It could be the charger itself. Other than that, you could try seeing if the port on the SP itself is clean, there could be an accumulation of dust/lint. I think it could be the charger itself though since it's loose.

The LCD is what broke I guess, not the digitizer right? You could try to order a new one and fix it yourself or see if you can send it in to someone to fix it. This is not really a question.

I don't know how batteries work over there in Romania but you might have used unsuitable batteries. Sometimes there's batteries that will still fit but may have more power, thus, causing an overvoltage of some sort and overheating. If you used good, suitable batteries, then it could just be a defective unit. I would look and see if other people are reporting the same problem.

I'm not an expert on TVs but I can suggest looking at your brightness and contrast settings of course, but also any power-saving settings. Often times, there can be an option to save power by using less of it resulting in a dimmer image. If none of that works, then a reset could fix it. Try a soft reset if there's an option and then a hard reset if there's a button somewhere. If not, just unplug the unit and let it sit for a bit, plug it back in and see if it works...

You could try to put all the music into the SD card itself to see if it's the culprit. I would never trust an SD card off ebay. I believe there's ways to trick people into thinking they're buying a high capacity drive for instance, 128GB, however, in reality, the card may only have 32, 16, or 8GB even though the computer may say it's 128. I saw a video on a fake USB drive on YouTube that showed the USB as having so many GBs of memory when it only had a few. If you have a spare SD card, try that.

There is a guy that sells boards for use with microSD cards, SDXC, CF, and mSATA storage. I suggest checking out http://iflash.xyz . To better explain, yes, you can put a 1TB mSATA SSD with the appropriate board, however, most recommend also replacing the original battery with a larger capacity battery if you're planning on using an mSATA. If you don't want to replace the battery, you can go with SDXC cards. They tend to come in capacities of 128GB, 256GB, and some in 512GB. They will use much less battery than the mSATA SSDs and I would like to some day upgrade my iPod with a couple of 128GB SDXCs. I recommend staying away from CompactFlash since they're pretty dated and come in limited capacities (I've seen most around 64GB). As I said before, you can go with a 1TB mSATA but you'll also need a new battery so that's up to you, you can go with just 1 mSATA or you can buy a quad microSD or Dual SDXC adapter and go with that. Either way, the above website still has plenty of resources and guides with...

Have you verified that the ribbon cable is in the correct position? Sometimes we may confuse the connections and either place the ribbon cable backwards or the HDD itself backwards. I suggest looking at the HDD ribbon cable and the orientation of it and the HDD.
