Great video, Roger.
This was one of very few video games my parents gave me for Xmas as a kid, and I remember it fondly.
Now 47, I still have it stashed away in a box in my wardrobe somewhere.
I think you've just inspired me to dig it out again tomorrow and see if it still works😁👍🇦🇺
Thanks Simon. Sometimes I read messages from viewers that really inspire me. Yours was one. These messages really motivate me to keep at this. Thank you. So happy to bring back happy memories. Let us know how it goes and thanks for your comment.
Always a treat when I see you've uploaded, great repair. Remember this game well from my childhood, getting a sore thumb from the little joystick and asking mum for new batteries all the time 😁
Thanks Skyway73. Happy to bring back some fond memories. Thanks for you unwavering support to the channel and kind words. Hope you are well
Nice job as always, Roger! I've actually seen that "two diode" weirdness before as well, and also had to replace the transistor.
Good to hear. Somebody explained why in one of comments ... sustained reverse bias on a junction maybe? Either way glad I am not alone. Thanks again for your comments!
Funny how video production will change your priorities ("Not a simple repair, Yes!")
Always a treat watching your content mate, much love from Oregon
Ha! Yes I suppose it does. I actually "lose" a lot of videos because either the stuff works perfectly or is so simple to fix that there is no video in it for me. Thanks for your comments.
I had this game back in the day. Made me want to buy one watching this
Good to hear, happy to bring back some fond memories. Thanks so much for your comments
Good video. These videos are really helpful for people learning the hobby. I like your straight forward approach. I think older tech like this is a great place for new techs to start. Simplistic circuits that can be broken down to understandable parts. I can say if nothing else, you have definitely helped me better understand how to test transistors. Keep up the good work.
Great STHelton1 thanks so much for your feedback. The old tech is how I'm learning too, when I first started this I had only a £10 multimeter and I didn't know how to test a transistor. Glad you enjoyed the vid.
Roger is back!!!! Enjoyed as always, hope you are keeping well 👍
I'm doing OK thanks Vince. Thanks for your feedback. I'm sure you are very busy with all your argos returns and that Rolls Royce. You've done some great work on it. I did something similar with a porsche 944 tubo loved the car but by the end was ready for it all to be over.
@@RetroTechRepair I have a love hate relationship with it. Some days after working on it I am on a high, other days I wonder why I am wasting my time!! 😂 Luckily it has a bit of a dedicated following, (not a big following like the return boxes but very dedicated following) so that motivates me to continue. I'm not sure if I would have the patience otherwise. Anyway, lovely to hear from you again. I hope life gives you the time to upload more. I can see from the comments section that others feel the same way about your videos that I do. We all love them!
Oh Vince you are too kind, I'd only have a few hundred subs if it wasn't for you. I'm one of the dedicated roller watchers haven't missed one. Funny how argos returns interest people more. At some point I may rebrand so I don't need to do only retro but over the years I've bought £1000s of retrotech so plenty to keep me going. We'll talk again soon. Cheers Roger
You are very welcome @@WhatHappensWhen
Oops, wrong account😂....Cheers Roger @@RetroTechRepair
Good repair.
14:51 The capacitor replacment at the end means this Galaxy Invader 1000 will now provide endless hours of enjoyment for future generations of children.
Thanks! Let's hope so. Its a fun little game so it would be good to keep it going for another generation. Thanks so much for your comment. I Appreciate it
I used to play a friend's one at school (the white Galaxy Invaders version). We used to play during registration before lessons started and at break & lunch times. One kid had Pac Man 2 and another had one called Space Laser Fight.
This was a *VERY* long time ago!! (1982-ish) 😱😱
Always check your battery terminals first. Then check your capacitors next for correct value and esr. Esr values can be obtained from the internet but generally should be around the 0.46 to 1.00 mark depending on their initial capacitance values.
If in doubt, bin it out..

Thanks guys! I do have an in-circuit ESR meter now. I'm doing a bit more restoring rather than just repair I might recap a bit more often. Thanks for the comments advice and comments 👍. Really appreciate it.
Capacitors tend to be little time bombs waiting to go pop. And when they do, they cause all sorts of electronic headaches else where on the pcb. Be VERY careful of anthing that was made in the late 80's toward the end of the 1990's. It's a well documented story that is mentioned quite often on the Internet.
As a final tip try to use Elna, Vishay, Panasonic (Matsushita), Nippon Chemicon or Rubycon low esr capacitors. They aren't cheap, but are well worth keeping a good stock of.
Hope this helps.
