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?

by f-bonehi 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....Today, 09:10 AM -
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.

by paparazzo79Hi guys.
I purchased used low price Surface Book 1, expected to work fine but was wrong.
As you can see, missing key to deattach, which was sold like this.
While I was using the laptop out of a sudden it started to behave like I was touching display.It started to scroll down vertically without me touching laptop at all.
Seems like a serious issue.

by madsayThe 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?

by mikkele86hello.
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...01-06-2024, 06:45 AM

by Vlad713Hello 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,...Today, 04:14 AM -

by Sergio KubHello
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.01-09-2024, 12:03 PM
