Sansui TV with white lines on top image
 

Hello everyone,

I have a 27" Sansui TV that I bought from Sears brand new back in 2008. It has served me well and I only had to take it to repair once in 2010. It was working fine then one night we had an earthquake and when I got home to check on it the image was bad. It was all foggy. I always thought the vibration broke it that time. Anyways I took it to repair and fast forward 2021 and the TV still works.

No I´m going to describe what I use this TV for. Mostly games or movies. Sega Genesis , Dreamcast, Original Xbox, some PC games. Most of the use is from the PC that is plugged in via S-Video. I very rarely used the TV to actually watch TV. It could be once a week or a month. I preferred watching from the PC every single day. Now here´s the problem. Since some months I noticed that there are some white lines that appear on top of the image. But they don´t appear all the time. They only appear if the image is coming from specifically RCA, Component or regular TV antenna channels. They don´t appear from the S-Video signal coming from the computer. The question is this. Is the TV going to die soon? Or is the problem from the tuner or the connectors ? The weird thing is that it doesn´t happen with the computer. But yesterday I connected a Wii via Component(Blue,Green Red cables) and there were the white lines. What do you guys think ?
