ich hab ein großes Problem mit meinem Ambilight das mich langsam echt zum Verzweifeln bringt.
Es hat mich schon Nächte gekostet den Fehler irgendwie einzugrenzen aber jetzt komm ich einfach nicht mehr weiter.
Um das Problem einzugrenzen kann ich mit Sicherheit sagen, dass es zu nur Problemen kommt sobald ich versuche das Ambilight über eine Externe Hdmi Quelle zu betreiben.
Wenn ich den Pi direkt über den Fernseher laufen lasse kommt es zu keinem Fehler.
Das Bild ist in Ordnung und die Testvideos sowie Farbmuster werden vom Ambilight korrekt dargestellt.
(Feintuning hab ich hier noch nicht durchgeführt da es ja über Externe Quellen nicht läuft).
Nun aber zu meinem Fehler.
Sobald ich die Kabel umstecke kommt es dazu, dass die Leds flackern.
Dieses Verhalten ist besonders gut bei schwarzen Stellen zu beobachten.
Auch wenn ich Testbilder ansteuere z.B. komplett Rot kommt es immer wieder zu Farbwechseln (meistens 0,5 -1 Sekunde von Gelb oder Blau).
Bei einem komplett weißen oder schwarzen Bild kommt es immer wieder zum flackern/zittern der Leds.
Ich kann das über Fotos leider nur sehr schwer einfangen.
Da der Fehler intern nicht vorhanden ist gehe ich nicht von eimem Löt Fehler vom Pi zum Led Streifen aus.
Des Weiteren kann ich doch auch ausschließen das das Netzteil zu schwach ist ?
Könnt Ihr mir vielleicht weiterhelfen ich bin langsam echt am Verzweifeln und hätte aktuell nur noch die Idee, dass irgend ein Bauteil kaputt ist
Vielen Dank für Eure Hilfe.
Ich hab mich beim Kauf der Teile direkt an die Anleitung gehalten und folgende Teile gekauft:
