hi
i have a samsung lcd tv
it powers on with sound and backlight but no picture
all voltages from PS are good 12v 3.3v and 5v
whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v
i figured main board issue..so i ordered a used main board....when i put replacement main board in i still have same issue
no 12v at the tcon fuse
i disconnect the panel ribbon cables to rule out any panel issues and i still have no 12v at the tcon fuse
the odds of having 2 main boards with exact same problem is rare but could happen
could this actually be a bad tcon board? ..maybe is shorted out and not allowing main board to send the 12v?..or is this not a possibility.
thank you
