Its most likely more caps that are failed but have not blew up, replace all Samwha WB and WL brand capacitors on the power supply first.

Well that's just my opinion!

Since there is a LOT of board, can you help me to clarify which board is what

I mean, the one where the power cord go is the power board but there is only one HUGE capacitor, then, the wires goes to the central board, is that another power board?

thanks

I repaired a bad caps on the power board but the problem is still there, I have tested the buffer board (http://blog.coppelltvrepair.com/2010...-lines-in.html) but they seem ok too...

What voltages are you getting? Are you getting vs va voltages? No then try disconnecting y and x mains and see if it turns on. Still no va and vs? then focus there,,, getting standby on powerboard?. Is mains sending on signal? Your va and vs voltage reference is on a sticker back of panel.





Looking at the back of set your y main is on left connected to buffers. On right is your x main , center is power board and mainboard is obvious and below the powerboard. The smaller board next to powerboard with all the flat ribbons going to it is like your tcon in lcds. Btw this plasma has a split power supply design hence 2 boards might be 3 hard to tell with fuzzy picture. I worked on a 60 inch vizio that has a tripple power supply design before.
