Sziasztok!
Ilyen hibám még nem volt!
A TV bekapcs, amint a kép megjön, a TV kikapcsol, de csak akkor, ha antenna van bele dugva, és csatornán van. Kettőt villog.
Ha nincs antenna, akkor megjön az OSD, mutatja, melyik csatornán van, és addig megy, míg az antennát beledugom, megjön a fény, és rögtön kikapcsol. Úgy veszem észre, hogy a képernyő kivilágosodásakor kapcsol ki. Ha leveszem a G2-t, akkor megy addig, míg ráadok annyit, hogy megjöjjön a fény, és rögtön kikapcsol!
Mi okozhatja ezt?
Köszönöm.
Üdv: formasu

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.
