LG 50PG20 plasma thin line going across screen

[zell66]

I have a LG 50PG20 tv, I just replaced the power supply board and got tv to turn on, but now there is a very thin (about 1/16") going across tv screen. Any ideas on what this is and how to fix it?

Did you happen to take the ribbon cables off the buffer boards? Maybe try reseating the offending cable.

yes I removed all ribbon cables from power supply board. That could have an issue with one thin line across tv???

No I meant the ribbons that go into the panel directly. They are copper colored. On the far left.

Is the line going from left to right or top to bottom?

It could be a bad plasma panel. There is a small chance it is a Y-buffer fault but that is very rare.
