JVC AV-27CM3, not working after transporting home

[CRTguy]

I recently bought a 27" JVC CRT from 1992 (Model AV-27CM3). At the seller's house, the TV turned out without issue and the picture looked good. I then transported the TV in my vehicle to my house 2 hours away. I transported the TV screen side down in the back of my SUV. I didn't hit any major bumps while traveling. As soon as I got home, I carried the TV in my house, plugged it in and now it doesn't turn on. When plugged in, there is a red standby light that turns on and is constantly lit. Pressing the power button doesn't make the light flash/blink or turn the screen on. I have taken the boards out of the TV and I don't see any blown capacitors or bad solder joints. I also reconnected everything after inspecting the boards and it still doesn't turn on.

What is mostly likely the issue? Could this simply be a weak capacitor in the power supply causing the TV to not be able to start. Could bad solder joints cause the TV to not turn on. The previous owner told me that the TV wasn't used much. The inside of the TV is clean and there aren't any dark marks on the circuit board that you commonly see from a CRT that was moderately to heavily used.
