Depending on your electronics skill, they can be replaced with new replacement boards. Usually the inverter boards that drive the backlights tend to blow. Soo its not really an expertise repair unless you know what your doing. The lcd tv's ive fixed the backlights are all on a 2 pin connector.

Most a likely a problem with your Y-Sustain board which will then not drive the screen giving a black picture. The fuse on the board may be open circuit & need replaced but most likely you will need to have the sustain board replaced.

Most probably the capacitors in the power supply have burst. Might need attention by a qualified service technician.

LED TV screen has flickered momentarily and faded to black. I have sound and power buttons light up. LED solid black, not lit. Bad LED Driver board?


Sounds like Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

LG tv black screen with sound


Hi Tommy,
This is a common problem with LG LEDs. It is a backlight failure. Either the backlights are not receiving the power to drive them or some of the LEDs in the backlight array have failed.
I hope it helps.
Good Luck.

My LG 55LE5400 TV will not show a picture. The screen is black. I was watching a movie and it just went off.


Hi,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Picture freezes then shuts off and restarts.


First of all, shame on LG for not providing support on their product. It sounds like this TV isn't that old. I was just bragging on them to several people this week. Your symptoms sounds like a main board issue. But in order to be sure, proper troubleshooting will need to be done to pinpoint the problem. You will have to pay a diagnosis fee, usually $75 range, but for a 55" late model set, I would say it is worth the money. So sorry to hear this, I'm hearing so many of these late model LED TV's failing left and right.
