Yes, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:

When was the unit repaired last? If it is doing the same thing and is only 5 years old, it sound like a bigger problem than just what was repaired. I own a 56" projection TV and mine is 6 years old and I have yet to have a problem with it...(I shouldn't have said that...) If I were you, I'd call Toshiba and explain the situation and that it has been repaired once already under warranty. Chances are, they'll be able to help you to your satisfaction. I once purchased a JVC stereo receiver from Circuit City and had to take it in to be repaired 5 times and the warranty had expired after my second trip up there, but they were nice enough to repair it - free of charge - the other 3 times. Toshiba seems to be a company that stands behind their product. Good luck! Hope this was helpful...
You need to replace both convergence ICs they are STK392-110 you can get new replacements at the following link and they provide free instalation instructions with pictures so you can do the repair yourself in about a half an hour.

This is a convergence problem. Try resoldering the pins on the convergence ICs. These are large black ICs attached to a heatsink. They should have about 15 pins and be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs. These should cost about $15-$25 each.

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'.
