If you give it regular TLC, you may be enjoying it for many years to come.
But if there is a gremlin (or a leprechaun) in it, who knows? Ask the faeries...
I got the same problem for a long time, and have to squeeze the edge of the screen when it is jittering. I am confused about the procedure to fix it. Could you clarify to me which one is the cable and invertor to be reconnected? A pic would be great.
I did disconnect and disconnect the cables I can unplugged last time, and it worked for days, but it fails again recently, and become even worse... Don't know if I should totally replace it, or should try openning the cover for another time. Actually, I am watching a $50 screen to be bit now...
Thanks for your answer in advance.
