hello everyone
i have a problem to a1706
First of all, it was delivered because the power was not turned on.
5v was confirmed on the voltage meter.
The battery was removed and checked.
A short was confirmed in the ppvin_g3h_p3v3g3h line.
During the tracking process, u7000 and d6902 were replaced and u6903 was reballed.
The cause was c7081, and when I removed it, the short went away.
However, 5v still came out from the voltage switch, and I confirmed that a short was coming out of the l6900....

I get backlights that stay on not there is no image. The tv does not automatically power on when plugged in either which I generally see happen when there is a fault. It responds as it should to the power button.
I checked the test points on the TCON and I have proper voltages except for at 1P15V. I don't know if that is supposed to be 15V or 5V, but either way I only get 1.134V on that point. I have 12V, 8V, VCC, and a small amount on the CKV point.
I tried heating up the SoC on the main board but that made no difference. Disconnecting either ribbon from the TCON also...06-01-2024, 08:55 PM -
Hello guys, can someone help me with an eMMC dump for a Sony KDL55W-955B TV, I tried to read the original memory with the RT809H but it shows me that it only has 1888MB even though it should have around 3.8GB. On a new memory it shows me 3776MB. From what I found on the Sony page, the following models could also be compatible:
KDL-65W955B, KDL-55W955B, KDL-60W855B, KDL-50W805B, KDL-42W705B, KDL-32W705B, KDL-48W605B, KDL-40W605B, KDL-60W605B, KDL-55W805B, KDL-42W805B, KDL-48W585B, KDL-32W706B, KDL-42W706B, KDL-42W815B, KDL-42W817B, KDL-50W815B, KDL-55W815B, KDL-42W828B, KDL-42W829B,...Today, 04:13 PM -
Hi everyone!
Trying to repair A1534 2015 macbook. The keyboard and touchpad was liquid damaged by coke, but the MLB has no signs of corrosion. The laptop successfully turned on, but missed a display flex. Replaced keyboard, touchpad and display flex, but still no image on the internal display (no backlight as well). When connecting to the external display the laptop works just fine (I have an image).
It seems like internal display is not recognized. I tried multiple known-good displays and display flexes, the outcome is the same: no life on the display.

Hi again guys. I have this motherboard that won't show display even tho it was doing it yesterday. I think something could've past away in the circuit.
I'd appreciate if anyone who is used to MOBO LCD voltages and circuits could enlighten me since this is the first time I have to deal with it.

Hi, this is for troubleshooting and, hopefully, repairing a Delta Power psu
that is still quite new, as it worked OK for some months until it failed.
At the time I was not into power supply electronics; it was put
aside and a new power supply installed inside the computer. Also at the time
power supplies were half the price of today's.
On the PCB there are a D339 and 7500B chips.
I have found that schematics with these 2 chips (see included file).
Does it represent the actual circuit of the MAX-500ATX, I cannot tell.
Some measurements,...06-05-2024, 03:34 PM -

I started troubleshooting this Razer Blade 15 laptop DA560 motgerboard a while back, due to some shorted 19v, 5v, 1v power rails. I fixed some of components and think 19v rail is good, 5v rail is good, 3v is better but not all way i think, and 1v is still bad. At this point the diode reading on these rails are 19v - 0.032v , 5v - 0.167v, 3 - 0.63v and 1v - 0.005v .
When the rails when down, I went down different rabbit holes and seeing chips getting pretty warm on thermal but not blazing hot. Yet there were not any caps or any small components getting blazing hot. Example is EC chip,...06-06-2024, 11:35 AM

Hi, I have quite a lot of GTX 1080 boardview cad files that I found somewhere ages ago, but none of them are close enough to the layout of the card that I have.
There's a sticker on the card that has this on it:
Strix GTX1080 A8G Gaming D212 062820 02365 YV09M2 A04
Has anyone got a boardview for this please? I have a short on the 1V8_AON rail and the FBVDD rail (not the GPU causing it) and using a half ohm device is helping me get closer but I need to see where some vias go to.
