How to bypass error code?

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!

The #8 wire plug is easily removed from the harness by carefully prying up its tiny anchor tab. It can then be re-inserted in hole #24 which is a ground. Works like a charm! I adjusted the brightness down to 50% as some others have suggested -- I also see a couple of dimmer spots along the bottom edge of the display. I have ordered LED backlight strips from ebay (supposed to be compatible) for under 30 bucks. This YT video shows how their replacement is done on the XBR-55X800E: https://www.youtube.com/watch?v=0RKf8Hio... I'll have to work up the courage to DIY.

Thank you for this Q and A -- I'm so glad I was able to find it!!

@mikeroesler hope it works out for you. Only word of caution is about the LED strips. I have not been impressed with the ones I got of eBay. They were inexpensive but have had a difference in brightness. It may just have been that particular seller but it got me to stay away from ebay. Hopfully yours is a good experience. Let us know how it all turns out.
