Am acest tv led cu main board mb95m cu display ves400unds-2d-n02 sursa 17ips71

defectul consta in faptul ca porneste se aprind ledurile dar fara sunet sau imagine nici meniul nu apare ecranul blocat ca si cum

nu ar functiona t-con dar am 12v pe el functioneaza din telecomanda intra in st-by.Tensiunile sunt ok daca aveti un soft pe usb sa incerc.

eu zic sa verificati displayul,,poate a suferit de efectul gospodinei,,a fost sters prea bine cu lichide,verificati pe display ,pe t.con,trebuie sa fie ceva tensiuni mai multe,-15-17v,3v2,-27 v...............vizualizati cu atentie driverele superioare display,sa nu fie ceva scurt pe ele,cablaj topit,intrerupt.....
