Hi everyone, Dell inspiron Duo PIM00 LA-6471P.19v only on power connector and 17v on power switch. No 3.3v or 5v.I do not have schematic so it is very difficult trying to trace power lines. Any help will be appreciated.

Re: DELL INSPIRON DUO: No power, 17volts on power switch.
Well it turned out that upon closer scrutiny, PD22 was missing [don't know how] and PU10 and PQ18 was shorted so laptop works fine now and power switch voltage gracefully dropped to 3.2v. :mrgreen: -

Hi Siddiq. Would you remember how you fixed the short. I seem to have the same problem with a laptop my friend brought me. Thanks. [IMG]

Hi Everyone. First official post so fingers crossed I conform and also manage to get photos to work.
So I am requesting some help from anyone who happens to have one of these motherboards to hand and perhaps a multimeter.
My board has a single row of header pins for all the front panel stuff (have seen others where they are grouped together differently so thats no help) and the two pins for the power on switch had been previously repaired and I am trying to make a better repair. There looks to be pad and trace damage and im happy to relocate the header pin/pins to...06-24-2024, 01:24 PM -

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
