Hali!
Segítséget szeretnék kérni(mivel mérni az ilyet lehetetlen),hogy valóban t-con hibáról van e szó?
A képernyő egyik fele világosabb a másiknál,vagy netán cof hiba?
A szalagvezetőket megmozgatva nem történik változás.
Előre is köszi!

A hiba a lecsökkent cof (8V)feszültség volt,amit megnövelve a t-con panelon és potival beszabályozva megjavult a készülék.
