      Ya my advice. Put the back on pretend you never opened it up. Stick with repairing lcd

              Its most likely more caps that are failed but have not blew up, replace all Samwha WB and WL brand capacitors on the power supply first.

                      Since there is a LOT of board, can you help me to clarify which board is what

                      I mean, the one where the power cord go is the power board but there is only one HUGE capacitor, then, the wires goes to the central board, is that another power board?

                      thanks

                          I repaired a bad caps on the power board but the problem is still there, I have tested the buffer board (http://blog.coppelltvrepair.com/2010...-lines-in.html) but they seem ok too...

                              What voltages are you getting? Are you getting vs va voltages? No then try disconnecting y and x mains and see if it turns on. Still no va and vs? then focus there,,, getting standby on powerboard?. Is mains sending on signal? Your va and vs voltage reference is on a sticker back of panel.





                              Looking at the back of set your y main is on left connected to buffers. On right is your x main , center is power board and mainboard is obvious and below the powerboard. The smaller board next to powerboard with all the flat ribbons going to it is like your tcon in lcds. Btw this plasma has a split power supply design hence 2 boards might be 3 hard to tell with fuzzy picture. I worked on a 60 inch vizio that has a tripple power supply design before.

                                  [Help] Lenovo Yoga Slim 7-14ARE05 (DA0LS3MBAF0) – 25Q80DVN1G Flash Is All FF, USB-C PD Stuck at 5V

                                  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

                                  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....

                                  Canon VIXIA HF S10 A read data from inernal flash memory.
                                  by abajor
                                  Hello I've had somebody bring in one of these charming little cameras to attempt retrieving data from the internal 32GB flash.
                                  Something is damaged inside the cameras lens assembly I can hear it clunking around and it has probably dislodged the sensor, powering up the camera gives a blank screen and the focus motor sounds like it's having a fit.
                                  The camera will not connect to a computer via USB in this state, I have no options no navigation, just power up and focus/zoom motor noises.

                                  I think my best shot is to figure out a way to read the internal flash memory outside...

                                  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...

                                  Help Disabling Flash Protection Range Registers on Lenovo P360 Tiny BIOS
                                  by abhorsen
                                  Hey guys,

                                  Hope you all are doing well. I come here from Win-Raid because I am having issues disabling Flash Protection Range Registers so I can flash my BIOS from within Windows using Intel's IFW tool/using flashrom within Linux, however I cannot due to the above mentioned error.

                                  Here is my thread on Win-Raid detailing the whole process I went through: https://winraid.level1techs.com/t/re...h-gen/95478/27

                                  Essentially I managed to boot into Windows while shorting PINs 1+5 of my audio chip to disable the HAP bit...
