Re: LC-70C6500U 3 Slow Flashes and Fast Flash
you can try the "standard" disconnect one tcon to panel cable at a time and see if anything happens / changes. You also might have to do a "force on" sequence to get the set to start depending on how the error has been set. -

I have an LC-70C6600U here right now. Hold these buttons simultaneously and see if the TV turns on.
Volume down
Channel up
Power
You may have to hold these buttons down and plug the TV in at the same time to work. Try with it plugged in first. If it appears to turn on shine a bright flashlight upon the screen and see if you see any image in there.
My 6600U had shorted Gate Driver ICs on the left side of the screen with the 1-1 error code.They call me......."threadkiller"

AFAIK schematics or boardview are not available for this MB, but I used a similar board as a reference (G7AL-2G)
Laptop came in not booting with caps lock blinking 3 fast- 2 slow indicating RAM error. Charging works fine. Found bad soldering on the only ram socket present (2 outer left pins and 2 outer right pins).
Once soldered the laptop started fine and I was able to install Windows 11, upgrade BIOS to version F30 from Windows without a problem, BUT I found a strange and annoying... -
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.... -
It's been a while since I've checked in here or needed input on narrowing down what to replace on a TV repair, but I've got one on my bench now that has me wondering. The lack of part (board) availability means I may need to do some component-level diagnostics, and a second opinion is always good when it comes to that.
The issue - Sharp LC-80LE844U does not display. Power light comes on for a while, then you can hear a relay click off and the light blinks twice slow, then five times fast. Service manual points to 'Panel Power Supply Error' with this code, but isn't much more help... -
Hello all,
I'm trying to repair this A2251 macbook pro. Board is 820-01949. The original issue was liquid damage which all cleaned up well and the board was not heavily damaged. Unfortunately after liquid damage cleaning the computer is running extremely slow and the fan is running at full speed. Even the cursor is lagging. Because of this I can't use the built in hardware diagnostic to give me a clue as to what is happening. Does anyone know if Apple Service Diagnostic software is available for this model? Any other clues which could help me out? Seems to me there is an issue with...
