20 Most Recent Toshiba 20AF43 20" TV Questions & Answers

I am NOT too keen with 'universal remotes' because often the CODES listed are not accurate so your item (in this case a TV) may never respond without the proper code entered... Some remotes offer a FISH method where you manually "step" from one code to the next... no fun but SOMETIMES your TV will suddenly respond again! Now the IR SENSORS are rather rugged and seldom 'burnout'... but the board it mounts on is another story. Your Service Manual can be found at the link below but the print is so tiny I was unable to locate the board with your IR SENSOR quickly... time is a issue and the link is a start! One BAD point is that I found no USED boards for your model on eBay... not good. Anthony Toshiba 20AF43 Service Manual

Greetings!

You have a great little set. These made a great picture. It is impossible to tell without inspecting it myself, but the most common things we found on this era of Toshiba was open flyback transformers and shorted horizontal outputs. Neither of these do I recommend you attempt, because you will be working in the high voltage circuit and can subject your self to unhealthy voltages (in excess of 30,000 volts). Refer this to a qualified technician, but a fair and honest one who will charge you a fee that will make it worth repairing. Make sure he/she checks the socket on the picture tube, too.

Good luck,
Rob

This is a known issue with this TV. The following might resolve it: Check Mute and Volume: Ensure that the TV is not muted and that the volume is set appropriately. Sometimes accidental button presses can lead to muted sound or low volume. Inspect External Speakers: If you're using external speakers, verify their connections. Loose cables or faulty speakers can cause sound issues. Test Different Inputs: Connect a non-HDMI device (such as a DVD player) to the TV. Observe if the sound distortion occurs. If it doesn't, the problem might be related to the HDMI signal from your Virgin box. HDMI Troubleshooting: If the issue persists with the DVD player over HDMI, consider the following: HDMI Cable: Check the HDMI cable for damage or loose connections. Virgin Signal: Contact Virgin to inspect the signal/lines and replace the box if necessary. Mainboard Replacement (if needed): If the sound distortion persists, it could be due to a faulty sound processor chip on the TV's mainboard. In this case, consider replacing the mainboard.

1. Locate the Battery Cover: Look for the battery cover on the back of the remote control. It is usually a small compartment that can be easily opened.
2. Remove the Battery Cover: Depending on the design, there may be a latch, screw, or sliding mechanism to secure the battery cover. Use your fingers or a small screwdriver to open the compartment.
3. Remove Old Batteries: Take out the old batteries from the battery compartment. Pay attention to the orientation of the batteries, so you know how to insert the new ones correctly.
4. Check Battery Polarity: Take note of the positive (+) and negative (-) signs inside the battery compartment. Make sure to insert the new batteries with the correct polarity to match these markings.
5. Insert New Batteries: Place the new batteries into the battery compartment, ensuring they are properly aligned with the correct polarity. Press them down gently to make sure they are secure.
6. Replace Battery Cover: After inserting the new batteries, close the battery compartment cover securely. If it has a latch or screw, make sure it is fastened properly.
7. Test the Remote: Point the remote at the device it controls (such as a Toshiba TV) and test whether it responds to your commands. If the remote is working correctly, you have successfully replaced the batteries.
8. Dispose of Old Batteries: If the old batteries are no longer usable, make sure to dispose of them properly. Many communities have designated recycling locations for batteries.
