'''Jeffrey I''' the thing with Samsung is that they really do not use blink codes. Yes, they do show up but there is no good guide for it. The main question is always how to distinguish if the problem is caused by Main board or T-Con. a. No Video : If the problem is No Video but BLU is on and Indication LED is blinking repeatedly and faster than normal booting, replace the T-Con board.
“Disconnected the power board from the mainboard, backlight did not come on” sounds like a power board issue. Check pin 14 on CNM803 on the power board and see if you have 5V on that. If no it’s your power board. If yes check the mainboard power IC output
L202 : B3.3V
L203 : B1.2V
L204 : B1.1V
L201 : B1.5V
IC203 : 3.3V
IC208 : 3.3V
If you do not have that voltage, its your main board. If you do check power on T-con Board.
- L9(T-CON) : VCC12
- TP_VCC33 : VCC33
change the t-con board. If that does not work, you are looking at possibly a failed backlight array.
Let us know what you get. Also, post some good images of your boards with your question. That way we can see what you see. Use this guide 在已经存在的问题里加入图片 for that.
++'''Jeffrey I'''++ for the T-con board follow this one
TP VCC should be marked on the board.

KALVIN MOSLEY yours is a plasma TV so your issues should be different. You need to give us more information about what it is that your TV is doing (or not doing)

Oh, Jeffrey I, Samsung UA46D6000 is just as bad. Chances are it will also damage the LED. Thank you.
