Hi everyone I'm trying to fix my grandmothers tv and so far havent gotten very far. When it was brought to me it wouldnt do anything so I ordered a new power board and now I have power but no picture and NO blink codes the chevron symbol lights up and stays on when you turn power on and off when turn the power off, I'm not very advanced on the electronics end of life and if a board has a problem much past a capacitor or so I just get another one. I do get a short flicker on the screen but thats all it does. I'm guessing the main board? I have tried the reseting holding the buttons and no change thanks
