    Finlux 32h7072-no backlight

    I have a Finlux 3d model 32h7072-dt and last night when i was watching a tv program the screen went off.
    The tv starts,has sound and picture(when i look very close i can see it) but no light on the screen....everything else works...if i press menu i can (barely) see it
    When i start the tv sometimes it has backlight light for a second or so....sometimes i can see it's connected to hdmi1....I have minimum to medium knowledge about electronics...someone can help me...where to start from?
    Any help will be appreciated.

        I have atached the pictures:full back and each board...sorry about landscape/portrait mode...i was trying to get a closer and clear picture.
        I've looked at the psu board and there is nothing showing damaged...no blowed caps or some other signs
        I did make a test on the led output...when i power up the tv is somewhere around 90v then drops and fluctuates between 27.1-27.3v

                  Finlux LED backlight not working
                  by stoian_93
                  Hello guys!
                  My Finlux TV backlight stopped working. I disassembled the TV, saw I don't have the tools to replace the backlight and assembled it again without replacing anything. So then the backlight started working again.
                  A day after it is also not working.
                  I decided now to remove the back cover and get the output voltage to the backlight. I placed the TV facedown and connected to the mains, so - nothing. I disconected, removed the cover and connected again to the mains and then the backlight lighted again. So strange.
                  Output voltage when light is 66V.
                  Board: VESTEL...

                  EIZO CX270 - No signal but Backlight and Panel works, logo works, admin menu works. OSD doesn't. What?!
                  by vf fa
                  Hi, so i guess Iยดll have to make a new topic here, as i browsed through hundreds of other threads but couldn't find a solution to my problem yet.

                  I got a EIZO CX270 from a friend. He said it doesn't work anymore and wont display any signal or take any OSD inputs. Well, as an aspiring photographer I couldn't say no, could I? Thought it was an easy game, replace a bad cap and have a working monitor. But nooope, it wasn't supposed to be this easy.

                  So let me start with the problem description. I'll try my best not to skip anything so this might get rather long.

                  UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!

                  this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
                  i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
                  unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
                  according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

                  Vizio D32f-E1 Powers on, has backlight, won't boot/no logo, no menu or video
                  by JaquesPratt
                  I have a Vizio D32f-E1 LCD TV that does NOT have a TCON board.

                  This TV recently went through some 'death throes' and now won't boot. The first problem that began to manifest was while watching tv, the screen would 'freeze', and the image would dim over a few seconds until it was very dark. HOWEVER, the audio of the show would continue as normal. I could power off the TV for 5-20 seconds, power back on, and the video would be normal. This would occur 1-3 times when the TV was first started, and would not happen again after the TV was 'warmed up'. Not ideal, but this glitch was manageable....
