[Philips, Sony, TCL Android TV] BertProesmans:
My parents have a Philips 48PFK5500/12 Android TV, and asked me for help with this issue. I can confirm the above steps worked for binding a new account login to the television.

IMPORTANT; Log in and open the Play Store app to accept the Terms of Service agreements. Then give the television (a lot of) time to update all pre-installed apps!

Because this is about older televisions and compatibility things I'm going to explain the steps at a very basic level.

Steps I used (menu titles translated from Dutch so your titles may vary);

ON TV

1. Settings > Android settings > Security > Unknown sources - set to enable

2. Settings > Android settings > About > Build - Press OK 7 times

-- You have now enabled a special developer menu, but you need to reload the android settings screen to see it

3. Press home

4. Settings > Android settings > Developer options (last button in section Preferences)

-- Developer options > Debugging > USB-debugging - set to enabled (should be already enabled by default)

5. Settings > Wireless and networks > With cable or WIFI > View network settings, get the IP-address of your TV

ON COMPUTER - Preparation

1. Download and unpack ADB platform tools

-- See https://developer.android.com/studio/releases/platform-tools

2. Download Google Play Services from APK mirror, I used version 22.45.16 for armeabi-v7a

-- See https://www.apkmirror.com/apk/googl...le-play-services-android-tv-22-45-16-release/

ON COMPUTER - Make a connection between your computer and TV, using adb.exe

1. Open terminal in de platform tools folder

2. Connect with ADB to the television, execute command adb.exe connect 192.168.88.45

-- My TV has IP address 192.168.88.45, replace this by the IP of YOUR TV

3. ON TV; Accept the popup asking to connect to your pc

ON COMPUTER - Fix TV login isues

4. Install the downloaded Google Play Services APK, execute adb.exe install -r "C:\Users\Bert\Downloads\play services update-1.apk"

-- I renamed the downloaded APK file on my computer, replace with your own file location path

5. Wait, my install took 230 seconds

6. Reboot your TV, execute adb.exe reboot

ON COMPUTER - Preparation

1. Go to https://myaccount.google.com/apppasswords

2. Setup an app-password for your account

-- APP passwords are special codes of 16 characters, like "adym tjje eeae heur"

-- When you type in APP passwords, don't type the spaces

ON TV - LOGIN

1. Settings > Android settings > Add Account

2. Add e-mail address, type bertproesmans@gmail.com

-- Replace with your own e-mail address

3. Add your APP password, type adymtjjeeeaeheur

-- Replace with your own app password

The login process will now display a message indicating Success!

ON TV - Further updates

1. Open the Google Play Store app, Home > Google Play Butik

-- Not sure what the difference is between "Google Play" and "Google Play Butik"

2. Accept the ToS

3. Google Play crashes, press OK to close

On this TV, all preinstalled apps started updating. This procedure is recognizable by the message "repairing app.." on the home screen tile(s).
