If the set when first turned on has noise lines or distortion (left to right usually) but after several minutes they diminish and go away you have a bad HYPER board.If this is the case let me know and I will advise you on options.

Please replace the battery with new one. If still problem replace the LED IR in your remote..

I had the same problem and called sears they only chare $99 to come out free estimate. it was a circuit board had to be resoldered and it works great

these sets use a magnetic relay to turn on after a while the metal contact pads on the switch burn (just like turn signal flashers in a car)
this causes the relay to click closed but open up again before the TV can start. the relay is on the power supply board it should be labeled RL1 on the board, it is a small black or, brown plastic cube usually located next to the power cord. If all fuses are good this is the problem.
unsolder and, replace the relay.

Hello,

your TV is having a power problem. Its receiving power but it cannot transfer the current to the necessary part because a capacitor, diode, etc but have been faulty. Until these bad components are replaced, the TV might not come on.

If you know about TV repairers, I would suggest that you open the TV and read the power part/panel with a meter, detect the bad component and replace it. Take note that TV stores a lot of current that can shock, so leave the TV for a while before you open it.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you.

I wish you good luck.

Hello,

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.
