???????????? Fals. Tiuitul e de la transformatorul de linii, care functioneaza cu frecv. de 15625 Hz.
si se datoreaza vibratiei dintre infasurari. Poti elimina prin inlocuirea lui (cu unul nou) sau sa-l fierbi in parafina. (dupa demontare) . Nu este defect.
Am si eu un tv care tiuie,dar crede-ma ca e de la tub(l-au cercetat niste meseriasi si mi-au spus)-se aude exact din capatul subtire al tubului.Tv-ul are mai mult de 10 ani si nu a avut vreo defectiune niciodata.Nu am zis ca nu poate fi si din cauza a ceea ce spui tu.
Sa vedem ce spun astia pe net...
If it is from inside the set (and not from the speaker), IT IS IN THE DEFLECTION (probably vertical) (IMG:
style_emoticons/default/naughty.gif) or power supply. Either of these can vary
in severity with picture content due to the differing current requirements
based on brightness. It could be a power supply transformer, deflection
yoke, or other magnetic component. Even ferrite beads have been caught
buzzing when no one was looking :-). Any of these parts could vibrate if
not anchored securely or as they loosen up with age.
Some hot-melt glue, RTV silicone, or even a strategically wedged toothpick
may help. A new part may or may not quiet it down - the replacement could
be worse!
