Master tulong ulit... nagkaproblema ulit ung unit...

Pagka-ON walang sound at display pero pag tinaasan ko ung screen voltage... nagkaka-display sya pero may retrace lines tapos ung screen lumiit... mga 3 inches ang bawas sa taas at baba...

Napansin ko rin master pag-iplug ko ang unit na sa na naka-ON na ang switch ng ilang beses... naging normal ang display nya.. kaso pag pinatay u ulit ung unit wala na namang display.... gagawin u na naman ulit ang nasa taas..

Ano master problem nito? Salamat

(from normal display pag-iOFF u ang unit may mga horizontal na guhit kang makikita)
