petreelectronic Posted January 13, 2012 Share Posted January 13, 2012 Cel mai probabil o lipitura pacatoasa. Examinati cu atentie si refaceti mai ales la procesor. Link to comment
ivanflorin Posted January 13, 2012 Author Share Posted January 13, 2012 logic asa ar trebui sa fie ...calea de stand-by ....dar am refacut ceva lipituri si teama este ca peste~ 1 luna vine cu acelas defecttv-ul functioneaza stas la ora asta....il opresc, ii dau drumu la intervale de 1.......30minute ..el functioneaza si cu sasiul ''batut''.....

dan cod Posted January 13, 2012 Share Posted January 13, 2012 Sigur cand pui capacul la loc se torsioneaza placa de aceea nu merge cu el pus ci face figuri.Lipiturile aiurea pot fi la smduri si e mai greu de vazut.Dupa parerea mea sigur este din lipituri sau traseu care se intrerupe la torsionare.

ivanflorin Posted January 13, 2012 Author Share Posted January 13, 2012 ms si pt aceasta solutie dar am scris ca la-m ''batut'' acest sasiu...dar smd-uri nu exista....... [sasiu made in china].. Link to comment
cristronic Posted January 13, 2012 Share Posted January 13, 2012 Eu cred ca problema este de la tranzistoarele acelea cu care se face tensiunea de 5V si cea de 8V,defect tipic la acest sasiu. Link to comment
tehtronics Posted January 13, 2012 Share Posted January 13, 2012 schimba si tranzistoarele V501 si V502, din sursa Link to comment
cristi71 Posted January 13, 2012 Share Posted January 13, 2012 Eu cred ca problema este de la tranzistoarele acelea cu care se face tensiunea de 5V si cea de 8V,defect tipic la acest sasiu.am avut acest defect. schimbat tranzistorii pe 5v si nu a mai manifestat defectul. Link to comment
