    Re: Viewsonic VG2030WM No Display

    I removed D60 and it tests ok out of circuit. I then removed C61 and it is shorted.

    I checked C20, C21, C60, and D10 and they all seem ok (in circuit).

    I am looking for a replacement for C61 but there is nothing stamped on it. How do I find a suitable replacement? I have some other scrap boards that have similar capacitors on them that look to be the same physical size but they are unlabeled as well. Will any similar cap work?

    Thank you.

        Looking at the datasheet for the AAT1164C, it appears this is a 1 uF ceramic cap.

        For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

        Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

            I did some research and one of the boards I have laying here has some 1uF caps as well as some other various sizes. I desoldered one of those and placed it into the monitor and VOILA!! It is working!!!

            Thank you very much for all of your help and input. It is greatly appreciated and this is an excellent forum.

            Thanks again!!!

                    That's how I do it anyways. Seems to work every time - just match the size and it's all good.

                        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...

                        Hi all!
                        This is my first post and also one of my first "deep dives" into electronic repair. I'm used to doing basic tasks with computers, like SSD/CPU replacement, thermal past re-application, etc. So here's the story...
                        I have a MacBook Air M1 that I bought to repair (I know, I'm weird; though I'm a CompSci major and want to learn more , and it will not display anything on the internal display. I have verified that there's no backlight, as I booted the laptop and shined a flashlight on it and there's no display; it does completely boot up, and shows fine on an external...

                        Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                        Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                        Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
                        by ohren
                        I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

                        I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

                        The models launched in 2018 and 2019 respectively....

                        LG 60PK550 Logic Control Board EBR63450301
                        by Yanleb
                        Hi all, I just want to share the repair of my 60PK550-UA TV set.

                        The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.

                        But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.

                        All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
                        C57: 3.30V
                        C61:...
