Re: Acer v203HV turns pink to white display
The problem sounds like a faulty matrix board. Perhaps some element under voltage is changing its parameters, I would check the elements on the board by heating or cooling locally. You may be able to find a faulty one.

Re: HP Pavilion 15-e029ss dont pass bios
Include in disassembled form .Remove the motherboard, leave the processor and memory. Connect only the display.
I had a similar problem due to a malfunction of the card reader chipLast edited by kiwin; 05-29-2021, 12:58 PM.Leave a comment:

Re: Acer V3-572g problems
On the bios battery, how many volts? Try to unsolder it and briefly close the contacts on the motherboard. Try connecting an external monitor.Leave a comment:

Re: BAV70W dios replacement
For further repairs, you can temporarily put a diode with VBAT on VRP5V0A_VIN to supply power to the PWM of the standby power supply.Leave a comment:

Re: Acer A515 Not Charging
You have a broken power connector. It has 3 contacts. ++19 volts /GND and AD_ID. The AD_ID pin is not triggered in the connector. It should short to GND.Leave a comment:

Re: HP Pavilion 15-e029ss dont pass bios
You need to try to remove the hard drive, DVD, disable the touchpad. How did you flash the BIOS? A programmer?Leave a comment:
