How come? Is it dead, you flashed the eeprom and still nothing is working? Can you attach a high resolution picture of your main board, so we can see what you did or tried to do?Last edited by CapLeaker; 02-19-2019, 01:52 PM. -

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

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

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.... -
Hello,
I own a Sony 49XH9505 123.2cm Smart Android 4k quite new bough brand new in 2021. Just after the warranty has expired it had died on me.
The symptoms are the following: right after turning on backlight turns on and this loading screen appears, than the display turns off and the red led flashes four times.
Any idea how to fix it or if it at least fixable? Does this sign related maybe some SoC/DSP and its circuits or just some simple power supply issues somewhere ?
Many thanks in advance, -
