Facing TV Problems? Ask a TV Technician.
Are you comfortable with removing the screws on the back of your Tv? If so you'll save yourself about $100 to $150 repairing it yourself. Most modes only use a 24 volt supply so it's not dangerous as long as you unplug it. Leave me a response, I'll give you the information you need tomorrow morn. look on the back for your TV's model and version number on the sticker
Well, all you need is a #2 (medium) Philips head screwdriver or power screwdriver to get the back off, and the main board you need to replace. There are several plugs that need to be unlocked from the board, and your hands are better at that than my hands - I can't feel anything through the callouses I have, but I manage those connectors ok.
You can do this.
Here's a couple pictures of how to remove the back cover of your TV set. I have more pictures of how to remove the main board. You should do this when you order/receive your main board, but I wanted to show you the procedure 1st - see if you can do the work confidently.
There are different main boards, depending on when it was manufactured. There is a bar-code sticker on all boards with the correct part number on it. That's the best way to find the correct part. All Samsung part numbers start with the letters BN, followed by 6 or 7 numbers, and ending with a letter. Here's a picture of one of the main boards in your TV set, along with a close up of that bar code.
Once we get that part number, we can google it for suppliers.
