            Hello

            I ordered an new mainboard.. today it arrived only problem is it has the wrong firmware it is an Toshiba,
            So i tried te swap the flash ic, No result.
            I swapped back the ic again. What i did next is replace the defective part from the good board into the bad board, Result still no difference
            So ive been thinking since the board whas struck by lightning the 12V on the mainboard most be bad ?

                Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                by Tynan Dill
                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.

                Assuming...

                Sceptre U550CV-UMR 4K LED, Bad Caps on Main Power Board?
                by Dani_2024
                Hi and thanks in advance for any input you might provide!
                I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
                Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

                Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                Microsoft Surface Pro (5th gen) model 1796 - no power
                by PantherDave
                Hi all!

                I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

                I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

                Asus Z97-a power cycle, no boot no cpu voltage
                by meraklinetx
                Hello, I have an asus Z97-A motherboard and it doesn't start which was working properly before, the problem isn't related by ram, ram slots or psu (I changed all and nothing work), the exact problem is when you switch it on , it starts and after 1 seconds (no boot or display picture) it's off and then on cycle continuously until you power it off from psu also it's responding to the power switch for turning it off if you keep pressing it 3 or 4 seconds (power button pin has 3.3v) , also when you start it with eatx 12v socket connected this is happening (power cycle also all voltages are resetting...

                Acer TravelMate P214 - N19Q7 main power rail shorted to ground
                by mkdj
                Dear all,

                I have taken out the motherboard of a Acer TravelMate P214. There is a short to ground on the main power rail (19V). I don't have the schematics or boardview for this board (DAZ8IMB1AA0 REVA). But I have found 4 MOSFETS close to the main power rail : 2 N-Channel and 2 P-Channel.

                I have checked resistance across each of the 4 MOSFETS. I have the following readings:
                Both N-Channel Mosfets: nothing odd

                P-Channel MOSFET number 1:
                source - drain : 117 kOhm
                source - gate: 96 Ohm
                gate - drain: 117 kOhm

                P-Channel MOSFET...
