There could be several reasons why your TV is still not working correctly after replacing the caps. Here are some things you could try:
- Check the connections: Make sure that all the cables and connections are secure and properly connected. This includes the power cord, HDMI cables, and any other cables that may be connected to the TV.
- Check for any visible damage: Look for any visible damage to the TV, such as cracks or scratches on the screen or physical damage to the body of the TV. If you find any damage, it could be the cause of the issue.
- Check the TV's settings: Make sure that the TV is set to the correct input source and that the volume is not muted or turned down too low.
- Check for updates: If your TV has an internet connection, try checking for any available firmware updates that may resolve the issue.
If none of these steps help, it may be necessary to seek the assistance of a professional repair service. It's possible that there is an issue with the TV's internal components that requires further diagnosis and repair.
