    Re: Toshiba 46TL963 3D LED Smart TV - No backlight

    Haven't got the tv yet but had a chance to buy it so I was just wondering if it's the dreaded LED bulb failure
    But I'll post when I get the TV

    Thanks

      Shopjimmy does not have any pictures of the boards for this model for me I can at least see how LED strips are connected to the board.

        @Budm a bit late but here is pictures as i am working on same tv just now. i used an led tested to test voltages going to the back-lights and one was slightly lower than the others. i cant seem to see any image on screen either though.

          Sorry to drag this post from the archives but can anyone point me in the direction of where to locate the led driver board for this model. Have looked everywhere and out of stock everywhere ��*♂️

            Since 2015/2017 the last post in this thread, LED backlight failure has become the number one issue with LED TVs. If the the backlights flash, turn off or don't come on at all, the backlights are the main suspect and not the led driver board.

              on Toshiba 46 TL series, the way to know LED back light issue. while the set on unplug and plug it fast the socket of 24V between power board and LED inverter boards which are on the left side of the power boards.. your backlight will come on again. ( SOS signal of turning off BL take effect only at start up the TV.. this why this method will by pass the sos signal)

                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...

                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...

                No Backlight Macbook A1990 820-01041
                by Comp_Pro
                Hello all,

                Am trying to figure out this backlight issue with this A1990 Macbook Pro.

                Tests performed:

                There is no backlight even with a good screen.
                Backlight IC is receiving the correct support voltages.
                Fuse F8400 ok
                Current sense resistor R8400 ok
                Backlight IC is receiving 3.3V on enable pin.
                Backlight IC receiving voltage from PPBUS_G3H, aprox 12.5V.
                Backlight IC receiving 5V from PP5V_G3S
                Backlight IC BKLT_SCL and BKLT_SDA both measure 0.545V diode mode to ground
                I2C_BKLT_SCL and I2C_BKLT_SDA both measure...

                Toshiba 55lf621c21 Dim Picture / Backlight afterbypassing a Burnt LED
                by willis6732
                Hello,

                This TV came in for a backlight Repair. I bypassed the Burnt LED as shown in Picture. I thought it was fixed and returned to customer. So I dont have the TV anymore, but customer says its not really watchable.

                Now the TV Is much dimmer than before. It does a quick bright flash when it first turns on.

                The Driver board looked pretty toasty in the LED Driver Area.

                So I am wondering.. how can i Tell if this is a LED or Driver Board Issue?...
