Good day!
I have a customer's laptop — Acer Nitro 5 AN515-54 (EH5VF - LA-H501P). It has a display on the external monitor and it's working fine, but the issue is NO display on the internal screen. I already replaced the eDP cable and checked the LCD connector pins.

Here are the voltage readings:

• Input – 19V (stable)
• +LCDVDD – 3.3V briefly, then drops to 0V
• EDP_HPD – 3.3V briefly, then drops to 0V
• PCH_BKL_PWM – 2.2–5V briefly, then drops to 0V
• EC BKOFF# – 1.8V briefly, then drops to 0V
• PANEL_OD_EN – 0.3V

Is it possible that the EC chip is corrupted or damag...

This power supply is 30v 5amp. Problem is when turned on after about 3 minutes voltage starting to decrease slowly. (like - 5.8 > 5.7 > 5.6 > 5.5) can't see any damaged component or dry solder joints. Checked main 2 transistors with multimeter. Reading seems ok. Tried changing potentiometers(both coarse and fine) still the same situation. Can any one help me to troubleshoot? What voltages to check? Any ideas helps to fix this. thank you.!

has anyone ever had to replace the SVC chip on original xbox? 1.3 version
i have fully recapped main board and eliminated psu with working original
and checked the print for corrosion caused by leaking clock cap ect

box will start up fine when the SMC ic is frozen with freezer aerosol spray
but otherwise it just wont start,
sometimes the fan will spin if you keep holding the power on button
but it wont start up
i would value your opinion thanks...

Hi,

I am fixing the charger (UC18YKL) for a Hitachi battery drill (DV18DCL2) but, as it charges Lithium batteries, I need to know the correct replacement device for the blown (smd) FET2.

As I have spent many hours trying to find a schematic for this DV18DCL2 charger without any luck, does anyone know where I can get one or a parts list?

Thanks in advance for any help,
Rob
