I got this Plasma with no display. It turns on and off OK. I checked the 5V, 11V and 90V. The 90V is missing. What could be the problem? |

Take a moment to carefully observe the COFs Chip on Film. (Left Side black chips mounted on the flexible ribbon cables). Look very closely for burns and/or small holes in these chips. Look very closely for any ribbon cable damage on the connections to the Panel itself from the X and Y SUS. If any defect is seen, the Panel is defective. |
