Re: Rca led50b45rq



I hope my reply wasn't too late, this is a great TV to be lost to a landfill. It's an easy fix with a 50 cent or less SMD LED. The whole LED strip on Ebay is around $15.00. Like everyone else here I always look for dim or dead LED's on the strip, This is not the case on this TV, the slightest amp rise on just a single LED cause's the main board to shut down. The way the LED strips are connected, if one led goes bad on a strip, the whole bank on that side shuts down. This makes it a "swap and try" method just to find the bad LED....

I forgot to add, this is the easiest LED TV to work on I have ever seen. Just remove the screws on the outside back all the way around. Then remove the screws from the T-Con/LCD connectors lift the back. The LCD panel is in the front case.

Re: Rca led50b45rq

This is an old post, but I have found the fault of the RCA LED50B45RQ The fault is, if just one LED is shorted it will send a shorted shutdown signal to the main board to power down. I have never seen an led TV shutdown with just a 3.8 volt drop, I believe it is the amp rise that causes the fault. To find the ( maybe just one) LED, swap the known good strips (left or right side) that light even just a second before power shutdown, with the side that is unlit. when you move the bad strip to the side that lights it will fault. To find the bad LED use a 3 volt dc...
