    Good call. It'd be a snap to build a basic power supply and shazam!

      If you want to isolate the failed LED, you can use a multimeter in diode test mode. If there are no test points, scrape the soldermask beside each LED.

        Re: Insignia NS-48D510NA15 no backlight

        Newbie here. I also have the Insignia NS-48D510NA15 with no backlight. I was able to take it apart and used two 9V batteries in succession to test each strip. One strip appears to be bad, as I could not get it to light up. Should I assume when one strip is bad, none will light up? If so, should I replace the one bad strip or all of them? Thanks for any help. As I said, I am a newbie with TV's, so any help would be appreciated.

          All the LEDs have wear and the ones still working are likely to fail. If you don't want a repeat failure, replace all of them with new and turn down the backlight level.

            Thanks for the reply. Where is the best place to buy the LED's? How do you turn down the backlight level? Thanks for your help.

              Ordered these recently. They were a little bit thinner than the original strips so just taped them down with shipping tape. You can turn down the backlight in the picture settings menu. I would also turn off the ambient light sensor.

                Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                by Tynan Dill
                I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                Upon bringing it home and plugging it up, it showed a standby light.

                I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                The screen seems to blackout and stay black, but with a flashlight I can see the display.

                With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                Assuming...

                Problem

                This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                by howardc64
                All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
