Üdv Uraim!
Sony KV25C3.A szokásos táp baj + sorvég tranyó.
A táp megjavítva, 2SC3997 nem volt,- egy bontott AE2F-ből /csöves volt/-kibányásztam egy BU1015-öt!!
Hozzám így került és baj nélkül működött, a csövet leszámítva.Gondoltam akkor az ae4 is megy vele.
Ment is 5-10 percet, aztán megint táp+ sorvég.Nem melegedet sem a táp sem a sorvég!!
Kh-ra gyanakodva megjavítom,átforrasztom a sorvéget és a tápot is,/új BU1015/ tárcsakondik cserélve.Újabb próba ,ugyanaz a hiba.Időközben csak találtam 2sc3997-et, de azzal is így jártam.Lehet hogy a trafó szarakodik- pedig teljesen jól indul- vagy a sormeghajtás?
Help!
Hello
The TV does not show any sign of life , I started the troubleshoot as this , no power Led, no reaction when pressing the power button.
I checked the Power coming out from the power supply, the 3.3V_standby is correct and steady, then I checked the 1.2V_standby produced by IC6001 which Is good as well.
So I decided to control the main IC , IC4000 , he does not output any oscillation on the Xtal, Then I am now bloacked there.
The schematic is downloadable on this website , the schema is weird because the processor is not represented with any Xtal output, but obviously it has one.
Thanks you for your hint and help.

Azt hiszem a címben minden le van írva. Hozták ezt a masinát, hogy, ha olcsón javítható... :)
Kérdés, hogy a cső öregedett meg, vagy okozhatja valami "olcsó" probléma is?