Wayne & Nina
👍👍👍👍👍😊😊😊😊
An excellent point Wayne and Nina! The video disc player I repaired was a good example. I really should get a selection of quality low ESR caps, as you suggest the ESR of my cheap amazon kit is not good. I generally don't use them in anything expensive or important mind you. I'm hoping to move house in the next 12 months to somewhere where I have more room. At the moment I repair stuff in the hall of my flat about 5ftx5ft. Thanks as always for your comments and support. Always a pleasure. Roger
The transistor that showed as two diodes on the tester my have suffered degradation of current gain due to repetitive reverse breakdown of the base-emitter junction. This can happen in oscillator circuits. It is usually a relatively slow but progressive process. The proper solution is to protect the junction from reverse breakdown by addition of a diode across the junction, though this can shift the behavior of the circuit e.g. frequency if it is an oscillator.
Great info! Thanks so much. Learning every day. I appreciate you giving such informative feedback. Very useful. Thanks for taking time to comment.
Thanks for your reply.
The story goes that sometime in the 1990's a certain employee of a Japanese capacitor manufacturer became unhappy with his firm. He therefore jumped ship with another firm, whilst taking the formula for capacitors with him. However, the formula was WRONG somewhere along the line. And it rotted the backside out of the capacitor, making it leaky, and causing pcb damage due to the chemical composition of the electrolyte (which was incorrect)
Anyway, it's all well documented on the Internet for further scrutiny.
All the best.
Wayne & Nina

Wow that's interesting ! I have never heard the bad cap formula story. Totally fascinating. Thanks!
I ❤ watching old things got repaired.
Awesome, so glad to bring a little joy! Thank you so much for your comments 😊.
Really enjoyed that video. As a child of the 80's I fondly remember those games.
Any hints on learning how to solder for a total beginer ?
Hi Mick, glad you enjoyed the vid and thanks so much for taking time to comment. I'm really no expert on soldering so I'm not sure I can help much but maybe just get some prototype board or an old PCB from something and practice. It's actually not at all hard to do a good enough job.
@@RetroTechRepair thanks, I'll give it a go 👍. Keep up he great work BTW
Thanks @mickmerr good luck. A simple soldering stand and iron is probably all you need to get practising. Do get a stand, though, as it may save you worrying where you left your hot iron or worse still burning something.
Nice! I learned something in this, too - testing transistors. That's nice :)
Brilliant! Thanks so much for taking the time to comment and feedback. Very much appreciated.
hi my mate had this the sound of it used to drive me crazy
i un solder the sound speaker in many of the games like this i know they cost money in the past
Haha I'd imagine they got played a lot when new and drove many a parent mad! Some of the later CGL/Gakken games had sound on off switches. You are right they were expensive back in the day, only the richest kids at school had an astro wars. I certainly didn't. That's actually some of why I started this channel, to have and experience some of the things I couldn't do as a child. Thanks for sharing your memories 😊
I have one that seems to cook batteries. They get very hot and drain very quickly. Any thoughts on cause would be much appreciated? Been subbed since your first Galaxy 1000 🙂
First off, thanks for your subscription. It really does make a difference, and I'm grateful. Thinking about your game. I've had a couple of VFD games running high current (I think this might be the problem as the warm batteries that don't last long are probably pumping current through the game). Neither game was invader 1000, but these ideas may be worth a try. One game had a partial short on one of the pcb tracks caused by a solder bridge. So a careful inspection under magnification looking for bridged tracks is worth a try. May also be worth taking a resistance measurement across the battery terminals with the switch on but no batteries in. The end that isn't a dead short is about 7-8 meg ohms on mine with the power switch closed, open circuit when it's turned off. If that all checks out I'd start testing diodes like on the vid. I'm guessing you'd get results like mine in a good game. I've seen failed diodes lead to high battery drainage in a working game. If it is a diode, my puck monster video has an idea how to determine a suitable alternative. I suppose it "could" be a failed cap that is becoming a resistor, though i havent personaly seen this.. Anyway these are just ideas, not advice as such as I'm not qualified to give that. Hope it helps. Stop back and let me know how you get on and tell all your friends as i need the subs! Thanks again for you sub and comments.
@@RetroTechRepair Thank You for sharing your time and knowledge. If I get time to check it over the silly season, I promise to update the results here. Really appreciate all that you do and wish you and your family a Merry Christmas.
Thanks@@GManmcaoidh
Enjoyed the video. What model microscope did you get?
I just seen the other video in my suggested video list, so I will watch that shortly.
Thanks. I didn't want to promote it too much in the repair video as I didn't want to put people off this vid. So 2 for 1 this time!
Yey new video
Yes after LONG wait. Thanks for sticking by me. There were actually 2 vids this time. A separate video looks at the microscope more closely. Thanks for your comments.
wow late video for me (UK here)
UK here too, but didn't want to miss Saturday morning "rush". I'm trying different launch times see it it helps initial views. Thanks for your comments. Hope you enjoyed the video
