neovia SL-42vk10 parts

[ken]

hi again,
i need to know if LG manufactured parts for neovia SL-42VK10. my tv would not come on but the on led would flash. i asked for diagnostic and qoute/price but i did not agree to have it repaired. they said it was the defective power board but the price was too expensive to repair. i decided to to the job myself as i deal with electronics at the local hospital. they returned a tv that is not mine, exactly the same casing but all internal parts are LG and the internal serial number does not match my casing serial number. the sliding logo has been stuck with silicone. ive checked the internal serial number that is PDP42V5 and found that this model is a clone (external). they are in for a fight now .
i need advice and help
thanks kenneth
