Re: lg ps3000
first i got a new multimeter as mine was not great then found 2 buffers blown on the top buffer board so removed some buffers from another board i had this is the first time ive done this took me a while but fitted 2 buffers tested again with meter and checked fine fitted buffer back into tv and result all worked
