I have an old magnavox model number 22787047 that only gets static. Is there a fix for this? Thank you.

If this is an older CRT TV, you probably have no analog TV signal present - most nations have converted to digital TV. In that case, the only way it will work is to get a digital to analog TV adapter box to connect to the antenna or video input terminal.

If it's an AM/FM radio, the bandswitch may have dirty or tarnished contacts. This can usually be fixed by opening the radio and spraying a bit of electrical contact cleaner into the switch (it does not work to spray it on the knob shaft or switch actuator from the outside of the radio; you have to get directly on the contacts inside the switch). The volume control may also be dirty; use cleaner made for electronic volume controls, rheostats or potentiometers. Do not use WD-40 or other solvents; they may dissolve the resistive material and ruin the part.

While you have the radio open, check the AM antenna coil (a black rod or bar about 2-5 inches long with wire wrapped around it. If the black ferrite material is cracked or broken, the antenna will be much less effective, if it works at all. If this is replaced, the AM input transformer will probably have to be retuned for optimum performance. This should be done only with a plastic screwdriver, (metal messes up the tuning and may break the ferrite transformer core). This is best done using a post marker-sweep generator and an oscilloscope.
