Problem like screen graphic issue 

In this video, there seems to be screen problem in KONKA 48" LED TV but it actually is from main board.
As the regulator(1117) shows DDR 1.5v, here it can be replaced with buck converter module(1235).
Sometimes regulator shows unstable voltage as it carries high power for long time. In some case this issue is seen if main chip receives high current.
Where, 1117 can carry 800mA of current and 1235 can hold up to 2A respectively.
We can use 1235 module for various voltage outlets.
