My LG tv model number 42LN5400-UA no picture

It is a common problem for the LG 42/47 LN series LED TV, the problem is defective LED back lights strip (strips).

You have to open the display panel to find the bad one & replace it. The part number usually is printed on the strips, read 6916L-11XXA, you may purchase it from EBay.

The display on my HP Pavilion dv5220us laptop has stopped working. I can use an external monitor, but the main display just glows ever so slightly. Occasionally, there is a single line across the display....

It sounds like either the LCD cable that runs from the video card to the LCD is bad, or the LCD itself is bad. If you feel comfortable taking it apart, examine the cable for physical damage such as a worn spot from rubbing as the lid is opened and closed.

If there is no damage like this the cable could still be bad (broken wire inside) but more likely it is the screen.

Either way, you should be able to find a replacement on eBay, etc.

It is good that the external monitor works as this eliminates the system board, video card, and OS as culprits, also the fact that the screen glows shows that the inverter and backlight are good.

Turns on with a louder click than usual,then nothing just glows

Mainboard damaged and need to be replaced, try EBAY for a general picture of prices but you will need your product code wich is located in the back of the TV next to serial number.
