It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
1) you have problem with the Raster 2) the main causes are a) raster b) picture c) sound d) synch3) since this are not video, the problem is raster. your musttest the voltage from section horizontal out +125vdc+vertical output +80v+all other circuit +12vdc4) test the power supply for defective. see the diagram attached
hello, usually if the remot control is ok, then the infrared receptor need to be replaced, he is placed near the stand by light. in a rare case the problem is at the 5v voltage that goes to the receptor. more rare is the possibility that something is wrong at the microprocessor circuit.
i hope it was helpful!! Let me know if you need further guidance
Chassis for your TV was bult in 1998 and put into mass production in the 1999. It was used in various TVs for over 3 years. So when it comes to decision wether to invest or not, first try to identify the problem and to estimete the repair costs.
IF the sound quality is poor on all sources then the issues in the television. possibly old failing components, might require some maintenance / repair.
This site has the TV manual for the model you listed. On pages 12 and 13 sre the instructions for setting up the channels. Paste the above into the address line of your browser. Highlite it and copy and then paste into your browser.
Hi,
I do suggest you completely let the set dry ( say a week or so ) and then retry the set. If at that time the set doesn't work, you'll need to check all the fuses ( glass and ceramic). If they are all good, then it's time to seek professional help, as one of more components may have been damaged. Good luck and I hope this has helped.

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.
