T-CON Board for TV 6870C-0402C 6870C-0402B etc. I saw on YouTube that replacing the T-CON board might improve the symptoms. I purchased this board on AliExpress and tried replacing it in a separate listing, a REGZA 55Z7 [Defective] TV, because the image wasn't displaying. However, the image still didn't appear after the replacement. I cannot identify the specific part that is malfunctioning, and since the replacement didn't work, I cannot confirm whether this board is in working order. Therefore, I am listing it as a defective item. The AliExpress product page stated that all products are tested before shipment. I will ship via Yu-Packet Post Mini. This is a defective item. No returns or refunds. Please understand the condition and shipping method before purchasing.
