Don’t know how I randomly stumbled upon a channel where a geordie fixes random things, but I like it! Got yourself a new subscriber here!

The cat's eyes in the IR camera are so funny XDD

Now you just need the other half, the launch tube containing the Javelin missile :) Cool trick adding an off board 3v reg. :)

Excellent diagnostics think the regulator being wrong would have really thrown me, top repair. Enjoyed that thanks.

Wonderful repair, with great deductive reasoning! Well done

Seems when the electronics world started using SMDs they also switched from full part identifications on the parts, to only a few letters or numbers. So locating datasheets gets to be a real problem sometimes. And if you can't see what the part does, it gets even harder to fix things as well. Knowing what parts are sure makes it tons easier to see what a circuit is supposed to do. And than you can locate the problem a lot easier... Thumbs Up for this fix...

Well done, solid critical thinking. Self sufficient, proper Brit.

Night Fox Carrot Vision.... 😄 Nice fix man.

This guy is awesome 👍 love these videos

Great forensic and modification work 😃 Thanks Mick.

You are a electronics magician, great work.

i love how much preparation (or common sense) the seller did. having the screws lay out like that with an arrow is just too amazing to see. i would have expected after seeing the scope in parts in the ebay listing it would be just a big bag of parts and lose ends

We used to use very similar ones of these (not identical) in a big cinema chain in the north east beginning with C... Used to use it go scan a dark cinema screen to see if anyone was recording - had so many complaints as people used to think we were recording them

Anyone who can solder like that is a machine gg man proper happy with this vid good stuff

Great work & video. Thank You..

Having received the unit all in pieces and wrong component installed on the mother board is ten times the work of troubleshooting. But you did good. You have to be a good detective in order to fix such a nightmare. 👍👍👍👍

A beautiful piece of troubleshooting and repair work.

I knew it was a cat video... 😁 Nice fix and good thought process👍

I love the logical approach you take with these repairs, it's like OK I don't have one of those regulators so I've fabricobbled, AKA McGuivered, together something from some stuff I have lying around, hotmelt glued it into place and soldered some wires onto the main board. Outstanding!!! We need far more of your kind in this shit-show of a world we find ourselves in. Keep up the great work.

Very much enjoyed this one. I find the methodical approach rather therapeutic! Thank you sir!

Glad you could fix it. Always good to have more night vision

i always look forward to seeing your video on a Sunday morning and i like the way you explain your repair's i have told a couple of my friends to subscribe to your channel as they like watching things like this the same as me thank you have a great weekend

Excellent work!

Beautiful Work.

Our mate Vince & Steztix Steve will be watching your videos for tips from now on Another very astute fix John. I like your style and mini bodge that WORKED . HALLELUJAH !

The screws in the Styrofoam are in the shape of the Big Dipper constellation with the arrow pointing to where the North Star (Polaris) would be.

Love the Fix 😁 but funny cats looking at cam 🤣

Very nice repair!

Nice work!

I have to say good job fella. Did not think you could of fixed the eye.

Great work.

Great fix 👍

Awesome modification ✌🏻✌🏻✌🏻

Cool night vision camera and interesting fix :)

Nice work, Mick!

I found when looking for where the power feed is, I find what pins are VCC on IC's then follow it back to the battery or power supply, works every time. To find out what an IC that is missing or not legible or have several applications for the same marking. I look up the Data Sheets then compare the components around it that are connected. The reason this works is because some manufactures actually put test schematics or application schematics for that IC in the Data Sheets. Most end manufactures just simply copy those schematics with a slight variation right into their circuits. So if you compare what's on the board to what's in the schematic you can almost always find out what the unknown IC is. Of course you have to have an idea what you think that IC is doing in order to go look for those types of IC's. I find fixing consumer electronics is the ultimate Puzzle Solving Game. Right next to drawing schematics by Reverse Engineering circuit boards with no schematics available to the public. Good job and thanks for sharing. Best Wishes & Blessings. Keith Noneya

Nice repair. Perfectly OK, what counts is the results.

those 1117 regulators are wonderful. I had to do something similar with a 1117 1.8v Great troubleshooting man

Nice Mick. 👍

Great find, I like the repairs where it is more complicated than a visually blown component. Keep up the great work!

