    Hisense LCD Model TLM3233D

    HI guys, I have this LCD set with a rather unusual fault but am inexperienced in solving it and need ideas! The symptom is a overly luminous image. You can see the picture, even color but its very bright. If i adjust contrast and brightness to minimum you can see a slight darkening but it is still very bright. The set has one panel for power and inverter and another being the control board. From that board two flex ribbons go to the top of the lcd two a long thin pcb. The long thin pcb has a short ribbon going to another long thin board down the side of the tv. These two thin boards must be the decoding boards that connect direct to the lcd. The thing is that this set differs because there is supposed to be a T-Con board (Timing control) and this sits between the control board and LCD.
    I dont know where the fault may be situated, control board or those long thin pcb's. Perhaps a voltage supplying those boards is missing. HELP.

        "The symptom is a overly luminous image. You can see the picture, even color but its very bright." Can you show us the screen shot of what is shown on the screen? It sounds like bad GAMMA Voltage problem on the T-CON board.
        Also provide good clear pictures of the backside of the TV and all the boards.

          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...

          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...

          LG 60PK550 Logic Control Board EBR63450301
          by Yanleb
          Hi all, I just want to share the repair of my 60PK550-UA TV set.

          The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.

          But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.

          All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
          C57: 3.30V
          C61:...

          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....
