SOURCE: How do i fix my lg47la6400 smart tv when i switch on only logo of lg in the screen cannot select desired inpu

Do a hard reset to this set, and then check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

SOURCE: Have a LG Tv that has sound but no backlight, can see image with flashlight. When you first power on TV show white screen with LG logo then goes black. Tv is a 55LN5790-ULBUSULJR

Well, you've done the easy part. The unit has sound and picture, but no backlight. The next part is tedious and delicate: dismantle the unit and find the cause. Many times, the problem is cabling or wiring, but once in a while the problem is control related. if the unit is under warranty, have it serviced by an authorized service dealer. If not, it's up to you. The new, flat tv's are super easy to wreck once the case comes off, so unless you really know what you're doing, it is very easy to justify paying a competent professional to repair the unit.

Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

My 55inch LG 3D smart tv is not working properly. When you turn the tv on the LG home screen comes on for a few seconds, and then the screen goes black. What is causing this


it's set to the wrong input device ? the one you currently have it pointed to has no input

also it's possible that cable plugged into current input channel has gone bad or become disconnected from it's source
Hdmi cables are unfortunately famous for this as they have no Lock device to keep them inserted into ports

most TV's nowdays shut off if not provided an input for a few minutes

No picture but lg logo comes on 55" smart tv. Ic there ssomething I can check for at home?


If you paid for it with a credit card you usually get an extra year on the warranty from the car.
That said did someone accidentally change the input from the menu , usually if you get a logo then the pic is still working

Hello, I have a lg lcd monitor. w1941s model. when I start my computer, it work for sometime. then it goes blank showing only the LG logo. then the power button doesnot work. it hang up glowing. again


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.
