When you write 'tuner,' do you mean the internal TV tuner or do you have a cable box between the wall connector and your set's input?
If you are connected from the wall to the set, then the sensitive circuitry (it may only tolerate a few volts max video) is damaged.
If your set was a couple of decades old, it might be fairly easy to repair.
If the set was damaged via the cable service, you may have some recourse unless your cable provider has seen fit to absolve themselves from liability, I suspect they have.
I do not know your set but it is not impossible that the video input circuitry for cable and antenna is on a smaller assembly that processes it before reaching the main board.
The latter has obviously survived since you still have the other functions.

If an LCD TV has sound but no picture do the following:
Use the source button to ensure that source is not set to the wrong input.
Try unplugging power cord for ten minutes, to ensure it is not a setting problem.
Check all the video cables at the back of TV.
Check Light /Color settings.
If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.
If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:
The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.
The inverter must be tested by reading voltages with a multimeter.
The LCD ribbon cable/LCD display and connectors.
This is quite uncommon, but happens. If the TV had been hit or moved the LCD cable may have slipped out, or the LCD connector may be damaged.
The LCD controller board.
This is the board that controls the video signal, it is difficult to test, as there is need to read determined values on IC pins. To test this board you need to purchase a service manual and follow the troubleshooting diagrams on service manual.
Input/Output Signal boards.
This are the boards where you connect the video and audio cables, if a signal board is defective, then you may get no picture on particular inputs located on faulty board.
If under warranty contact the manufacturer ringing the number on the user manual.
If you want to repair at your own expenses, just locate any good qualified repairer.

Since your TV only has audio and video input jacks, you can connect those to audio and video output jacks on the VCR. Now connect the coax cable to the RF/ant input on the VCR and you'll have to change channels by using the VCR channel selector.
Let me know if you require further assistance.
