Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems. I'm reviewing your details now and will reply shortly.

The 1 short followed one long blink code on this set, indicates a failure of the LED light strips within the LCD panel (code translates to: "Lamp Failure")- which is also shown by the screen displaying images with no backlight). That said, in order to repair this set, the LED strips would need to be replaced. If you're looking to repair this yourself, the LED strips can be purchased at the link below for your model:

Additionally, there are videos on Youtube that outline how to perform this repair yourself. Otherwise a shop charge would be quite expensive- starting around $350 for this type of repair. However if you're not looking to work on the TV, then you can use the link below to locate a shop in your area if you'd like:

There aren't any pushbutton fixes for that code- if you're saying the screen will not backlight, and the code is 1 short and one long blink (or vise versa), and it does indicate the LED "lamps" on the screen have failed. Let me know if you need further help.

I have a LED Backlight Tester and I have tested all the 15 Rows of backlight with it and all have tested ok with a reading of 147 VDC and 29.1 ma .I have already purchased two complete rows of new LED with the same part numbers as row 1 and 2 which is repeated to the fifteenth row in the TV but I have not installed it because when assembled and tested they are reading the same 147vdc and 29.1 Ma.

I need some help? I am getting an error voltage of 3.31 Volts on pin 22 of Connector PD that is going to the Main Board .
Customer: replied 1 month ago.
Is there any way to switch on the lights? I am presently getting 127 Volts at the Anode of the first LED Diode in each Row which have 30 in series and all the Cathodes are each connected to the Collector of 15 Transistors and all the Emitters are at ground potential..I know the circuit is monitoring the current but I got the same current of 29.1 Ma with the LED tester at 147 Volts DC.
