              i have the same set as this thread
              https://www.badcaps.net/forum/showth...ht=sharp+aquos
              pls tom66 you have answered this
              I think firmware may be corrupt, no reset will cure that. The "I2C" method may be necessary
              how to do that I2C method

                You can probably try this method. On the Main Board search and locate the EEPROM IC. It would be an SMD 8pin IC SOP-8. It will be the 24C64, 24C128 or 24CXXX ICs. (I did not look at the SD for this TV)
                Look up your EEPROM IC number and determine the pin configuration
                Five (5) easy steps
                1. With the TV OFF solder a jumper across the VCC pin and the SDA.
                2. Power ON the TV for 20sec. (You may see an error message on the screen)
                3. Disconnect the jumper at the SDA pin and switch OFF TV.
                4. Remove the other end of the jumper from the VCC pin.
                5. Now power ON the TV, it should perform normally.

                    Re: sharp_lc32ga9e wont power on

                    There is a method to self test the Power Board. Do you know this method?

                        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...

                        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.

                        by GLISIT
                        Hi all,

                        TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                        I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                        A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

                        Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                        by sam_sam_sam
                        I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                        One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
