Sziasztok!
Szomszéd csaj kapott angliából egy 54cm-es KV21LT1U (U jelzés utal az UK (United Kingdom)-ra) TV-t, amit nem bír használni mert kábelt TV-je van és kell hozzá a VHF I,III sáv, meg a hang is 6MHz-es.
Még nem jutott el hozzám, de a sémáról megtaláltam, hogy az eredeti tuner BTF-EU601 ezt ki kell cserélnem BTF-EC401-re, ez meg is lesz talán bontásból.
6MHz kerámiaszurôt nem találtam a rajzon.
Menuben és a szerviz menuben nem allithato a tuner es a hangnorma, uj eeprom tartalmat irok majd, csak azt nem tudom hogy a processzor maradhat-e a régi, vagy kezdjem el elôször keresni bontásbol valakinél?
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.

Sziasztok!
A fenti gépben lámpát cseréltem. Bekapcsolás után a ventilátor felpörög, a " lamp/cover " pár másodperc múlva felvillan. Majd 25-30mp múlva folyamatosan világít, a stby lámpa villog. Mit nem végeztem el? Az ajtó érzékelő működik, máshol kapcsolót nem találtam.
