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 gépbe kell nekem háttér ledsor. Az Alin találtam, de dilemmám van. Azt írják, hogy 32, vagy 36 led van rajta. Hogyan lehet kompatibils egymással a kettő? https://www.aliexpress.com/item/1005005579403823.html?spm=a2g0o.cart.0.0.42eb38da4YfWqi&mp=1 Rákérdeztem az eladónál, azt írta, hogy jók egymás helyett. Szerintetek? Előre is köszi a választ! |
Üdvözlet Mindenkinek!
A készüléken se kép, se hang, a led 6-os hibakódot villog./Overvoltage/Overcurrent Protection/.Mit javasoltok, merre kutassak?
