      OK, you can use that but I recommend a fixed 10X probe. If you switch it to 1X you risk damaging the scope.
      I use my 1102E to test plasmas too.

        I have a good set of probes with 1x ref and 10x. way better than stock that came with my scope...It locks in the 10x setting

            On the Y-main and X-main, yes, they are isolated from the mains power.

                Re: This guy has an RCA 42PA30RQ

                Scope:
                - CH1 ON, CH2 OFF
                - DC coupled
                - BW limit ON
                - 10X probe
                - 100V/div
                - 10ms/div
                - Acquire mode: Long Mem
                - Set trigger to a few volts above VSCAN (will be indicated on PDP)

                Probe:
                - Set to 10X. Do not set to 1X.
                - Probe topmost lead of C5035 on Y-main. It's a poly film cap near the outputs to the buffers. Topmost as installed in TV.

                Use the Rigol's screenshot feature and upload a pic of what you see when TV is powered on.

                              Leave it in the settings I said. You are seeing "essentially" zero.

                                            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.

                                            Asus Probook P5440UF-XB74 power issue

                                            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...

                                            Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture

                                            I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                                            I ordered a supposedly ‘new' Tcon board this time, and

                                            Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply

                                            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...
