    Sony VPCE range Board MBX-223 issues

    Hi folks I have a spillage damaged MBX-223 i3 CPU here initially was dead /no power. The bios pins and pad were damaged swapped bios from same model scrap board and repaired traces. Unit now powers up with no Video it only draws max 1/2Amp on the bench supply.
    The GFX core was 0v so after checking around the regulator (PU25) and replacing pr127 and also Pu25 Im now getting 0.88v- 0.90v on coil PL19 (GFXCORE) . The screen continues to stay black on draw 1/2a and after a minute or so fan spins very fast also it will not switch of using powerbutton but will switch on?.

    Any ideas would be great

                                        hola amigo, con el bios que subiste se soluciono el problema de que a los 30 seg aprox se apaga de una la compu? es el bios del ec? como lo programaste? muchas gracias!


                                        Hi friend, with the BIOS you uploaded, is the problem that the computer shuts off immediately after approximately 30 seconds solved? Is it the EC's BIOS? How did you program it? Thank you very much!

                                        in English please..
