Solved Samsung Tv Model Ln55B650T1F Won T Turn On Samsung Television

Chosen Solution

My Samsung TV model: LN55B650t1f won’t turn on. The standby light is on but nothing happens when I push the power button on the TV or the remote. I checked the remote batteries and I checked that the outlet the TV is plugged into are giving power. Any suggestions on why my TV won’t turn on? After searching online, I’m thinking I need to replace the power supply motherboard, part BN44-00268A, but I’m not 100% sure. I’m hesitant to purchase a replacement motherboard when I’m not sure that that will fix the issue. I can upload pictures of my TV’s motherboards later, I’m just not at home right now. Is there any definitive way to know that the power supply motherboard is the issue?

@emkf disconnect the power board from the main board and give it a try. Your backlight should show. That combined with your standby LED on, it is possible that this is a main board issue. Remember that it is the main board that tells the TV to turn on. Measure the voltages on connector CN801 and compare those to the values silkscreened on the board. Let us know what you find. not saying that it is not the power board but I hate to just replace boards for the sake of doing something :-) Not sure where your images ended up but to post them with your question use this guide Adding images to an existing question

There can be multiple issues with your TV, but here are the most common ones: The TV’s LCD backlight is dead or isn’t connected. This can be fixed by replacing the LCD/Backlight The motherboard is damaged or dead. There’s not much you can do about this, all you can do is repair or replace the board. its just easier to replace the circut board. An important piece of system hardware is fried. This can be fixed by replacing the dead/faulty part. If your TV is still under warranty, try taking it back to the store along with proof of purchase and telling them whats wrong Hope this helps!!!
