Press the three key Ctrl+Alt+delete from your keypad when you see that black screen with cursor blinking,the scree will come up automatically or else try to switch the notebook in safe mode by following these instruction:
1. Turn on the notebook and keep pressing the F8 key from your keypad
2. You will find options like --Safe mode
--Safe mode with Networking
--Start window Normally
3. You need to select the Safe mode with networking option and then press enter from your keypad

This way you can get into the safe mode and you can easily use the notebook.

SOURCE: My LG model 47LN5700-uh TV turns on, flashes the LG logo and then powers off, what should I check to see if it is defective?

I had the same model with the exact same problem last week in my shop, it turned out to be a firmware issue, went online downloaded the firmware to a flash drive and into the TV and it worked fine after that, not saying this is your problem but I had checked both the power board and main and found nothing bad so that is when I reverted to the firmware issue

Will LED power supply fix my black screen on TV?


Chances are you have bad lamps in the panel...you will need to take the front cover off and get under the panel and test them and see if some are bad, if they are replace the strip...good luck as its not all that easy to get the panel off and back on without damaging it, use extreme care handling it or once you get the lamps working the panel can be damaged and then it has to be recycled as it can't be fixed

Your Main PCB is faulty. LG is version specific. There are additional letters after the "UA" in the model number located below were you found that one. The complete model number is also located on a small rectangular sticker near the edge of the TV on the back. Use the entire number when searching online for a replacement.

Please check the LED back lights strips, it is a common problem for your TV symptom.

Yes, when you power down the power, the back lights may flash on.

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.

First:
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)

Second:
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

FREEZING OF PHONE


Hi, when a phone randomly freezes, it means that the phones memory is faulty or when an application you downloaded has virus.

What to do is this,

You will have to flash the phone to restore the memory of the phone.

You can use this link to see how to flash your phone.

Take care.

My lg chocolate won't turn on, just keeps flashing the Verizon Logo


Flashing the logo means that the LCD is fine and kicking. You must get the phone's firmware reinstalled. The reason of flashing Verizon Logo is that it cant read or follow the instructions beyond the logo stage. So, give it the stuff to read or follow. Reinstall the firmware and you will find that everything moves smoothly.
