    Sony VPCZ1 backlight circuit

    I've got an Sony VPCZ12Z9E (PCG-31111M) with an bad backlight power circuit. The screen and motherboard have been replaced by the owner (His kid stepped over it) but the screen arrived much latter and upon installing it displayed no image, that is, it displayed an image without an backlight.

    I have measured voltages across two big caps and their coil near the LCD connector and they read 0V.

                  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...

                  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...

                  Sony XBR 49x900E - Sound and backlight on but no picture
                  by DKWS89
                  Hey Guys,

                  So a few months ago my Sony XBR 49x900e TV screen stopped displaying the picture but the backlight comes on and I still get sound when I use the remote and navigate to certain apps. I haven't checked anything with the meter yet but started with ordering some replacement boards. I've tried replacing the BMKS board (used from ebay) and also completed the firmware upgrade based on Nicks TV repairs youtube video. I've also replaced the TCON (twice) and PIB.

                  All of these changes have resulted in the same issue with no picture. I've also tried disconnecting the ribbons...

                  (All the Electrolytics are brand new.)

                  I started a new one, hope that's ok, because my question is different now! (Strangely enough, after I walked away for a few weeks, it stopped lighting up at all!!)
                  I am determined to fix this power supply because I have the skills to replace bad components, I just need to find out...

                  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...
