My samsung LED TV has no picture but has sound. I can see the image with flashlight. What's wrong with it?

This means that the backlight has failed. Depending on the age of the TV, this light is provided by compact fluorescent tubes or LED lights and brightens the light emitted by the LCD panel of the unit. On most older TVs the back lights are on the sides of the LCD panel. Repairing the backlight requires taking apart the bezel of the TV. Then you peel off the foil tape and carefully separate the lights from the unit, including disconnecting the ribbon cable that provide the power to the lights. You have to replace the lights with ones of the same size. Then put the new lights and seal the panel. Finally you close up the bezel.

Without the model of the TV, I can't tell which type of backlight you need. has some replacements. The entire process is difficult and it is possible to break the LCD screen if you make a mistake. For any TV under about 40", you won't find most repair shops willing to do the work for less than the cost of a new TV. If the TV is under warranty (1 year usually), contact Samsung.

I hope this helps.

When I turn on my tv, the screen lights up for about 5 seconds then goes black

Hello, the most common problem on this set is a backlight problem. about 85% of the time it's the backlight inverter board that fails, but sometimes the CCFL tubes in the LCD panel can fail, if anyone of the 8 to 20 CCFL tubes depending on screen size fail, the set shuts down. you can find the inverter boards on ebay or shopjimmy if want to try that for under $50,,,,,thanks, Terry

Screen dull on Janome mc 8000

There is an LCD Backlight Panel that illuminates the screen, and yes, they do fail.
Before you start, just check the screen contrast dial inside the top cover, front right, they can be easily knocked and this will also cause the screen to go light or dark.
Janome no longer supplies the LCD Backlight, however, we have an after market replacement at our store, and also provide fitting instructions and a good deal more besides.
If you care to contact me I can send a Diagnostic Routine and the Screen Reset instructions for you to check if there is anything else causing troubles.
Please remember to give details of your dilemma as we do receive a lot of requests.

Power ok no display

Tilt the screen so that light strikes it at an angle

If you look carefully at the screen can you see an image in the background.

If you can then the inverter for the backlight or the backlight itself has failed

No image is the LCD

Cheaper to buy another monitor !!!

The screen is black but if you look hard you can see the background very lightly

Hi, your monitor's backlight is burned out or malfunctioning. The LCD monitor consists of two major parts - the LCD panel where images are created, and the backlight which forces light to pass through the LCD panel so you can see things. Your backlight is out. Viewsonic has great warranty support and service. You should contact them, provide them with the serial number, and they'll probably repair it under warranty for you. This is a hardware malfunction, so it needs to be repaired.

Bose P1 - lost backlight

Bose support repaired two P1 remotes for me. The first one they did for free (well out of the warranty period). The second one in the last 18 months cost $50 for a complete rebuild, new case, etc.

Janome memory craft 8000

We have about 30 electroluminescent backlights for the 8000 still available .These are not original Janome parts. You will need a Janome service person to install then for you as it requires taking apart alot of the machine to get to the display. We can provide instructions if this person is unsure how to fit. Once the display is out, the process is simple. They are AUD$60 each including shipping. Email at
