Toshiba 32a40. The display on the screen shrinks
You've got at least one board that's gone bad. Were it mine, I'd donate it to a local charity and get a new one. The charities have volunteers and job trainees that do the repairs, and might be able to make a buck on it, while you get a tax write-off.

Toshiba 42RV500E sound issue
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.

Toshiba 47" flatscreen. Power up
The information provided suggests that there might be an issue with the main board of the electronic device. However, it's important to consider a few factors before deciding to replace the main board:
- Check for Error Codes or Diagnostic Signals: Some devices have error codes or diagnostic signals that can provide more specific information about the issue. Check the device's manual or documentation for any error codes or signals associated with the flashing LED or other symptoms.
- Perform a Hard Reset: Before replacing any components, try performing a hard reset on the device. This involves turning off the power, unplugging the device, and waiting for a few minutes before plugging it back in and turning it on. Sometimes, this can resolve temporary glitches.
- Consult Manufacturer Support: Contact the manufacturer's customer support or refer to the product's support resources. They may be able to provide troubleshooting steps specific to your device and guide you on whether a main board replacement is necessary.
- Professional Inspection: If you are not familiar with electronic repairs, consider consulting a professional technician. They can inspect the device, run diagnostics, and provide a more accurate assessment of the issue.
- Check Warranty: If the device is still under warranty, replacing components yourself may void the warranty. Check the warranty terms and conditions before attempting any repairs.
- Consider Other Factors: The issue might not solely be with the main board. Power supply issues, faulty connectors, or other components could contribute to the problem. A thorough inspection can help identify the root cause.
If, after considering these factors, you still believe that the main board is the likely culprit and you are comfortable with the replacement process, you can proceed with replacing it. However, exercising caution and exploring all available troubleshooting options is advisable before making any decisions.
