    Sony KDL-55W800A green / amber status flash

    Hi guys,

    I'm a newbie to all this stuff so any help would be greatly appreciated...

    My initial problem was I had the red light blinking three times, after all checks in the service manual, proceeded to replace the BA2S (main)board as it was the most likely cause, now after powering on the TV, the green and amber status LEDs flash on an oscillating basis...

    I have downloaded the latest firmware from the Sony website, formatted a USB stick to FAT32 and copied to the root folder of the USB. The TV when powering up reads the USB drive and flashes a couple of times but then stops. This has now been on for about an hour, still no progress, just flashing amber, green, amber, green...

    When the TV powers up, the white status LED comes on, the panel LED backlight flashes for 1/2 second and then the green/amber starts flashing.

    Is there another way to "force" update the firmware on the TV? I don't have the original remote, if I get one and do a reset, will this work to enable me to get into the settings menu, or is there anything else I could try first?

    Thanks

      First we need to see some high resolution, straight shot pictures of all your boards and another one of the backside of the TV to see how all is connected together.

      Did you try unhooking everything but the backlights from the PSU and force the PSU on? Once the PSU is up and running, do the backlights stay on and all voltage rails on the secondary are up and running?

                  i downloaded firmware from sony and there is no .pkg fike.. after extracting it gives another file which contains multiple files like inf, payload.bin and 3, 4 other files. i just did that usb but did not worked. anyone knows anything how to do it..?

                  green amber blinking stops after while and then starts again. tv responds to remote control on off etc. before installing new tcon backlite was coming on without backlite...

                  4 red flash led 65X950G boot Sony and android logo but then black
                  by Ihandyrepair
                  HI guys

                  I got here a Sony 65X950G - I tried to find any repairs guides for this model but not many online

                  here is the issue
                  I have Sony and android logo. but then 4 led red flash lights front of the tv

                  I have 3.3v ref. 12v reg then T con 12v when I press the power on button
                  but then I get black screen and 4 red flash light at the front LED
                  but I get 3 led flash on the LED driver board.

                  I check that few X900F or C YouTube repairs, seems that if you have 4 led red flash it could be due of LED black light error
                  so I tried...

                  Sony KDL-55W755C - Dead
                  by mrsith
                  Hello again lifesavers.

                  I have a KDL-55W755c that came in dead - not even standby light going on. Tested the power supply - all correct. Tested the output pins on the Led driver board (in which the power cord plugs in) - all seemed fine.
                  I got a service manual for this model and tested the DC/DC converter by checking voltages on selected components. Every voltage was present where it should be. Service manual says that in this case a "Muffin" replacement is needed. This is the moment where I got stuck as I wasn't able to Google my way through it - till this day I...

                  [Help] Lenovo Yoga Slim 7-14ARE05 (DA0LS3MBAF0) – 25Q80DVN1G Flash Is All FF, USB-C PD Stuck at 5V
                  by ekozeko333
                  Hi all,
                  I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
                  🔥 The Problem Started After Suspected ESD/PD Fault
                  I experienced a power issue or ESD event through a USB-C charger
                  After that, the NX20P5090 power switch was visibly burned and was replaced
                  Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
                  🧠 What I’ve Done So Far
                  Flashed...

                  Nikon D800 camera - flash don’t work and capacitor don’t charge
                  by corrize
                  Hello, I'm stuck in troubleshooting…
                  The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.

                  In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
                  When I press the flash button, it's detected by the system, flash icon appear on LDC display....
