Sony 32" Flat CRT from 2003 Goodwill find

[Olorin67]

Just got this from my local Goodwill for $10. Model KV-32HS510 32" HD flat CRT- (4:3 ratio) date of 2003 on the back. It's a heavy beast.. The goal is to replace my 24" Sony Wega I've been using for my main set to watch old movies in the living room.
Had a few questions for people familiar with these. It has a DVI input for HD, so it's my first foray into HD and digital video. Am I limited to blue-ray players that have analog sound outputs? I can get a cable to connect a HDMI source to the DVI port on the TV, but that doesn't handle the audio. I would be using the speakers on the TV for sound, or maybe hooking it into my stereo, but I don't own a receiver with digital sound inputs or surround sound (and probably never will since i'm into vintage tube stereo stuff)

Does anyone know if this has a ATSC tuner in it? or is it analog only? (if not, I have a converter box I can use)

Didn't come with a remote, do I need one specifically for this set, or will most early 2000's Sony remotes work? are there functions/menus that can only be accessed with the remote?

Are there any common issues or failure modes with these I might need to be prepared for?

I don't currently have any HD sources, but I would like to get a Roku or Blue-ray soon so I can get Netflix and watch Dr. Who.
I mostly watch Laserdisc or VHS, some Beta and DVDs also. I don't currently watch any TV or cable, just old movies and such.
