Re: Vizio M602i-B3 No Backlights
Ok ordered and replaced the main board. Now it gets weirder. When first powered on the back lights get brighter than before but then get dimmer and lightly flash occasionally. I press the menu button and the screen appears to lighten in the area of where the menu is supposed to be but still no picture or menu. I disconnect the ribbons one at a time below the tcon and this time nothing really happens. No one side grey like before.Leave a comment:

Re: Vizio M602i-B3 No Backlights
Got the new power board, at first appeared nothing changed. I then turned the lights out in the room and the backlights were on. So they may have been on before. The screen is completely black. I can not see a image with a flashlight. I disconnected the Tcon one side and the screen turned a dark blue. I'm thinking I have a completely different issue?Leave a comment:
