    HITACHI 32HXC01U - No backlight

    Hi All,

    My spare TV is a Hitachi 32HXC01U and the backlight recently failed. Everything else seems fine - it happily goes into standby, the audio is still working, and a picture is visible when I manually illuminate the screen, so I assume there is just a problem backlight.

    I popped it open yesterday to see what was going on and the board is a Vestal 17IPS19-5 V.1 061112. I assume it was a problem, with the LED driver however I guess it could be a problem with the LEDs themselves. So does anyone have any idea how I can diagnose the actual problem?

    Sorry if that is a bit of a stupid question, although I am reasonably confident with electronics generally, I have never tried to repair a TV before, so don't really know where to start...

    I have attached pictures of the whole tv chassis and both of the individual boards. Sorry about the poor photography - it was dark when I took the pictures and my phones camera flash isn't great.Happy ot take more in daylight if it will help.

    Any help would be appreciated.

    Cheers,

    Alex

      To rule out a faulty driver. Turn the tv on, do you have 24v at the positive pin of the driver ? If so driver is good if not driver is bad.

          Vizio E55-F1 dark backlight zones. LED failure or Dimming Zone Driver?
          by howardc64
          Problem

          Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video



          Model & Board Pics



          Conflicting Spec

          Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12

          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...

          Hitachi 40HYC42
          by dragometin
          TV Model: Hitachi 40HYC42
          Power Supply: 17IPS71
          MainBoard: 17MB95M
          Panel: VES400UNDS-2D-NO3

          When the set came in it was dead. Fuse was open primary side and the power mosfet was shorted. So I ordered a new power supply. Now it turns on, only displays "Hitachi" and then power off red and blue led flashing.

          I had to modify the 0ohm resistors in the led backlight of the new PS like the original power supply.
          Is there any variants on 17IPS71 power supply's?

          UART output pins 10 and 12 on scart connector:

          LED DRIVER KEEPS DYING
          by osrex
          Hello, this is my first post and im just a beginner, so be easy on me guy. thanks



          i have a LED chandeilier that switches colors from white to cool white to warm when toggling the switch, it has 24 LED arms, each arm is 30 CM length.



          i have no datasheet at all for the LED lights, all i have is its length.



          long story short, testing the chandelier on the ground, and it works fine for 1 - 2 - 6 hours, no problem.



          as soon as i fix the chandelier to the ceiling and bury the driver inside the hub,...

          Guide me through repairing a Dell p2210f LCD ccfl backlight monitor
          by DanPoka
          I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
          Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
          This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered...
