I have the NM-A281 with fried the KBC.
I also noticed that the SY8206BQNC [pu401] that provides the 3,3 V gives 3,83V at +3VLP and at +3VALW.
That must be a good reason why KBC was fried.
I removed the KBC and measured the parts that regulate the output in my opinion - the PC411, PR407, PR444 and the PC403 are ok.
Also I replaced the SY8206BQNC but i get the same output that is too high.
I placed a new KBC and also noticed that U13 burns hot I guess by the efford to regulate down as I get 3,07 & 4,94 at the ouput [no short at output].
Any suggetions... -
Hello all,
I have this dell g15 Ryzen Edition 5515. Board GDL56 LA-K453p. It had liquid damage when i bought it. Cleaned it up really well and then used thermal camera to see what got hot.
Found the power pdw1 and pdw2 under the graphics card were getting hot. Pdw2 was hottest, i had a similiar chip on another board so i put it on this board.
The other chip is now hot as well, which it was to begin with.
Thats the problem as i dont know what to call it, like is it a mosfat? or what?
I will attach a picture of both the boardlabel and of the area with the chips.... -
Hello, can someone help?, this Acer Aspire A314-21(DA0ZASMB8D2 Rev. D), flashing/flickering LCD when brightness set to full, sometimes it changes to green, red and white screen, I think there is problem with backlight control or LCD power, I have DA0ZASMB8D0 boardview and schematic, but not real D2(14 inch), but component look similiar, I don't have osciloscope to measure voltage ripple to lvds route, but I highly suspect it must be it, can someone enlight me?
