hi,
I have this 32lc2r from lg,which has not osd,the backlights are ok,no sound .no image.I've found out that +6v from the smps is missing.it seems that voltage is derived from +12v power supply which is present.the stage of +6v is made up with 2 fet's,but without schematic I can't repair it.I know lg doesn't supply the psu schematics so I hope someone could help.unfortunately I don't know the model of the psu.thanks in advance.

hi mike i know these tvs suffer badly from the caps in the psu they all look ok but need replacing anyway if this is any help rgds dave

Hi,
thank you all for the kind answers.I've replaced 1 bulging cap,but the true problem is +6v missing which is derived from +12v.all the other lines are ok including +12v.there are 2 burnt fet's so I can't read the type of them.anyway hope to find a good psu.thanks again.
