20 Most Recent LG 42LC3R 42 in. LCD TV Questions & Answers

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

the LCD screen has a light source (like a monitor). It can be an lamp (like a projector TV), a mercury tube (like a monitor) or a LED-based lamp (so-called LED TVs have that, not to be mistaken for OLED TVs, where each pixel is a LED). I don't believe this model is an OLED. It could be one of the others, most likely a mercury lamp that lays at one side of the monitor and illuminates the screen. You could shile a flashlight to the screen (from close distance) while the TV is powered on and see if any image is being formed on the LCD. If it does, the lamp is burned out and needs replacing. If no ghostly image is seen, then it could be the video processor and then it's a bigger problem.

LG Zenith recommends replacing the Y-sustain, x-sustain and digital /logic board as a set. After you replace you will need to check the voltages listed on your panel. The cost if bought from second hand dealer like shopjimmy.com will be around 250-300 for the parts.

Clean the Lens: Use a DVD cleaning disc to clean the lens. If the problem persists, consider professional cleaning. Test Other Discs: Try playing different DVDs to see if the issue occurs consistently. If it's specific to one disc, that disc might be the problem. Check for Updates: Make sure your DVD player's firmware is updated. Refer to the manufacturer's instructions for firmware updates. Try a Different TV: Connect your DVD player to a different TV to see if the noise disappears. If it does, the issue might be with your TV. The hum is simply the player trying to read the disc. It can't so, it spits it out. Remember that prolonged use of a malfunctioning DVD player could potentially cause damage. If the problem persists, consider seeking professional repair or replacement

Maybe the disk is not compatible with the DVD player version

It can't be done. The DVD remote will be single frequency for that device only and the LG remote for that LG Blu Ray (or series) only. Companies don't make cross-control between makers easy.
