    Re: toshiba 50L1350U no backlight

    Can anyone help me out?
    Since i have the same exact TV and same symptoms i did not want to start a whole new thread.
    I was gaming today on the L1350U and after about 1 hour screen went black?
    still have audio and i did the flashlight test and can see a faint image of what is on the Screen.
    There is one thing that was NOT mentioned with the other L1350U TV's in this thread,
    Before this happened today, i had noticed when the screen was on my PC's desktop for windows 7 there was a subtle flickering in the upper right hand corner of the TV's screen?(approx a area of 3"x3" that flickered)
    I had noticed this a few days back and did not give it much thought until it went black today!
    Does this diagnose bad L.E.D's? or something else?

      Possibly bad connections in the Led strips here. Take the panel apart and get us some images of the Led.

        Is the back panel pretty easy to take off? I have seen some that are a real pain to get off?

                Toshiba 40L2400VQ No backlight but LEDs are fine
                by buchman
                Hi,
                I have a Toshiba LED tv model number 40L2400VQ.
                I don't receive the correct voltage at the output to the LEDs.

                I disassembled the front panel and checked all leds and they are fine. Then I checked the voltage to the leds on the power board and it flactuate in milivolts.
                Tested all caps with esr meter and they are fine.
                The diodes are fine and the resistors too.
                Where should I concentrate on?
                Thanks in advance....

                ASUS ROG Strix G713QR - Keyboard, backlight and side LEDs don't work
                by hollox123
                Hello, I have an "ASUS ROG Strix G713QR" laptop, and for approx. 3 months I have the following problems:

                1. Laptop keyboard doesn't work
                2. The backlight on the laptop keyboard doesn't work
                3. The x2 side LEDs (red) on the laptop don't work

                The power button works, the touchpad works, and all the USB, HDMI, Ethernet, etc. ports work.

                I already tried to reinstall all the drivers and reinstall Windows. So I don't know what to try anymore that is software-related.

                But I am strongly aiming that it is somehow a BIOS-related problem,...

                Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
                by maneatingmonkey
                I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

                There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

                Panasonic LED TV TC-40A420U - Replaced Backlight LEDs but now no image/display or garbled
                by signal.quest
                I have a Panasonic LED TV TC-40A420U. The TV was given to me as an attempt to fix or throw out. I replaced the Backlight LEDs and now the screen lights up, but there is no image/display. If I play with the up/down buttons I can get the display to change from black to garbled. I can't get sound from HDMI but not sure of what input is selected. I have no remote control. When I connect a laptop to the HDMI ports it recognizes a Panasonic TV for display and sound output but I can't see or hear anything through the TV. This makes me think the mainboard is OK, but not sure if mainboard can...

                Toshiba 39P2300VE, faulty backlight LEDs
                by spintop
                Hi

                No backlight issue with the TV.
                Opened up panel and found 3 bad leds in the panel.

                LED is about 3mm x 3mm, i assume they are the 3030 type. Label on the strip is :AG-D1 94V-O 1345 ( 6 leds in a strip )

                Thinking of buying and replacing the individual SMD leds. Found some online, but they have both 3V and 6V. Not sure which one i need, any idea how to tell ?

                Thank you....
