    JVC EM32TS LED - No Display, yes backlight

    Hi all,

    I'm new to TV repair. Thanks for any and all help.

    I have this LED TV that lights up, but the screen stays black. I can tell the backlight or leds come on though, but no image. I can't find a service manual for it. Any help or direction on this one?

        on the photos i didn't have any of the cables connected. i had already unplugged everything before remembering to take photos lol.

        i did not test sound. i can hook something up real quick to play a movie so sound comes through. let me go check

            yes, that was just because i laid the board in there just for a photo. i unhooked the cable.

            and i cannot test sound because I cannot change the input on the tv because I cannot see the display.

            i did notice some vertical lines where the channel numbers were

              its complex to trouble shoot ,, as the boards all in one. but one things you can do,, take the boards out.. and with yours DMM on Diode peep ton method check all SMD component No started with FB they are fuseable SMD parts.

              good lucks

                Just a quick thought to help....use either the remote or the tv's control buttons to cycle through inputs...you don't have to see them on screen...just listen as you have a dvd, a tv channel, etc, playing until you hear sound. If you've cycled through as many connects as you know you have, then probably no sound working.

                      check voltages on led panel driver board.check VGL/VGH/HAVDD/AVDD/3.3v/1.8v
                      specially the VIN voltage

                          SF314-41 BIOS without internal display
                          by lanovey
                          Hello there,
                          I have a SF314-41 motherboard that i bought impulsively recently, the problem is that i only bought the motherboard only, nothing else. When i tried powering on the board with 19V (soldered on the DC IN port), and then shorting the pin 1-2 of the keyboard, the board is turning on (as indicated by the fan), however it seems like the board is displaying on the internal display as connecting to a display on the HDMI (external) does not display anything.
                          I tried connecting a USB keyboard, the keyboard is powered on, however pressing numlock do nothing (supposed to toggle...

                          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....

                          Acer XF240Y display backlight on and off then stays on but no display
                          by dbuergi
                          Hi all,

                          my display shows some strange bevahior. The backlight turns on, off and then stays on but i get no display or Acers logo. After some time it goes into standby. My notebook identifys the screen when i connect it by HDMI but i don't get an image.
                          Voltages seem n​ormal and the only possible problem i found is the cap on C33 on the tcom board. It shows 0 Ohm and 0V in diode testing. Any ideas for next steps or what i can check?...

                          by MtapeK
                          Hello I have an 820-01041-A that does not have BOTH display and Backlight. The MBP was working properly to wake up without Display overnight. I have Tried SMC and NVRAM reset they both are not solving my Problem. The CapsLock on the KeyBoard, is working when you power it ON, and when you plug the Charger it's Responding with a sound that signifies the MBP has BOOTED in to SYSTEM. I have tried an HDMI (external Screen) its NOT Displaying anything. Also the INTERNAL Display Shows nothing.
                          1. I have Changed U9850 and the results are still the same, Discovered that the IC is working on a Good Known
