Screen goes black after LG logo

Hi Guys,

I’ve got problem with my LG TV. Since yesterday when I turn on my TV I can see LG logo which disappear after a second.

Sound is working but my TV stays black without screen.

I’ll be honest with you guys I’m not really good electrician so if anyone got some help or tips just keep it simple please.

Thank you very much

Its basically just flash for a second. However after couple seconds when it connect to PS I can hear sounds but I can see only black screen.

appears to be a backlight or power board issue. Remove the back from you rTV and take a look at the boards. you need to find a multimeter so we can possibly check the outputs.

we would need a complete model number for more information. While your TV is dark but you are having sound, shine a flashlight at an angle against the screen (room darkened) see if you can make out silhouettes etc. LG has an issue with bad backlight arrays.
