rear projection tvs are always an "easy fix" lol, never come across one that wasn't, look up the symptoms if you can online and get some insight, sometimes they're easy to fix but hard to find the part or not worth the repair cost.
its not something i would get into, in addition to the broken part, it could need a cleaning, and alignment, although doesn't seem too bad from the crappy pictures.
Remember its 75 bucks to pick it up, plus repair costs, and if it doesn't fix it, disposal/recycling costs also.
I looked up that flywheel thing they talked about in the 2nd link , its 80 bucks and some soldering on a quick google search from what I could tell, but there are all kinds of voltage regulators etc inside of those things... so who knows for sure
Could be worth it if you're willing to spend time and a bit of money on it, but remember those are dated tech now...
