I was wondering if other main boards would be compatible with this TV. The mainboard it comes with is: WC3O03 - 04300 #EBT62383434. While looking for a replacement however I can’t seem to find any for sale. Does anyone know if another main board would be compatible with this TV, or where I could find this exact board for sale?
Goras Oleg the only possible substitution I can find is a EBT62297967. If you can’t find the proper board consider having yours rebuild or consider purchasing from ebay.com since there are still used ones (warrantied) available. A shortage of the main board is definitely indicative of LG having issues with it. I believe issues on this model were with the memory IC’s.
