Sharp LX830H - Brak obrazu po 2 minutach, dźwięk działa, LED zmienia kolor

Hi, everyone, This set came to my shop with the
following symthoms : 1. It can turn on, red light in standby
mode.
2. Press the remote, the Led turn to
green and can hear sound and has
clear picture.
3. After 2 to 2 minute, no picture but has sound. Led change to red. I think it mostly be the problem of
inverter. Hope anyone can upload the SM of this
model - Sharp LX830H Thanks a lot
