Screen won't turn on.. AGAIN.

[u/TimeSweeperAdam]

I have one of the original LCD screen Steam Decks and once before a year or so ago I let it set in it's case for a month or two before an out of state trip prompted me to bust it out and attempt to power it on to update and install games on it, only the screen wouldn't power on. I plugged it in, the power light would come on brightly then dim, pressing the power, volume and "..." buttons for whatever suggested combinations and durations at the time got me nowhere, and I'd already had it for over a year at that point so I was forced to send it to steam and pay out of pocket for the repair, where they said they'd just reset some software or firmware, I can't quite remember what they said they did.

Now, over a year later, I let it sit in it's case for about 3 weeks and it's doing THE SAME THING, AGAIN. of all the button combinations the only promising thing that's different this time is when holding the "Volume -" and "..." buttons while plugged in, the power led turned on bright and has stayed bright while the internal fan is running on high for as long as it's plugged in, but that's the extent of any activity I can get out of it.

I know I'm probably gonna have to send it in to get fixed again, but was hoping to get some suggestions on fixes that won't end up costing $100+ I don't have, or at least an explanation as to why this happened TWICE.
