Good inverter not receiving power

I have a good inverter (came from a working machine) that doesnt seem to be receiving power. None of the LED lights on it are coming on, I have had the laptop on charge and on and the LED light still doesnt come turn on.

I have replaced the LED cable assembly, and the inverter still doesnt work. Needless to say the backlight on the LCD doesnt turn on either.

What else could it possibly be?

    Have you checked the power adapter to see if it is working?

    System came in with a broken screen, I replaced it and all was working for a few minutes, then it went dim. I suspected the inverter gave out due to the new screen so I replaced that but got the same issues. I tried a whole new lcd assembly which included the lcd, cable & inverter but still dim. Cannot find a lid switch. Also the inverter has led lights on it, all 3 inverters I have don't make those indicator lights light up. Im guessing the motherboard is the problem at this point but not sure exactly.

I have a samsung led smart tv 50 inch model UA50F6300AMXXY we have sound but no picture. when you shine a torch to the screen you can see images, any idea what the problem could be? Thanks


The inverter board that is used for led powering has failed or some of its connection isnt good. That is the reason that you can see picture but the panel doesnt light up. Try finding am inverter board for the specific model or send it back for repair claiming that it is their device malfunction.

Power board and back lights led tv


BL Inverter board fault. It's not working [oscillating]. 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.

I have a Toshiba L500-1DT. I replaced the broken screen, however now the screen doesn't seem to receiving any power although the computer is on.


This can go wrong in so many way it is hard to detect what may have happened here. Assuming you had CCFL screen (not LED), you could be forgetting to connect the power cable to the inverter. If you had a CCFL and tried to pop an LED replacement, you may have damaged the inverter (that transplant is not that simple). At any rate I would focus your troubleshooting energy on the inverter side and maybe buy a new inverter as a next step (if you have the screen out it is good practice to replace the inverter at the same time-they are cheap). If you tried to do a transplant CCFL-LED you may have damaged the board in the area that supplies power to the inverter, not an easy fix.

The power supply of lenovo h405 is working well because i transfer the power supply into different desktop pc is working but on my lenovo pc nothing is working none of the led is coming on when connec


okay if your PSU is working than have you checked the other hardware? for example check your MEMORY RAM sticks and check if they are properly in if they are out the pc will not start. also!
if the power supply is good than your motherboard should have an LED on it somewere look for it and power it on .. if this LED doesnt turn on than it means it gave out and you need to replace it .. cause of this? maybe a power surge or static or the light went out and came back and it fried it. i hope this helps

Not a lot to go on here, Prabhdeep

Need the full model information

Primer:

An LCD screen does not produce light,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

Click on the monitor icon

Because of this the LCD screen needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, (Or more than one), or a series of LED's.
(Light Emitting Diode)

CCFL = Cold Cathode Fluorescent Lamp (Bulb)
Similar to Fluorescent lighting used in homes, and businesses; but on a MUCH smaller scale.
Average thickness is 2mm, or a little more than 1/16th of an Inch.
Or about the width of this capital letter -> O <-
Average length is almost as long, as the LCD screen is in height.

(Do they break easily when trying to remove, and replace?
OH, YES!)

A screen Inverter is used to convert the power from the laptop, for the LCD screen, and Backlight.
If the laptop uses LED backlighting, it MAY or MAY NOT use a screen Inverter.
Generalized thinking (Can also be stated as 'Rule of Thumb'), is that if the laptop uses LED backlighting, it does NOT use a screen Inverter.

I also feel into this line of thinking, since none of the LED back-lit laptops seemed to use a screen Inverter; that came to the shop.
I have found this to be a fallacy from on here,......FixYa.....
I have looked up two laptops using LED backlighting, and discovered they also used a screen Inverter.

Now I post LED backlighting may, or may not use a screen Inverter.
Seems when LED backlighting first came out, a screen Inverter was used on some models.
Also seems as the LED backlighting technology progressed, no screen Inverter is used.

90 PERCENT of the time, the fault for bad Backlighting can be attributed to a bad screen Inverter.
Of course, this IS IF the laptop uses a screen Inverter.

For a laptop with LED backlighting that does not use a screen Inverter, and backlighting is bad (Dim, or non-existant), the next hardware part in the diagnoses to replace, is the LCD screen.

I now await the information I asked for above.
Then we can diagnose together.

Hi just plugged in brand new alba LED 169 11HDS. the screen comes on and it asks for language selection but the remote doesnt seem to be doing anything!


HI:
First make sure the batteries are in correctly, and are good, batteries that come with sets that sit in the store sometimes loose their power potential. A good check for the remote to see if its working is to, put you cell phone in camera mode and point the remote at the camera of your cell if you see the IR light flash while you push a button on the remote then the remote is working ok if not then the IR receiver in the set is faulty. At which point i would return the set to the Vendor..
