Look at one of the power supply output connector pin, there should be 5vdc all the time the minute you plug the TV into the wall outlet, if you do not have the standby 5vdc, nothing else will work. No sign of burnt parts, bad capacitors? You can get parts here: http://www.shopjimmy.com/catalogsearch/result/index/?q=Toshiba+37HL67+&p=2&stock=all
Please post feedback what you find.

This problem is caused by at lease one of three conditions;
1) The inverter board(s) is bad.
2) The power supply for the inverter board is bad.
3) You have bad CCFT(s) (Cold Cathode Florescent Light)
do you have the satellite hooked up through the coax cable if so that could be the problem you will have to manually set the settings with the remote. always make sure you have only one thing hooked up at a time. if you have cable and satellite dont hook up both it makes the picture lousy see the owners manual i think its page 58 or somewhere close to there.some times if both are hooked up it will not work at all.
if it is an new 360 arcade, pro or elite with an hdmi output on the back, buy a hdmi cable. if there is no hdmi output on the back like most original 360's, buy the official 360 vga cable and conneect it to your pc input. this will ensure best quality, last resort is YcPcb
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.
