SEGA Master System with No Display - Can I FIX it ?

Sega and their wierd extra components on board that makes it seem like someone has been messing with it already.

Awesome, The memories flowed when it fired up and worked.

Brings back memories that original master system. It should have a game built into that console. Alex Kidd possibly or sonic on the master system 2

Just take the game out and blow it! 😂

Did you remove the green capfrom the end of the desderer because that smells of fish if it melts it's tiny so you may have missed it

fine? i'm tossing caps with more than 2% Vloss (i'm using simmilar tester for caps)... guess it depends on stuff you repair, but i would not call them "fine"...
also i've seen on some relay units 12V that leaked and you cannot really tell it did, only when you took it out it was nasty under it... some of that stuff just flows way too good when it's heated... also some might already tried to fix the thing and they might have clean the board.

YES , the MasterSystem D-Pad was always bad , I switched to Megadrive controllers (they are compatible) ...
what a potentially harmful bodge job you discovered ...

This console also has an RF-Modulator misusing a chinch cable like the SNES does as unofficial standard ( = you cold hack together an adapter the crudest way), nice the old times were !

PAL slo

Shooting Range 😎🤣

Crusty Flux sounds like a good band name.

Is there a way to test a sega genesis ii console even if I don't have a cartrige? I am not much into games but more the electronics part, got a lot of arduinos and stuff so is it possible to build a cartrige just to test the system?

rubbing greene king all over the board haha

well fixed. 👌

When you pulled the chips out you reflowed the solder and also masked any cold solder joints you had. If you do a lot of single layer board repair you should learn how to through hole repair. Everyone is a critic. You did good.

I have the same problem, the light turns on but don’t have image.

Usually on old 8 bit consoles the background changes the black when a large enemy comes on screen because the enemy is large enough to exceed the console's sprite limits and they have to use the background layer to draw most of the enemy.

Nice 👍 one

I really enjoyed this fix and I'm glad you got to relive some kid days. Ain't nostalgia wonderful?

The card interface was to play certain games that were (for some reason. Portability I guess) made on thin cards. These games were much less common (I never saw them for sale), but the fold-out poster that came with my Master System advertised about 20 games that were sold as cards instead of cartridges. Those games always looked simpler and lower quality (based on screenshots) than MS cartridge games.

33 usd = 29 euros. good old times

Yes, if you do power it on without a cartridge, either it will load right into a “Snail” (Maze) game, or you have to press a combination on the controllers like “Down> A & B buttons as soon as an error screen loads, it will either dissolve or flip into “the Snail game”…

For cleaning vents and other holes in cases, I've found a spray with a garden hose works very well. Great job on the restoration! As for those memory chips, one of them, with the MPR- prefix in the part number was the game ROM. The other, as you looked up, was RAM. Position on the board WILL matter because although Data and Address lines are shared between the chips, they will have separate lines for bus arbitration signals, especially Chip Select. This is also why you shouldn't expect every single pin to be continuous on those chips.

If you can find the Master System game called Psycho Fox, definitely pick it up. The gameplay is as original and fun as its name. It's loads of fun. If you ever played the Mega Drive game "Decapattack: starring Chuck D. Head", the gameplay is similar to that, but in Psycho Fox, there are 4 or 5 different characters, each with different abilities and handicaps. And Psycho Fox is way more Japanese in style and setting.

Also, until seeing this video, I had totally forgotten how the 'pause' button was on the console instead of the gamepad. Not too convenient, that. Safari hunt was pretty fun too. More variety than just ducks. There were bats, black Panthers, giant spiders, and all kinds of cute and deadly targets.

Here's a thing you might not know... Electricity doesn't flow through metal, but along the outside of it. This is why thicker wires are braided of as many smaller wires as possible and not a single thick wire, using braided wire increases surface area. It is also why ANY corrosion can cause problems, because it increases the resistance. Anyway, another awesome video, good work mate!! 🤘🤘

Amazing work. Where did you learned to work like that? University?

Old caps just exchange, even if they still seem to be ok

Mastersystem has built in HANG ON game, no game needed!!

which multimeter it is ? can you please share the link ?

Another Great save from the landfill. You have to remember that back then it was 8 to 16 bit processing and really slow, Jeepers that unit is going back to the Ara of just 2 years after I graduated from high school - But I must say Well done Vince...

I had the OG Master system with the secret snail maze game built in. From memory I think you had to press up and both buttons without a game inserted to bring it up. The controllers were also slightly different with a screwhole in the middle of the joypad into which you could screw these dinky joysticks.
We got a downgraded version in the west, the Japanese version had an extra FM soundchip. The rectangular cutout on the bottom of the case with the pushout bit of plastic at the back was where an optional fm synth module to add the capability back was going to plug in but they never released it.
The Japanese enduro racer had twice as much memory on the cart so had more trackside graphics and stages, so we got shortchanged there as well.

Is it not the master system that had Alex the kid built in so when no game was in that could be played? I know it was one of segas but it wasnt the megadrive. I used to have the saturn, megadrive and master system as a kid and loved playing alex the kid. I am thinking of investing in some retro consoles from my childhood so these videos are great I might be able to pick cheap ones up faulty and repair them. I am already watching some nintendo and super nintendos on ebay and I'm tempted by a commodore 64

i think you were remembering the Mega Drive version of Altered Beast

Great job, you are a hard worker, see if you can tell us more about dielectric, the oil that fills the capacitors. All I know is that dielectric oil(?) is polarised with current and it this facility that gives the capacitor its affect on electromagnetism.

somebody spilled surstromming on it

I always thought only the Master system 2 had the built in game.
I remember these when new, they were so far ahead of the times.

I have an NES and a Master system 2 that I bought as an adult due to missing these games.
I even still have my old Mega drive I had as a kid.

Could a capacitor have been replaced with the polarity reversed ( who ever did the recapping might have been a StarTrek fan) ?

You found it later. I was thinking the burning smell could be the Linear Regulator as you have no heatsink on it. Just have to watch those things as they do generate a lot of heat :)

Your genuine explosion of joy when the Sega Logo showed up on the screen just made my day. Thank you very much for your videos!

😮 my grandparents gave me one when I was a child🥹. I cleaned it but I do not play………🤔……LET‘S PLAY🤩 the good old times.

Nice videos but u speak too much!

Hi man. I can't found too much fixing videos for Master System, only yours . One question, maybe you know how to fix this error? : Mine works good , but after 20 to 30 minutes of gameplay, the sound starts to fail, and get even more and more low pitched, until it start to sound like Crunchy. Any idea what is going on, and how to fix that?

“Crusty flux” took her home from the pub one night

A good way to see if a console is recapped is comparing it with different images of mainboards. In the case of the Master System it had light blue and black caps.

Miss the 80s so much.

You really really either need a retro scalier like retrotink, or a real CRT screen. It will never feel right playing these retro consoles otherwise because all flat screens use the same video processing chip and every single one adds an extreme amount of delay in the signal.

I think I have the same exact problem with my Master System. Problem is, I don’t have the knowledge to fix it myself.

I believe the two chips remove are the internal game roms.
