How to find out the series number and model code of a Samsung Smart TV

If you want to turn off the musical that plays when you switch on your HARWA 32 inch Smart TV, you can follow these steps:
1. Turn on the TV and wait for the musical to start playing.
2. Press the "Menu" button on your remote control.
3. Navigate to the "Settings" menu using the arrow keys on your remote.
4. Select "Audio" or "Sound" from the menu options.
5. Look for an option called "Startup Sound" or "Power On Sound." It may be set to "On" by default.
6. Use the arrow keys to select the "Off" option.
7. Press "OK" or "Enter" on your remote to save the changes.
The process may vary slightly depending on your specific model of HARWA TV, but these steps should help you turn off the musical startup sound. If you can't find the option in the settings menu, you may need to consult the TV's user manual or contact HARWA customer support for further assistance.

Samsung Smart TV hidden secret menu allows you to do a factory reset and also connect some Bluetooth devices which you were unable to do before. Be careful while fiddling with these options as I cannot take any guarantee if you spoil the TV settings. The Samsung Smart TV I used in the video is Samsung F4500. The secret menu will not open with a smart remote. You may buy or borrow the original normal rectangular Samsung remote to access the secret menu but I am not so sure that will work.
Here are all methods to access the secret menu of different Samsung smart TV:
Method 1

Put the TV on standby and then push in series these buttons on the remote: 'info, menu, mute, power' the TV will then turn itself on and display a menu.
Method 2

Turn the power off. On the remote, press Mute followed by 1, 8, 2, Power in sequence.
Method 3

With the TV in standby, press the {DISPLAY} {P.STD} {MUTE} {POWER} on the remote.
Method 4

With the TV in standby, press the {SLEEP} {P.STD} {MUTE} {POWER} on the remote.
Method 5

With the TV in standby, press the {DISPLAY} {MENU} {MUTE} {POWER} on the remote.
Method 6

With the TV on standby. On the remote, press Mute followed by 1, 1, 9, Enter in sequence.
Method 7 for Smart TV RU7100, NU7090 Series 7 (suggested by viewer Caleb Harch)
