SANYO CE30ld3BK QP5 on LVDS drive board keeps going faulty

[southtynetv]

Hi everyone,
                   I have this set in with no picture sound OK backlights lit, I found the FET QP5 leaky on the LVDS panel, after replacing it, the set ran for a few hours. On switching on the next day no picture again, after dismantling I found a pinhole in QP5, and gone s.c. Has anyone had this before any help is very much appreciated.
Kind regards Bill
