Hi again,

Exactly the same mate, so I suppose it could be very likely that something has been soldered wrong. Well I'll have a bash and retrace my steps, and if all else fails maybe take a good few close-up pics of the z sustain board to see if anyone can spot something I've perhaps done wrong.

C201

And also the controller board had these replaced:

C8
C9
C14
C15
C31
C39
C652
C653

Hi All,

so i've created an account with badcaps because I have an LG TV that needs fixing and I've seen quite a few threads regarding my TV. Hopefully I'll meet some new people, and more importantly get some good advice from others. =]
