Have TV Questions? Ask a TV Technician
Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems. In order to assist you, I need to ask for more info.
1) Where did you purchase this mainboard please?
2) Does the part number match the old board exactly?
Okay, Amazon has many sellers. Can you please tell me who the seller was?
Also, what were the original symptoms you had?
The reason I as is that an upside down picture indicates a mainboard that either has faulty software, or a corrupt EEPROM. Everytime we see an upside down picture upon replacement of the mainboard, it indicates the board was not a good board. So you were on the right track replacing the main, but the one you have has faulty software (perhaps was flashed for a different model), or the EEPROM (processor) is faulty. I would suggest purchasing the Mainboard from a reputable pulled/used parts vendor like Shop Jimmy, or TV Parts Guy.
I just checked and those vendors are out of stock. Another reputable one we commonly use is FTV Parts and they are showing this board as in stock for your set:
I would suggest sending the one you have back to the seller and purchasing from the link above as the upside picture does point directly to a faulty main.
