CK-5027 Z SAMSUNG
Tisztelt Fórum! A Ck-5027 z tipusú tv-nek nagy a sormérete és a VR801 5 Kohm potival nem lehet jobban levenni a feszültséget amit hivatalosan 125V-ra kellene állítani. A tápban szinte az összes elkót kicseréltem kivéve a 220uF/160V mert nem kaptam.Melyik alkatrész értékén változtassak, hogy letudjam szorítani a jelenleg 138V-ot kb. 120V-ra TDA 4601 IC-vel működik.Ha valaki érdemben tudna segíteni akkor tudok rajzot küldeni. A címem vz2@freemail.hu Tisztelettel:VZ
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!
