Hi, I'm looking for some assistance from experienced people who might be able to help me and on how to troubleshoot an LCD TV and it's issues with the screen. One case that is for certain is the screen itself who has not been bumped into or any flaws. The screen issues are coming from the circuit boards/main boards or the actual graphic card behind the screen. Maybe the T-CON board is defect. This is a Philips 37PFL5603D/10 Full HD 1080i LCD TV. View: https://www.youtube.com/watch?v=VX2DBljihGA https://www.philips.co.uk/c-p/37PFL5603D_10/lcd-tv-with-pixel-plus-hd So what happened a couple of days ago is that the screen started to develop some blue or discolored lines/stripes, gradually starting to spread downwards vertically from the upper TV frame. I can show a screenshot of the screen and share it if there's people who are looking on this message, or who knows something about these issues. But the same situation with the screen in on the YouTube video. Just a different TV brand. The reason why I'm posting this message is because if I can use spare parts such as a new T-CON board which is for sale to solve these issues. I just don't know which one them I need yet.
