Make sure the yellow permanent power wire is connected to a constant 12 volt source otherwise it will reset every time the unit is turned off. If the permanent power yellow is connected, there is a hardware fault in your head unit and will either need to be repaired or replaced. Also ensure the chassis of your head unit has a solid ground and the black negative wire is securely grounded. If you are able to tune it while it's turned on it means the control panel is functioning properly (sometimes the control panel contacts get dirty and prevent the unit controls from working properly)
The Sony remote may be working fine. You may have to test it on another Sony TV such as at Best Buy or at a friend's place. Some of the Sony TV's had a bad or defective infrared(IR) board. If the IR board fails, then the TV will not respond to the remote. The TV will work fine with the manual controls, but will not respond to the remote. If you are handy with taking apart computers, then taking out the IR board is not that hard. It looks like a computer memory or RAM board. One can buy a replacement board on the internet or send your bad IR board in for repair. I did just that last week by sending it to a repair service. I got the board back in less than a week and installed it. The Sony TV works fine with the remote now. I found the repair service on E-Bay. There was one in Indiana and one in California. I used the one in California. It all depends on the Sony model, but there appears to be a bunch of models with a defective IR board. Yes, it was really frustrating.
Check the remote control first. Hide it from the vicinity of the TV and check whether the TVs' panel buttons works properly. If yes, the remote control is faulty. Can't be repaired.
If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one. Gopakumar Gopalan Google
Sounds like the circuit track inside the remote control [at its PCB]; had opened. An open circuit can cause this fault. In most cases, this fault can be repaired. Contact any service technician. The remote control has to be opened.
If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.

Check the remote control for its infrared emission. Check it with fresh batteries. You can check it with the help of a cell phone, having camera option. If there is no infrared emission, replace its infrared LED & oscillator crystal and check. Check this link for more details about how to check and repair a remote control.

If the only thing not reacting is the audio, then the audio board or the main board has gone bad. Enter the model number and tv make on you tube to get more detailed info.
There's clearly a heat-stressed component in there, possibly something as simple as a badly soldered joint in which a gap opens up due to heat expansion.
It's not that old a TV so may be covered under warranty. If not it's going to need to go into a repair centre where they can find the fault and repair or replace the affected part.
Re-soldering a bad joint isn't always possible in which case the circuit board which it's located on gets replaced instead.
