iPod touch 5th generation in a wierd boot loop

I recently found my ipod touch 5th generation back (the battery got replaced 1,5 years ago and i lost it). I plugged it in to a charger and it is stuck in a boot loop but the apple logo doesn’t stay there it goes away after about 5 seconds. I tried plugging it in my computer but nothing happened the screen didn’t turn on and itunes didn’t recognize it. And it also doesn’t turn on without a charger. I tried putting it in recovery mode wile plugged in in a charger, it worked but the screen turned off again after about 2 seconds and now I can’t get it in recovery mode again. Can someone help me get it in recovery mode and recognised by itunes.
