van egy tv philips 25pt4423/58 melynek mind a tápja mind a sorkimenö és környékén mért adatok kapcsolási rajz alapján jok.
Igy csak az eprom maradt de a problémám az hogy nem tudom mivel lehetne átírni ezt az epromot. Ha tud valaki kapcs. rajzot az írjon
Üdv urak!
Azt hittem nem tud meglepni egy ilyen,de mégis.
Szar volt a sortáp elkó.Ez szokásos.
Kicseréltem BC547-re,majd BD139-re az 5V tranzisztorát,100uF-ra az 5V 22uF-ját.Átkötöttem a biztit.
Ahelyett,hogy elindulna,semmit nem csinál,csak a LED világít.Kicseréltem a sormeghajtó optót,kimértem a megh. tranzisztort,bétája oké.Kicseréltem a Jungle IC-t is.
8V megvan,5V szintén,sortáp 97V.A sor BU kollektorán is ott van.
Azt figyeltem meg,hogy ha pár percig bekapcsolva hagyom rendesen melegszik a BU.
Trafós lenne?
Még sosem cseréltem ilyenben,max ha csattogott.
Ötlet?
Köszi!