Nice fix. Nicely reasoned out. The scope performance itself gives mediocre results. But for $5, less trash, and some good content...good value.

Excellent

incredible

Brilliant

Great video. Have you ever thought of doing a workshop tour or tools that you use etc?

Richtek RT8024 seems to have the necessary pinout too but there are a bunch of different version with different feedback voltages so it might be necessary to check resistor network there.

That gp7u is really unobtanium, and maybe that's a good thing.

Being from the other side of the pond I had to look up Geordie. I can only guess how it sounds. I missed how you knew, or guessed, the regulator should be 3.3 volts.

Nice work Mick. Now you can shoot some clays in the dark from your porch! This one seemed like it was a bit more of a challenge but that methodical & logical mindset is serving you well. I'd like to say it develops with age but I've working on my methodical and logical approach for 50 years so far and I'm lagging behind you already. I don't think I would have solved this one if I'm being honest. But maybe I will going forward, thanks you to. I do have one question though, because I am keen to learn and understand. The regulator that you removed (or that should have been there from factory), I understood from the pinout's you mentioned that there was a voltage 'pass-through' from one pin straight to another pin, is that correct? If so, you're cunning solution didn't appear to cater for the 'pass-through' and if that's true, it leads me to this question. What is the point of the pass through and why did you're fix still work? In your opinion. Or have I completely misunderstood? I'm a big boy, you can give it to me straight up.

Nice fix but you did have me shouting at the screen regarding the screws in the polystyrene, especially when you did the jump cut to them all on the mat- it showed the position of each screw for the case and the arrow was the orientation! But good job on the diag and fix.

Great fix as always! How did you figure out that the circuit needs 3.3 volts?

Nice fix that looks cheap and tacky, thanks for the step by step repair 😊

Now I want to see the train

They should've just used an AMS1117-3.3 like you did in the first place.

Never use NiMH. On four alkaline batteries (1.5 x 4) you get 6 volts, but with NiMH you only get 4.8 volts (1.2v x 4). Some devices think 4.8 volts indicates low voltage and won't power on.

Been a subscriber for a while, i find the videos very interesting, although myself not too good with electronics 😢 I have an interesting and expensive paint thickness meter used once and no longer works 😢 Is it something that would be of interest

There's one singular seller on taobao(mainland china's aliexpress) that sells GP7 series chips(from GP7A to GP7Z). The listing lists them as buck converters. Did ask if they know what make and model those chips are, and the answer is unknown. Would be interesting if I can ask them to mail you some....

Genius

Fantastic vid! I’ve recently bought a NV unit just like this but I’m no way near as knowledgeable enough to fix it like this :( any help?

Not a bad little monocular. I have an eyeclops night vision goggles and they work but the eyepiece is too narrow for my eyes because this thing is a toy so I removed the eyepiece and it's set up the same as your unit, nothing but an LCD screen and modified camera. It doesn't record video but I'm curious if there's a way to add in a composite video out to it.

4.99 alone is a great price for those scraps even if you couldnt fix it.

I have a digital recorder with a faulty regulator as well. I thought I could wire up a 3 legged regulator as you did, with a connection for ground, power in and power out, but there is no connection for the on/off switch?

Where do you buy your lead solder from? Been trying to find some for ages but all I seem to get is lead free.

Just love custom chip id's or when they scrub the marks off so you can't repair causing more landfill waste for increased profits.

Just need big Clive on the job

LCD not LCD display. That's like PIN number and ATM machine.

You are lucky this was not a true NVD. Most of their power supplies are sealed, non repairable units with zero information available to the general public.

Where did u learn how to repair electronics

Night. Vision. Monocular. Dead. No. Power. Can. l. Fix. It

Can you not hear the Chinese saying, 如果愚蠢的人買了這些垃圾，我們就會繼續為他們做 🤔😉
