Fix – Disconnect PWM BLU Pin (this pin causes dimming of the backlight) From Power Supply Board to Main Board

As stated before you will need to dismantle your Samsung TV to complete this fix. However, it could be the problem causing your TV to power cycle again and again.

Start by disconnecting all of the cables from the TV (including the power cord), and make sure you have a soft surface for the TV screen to lay

on; then lay it face down with the back towards you. There should be little screws all around the outside of the back portion of the TV, go ahead and loosen these screws until they release and come out.

Remove the back cover of the TV, locate the power supply board and the main board and you will see a thick cable running between the two boards which is actually six smaller cables aligned with each other.

Now, you can disconnect the wire cluster just from the power board side; (be sure to get a small pointy tool for this next part). After you disconnected the wire cluster, you will notice there is six pins holding the six wires in place on the conjunction unit.

Now you can look over to the main board to confirm this is the right wire as it will be entitled “PWM BLU”, back at the wire conjunction unit (counting from the top to the bottom) count down to the fourth pin.

With your little pointy tool, push in and up on the pin. This will release the hold on the cable (while still holding up the pin hold), and carefully draw out the appropriate wire. Then, use some electrical tape to cover the end of the wire you pulled out.

For peace of mind, this wire controls the dimming of the backlight. Therefore when you turn off the TV the backlights will stay on, providing a nice night light; however, if you do not want that, simply disconnect the power cord.

This very well could resolve the power cycle issue, as the Samsung TV could be reading this short as an error in the operation, therefore it keeps power cycling to try to fix the issue.

4. Samsungs Chips Overheating

In your Samsung TV is a microchip or more accurately, a chip is a set of electronic circuits on a small flat piece of silicon. On the chip, transistors act as miniature electrical switches that can turn a current on or off.
