    Technika LED TV flickering background.

    hi guys i have here a Technika Led TV with background light flickering constantly every second.
    i tested the power board with inverter cable disconnected from power board and every thing is ok except 24V for inverter which is 20V and dropping and get back to 20V every second.
    I have attached pics with the power board and main board.
    Any ideas?
    Thanks

          but why is power board supplying only 20V and dropping voltage there without cable connected?

              Same thing happens when inverter cable is connected.

                      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...

                      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...

                      Technika lcd 32 - 207, question about board compatibility
                      by rustinjust
                      My main board is a 17MB12-2 and reads underneath that the following number 160807 LF,
                      Question is this board going to fit? ( see link) board is identical but from a different brand of tv but board number is same as in that it’s a 17mb12-2 board
                      Link to part here https://www.ebay.co.uk/itm/222990805243

                      This board is cheapest I can find. Also note:ordered one that was from a technica, an exact replacement, it arrived yesterday and when I fitted it it was a dead board, didn’t even show the standby light. When I piut the old board back in the tv worked but the issue...

                      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

                      Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
                      by lostone
                      Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

                      First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
                      When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...
