display problem

[rohityadav]

Hi,
i am going through a strange problem Even D2H technician failed to solve my problem. I have two HD STBs. One is connected to TV with HDMI Cable and working fine. Other one is connected with tv by RCA cable and in this picture moves in frame after every 2-3 hours. Every time i changed the Resolution in STB settings. But again after every 2-3 hours i face the same problem. Picture moves after 1-2 sec. gap . i tried everything. Please note that there is no any magnetic field near STB . i changed RCA cable 3 times. Even try STB on another CRT TV, but problem is same. i there any setting required to solve this problem. Please help me.

Due to voltage variation the display IC may get affected. My best suggestion is, if you have warranty for your STB kindly proceed with the warranty service otherwise go for local service centerr
