Hi all, thanks for having me here Smile I have a Vizio 55" M550SL that started developing horizontal dark lines across the entire screen, less noticeable in the center and becoming more apparent as the lines propagate outwards, any ideas? These lines are present on any input and also in built in netflix feature, they also appear over top of my menu button. I have a picture of the failure just not sure how to attach it correctly, thank you for any input you have! Smile

According to Shop Jimmy:
IMPORTANT: Horizontal lines on the screen are virtually NEVER caused by a bad T-con board. Horizontal lines indicate a defective LCD panel (screen).

Thank you, I will look into that, is it hard to replace the panel (screen)?

IF it is the panel, it will be harder to locate exact part numbered one and the price may not be to your liking. Then there is the problem shipping so that it arrives without damage.
Actually changing one is fairly straight forward. Just transfer chassis / boards, etc. from old to new.
