I have a Samsung UN55ES6150F TV with a BN44-00503A power supply board and a BN94-05656D mainboard.
An HDMI connector on my mainboard was damaged, so I remove it and tried to solder on another one. That did not turn out too well so i decided to remove the HDMI connector completly and reinstall the mainboard.
Powered on the tv and it worked for minute or two. Then the volume died. I turned off the TV to check my connections and it would not turn back on. I would get 5 blinking lights and when i went to turn it on it would change to 2 blinking lights 5 times.
I decided to order another mainboard. Installed the new main board and when power is applied i get 2 blinking lights 5 times. When i remove the cable that connects the power supply to the mainboard the back lights turn on and the blinking light is off.
Here are my voltages.
MB Connected voltages are at 0 until they jump to proper values for a second
1. B13V———————12.73 to 0
2. PWM_DIM—————3.84 to 0
3. B13V———————12.73 to 0

12. A5V———————5.28 steady
13. B5V———————5.28 to 0
14. Power On_Off——.251 to 0
Big cap voltage———-392.6 to 366

Written on board
A5V:5.3V/18mA
B5V:5.3V/3.4A

Does anyone have any ideas?
