    Insignia NS LCD42HD-09 no picture

    dad bought this thing from best buy brand new. but no extended warranties..etc..

    Worked fine for over 1.5 years...then during electrical storm, was not on surge protector..screen went black and never came back.

    Recently moved and I offered to take it under the guise that a repair person he knew said that it was likely a fuse on the board that went bad, he also took it to a repair shop which said same thing but he didnt want to pay labor+parts which were going to be more than the TV was new when he got it to fix so he replaced it and shoved it in the closet until I got it.

    Skip ahead...I have it...pop back off..can't find said fuse to replace, but find a cheap power board to swap with on ebay. Get it...tv does same thing. Light comes on, turns blue and holds with no sound or image. when i shut it off the LED blinks 14 or 15 times; which I have later learned is a hardware failure.

    So, its sat in the other room for close to 3 months now. I am uncertain if its the main board but posts like this and others lead me to believe it is so...or the backlight panels..or TCON, and I pulled the pin connectors off to test voltage going to main board, then realized I was uncertain which points I should look at to determine if this issue is same as the OP of this thread...

    any help is appreciated.

    I would lean towards changing the main board. You can check regulators on it but if its a fcried processor, you'll probably never know unless you get a service manual that tells you so.

      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...

      HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
      by m1ch43lzm
      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...

      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

      Samsung UN55H8000AF - No Picture, Working Backlight, Replaced T-Con Board
      by ermals
      Hi all!
      I've recently run into an issue with my Samsung UN55H8000AF LED TV displaying no image. I've done quite a bit of research in terms of what could be wrong with it. Below are the steps I've taken prior to reaching out here for some assistance:

      1. I've tried replacing the T-Con board (BN95-01594A), twice and have still experienced the same issue with all the boards I've tested with.
      2. I've tried to remove one side of the ribbon cable that goes from the T-Con board to the panel and still not getting any image on left or right side.
      3. I've checked voltages...

      Sony xbr-65x900c main board issues?
      by jb_Bak
      Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

      Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
      Power Board Connector that goes to Main board
      CN6401
      Pin 01 NC
      Pin 02 NC
      Pin 03 "BL_ON": 0V
      Pin 04 "N/C"
      Pin 05 "STBY 3.3V": 3.5V
      Pin 06 "GND": N/C
      Pin 07 "AC_OFF"...
