Frequently Asked Questions - 21AB3556 PHILIPS
How can I connect a DVD player to my Philips 21AB3556?
Use a SCART cable to connect the DVD player's SCART output to the TV's SCART input. If the DVD player has composite output, use an RCA cable to the yellow/red/white input (if available) or via a SCART adapter. Select the correct AV input using the AV button on the remote.
Can I use this TV as a computer monitor?
The Philips 21AB3556 has a standard definition CRT with 4:3 aspect ratio and no VGA input. It may accept a 640x480 signal via SCART if you have a suitable converter, but text will be blurry. It is not recommended for computer use.
How do I clean the screen and cabinet?
Unplug the TV and use a soft, dry microfiber cloth to gently wipe the screen. For the cabinet, you can use a slightly damp cloth, but never let water drip inside. Avoid ammonia-based cleaners as they damage the screen coating.
The TV has no picture but sound works. What should I check?
Check that the input source is correct (AV vs TV). If on TV, verify the antenna is connected and channels are tuned. A blank screen with sound could also indicate a poor connection or a faulty flyback transformer. If adjusting settings doesn't help, the TV may need professional servicing.
How to set up or retune all channels?
Use the remote control to press the Menu button, navigate to 'Setup' or 'Installation', select 'Automatic Scan' or 'Auto Tune'. The TV will search for available channels and store them. Make sure the antenna is properly connected.
Why is the remote control not working? How to fix it?
First, check batteries and replace if needed. Also check for obstructions between remote and sensor. Clean the remote's IR lens and the TV sensor. If still not working, test the remote with a phone camera: point the remote at the camera; if you see an IR flash when pressing buttons, the TV sensor might be broken. Otherwise, the remote may need replacement.
How can I improve the sound quality?
The TV has built-in stereo speakers with 5W each. You can adjust bass/treble via the audio menu. For better sound, connect external speakers via the headphone jack or audio output if available.
Is it possible to connect headphones?
Yes, the TV has a 3.5mm headphone jack. Insert your headphones; the internal speakers will be muted. Adjust volume to a comfortable level.
How to use teletext?
Press the Text button on the remote. Use colored buttons for fast access to page groups, and numeric digits for a specific page. 'Reveal' shows hidden answers. Press 'Mix' to overlay text on TV.
Does this TV need a digital set-top box?
Yes, because it only has an analog tuner (PAL/SECAM). In many countries, analog broadcasting has been discontinued. Connect a digital set-top box to the SCART input and switch the TV to AV mode.
