LG42PX4DV 3 board Change

Hi

Can someone just clarify something please, I believe the LG42PX4DV had a major problem where the repair is changing the sus boards etc.

Is it true the symptoms for this is that it blows the fuses in the sus boards, the reason why I ask is that I have one of these sets and none of the fuses are blown and I get nothing from the set, no sound or picture, the led goes from red to amber then to green then back to red.

I dont want to go out spend my hard earned cash on the boards to find it was a psu issue.

Can some please clarify the symptoms for this tv please.

Thanks in advance

i think the PDP used with this board is a v8, the 3 board kit i think you mean is for a v7, so it wont do.

have you checked the IPM's on the Y-sus for a short?

Hi Andy

I had a another quick look and found that there is no cable going from PSU (P806) to the z sus board (P1)

Without sounding stupid and without having to wait a few days for a new cable I am going link them up myself, now the stupid bit, do I simply attach:-

PSU (pin labelled vs) to x-sus (pin labelled vs)
PSU (pin labelled vcc) to x-sus (pin labelled+5v)

etc etc
