So my neighbors Samsung UN40H5003 40-Inch 1080p LED TV (2014 Model) decided to stop working in the last day or so and as part of the diagnostics I determined that there was a problem inside the TV. This video runs through opening up the TV and determining that at a minimum there is a problem with one of the LED strips, as two of the LED's are burned out and quite a few had the plastic diffuser fall off which is not ideal and they were banging around and knocking others off.
I checked after I recorded the video and the replacement LED strips were only around $27 USD, so I ordered a set and will see if I can replace that and get the TV working again...and if not, it only cost me the price of three overpriced movie tickets if it fails. If nothing else I get some experience playing with electronics...which is an area I have not done much of in the past other than the basics.
