Model lg42ln5700-uh. Why does it turn on, displays the LG logo, then turns off?

Hi Tony

Sorry.... previous was a lazy answer... at the end of a long day.

Your TV attempts to turn on, finds a problem, then turns off!

This is because the TV has a smart electronic power supply that can sense certain problems. Like overheating or it senses excess current draw from other circuits.
Everything is fine until about the time the logo appears then shuts itself down.

Check that the tv is getting ventilation.
No blocked air holes, as they use convection to cool the insides. Hot air out top, cool air in bottom.
Take a photo on your iPhone of the rear connections.
Remove all connections from rear in case they are adding to the problem.
Tap or slap the back a few times on startup to see if movement plays any part in the fault. Loose Connectors.

A modern tv works very much like a desktop computer.
No internal nobs or adjustments any more.
It's all CPU, Memory, Video memory on a circuit board.

If you feel comfortable with opening it up and checking inside then you might see the problem and be able to fix or replace a faulty module.
But... if the tv has just one large circuit board, thats little tougher to replace (& expensive)

With the back removed, check for loose connectors / wires,dust. Cockroach residue or nests, cause copper track shorts on circuit boards.
Follow the AC power lead to where it attaches to the electronics.
This will be the switch mode power supply.
This is where most modern electronics devices get their problems.
Look at the Electrolytic Capacitors on this board. The small round tin cans with an x on top.
Do any of them have a bulge in the top?
If so, the cap is probably Bad & needs replacing,
They also sometimes leak brown fluid from their bottom onto the printed circuit board.
You would either replace or repair this electronic module.
Turn Power On.... all working

Good Luck

Why does 15 amp 250 volt fuse in my lg refridgerator keep blowing

the 15 amp fuse is blowing because the current draw to run the compressor exceeds 15 amps
that problem could be from a failed start/ run capacitor or a failed compressor motor (I am betting on the capacitor)
the best answer is to get a fridge technician to check it out as the capacitor is a cheap fix while the compressor unit is as costly as a new fridge

You need to pull the draw right out & get a pin or tooth pick & unblock the holes where the water comes in.

What problem occour when unit take high ampere.

When a unit starts to draw high amps, you start loosing motors, the compressor ect. If there is a problem with one of the componants, it will over amp and cause it to burn out. Each motor has a factory set amp rating on it and as it gets older and worn, it draws more current causing it to over heat and finally give out. It is important to have the unit serviced to keep the unit running as good as new. That is what occurs, burned out motors.

Maximum power draw

Should have a name plate that lists the wattage or amperage.
Typically Dryers have 4000 to 5000 watt elements and have to be fused at 30 Amp. (Or breaker must be 30A)
Motor is much less current or wattage. The element uses the lion's share of power.
I looked for a manual but LG doesn't have one available.
