    Aspire A315 LA-K701P short circuit
    by Scarbs
    Hi,
    I seem to have a short with or without a capacitor. I've removed the power management ic which was above 100 degrees. Short is still present.
    Ideas please.

    TV Samsung UN75NU6900FXZA
    by alfredomfr1
    LEDs TV work with the Power to Main Board cable disconnected.
    If the cable is connected red light no present, STBY pin oscillating.
    I replaced the Main Board 2 times with same result.
    Now the weird thing: With the TV connected and the LEDs lighting up , I connect back the cable to the Main Board, the TV turns off but the red LED light up and you can turn ON and OFF the TV working perfectly until you disconnect the power.
    When you disconnect the Power the TV return to the previous situation.

    ASUS P4P800SE/P4C800-E recap (polymod?)
    by usernameunknown
    I have two P4P800SEs, a P4C800-E Deluxe and all three boards show the same issue: difficulty POSTing (getting stuck on POST code 0D), or crashing under light load (but bizarrely, the P4C800-E is rock solid running Prime95 with a water cooled 4.3 GHz Pentium 4 3.4)

    Should I consider recapping the boards? If so, what caps do I need? Is polymodding these boards worth it?

    Do note I have never recapped a board myself, nor do I own good soldering equipment to do so.

    Elitebook 820 G3 engineering example: CMOS settings lost despite new cell
    by i440bx
    Hey there,

    I got a HP Elitebook 820 G3 Engineering Sample Laptop and I want to use it. Besides the difficult things at the ES-BIOS I have a big problem by saving the main BIOS settings.

    The laptop does not have a big battery because it was dead, but I already plugged in a new CMOS battery.

    It takes about 5min without power and the BIOS settings are lost. Unfortunatly I dont understand why the BIOS settings are only saved with power connected and this is the reason why I registered here.

    As written above, I plugged in a new CMOS cell and checked...

    Smd code to part number
    by esinior
    Hi i have a smd part with probably mark "QO 11" or "Q0(zero) 11" on it, and its package is SOT89, i doubt its KTB1260 PNP transistor, but in measuring with diode mode of multimeter it shows number 1.4 between emitter and collector pins and its not open circuit, and .59 from collector to base and .8 from emitter to base , and these numbers doesn't match a pnp transistor, i couldn't find any part number and datasheet for it, does anybody have information for that part number?
    I've attached pics of this part
    Thanks...

    Dell G5 SE 5505 Random boot loop
    by Andreasbest
    Hello.
    I bought a G5 for my self, at a low price, i knew it was faulty, so the fault is that does random boot loops.
    I tried RTC reset, BIOS update, replaced thermal paste with MX-5, checked fans for dirt, disconnected all flex cables (daughterboard usb, keyboard, trackpad, wifi, m.2, replaced RAM) but still the same.
    This behavior can be a faulty GPU/CPU or if any of these components get faulty the laptop shut down completely?

    When i get luck and enter Windows i see everything in device manager without exclamation marks.

    Any advices or thoughts welcomed...

    TCL 65S450F no logo, bleeping sounds?
    by CapLeaker
    Got a brand spankin' new TCL 65S450F here. Plugged the TV in and it booted up and wanted a firmware update right away. O.k. I guess it did that or not... I got no forking clue. Came back in 10 mins later and the screen is black, backlights on. The Standby light is blinking and every 10 to 15 seconds makes bleeping noises. That's all she does. Tried a factory reset and that must work as I can adjust the volume of the bleeping and it returns to factory volume afterwards. Also tried big black button with the circle right button on the remote and no go.

    EDIT: No bootloop the bleeping...

    Issue with 42 Vizio TV
    by derrickcaputo
    Hello,
    I have a 42" Vizio TV. I hooked my tablet to the HDMI inputs. Everything was fine until the screen went black and now the only input that works on the TV is coax. No hdmi, no component, no rca. I tried hooking up a laptop to the Hdmi port and the computer
    detected the TV model but no image.

    Is there anyone having the same issue? Did you find any solution?
