Question about Samsung Electronics UN55EH6000 - 55in Class 54.6in viewable LED-backlit LCD TV

2 Answers

Samsung UN55EH6000 has audio, but no backlight LED as seen with flashlight test.

As described above, sound ok and no LED backlight. I am suspecting Power supply/ led board BN44-00499A is the culprit. Any opinions out there? Might try replacing the board. Thanks Kevin

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.

My lg TV of three and half years has a black screen with images flashin Intermittently. The sound is fine


What is the model number? If it is only 3 years old, I suspect you have a LCD TV with LED backlight. You quite possibly have a failed LED backlight.

Many LG TVs of this age are starting to fail due to over-worked LEDs in the backlight which create the white light that illuminates the LCD image.

The symptom is TV turns on and off ok, gets sound on the connected video inputs, but has an otherwise black screen with no video on display. You can try to operate the TV near a bright window with lots of sunlight and see if you can perceive a faint image on the screen. A flashlight is often not bright enough to be helpful.

Most of the time, an LED will fail as a short circuit and still allow power to flow through it to other LEDs that will still light up. If one of these LEDs fails as an "open circuit", or if several LEDs have failed in the same circuit, then the power supply detects a fault and shuts the TV down. If the LED is intermittent, you may have flickering. Think of having one light bulb burn out in a string of Christmas lights and having all the lights go out until the bad bulb is replaced... kind of the same thing.

Your TV circuits boards should be fine. In my opinion your TV requires a backlight repair which requires complete disassembly of the entire TV including disassembly of the panel which is a difficult process.

Samsung TV (model UN40H6203AF) 40" LED. No picture, have sound. Flashlight test can see faint menu screen. Have replaced power supply & main boards to this point. Ideas as to what to do next?


Hi Terry,

If you can see the faint picture in flash light means the power supply and the main board is working. The real culprit is the backlight. Even one bad LED in the backlight will switch off the whole array. To repair this fault the panel has to be opened and the defective LED or LEDs are to be replaced.

This is a complicated, delicate and risky job and must be attempted by an expert only. You may end up damaging the screen permanently if you have not done it before and try to DIY.

LG 42LN5400-UA.BUSYLHR back lights not working, sound working, flashlight test shows video working.


This is a common problem for LG 42LN5xxx & 47LN5xxx LED TVs, the problem is defective LED back lights strips, it has nothing to do with main power supply & the main board.

Sanyo DP46142 TV comes on for approximately 30 seconds and then screen goes black. Power LED stays on.


Sounds like a backlight problem to me. If you input a signal to the HDMI or Composite input and then it goes black have you tried taking a flashlight to the screen to see if the picture is still there but just dark? That would indicate a backlight issue. That model appears to be an LED edge lit backlight, so if the picture is still there after going black your going to have to trace out the backlight circuit and see whats going on. Usually with LED backlighting if it comes on at all then the LED's are good, its just the driver supply thats failing to keep them on. Some TV's have a small separate board that provides the backlight control, but i suspect with this model its on the power supply board and not the motherboard. Have you checked that board? It could be bad caps on the power supply board, check the voltages to the backlighting when it lights up and then when it goes dark. It could just be some failed capacitors on the power supply causing that voltage rail to drop off.

Toshiba led lcd


There is no 'bulb' in LCD/LED tv.
The back light is LCD or LED only.
The shopJimmy also point to the bad inverter and/or LED driver
you should evaluate the cost of part + age of tv vs new

Why is my replacement LED Power Supply Board not functioning properly?


Power supply board is not the culprit - check out your inverter board which is responsible for the back lighting.

There is sound but no picture. No backlights but can see a picture in dark with flashlight test. LED panel # is D460D3-6Y43-COX. What part would I need to purchase? T


You have check the power supply first .To know how to check the power supply watch the following video. Normally led tvs power supply contains the led drive circuit too. Bot are integrated in the same board. The led drives circuit should have between 30 to 120 volts from the power section depending up on the brand and model number of the TV. If the the voltage is ok then you have problem with the Led driver section section. Either you can try to repair it or can buy a new power board.
