Re: Mainboard problem Laptop Lenovo Ideapad 3 15ada05
I looked more closely under a microscope and the board is a mess. The mainboard from my computer had some ddr related problems. I ordered a "new" mainboard from aliexpress and the one that i got is a complete disaster. It has some missing components, i think the EC was changed and it is not welded properly. In the meantime I reflowed the ram on my board and everything works fine. I opened a dispute and sending this board back. I was just curious what can cause this symptoms cause the board was working except that fan...

Re: Mainboard problem Laptop Lenovo Ideapad 3 15ada05
Thanks for the reply. The mainboard has display, the bios was reflashed with a good working dump. It is a mainboard related problem, with another board everything works great. Can it be a CPU problem?Leave a comment:

Mainboard problem Laptop Lenovo Ideapad 3 15ada05
Hello! I have a problem with a mainboard from a Lenovo Ideapad 3 15ada05.
The problem is that the cooling fan is always on full speed, It doesn't recognize the battery and it is not charging it and the keyboard has only partial functionality, many of the keys don't work.
I tried a new bios update but that didn't changed anything.
What could be the problem with it? -

Re: Panasonic TC-P55VT25 Vertical Green Line
I have just tested it on HDMI and it does't make that line.
in my opinion that rules out the t-con. It remains only the mainboard.
Have you ever seen this kind of defect?Leave a comment:

Re: Panasonic TC-P55VT25 Vertical Green Line
I have the same thin line issue with a Panasonic Tx-l32s20e.
Normally it is a thin line but when i press the menu button the line does not remain.
It could be a panel issue or t-con board?
