Salutare,Am un TV Sony KV-21FT2K (defapt bunica mea :) ) si am o problema cu el. Cand il pornesc dupa cateva ore de repaus, partea de jos a imaginii este "fugita" intr-o parte, si nu atinge baza ecranului. In timp, dupa vreo 20 de minute isi revine la normal. Are un caracter termic problema. Am luat si cartea de service dar as dori mai intai sa vad poate cunoaste cineva dintre dumneavoastra mai bine acest tip de problema si ma poate indruma mai aproape de rezolvarea problemei. Am multimetru/osciloscop in caz ca este nevoie.Va multumesc.

Schimba toti electroliticii in BV (presupun ca problema se manifesta pe directia sus-jos). Nu ar strica sa-i schimbi preventiv si pe cei de pe secundarul sursei si de pe recuperate linii.

Multumesc de sfat.Voi face asta si revin cu rezultatul. Am curatat de praf toata placa din interior si la prima vedere nu este nici-unul umflat dar pot fi uscati.P.S. Da, prolema este pe verticala.
