Hello friend to badcaps thank you for register to this forum.
I have this problem.

1- 24v go to 0v If have connected 4 flat cable panel and TV have only audio. And result D18 shorted.

If disconnect 24v cable to tcon have this: TV on only audio. And result d18shorted.
Vpres have short circuits, if disconnect 4 flat cable the diode D18 result good.
Vpres is shorted and connected to tcon lock the 24v in protection. Have solution for investigate this little board?

Thank s

you should cut the metal plate to have access to complete edge boards.. but if the short at cell row no way for repair..
1- remove caps and check if the short remain or not.. if it remain.. keep yours DM on the shorted reading cap and with yours finger tap on the front panel glass carefully at corner and middle .. you may have the short peep ton stop... maybe..
