Sony kf-50sx100k Nem javítom tovább, Eladó egyben
Üdv kollégák! Ügyfél azt mondta, hogy nem költ a TV-re, inkább eladja. 20.000.- Ft-ot kér érte, elméletileg nincs más baja mint a kiégett izzó. Az előbbi oldalon 20-ért lehet venni hozzá izzót. Ha érdekel valakit, Fejér megyében Adonyban van a készülék. Üdv Zoli
