write in english. I have a compal motherboard, LA-6631P, i need help for this faulty. The mother not turn on, i dont have B+ stable voltage, only 3v in B+ line. The IC charger is correct, and 3 / 5v IC is correct too. I know because when i put 19v directly in B+ line, i have 3 / 5v stable in PL3 and PL4. When the 3/5v are stable i push power but not turn on. if only put voltage in DC jack conector, i dont have B+, only 3v y PR38. If i remove PL10, the board have stable B+ from DC jack. PL10 is for principal supply 3 and 5v, But the PU3 IC is correct because i have 3 / 5v stable when i put 19v in PR38. B+ resistor. I check in all B+ line, and separate all circuits supply from B+. But no have changes, only have B+ stable when remove PL10. Thanks for all. Regards. |
