lcd tv SAMSUNG LE40R71B relay clicking
I have this TV equipped with the source BN44-00134A.Tv does not start, it is heard how the relay is continuously coupling and disconnecting. The stable voltage drop is STB = 6.5V, P-ON / OFF varies between 0.2-2.5V in normal operation = 2.6V) PFC between 360-385V (when going is 382V). All electrolytes, secondary-primary, have been changed, except the 220uF / 450V which is ok. In this state, if measure the voltage on the pins 1-2 to optocoupler PCS802, the relay stay connect and tv work normally . I have replaced the PCS802,801, the ICS 802 (KIA431), the QP803, the QS801, the QS802 checked. If I stop it(unplugged) and I restart the tv in a few minutes, it works normally, if I leave it a little longer, the defect returns. Any suggestion is welcome, I do not think it would be the problem with the mainboard. Thank you!

Samsung LE32S81BX háttér egyik csöve nem világít
Sziasztok! A segítségeteket szeretném kérni! Először trafóra gyanakodtam, aztán a háttérre, most kiderült valamiért nem gyújt be a cső. Tudna valaki rajzot a Darfon 4H.V0708.661/A más néven V070-W04 inverterről? Nem találom, hogyan van a trafó vezérlése.Már guugliztam egy ideje, de csak a képeket találom. Köszönöm!!

SAMSUNG LE26S81 EEPROM TARTALOM
Tisztelt kolegák,
a címben említett TV miután az 5V szűrőelkója megadta magát, magával vitte az eeprom tartalmát, az IC501 24c256. Van 1 teljesen OK LE32s81 és a kis 26-os működik is vele csak az a baj, hogy az alaplapok kűlömböznek és a 32-nem nics flash meg 24c256 hanem SPI. Ha valakinek megvan az IC501 24C256-os tartalma legyen szíves töltse fel, kűldje el stb.
Az alaplap az BN41-00876A JASMINE.

üdv

PS
az SDA reset meg az üres eeprom tanácsokat előre megköszönöm, nem működnek
