Lost 4 electronic devices on the circuit. Samsung TV has a flashing standby light, some blinks are faint and some blinks are bright in a random no pattern order. I need some basic troubleshooting steps/advice model UN65H6350AF
So shortly after posting this question, I went ahead pulled the power supply board and noticed it was charred In the top left corner (in pic) right behind the plug input. I replaced the power supply board as of today, and the main board is making an intermittent “spinning” sound. Coincides with the flashing standby. I believe you are correct with the main board suggestion and I think this may be part of the problem. Also, there seems to be multiple part numbers on this main board.
Hi, Was the TV turned on at the time or just in a standby state? If it was in a standby state, this may have limited the amount of damage due to the power surge. If it was on the damage may be more extensive. Disconnect the power from the Tv and then take the back cover off and inspect the power board for any obvious signs of damage. i.e. burnt or blown components. Also check over the other boards as well to be sure. If in doubt or not sure, post some close up pictures of the boards and hopefully someone may be able to assist. Here’s how to do this. Adding images to an existing question Also depending on the make and model and age of the surge protector, “some” manufacturers of surge protectors offer cover to electrical devices damaged by transient voltages (their term) Here’s an example only of what I mean It may be worth checking if this is available on your particular surge protector. Just a thought
drapsag99 Samsung does not officially use blink codes for error codes. In your case, remove the back of your TV and take a look at the boards. Since your standby LED is flashing it is entirely possible that this is a main board failure. Like @jayeff mentioned, post some good pictures with your question so we can see what you see. drapsag99 not quite sure what you got going on here. Your main board appears to have some water stains (high humidity?) as well as some dark areas (overheating?). See if you can provide us with some pictures that show a better view of both sides of the board as well as all the other boards.
