TV fell off the table onto its face!
Now the menus display properly and seem to work, but they are on a black background -- none of the inputs generate a picture. No sound either.
I haven't found any loose parts or wires inside. Any idea how I could isolate the problem?

Re: Menus but no Input
Have you checked what Tekwiz suggested? And if so, found anything?
I'd suggest looking at where each of the input jacks meets the board they are mounted on. I assume there were cables connected to these, and that they received a good tug when the TV fell. If that is the case, it's possible the connection between the jacks themselves and the board they are on was cracked or severed. If they look good, check the rest of that board carefully. Since you're obviously getting no input from any port, and since, assuming there were cables plugged in, that board probably underwent the most stress, I would say it's likely the culprit.

Re: Menus but no Input
A careful visual inspection is the way to start. Examine the circuit board(s) carefully for cracks. This may require removal of the board & a magnifying glass. Inspect the connectors where wires enter the board, & pay careful attention to the areas around heavy components. Any cracks found must be soldered where they cross the copper traces on the board. The green coating (solder mask) must be scraped off prior to soldering. Most likely the damage is confined to board cracks, as most solid state components are pretty rugged & not subject to impact damage. Use extreme caution around the high voltage area, as the set may retain high voltage even when off & unplugged. The high voltage area is that around the thick wire that goes to the suction cup on the picture tube itself. If you are not comfortable doing on-board repairs, call a qualified technician to do the repairs.

How do you have your DVD player hooked up to your TV(i.e. composite, s-video, component)? Some DVD payers and TVs have menus to switch inputs and if you somehow switched off the input your players are connected to, you'll get a "no signal" message.
First try hitting the input button on your TV or the Input/connection option in your TV's menu.
If that doesn't work try hooking up the DVD player(s) with the composite Cable(yellow), the component(red,green,blue) and S-Video(black/round) at the same time. If you scroll through your TV's inputs you should get a picture on one of these connections and the TV should display which one. The display will usually be in the corner of the screen.
Might be a resolution issue, the menus are most likely in 480, while the video might be in a resolution not supported by your tv. Try changing the resolution and see what happens.
Are the settings on your tv set to mono by any chance? This sounds like the speaker output is not properly configured. Is this issue only persistent while watching cable? Have you had any issues with DVDs, blu-rays or Netflix? If so you can try doing a hard reset, unplug the tv from the socket and leave it unplugged for 15mins.
