There may or may not be a compatible controller board. There are 3rd party display interface to HDMI boards available for LVDS type screens found in many old laptops and VGA monitors. Get the model number from the back of the screen and search Ebay.
If you are having graphical issues such as a burnt out CFL back-light tube then of course you will have to fix that beforehand. There are kits for that as well....... either CFL replacements or upgrade to LED back-light.
IMO for the cost of all that you could buy a brand new HDMI TV.
Unless specified otherwise my response is based on the latest and fully updated RPiOS Buster w/ Desktop OS.
