    Is there HDD activity? Try fitting the RAM one at a time.
    I hope the thermal paste is not conductive.

        FIXED - I just want to say a big Thank you for all the assistance - I also contacted the person wrote original YouTube video and he suggested maybe a tiny bit of solder was touching a close by component - I gently scraped with small flat screwdriver the solder back and worked straight away .
        Smali - also suggested clean area around which I did so thanks for that also .
        But thanks for all for suggestions hopefully this thread will also help someone else if run into same problem .
        Thanks all owe you all a beer
        Cheers Mark

                            Photo taken of new capacitors . Have attached image .hopefully shows up .
                            How would I test that voltage , I have a basic multimeter but where and how should I test ?
                            As mentioned Laptop seems to power on ok just blank screen ? Would that be the capacitors or something else ?
                            Thanks Mark
                            Replaced cap as shown on the photo on a Toshiba L305-s5924, issue was worked on Battery but switched immediately I plugged in ac charger. it worked just fine.
                            Thank you.

                                For Toshiba I'll advice you do it this way, use knife to scratch between the two lines to make it five lines.

                                Now place the varactor 330, on the first line and third line, then on the side place another 330 on the third line and last line.

                                Use at least two, or you can make it 4.

                                    use the black printed one if you have any scrap boards the one that theres a letter d on it...
                                    in my experience that kind of caps doesnt work..just try 2 caps only if that's not work add another 2 same kind of capacitor..
                                    i experience i did add 10 pcs of 330uf 5 on both sides

                                        samsung galaxy ao2s very temperamental after screen replaced
                                        by Chrissygizmo
                                        Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
                                        Ive eventually managed to get it on and working but it's very temperamental...

                                        The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...

                                        Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                                        by Ryan.man
                                        Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                                        My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                                        This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                                        ThinkPad P15s Gen 1, NM-C931 REV 1.0 touch screen replaced only works in UEFI menu
                                        by Yehuda170
                                        original screen was BOE NV156FHM-T07 with On-Cell Touch screen I²C

                                        replaced with what was in my stock, which is IVO R156NWF7 R2 which is also with On-Cell Touch screen I²C

                                        now touch screen works perfectly in UEFI BIOS menu & boot menu. but not working in OS, tried windows & linux too

                                        with original broken screen i can see in device manager touch screen in human interfaces

                                        but with the new screen it's not showing in device manager

                                        is it lenovo blocking it? is it driver missing?

                                        I²C is a headache

                                        Hi all, I’ve got a problem I hope someone can help me fixi.
                                        I have a Panasonic TX-48CX350B tv , it powers up ok but the screen is blank, the backlights are working, there’s nothing else though, no picture or sound. I’m not sure what the fault is called whether it’s BLANK/ BLACK/ or WHITE SCREEN I’ve actually came across this before on a similar tv but just ended up scrapping it, I will upload pictures of the boards etc , if anyone could help me I would really appreciate it...

                                        Hi guys
                                        I'm trying to fix this laptop screen

                                        Basically the owner is a computer shop and they brought it to me with two screens. They said the repair shop they use could not fix it, so I thought i would try to see if I am better than their current repairer!

                                        OK so I have the original screen which works but has lines across the bottom quarter of the screen

                                        I have the replacement screen, which they fitted and it worked. They then put the laptop on one side for a couple of weeks until they found a buyer. When they showed it to the buyer, the screen would...
