    A Central Air Heating Element, A PID and a Sauna
    by JayPoorJay
    What could go wrong...?

    I'm not sure if this is the right sub category or even the right forum but here goes,,,

    I'll just dive right in. I want to see if it's possible and what it would take to use a PID Controller (or 2) to run a central air conditioning heater element (the kind that goes into an air handler) and a small blower fan... The application is a DIY Sauna... Am I nuts? Mean, these components could be had for around 100 bucks.

    What do I need to be thinking?

    Of course I will go to Vevor and order one of their 200$ sauna heaters so I...

    Asus X512D(A) pulsing 3.3VA_EC.
    by f-bone
    hi guys,

    this one only has a boardview and I can see 3.3VA_EC pulsing (as is PU8701 3VAO+) along with the power led. I injected 3.3V on that line but nothing warms up (0.01A draw) except the EC slightly which can be normal.

    I tried another bios incase it is related somehow and a 51225C (dont have rt8249C in stock, [url]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/78627-richtek-rt8249c-equivalent?p=1637735#post1637735[/url]) with pin19 isolated (and also connected) - same result....

    Acer Nitro 5 LA-H501P Not Charging, Not Powering On
    by Growtopia Jaw
    I have an Acer Nitro 5 AN515-54 no charging indicator and not powering on via AC. Battery is totally dead (0V) and I'm in the process of getting another battery that at least has some charge left in it.

    I have no idea where to start so without plugging in battery and plugging in AC, I measured main voltage rails with my analog multimeter. i've also attached boardview and schematics for this motherboard.

    Hi guys.
    I purchased used low price Surface Book 1, expected to work fine but was wrong.

    Seems like a serious issue.

    lenovo gs440&gs540 nmc511 rev 1.0 ram disable
    by madsay
    The schematic and BRD of this motherboard are available. According to the micron ram schematic I have, it is necessary to use 010 to make it dimonly. Even though I did this, the onboard ram still displays the image. I wonder where I am doing wrong in this process? Also, do I need BIOS to disable RAM?

    Sorry, I'm writing with google translator.​

    Power amplifier SMPS IGBT keeps blowing - Artcoustic PDA1000
    by mikkele86
    hello.

    I have two power amplifiers, both having their IGBT blown on the PSU.
    The original mounted IGBT where marked with [B]IRGB20B60PD1PbF [/B]and the gate driver is a [B]IR2156STRPBF[/B].

    I looked at mouser and digikey and could not find any available [B]IRGB20B60PD1PbF [/B]and somehow ended up using a Bourns [B]BIDW20N60T[/B].
    I replaced the gate driver, the gate resistor and both IGBT. But as soon power is turned on, both IGBT shorts out completely (gate, emitter, collector) and the fuse on the AC line gets killed.

    So I though i missed a capacitor...

    Asus ROG G751JY No Power (Short)

    Hello everyone. I have an Asus G751JY motherboard that will not power on.
    - Charger has been tested. Reading 19v when connected to wall.
    - DC/IN has been confirmed to be good. Reading 19v
    - Everything circled in first pic is showing 19v
    - I tested random components and found 5v and 3.3v producing.
    - In diode mode all these mosfets (pic2) are showing like a 0.4 voltage drop..But when i read the inductors they are triggering a beep from diode mode and showing short.
    - I took readings from.the inductors in resistance mode and they are all 6.5 and the 6.5 follows...

    by Vlad713
    Hello everyone,

    I am struggling with an issue on my LG TV, as mentioned in the title - please see the attached photos.

    The display / panel has been replaced in March 2023, under warranty - right before expiring after 2 years of use - due to a bunch of dead pixels.
    Then in a few months the purple / pink line started showing up, however the LG service said that this is not covered by any warranty, anymore, since the original one has expired.

    Recently I have just asked a repair firm to have a look and they have said that the panel needs to be replaced,...

    Dell 15 5566 LA-D871p
    by Sergio Kub
    Hello
    I am repairing this board and I encounter the following situation: It does not turn on and does not have the primary voltages, +3VALWP and +5VALWP and the ICs also do not have the EN_3V and EN_5V enablers, which come from the SIO ALWON signal through the PR121 arrangement. SIO has 3 VLP and does not generate this ALWON signal.
    The question: is SIO bad?
    If anyone has had this experience and can help me, I would be grateful in advance.​
