LG LVDS FFC continuity

[t4796]

I've got an LG LA6230 with back light, audio but no video. I've tried another t-con same result.

Thought I'd check the lvds cable and I find some pins have no continuity. Is this normal?

Yes its normal some of the pins are ground.

Hmm, have you checked what voltage is on the other side of the Fuse on the Tcon ?

Re: LG LVDS FFC continuity

I thought that the pins should go straight through to either end of the plug?

I've got ~12v at the fuse. I found one of my Sony lvds cables was the same size and tried it with the same result unfortunately. I think the mainboard is at fault. I seem to read a lot of threads where LG mainboard have gone faulty. Wish I knew what component. Saw some people replace eeproms.
