LG 42LV4400 42-inch LED TV Questions & Answers
My lg mod# 42LV4400-UA tv will not turn on
LG had a serious quality problem with the main board and there is a bad solder joint on all original 42lv4400 and 47lv4400 units.It will manifest the problem either went it gets warmed up and then power down itself or never power up. The red light stays on and the TV does not respond to manual or Remote input.A factory reset will not fix this problem. It takes a "NEW" main board. The big white label on the back panel has the original manufacture date and LG will send out a factory authorized technician to repair the unit within the first year after that manufacture date.call 800 243 0000 to schedule a home visit to get the repair done.By the Way, a 42lv4400 main board will not work in a 47lv440 even though they look identical. The reverse is also true.
I have a LG dvd

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
