    Lg 37lc46-zc

    Hi, I have here a 37 inch LG tv, The red stanby LED comes on when set is plugged in and it turns green when i try power it on but i get no picture or backlight, Seems as though the TV is still functioning just no display or backlight is being produced.

    Is this a common problem on these sets and is it an easy fix?

    Thanks in advance for any help,

    Have you any photo's. Does it have sound. If you look very closely using a bright light can you see the menu on the screen when viewing from an angle.

          35V capacitor is seems like it's on the 24V backlight supply.

          Connect a DVD player to the scart input since most tv's automatically switch over to the scart input. You may have to switch the player on and off a few times for the TV to connect to it. Works for me for checking sound, volume up/down.

            Just came home for lunch and tried that cap in the tv and it fired up, Guess it was backlight then... I did honestly try a good bright led torch and couldn't see any image even when pressing menu button and a few others,

            Thanks for the help mate.. ;-)

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

                iPad Pro 12.9 5th Gen Backlight Issue
                by cheebster
                Hello, got an iPad Pro A2378 12.9 5th gen with no backlight. Got another test unit without screen, tested the screen, still no backlight with the test unit.
                Figured out the backlight on the screen was bad, ordred a new backlight from mobilesentrix, *carefully replaced it* without damaging the lcd, oh well.
                Final result, issue is still there, the screen has no back lights. So i'm back to square one, with 3 hours less and 100$ out, issue still on the screen.
                The panel is still ok, i can see the apple in the middle of the screen when it kicks in, just no backlight.
                Anyone...

                LG Flatron 24EN33TA No Backlight When Cold
                by canadaboy25
                Hi all,

                I've got an LG Flatron 24EN33TA with a backlight issue. The problem began with the monitor not powering up after sitting for a long time (overnight or during the day throughout work). When I would wake the computer up, the backlight would flick on for a second then go out. Sometimes it would take many tries to get it to come on. Once the monitor came on, it worked flawlessly until another long duration of being powered off.

                I thought the problem would be bad caps but I checked both of the caps on the board and they are fine. I also tried powering the monitor from...
