When ONE led on the strip fails, the amount of current being sent through the strip changes. It can cause the unit to sense the change in current and shut down. You can replace all the strips or you can use a meter to check the diodes and see how many failed and then replace those individually or the whole strip they are in

A modern tv is as much computer as tv and so contains much circuitry that is ultra-sensitive to voltage surges and spikes that often accompany power outages or electrical storms (nearby or distant).

Repair costs can sometimes be met by the power company or your domestic insurer...

Usually the flashing red light would be transmitting a blink code that would at least provide a strong clue to the nature/location of the fault.

The symptom you report seems to be fairly common and a quick search produced others searching for the meaning of the blink code but I saw no firm answers.

As the logo appears on screen, albeit briefly, it would suggest there is power and a good screen. A common design of the modern tv is the screen remaining black unless there is a signal to display, even self-generated signals such as menus, so perhaps the source of the problem is a fault that is preventing signal from reaching the video amplifier and scan section.

I have read during my search of people trying to fix the problem themselves and ended up spending the cost of a cheap tv and it still not working. As you are on a tight budget you need better value than that and that means a professional repair from somebody with experience, test gear and access to service manuals.
If I was in your position I would seek a friendly local repair guy and ask how much the cost is likely to be and then you can decide...

The tv that I have is an LG 42LB5600-UZ, but that wasn't one of the choices. The problem is that the television turns on... has a picture and sound, and then in about 30 seconds, the screen goes black but the sound continues. It is the same on every channel. It worked fine last night, but not today.

Please do a power cycle first,
unplugged the TV from your wall socket then check.

try to see if you can be able to hear a sound - if there is a sound it could be a back light problem -

If the Menu is displayed on the TV screen properly but the picture is still upside down, the problem might be due to an external device, such as a digital set top box or a transmission issue. Please check with your Manufacturer for the external device. The problem could have also been caused due to a signal issue. You could have a person that repairs TV's to take a look at your TV and see if there is a way to fix the screen being upside on the TV.

I believe its asking you to pair the TV's wireless remote. Follow mfgs instructions for pairing remote.

Check the output voltage from its SMPS power supply. You should have some experience in service work to proceed. It it seems OK, then check the main board [horizontal output section circuit] and pin-cushion circuit for defective component/s. If you wish to get some details; check the site linked here.
