How to bypass error code?

Block Image

Block Image

Which pin do I disconnect and ground to bypass six red blinking lights? Board number APDP-209A1 (Brown board). On the board there is the word "Secondary" with an arrow pointing; (CN6401-8) BL_ERR.

I assume this is the pin I want to disconnect and ground. Do I count from the top? Does secondary mean it's on the bottom and not the top of the plug since there are two wires for each position?

I removed the eighth pin counting from the top down on the upper row and it prevented my TV from powering on.

@erlonbailey remember that disabling the error code signal is not a repair. It may, or may not turn on and it may, or may not fail completely.

Thanks! I figured it out by continuing to test each possible connection. You are exactly right, it was the fourth black wire down from the top on the upper side of the connector. The TV is working great now and has not shut off yet. Fingers crossed! One thing I noticed after getting the TV to work is very small area in the lower right portion of the screen that is slightly darker. Further, I was able to get into settings menu now and turn down the brightness level in hopes of preserving the TV as long as possible.

@erlonbailey AWESOME! I bet this"very small area in the lower right portion" is a bad LED :-) Crazy right? One itty, bitty LED and BOOM, disabled. I wonder how many people, that do not come here for help, end up buying new. What a waste of resources and hard earned money!

Pin #2 pulled out and moved to slot #4 ground. The YT video provides the explanation. This was our setup not exactly as the video.

From this YT solution as a reference https://youtu.be/T3VRvQUB_DQ?si=jXIjIRpj...

we temporarily fix the 4 flashing red light for sony KDL-70W840B. We'll just wait until the TV gives out. For now it works.

followed the BL_ERR as per yt video, our tv is a different model.

Thought to share this temporary fix for this particular sony model. Hope this helps.
