Akai 50 inch plasma tv PDP5016H distorted display, especially bottom half

[Banzinator]

please see the pictures
it is an akai 50 inch plasma tv pdp5016h
the bottom half is distorted most of the time but the colors on the screen seem to aggravate it (when certain types of colors are being displayed in a movie scene or whatever it is not as bad and when other types of colors make it worse)
sometimes the top half is messed up too but it is mostly the bottom half
this started randomly, but the tv used to be fine
i did not change or unplug anything when this started that i can recall

so far i have only turned the tv off and unplugged it for 1 hour and plugged it back in to try to test it and it was still messed up (i also tried different DVI cables and settings on the computer and tested the computer with other displays to rule those out and the computer displayed fine on other displays and the cable and settings didnt seem to matter)

any assistance is appreciated

Bad lower Y-buffer or broken connection between upper and lower buffers.

Bad lower Y-buffer or broken connection between upper and lower buffers.

what is the suggested solution? i am experienced with computers but nothing about tvs... is it advised that i buy a y-buffer (after making sure it is for the exact model and version and revision etc for this tv) on the internet and replace it? is this something a novice can do?

is it not worth the cost at this point?

I'd say a novice could do it. Whether or not it is worth the cost depends on how much the part costs. It's probably got an LG panel inside it, and the buffer boards for LG sets are usually fairly cheap. I'd say about $30 to $40 for a used replacement board. You won't be able to find a new part though.

if it is the latter... just a broken connection, i dont have to buy anything right? just reconnect the ribbon cables? at worst i would have to buy a ribbon cable?

what % accuracy do you think this diagnosis is before i buy stuff?

thanks for assistance
