Hi
I got a Samsung LED TV EU55SJ9000L i see the picture verry vague the back lightnig is working but the brightness control is not working.
When the brightness is adjusted from 0 to 100% no change in brightness.
I changed the T-CON panel but still the same.
My question is which part is responseble for the brightness control or how is the brightness adjusted?

Sziasztok!
Gondom adódott ezzel a masinával. Még készenléti állapotig sem jut el, pedig a tápegység mérve jó. Kiderült, terheli valami a 12v-os ágat.
Végigkövetve eljutottam a t-con panelig, ott egy zárlatos "valamit" találtam. Itt kezdődnek igazából a gondok, hiszen semmit nem találok róla a neten.
Felirat mindössze ennyi rajta: 58AK igaz ez a "K" is fordítva szerepel.
Ismeri valaki esetleg?
Köszönettel: Kiss Z.
Sziasztok!
Tud erre valaki megoldást? Végigolvastam a service manualt, de nem tudom aktiválni az alapmenüben a csatornák beállítása menüt. Köszönöm!

Sziasztok!
Előzmény kis idő (kb. 10 percen) után "hangyásodik" a kép. Újra bekapcsolás után szintén megismétlődik elmondás szerint.
Jelenleg már be sem kapcsolható. Tápfeszültség a készenléti 7,5V illetve On állapoti 11,8V helyett 9,5V mérhető.
Ha a digi panelról mindent lehúzok akkor is ugyanennyi. Ha digi panelt lehúzom a tápfesz 12,8V és a háttérvilágítás bekapcsol.
Egyenlőre rajzot nem találtam, pár feszültséget mértem. Több IC-n 3,3V-ot is mértem, IR vevő fele is. Púpos (feltűnően) kondit nem látok.
Bármilyen segítséget szívesen fogadok, amit előre is köszönök.
