This is the conclusion that I came up with using your (HawwaiianEye & BudM) description. Can you guys verify this please I got 3 of these TV sitting in the closet waiting for repair. Thanks guys.
Just to clarify, the grey with red tracer wire gets cut. I unplugged both thinking that was what you meant by disconnect, nothing happened. After trying a new pwr supply and nothing to loose I cut the wire and it works.
I found the same TV By my Apt. Dumpster. I will go and disconnect the wire as shown in the pictures. I was just wondering does it have any side effects ? i meant Power board getting hot or something else.
This message is for ogad80, budm, and especially my new Hilo friend hawaiianeye. Thanks for helping me fix my RCA for free! On my tv, it was not the red wire, but the gray wire next to it that I disconnected and voila! Aloha from Aiea!
Could it be a mainboard issue with it suddenly jacking the voltage way up and almost forcing the failure of the LED's then cutting that wire locks the output current all the way up, dropping the voltage waaaaay down, causing the LED's to not open up due to the lower voltage which means less heat?
Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.
My computer doubles as a space heater.

Worked for me as well. Not exact model, but damn near close. Massive flickering like a strobe, even power saver mode mentioned on one youtube couldn't save it. Just slowed it down. Cut adj wire and all good. Mine had a 4 pin connector but only 2 wires. One was led off/on other adj. The other 2 pins were off/on as well as adj just not used.. So im assuming the psu is used in multiple sets. I did notice some burning on the psu like it got hot, but tv is running fine. I love this place!
This worked for my tv as well the only side effect I've noticed is that the picture modes don't seem to do much anymore on mine after disconnecting the wire. I also have the 4 pin plug with two adjust and two on/off when I have time I'm going to trying hooking the wire up to the other adj pin and see if that works. I didn't cut the wire either you just pry up the little piece on the plug and slide the wire out
This worked for me after spending money needlessly on a new power supply. Thanks for the info. I would be interested to see if jb14813 's idea of using the other adj pin works.
Just a heads up. This will get the set working but its not a fix. Sooner or later more led's are going to go bad. I've seen several tv's that were close to catching fire from led failures.
Would that wire trick work for me as well, and which wires would I cut...pictures attached.i tried the bottom two on the tip right connector and that wasn't right.
