Hello , my name is Jack
Perhaps I can help you with this problem but first i would have a few questions;

 

Did the tv quit while watching it or just would not turn on today ?

While the light is blinking at the front , could you check if it has a pattern like 2 slow blink -5 fast blinks and repeats etc. ?

Customer: replied 7 months ago.
Quit last night while I was watching it.
Yes, one fast blink and one slow blink.
Expert:  Jack replied 7 months ago.

Thanks , be right back.

By the way , this tv is not very old but may be out of warranty.

Do you happen to have an extended warranty on it ?

Customer: replied 7 months ago.
No extended warranty
Expert:  Jack replied 7 months ago.
No problem , could you give me a few minutes on this ?
Customer: replied 7 months ago.
Ok
Expert:  Jack replied 7 months ago.

Sorry it took a while ,thanks for waiting.

 

The manual is somewhat cryptic on this error code as it indicates a "lamp error code" , meaning the LED backlighting.

 

This in turn points to a defective power/inverter board part # RUNTKA684WJQZ , but then again the error code is not always an exact diagnostic and often just points in the direction where you would start troubleshooting.

 

You could try to replace that board yourself and there is a very good chance that it would clear the problem but without being there with tools and meters myself, it would be difficult to confirm that.

 

Not sure if you had an idea about looking into repairing this yourself but if you do then you could get that board at the link below;

If not then I would recommend a sharp ASC (authorized service center) , you can find the nearest one at the link below;

Just enter your model and zip code.

 

Wish i had better news and an easier solution for you today but i hope this help and I will be in standby if you have any questions.
