Hello
Power supply board has damaged. it must be checked well for faulty components. We cannot predict the fault due to lightning. It will be best to replace the power regulator board rather than making surgery with it now in this condition.. OK.
I have over 10 years experience in electronic tech support.
I
know this isn't what you want to hear, but the problem you've described
can't be fixed with troubleshooting. Your TV will have to be repaired.
There is a part that has developed a defect and needs to be replaced. If
you're still in warranty, the TV will be repaired at no charge to you.
The warranty would likely be at least one year from the date of
purchase from the manufacturer. If you purchased an extended service
plan they will repair the TV at no charge as well.
If
the TV is no longer in warranty, it will likely cost a minimum of $150
parts and labor. This is assuming that you only need a power supply
module. If the problem is more than one of the circuit boards, the price of
repair could go much higher.
I hope I've provided you useful assistance and that this information
allows you to make an informed decision as to how to proceed from here.
Please be sure to vote on my response. I hope I've earned a good rating from you today.
Please let me know if I can be of further assistance.
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.

There may be loose contact or track open in main board.So try to check the main board thoroughly where you may find the loose of connection or track open.
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.
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.
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.
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.
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.
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.
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.
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.

They are purely a numerical identifier of when it was made, year, day, number on the shift, whether it Joe or Billy who did final inspection.
With a MODEL number I can find them easily with just 'make model manual'.

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.
Same issue here. I kept plugging in the TV and it would flash the logo and go black. I disconnected the LED line from the power board, plugged the TV back in and the LED's all lite up and got great picture. Turned it off and on a few times with the power switch with no problem. Left it alone about an hour, came back, got the same symptoms all over again, Flash then nothing.
I changed out the Power Supply board....same issue, Flash of logo and black screen. Probably going to heave ho the set.
