The lower boards are not buffer boards. Really they are just fancy connectors. Not much on them to fail. You need to replace the Y-buffers, if you were told to replace some buffer boards.

i see i am still learning lol
i replaced the one board to the right as i noticed one of the big heatsink was getting very hot, so i replaced the board

HOT is GOOD. Cold is not.

Try running it with the Y-main disconncted. You will not see a picture. Check Vs and Va are present and good. Count the blinks on that PSU LED.

Vs is 1.4V with or without connectors plugged in?

i changed the one of the long bottom boards over half the screen works. i started to check the connections on the bottom board and noticed a few of the were very hot



so i disconnected them and got the screen to do this

You either have a bad plasma panel, rare, or loose connectors on that bottom board.
Black bars are bad panel or board. But they're usually only 2"~3" thick if a bad panel.

DO NOT MAKE CHANGES TO THESE CONNECTORS WITH POWER PLUGGED IN!!! I CANNOT EMPHASISE THIS FURTHER!!! YOU WILL KILL THE PANEL.

thanks tom, i did replace the bottom boards with new ones it worked for a while, but noticed that the screen started to get the thick black lines down it, but what i did not do was replace this board



so i think i may have shorted the new bottom boards

No, you just need to re-seat the connectors on that board. The X-main in your photo is not at fault.

Also, make sure to always have the heatsinks on those boards installed when powering up.
