The “data corruption” 3 beep pattern during the power-on self-test means that you (most likely) still have the wrong (or static-electricity damaged!) RAM. Go to crucial.com and find out what the right RAM is.

The TV work-around suggests that the computer has retained the state of “monitor not working” in software (drivers) or firmware (BIOS as backed up by non-volatile RAM). Try resetting the BIOS to default settings, upgrading the drivers, and replacing the button battery that keeps the RAM and real time clock running when the laptop is powered off. https://www.dell.com/support/article/ca/...-to-use-and-troubleshoot-the-inspiron-15-7559-?lang=en

Your description is consistent with a damaged/displaced connector that can no longer seat the cable connector as it is out of position. Try *gently* pulling the connector back towards where it is supposed to be mounted with the thinnest grasping tool you have (e.g. needle tip tweezers). If it reseats with a click, you should be fine, but keep in mind that you now know it’s delicate and can be pushed back in at any time. Good luck.

There’s not much info to go on with your question, but given that the Logitech Review is mentioned… The Review has HDMI and Optical audio outputs. Intermittent audio can be electronics in the Review, bad cable or contacts, or the TV itself. So it’s time to proceed to fault isolation, going from least expensive to most and stopping when the problem resolves Start by reseating the HDMI cable at both ends; check to see if the contacts are dirty. Try a known working HDMI cable; you don’t need anything special or up to date, as the Review is old and therefore doesn’t take advantage of things like networking over HDMI Use another HDMI source (borrow if you don’t have one) to see if it’s the Review. Finally, see if another HDMI TV eliminates the problem. Keep in mind that the Review is old, and Google no longer supports the Google TV software platform. If the Review itself has failed, you can get a refurbished replacement on eBay. If you are feeling ambitious, intermittent failures in audio that are in the Review ar...

I don't have an S4 Mini in front of me...and I hate to ask something obvious, but are the screws all the same length? It's a common enough problem on device re-assembly that it's worth checking.

There's one key piece of information missing: can you replicate the problem with different headphones?

I bought the Seagate 4TB hybrid. I also bought the OWC cable, just in case (I had another use for the Seagate drive if required). The hybrid drive is rocking along very nicely, and now I won't have to replace it again (knock on aluminum!) for the effective lifetime of this machine. Take your time, it's not a hard task. One caveat: on my machine, at least, the plastic lock releases on the display connector on the cable to the graphics card are fragile (hot environment). One broke, but I was able to reseat the connector without difficulty. Very happy with the hybrid drive. Next upgrade is maxing out the RAM.

You open the iTunes app, and then follow the directions here (Apple Support).

Buy or borrow an IDE to USB adapter. An IDE + SATA to USB adapter is a part of my regular 'tool kit' for exactly this reason.

I would suggest that you consider the early 2014 Mac Mini i7, since you don't care about the display. Same compute power with a much smaller size. I use one as a server, and it is excellent.
