    Laptop freezes, sometimes no picture. POST every time with 4GB additional memory but still freezes in the windows.

    Philips 55 oled 804/12 red light blink
    by djordje
    Hello all,

    I have Philips Oled 55 (804/12) with black screen and red light blink.

    I have opened TV and tested voltages based on similar oled topics, on power supply board i am getting ps_o/f 3.3v and 5v for t-con_o/f while panel_o/f is 0v. And i get black screen.

    Also i have done self psb test and i am getting on psb +12V_t and also + 24V for panel. (Measurements on dmm are + 12.3V fot t-con and 22.4 for panel)

    When i power only psb and tcon with 4 ribbons for panel i only get black screen.

    My questions is what should i do next...

    LG 86UK6570PUB 3 Red Blinks
    by ChattFix
    Hey Everyone, I have an LG 86UK6570PUB that wont turn on. Power light blinks 3 times. Tested voltage from power supply to main board and it is sending the correct voltage. When testing LEDs I have 1st strip at 210v 20mA, 2nd strip goes from 208v 20mA to 214 40mA. I'm assuming the LED strips is the issue. Anyone seen this before or can point me to something else to check?

    Lenovo Legion 5 (15ITH6H) kind of boot loop but not sure
    by Stefano Crivellari
    Hi, I wonder if anyone can help me fix my Lenovo Legion 5 (15ITH6H) laptop. Basically, after a windows update the computer would not boot anymore. When powering on the laptop the screen has no backlight and nothing would show up, using an external monitor did not help. However, the laptop would still spin up the fans and turn on the keyboard backlight. The keyboard backlight intensity function key would work and the power button led and the charging led are also working. I've tried every possible combination of key press and power button hold down time but did not change anything. At this point...

    Asus FX505DY - Battery not charging - BQ24780S
    by Iherduleikgemz
    Hello everyone

    I have been working on this laptop mentioned in the title, it initially had a shorted capacitor. After I replaced it, the thing started working again, but there is still another problem. The laptop was running off a charger, the battery was reporting 96% charge... but when I unplugged the charger, the laptop died. I've measured the battery voltage - 0V. I think it is locked. (Screenshot from batterymon, below).

    I've ordered a new 3rd-party battery, but I think there's something wrong with it too - the laptop boots, but the battery isn't charging. Also,...

    Replace 25V cap with a 16V in a portable speaker?
    by Paxman_Swede
    Hi!

    I posted a thread about identifying caps of my Zoom 9000 guitar effect where I mentioned a JBL speaker I'm trying to help my friend with. I haven't gotten any answers to that thread but I have a question regarding the cap in the speaker, so I thought I'd ask it separately.

    The cap is marked 100uf 25V. I have found a set of caps on Amazon that I think will cover the caps of the guitar effekt but it doesn't have any 100uf 25V. It does have a 100uf 16V though. I'm pretty sure I read somewhere on this forum that 25V can sometimes be replaced with 16V...but I can't find...

    820-01700 not booting, 4V PP2V5_NAND_SSD0 but 2.5V when the machine is off.
    by xdever
    Hi all,

    I got a 820-01700 of a friend that doesn't turn on. I read that a typical issue with these boards is the TPS62180 generating the NAND voltages, so this is where I started looking. Sure enough, PP2V5_NAND_SSD0 is 4V when the machine tries to turn on (I try to determine this by measuring PP2V5_NAND_SSD1, which is 2.5V as it should in this case. The PP0V9_SSD0 and PP1V8_SSD0 power supplies for the SSD are on at the same time when PP2V5_NAND_SSD0 is 4V). The extremely weird thing is that when the machine is off (PP2V5_NAND_SSD1=0, PP0V9_SSD0=0 and PP1V8_SSD0=0), PP2V5_NAND_SSD0...
