AT2005B psu modification

Re: AT2005B psu modification

Thank you for your help, I traced the circuit a bit more around the AT-2005B, hope it helps.
This psu has sense wires for 3.3, 5 and 12v, what do I do with them if I increase the voltage?

Any help?

Re: AT2005B psu modification


This was my attempt at tracing the connections on the AT2005B.


PWM chip.


Output caps, they're all 10v, except on the +12v rail it's a 16v cap.


Funny how the PSU doesn't mention -5v but on the previous attachment there is a white cable labeled -5V on the pcb....

Hi, I am trying to modify an old ATX power supply with an AT2005B PWM controller to output a higher voltage on the +12v rail.
I attached an image file I found on an old thread from another forum, and my question is if I need to lift pins 2, 3, 4, 5 and 6 before soldering those pots.
Will it also increase the +5v rail's voltage? And why?

Thanks for any help I can get....

Re: 50+50 pin TTL lcd?

I want to use it with a universal LCD controller with TTL output, such as a VS-TY2662-V1, but I'm confused about the pinout.
Could it be that they have the same pinout and the second cable is there just for redundancy?

Re: 50+50 pin TTL lcd?

Can anyone help? I really need to know if I can use a VS-TY2662-V1 board to output to this screen but I had never seen a TTL screen before. Datasheet doesn't help one bit.

Re: 50+50 pin TTL lcd?

Mine is a CLAA150XG-01, datasheet says 45+30 pin, but my screen has 50+50, both connectors are the same.

Re: 50+50 pin TTL lcd?

I've seen a CLAA150XG-08 on ebay that has only one of the connectors, is it safe to assume it will work with only one?
Is the 50 pin connector the same on all 50 pin TTL screens?

Hi, I took apart an old LG monitor and it has a ChungHwa CLAA150XG, the panel connects to the board by two 50 pin ribbon cables and the only LVDS to TTL converters I can find are for one 50 pin cable only, will it work with only one cable?

Hi, will 10uH be enough to charge a 12.6V battery at 1.5A from a 5V input?

Hey, I have 3 laptop LCD screens laying around so I have ordered an LVDS controller with the appropriate cables, I still haven't received it yet.

I have each screen's inverter, but I only measured the voltages input into the inverter on one of the laptops with a Samsung LT150X3-124.
Pins 1 & 2 - Vin
Pin 3 - 5V
Pin 4 - 3.3V
Pin 5 - 4.4V
Pins 6 & 7 - GND.

The screen controller I ordered runs on 12V, I don't know if the controller already has 5V/3.3V regulators (it should because the panel voltage is configured with...

Re: Cannot read cFeon QH64-104HIP bios chip

To make sure the problem isn't the SOIC8 clip I desoldered a W25Q64FVSIG from an old tablet and soldered it directly to the adapter that came with the programmer, it still couldn't identify it or write anything, it was already empty.
Then I saw a 25P05AV on an old IDE hard drive and to make sure the problem isn't the 1.8v adapter I tried that too and it still couldn't identify or read it, reads always 00 00 00 00.

Re: Cannot read cFeon QH64-104HIP bios chip

I tried every combination, I think this programmer is dead.

Re: Cannot read cFeon QH64-104HIP bios chip

I think my programmer is not working correctly, I tried it on two other chips and it can't identify them, and reads only FF or 00 but Windows recognizes it and I hear the new device connected sound when I put the clip on the chip.
This is my second CH341a that stopped working.
Does anyone recommend getting an EZP2010/13 over another CH341a?

Hi, I tried to read my laptop's bios chip with a CH341a but there is nothing similar to QH64 to choose from the software's list, only 25Q64 but that didn't work and the auto-detect couldn't identify the chip either.
What could be the problem?

BIG THANK YOU TO ALL WHO HELPED ME!
My tablet lives again.
Thank you thank you thank you.

Re: CH341a and logic level converter

I'm using the recommended 1.8V adapter, I didn't notice I had to put the clip on the latch's side, opposite of the ch341. It detects now, thank you.
