Hello,
YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo
I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.
On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.
I also changed the screen because the PC fell and the screen was broken.
I changed the battery with a new and original battery.
I also had corrosion/oxidation on the... -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
I want to fix a Lenovo Legion 5 15ACH6 laptop, the laptop turns on but the screen is black, GPU and CPU are cold.

Hello everyone,
I have a Lenovo IdeaPad 5 15ALC05 NM-D701. When I press the power button, the fan comes on, the power button flashes but the screen remains black. The device has a current consumption of 0.7A. I only have a BoardWiever for the device and no schematic. I have already tried to rewrite the BIOS, but the behavior is the same.
I have checked all voltages and everything fits:
PU1901 LV5028RPC - works
PL6202 -5.08V
PL6201 - 3.32V
PL300 - 0.77V
PL2101- 1.8V
PL1901 - 0.77V
PL1902 - 1.8V
PL1903 - 1.21V
PL5601 - 1.10V... -
Hi all,
I have a question about a Lenovo board (HS45Q - HS45S (NM-D891) - later I will update this with the exact Lenovo model number.
I'm not experienced at all, but I managed to get this laptop from someone that needed to get rid of it. He had a water bottle in his bag which started leaking.
The initial problem was that it didn't show anything on the display, but it did show stuff when I connected an external display.
I saw water damage around the lcd connector. After cleaning and checking all wires and lines, somehow during testing I managed to blow up IT8227....03-16-2025, 02:41 PM
