Hi,maybe the new board was taken from a tv with a different BOM,so you have to write into the tv's memory the right display option code;look at the small label on the bottom corner of your tv,you'll see a three digit number,then with the tv on,digit on the remote '062598MENUxxx' where 'xxx' is the above mentioned number;after, the tv will go into st-by if everything was done correctly.Turn the tv on and see if the image is right.Hope it works.
