I have problem with LG TV 42LD550. After power up I see just first screen "Live Good" with no time on it and that all. Remote doesn't work, buttons on TV don't work. What can I do?

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Does this tv need a dongle to connect wireless? Read the specs. You'll need the adapter which is sold seperately.

Lg tv 42ld550 stays on standby and can not be switch on

You will need to have the set diagnosed to find the problem. It could be an issue with the power supply or main board. If you are up to it, take off the back cover of the TV set and take a look at the capacitors on the power supply. If there are any that are bulging, most likely that is your problem.

My tv is on stand by mode and I can not switch it on

First thing that comes to mind is to have the power supply capacitors checked for any bulging. Outside of that, you could have a defective main board or power supply board. Unless you have electronics repair experience, you will need to get the set diagnosed.

I have a LG 42LD 550 just got it, couple day, it began turning itself on & off, the LG start up screen comes on, its not responding to the remote or the switches on the TV, any idea what is the...

Yes its faulty. This is not me being funny. The 42" TV has had many faults and weas under recall. LG does not mean good life. It means lotta garbage. If this is new take it back and have it replaced. Preferbaly with a different brand. If it was second hand it has to have minimum guarantee and be covered up to 7 days for colling off and trial period.

Get it back fast, the repair cost is sky high ( $600)

Please rate my help++++Thanks for using FIXYA

LG 42LD550 LCD - Internet connection problem

After the network is connected to the TV, you have to go into the TV’s network menu to complete the setup process.
If you look in your owner’s manual starting on page #55-#57, you can read the direction to walk you through the wired network setup process.
It should be very easy to setup as long as your router has the DHCP turned on. That allows the TV to automatically assign it an IP address on your network.
If the DHCP is not turned on in your router, then the TV’s IP will have to manually entered by you.
