Sega Genesis VA2 Model 1 Non-TMSS Freezing and No Sound after a failed recapping.

Tell me why i should never recap consoles using other caps from other consoles on what you told me here? I did it and i've never had a problem. I used capacitors from dead Fat Gray PS1 Power Supplies.

 

Electrolytic Capacitors are chemical and they degrade over time. That's why.

 

Old caps degrade is quality over time and will no longer meet the printed rating. This is especialy true of caps from the 90s to mid 2000s.
And you need to use caps that have the same rating, which im sure the ps1 power supply does not have the same rated caps as a sega genesis.
it may work initially, but wont for long.

 

Hey GoodToFu, I got my VA3 Model 1 back now. But can you still fix my VA2 if you can?

 

Also my VA3 doesn't freeze and it has more bass than my VA2. But fix it if you can still.

 

1: I wanted to use caps from my VA6 Genesis because they were good since the ones on the VA2 were bad.
2: What does that mean "equivalent of pissing your pants to keep warm.".
3: I understand that the 7805 is supposed to get very hot.
4: Thank you.

 

Capcitors will fail eventually with age. So re-using old caps from other equally old equipment is just pointless. They will most likely fail on you soon. Maybe not next week, it could be a few years if you're lucky, but you should have used new ones that would last another 20 or 30 years.

You are just replacing the caps with subpar components, to get your system working right in this moment, but it won't last. That's the definition of "pissing your pants to keep warm" if I've ever heard one

Edit: But hey, don't feel bad. When I was younger I too reused old capacitors in my projects. Now you know better, so just be prepared to replace these when they eventually fail

 

Like the others have said, always try to avoid using old capacitors if you can. If your living room needed a fresh coat of paint, you wouldn't paint it with 20 year old emulsion right? Same thing applies to electronics. 17 is a young age to start getting into electronic repair, especially if you're not studying it at college or something.
There's alot of skills you'll need to learn, but they are skills that will only develop over time by practicing, and making mistakes. You've learned a valuable lesson here. My advice to you is to start by getting the right tools. A decent soldering iron is a good start. You can get decent Hakko 936 clones on ebay for around $30.
Learn to use flux too. It took me a long time to discover how to use flux and let me tell you, it makes a difference. If you want to learn, do it properly. Teach yourself by reading and watching tutorials online. You'll thank yourself later.

Your VA2 is easily repairable by the looks of it. Worst case scenario, its a broken trace and a few missing capacitors. There any many people on this forum, myself included that could fix that up in 5 minutes, so don't worry about it.

 

Okay,
1: I have a VA3 now.
2: I am 17 and i am learning how to solder.
3: I needed to put my VA6 caps into my VA2 because my VA2 had low sound on the TV and had an ear rape for the headphone jack making it super loud and distorted.
4: What is a Hakko 936 clone?
5: Does bad capaictors on a Genesis cause low sound on TV/ and ear rape on headphone jack?

 

Hakko 936 is a pretty good soldering station. If you want to learn to solder properly, get the right tools.
Bad caps can definitely have a negative effect on sound. You should not use old caps to replace with though. Capacitors are cheap, just buy replacements online

 

the only reason why i wanted to fix my VA2 because i had a low sound issue on the TV using RF, and when i used the headphones using speakers, I got an ear rape which means super loud volume and in Sonic 1 2 and 3, On the Sega Logo, I get the ear rape when the voice says "SEEEEGGGA" Is it proably flawed audio amp (Sony A1034) on the VA2 or bad caps? And i accidentally burnt my hand with a soldering iron. Should i use gloves?

 

Can you explain the amp and the low sound? Thanks.

 

You don't need to use glove. Just be more careful. I burn myself all the time. It's part of the hobby.

 

UPDATE: Before i ship the board in a box to GoodToFuFriday, I uploaded a video on YouTube for him and everyone to prove to you it freezes and i have more photos of the VA2 board:

Dude you're like super heavy handed with your stuff, no wonder it doesn't work xD

 

Yeah he is treating his stuff like garbage. I'm not surprised that it doesn't work either, if the same approach was used when soldering. Of course the sound doesn't work when the capacitors are still missing entirely.

Best of luck to GoodToFuFriday.

Hope you will get it working in the end

 

What does super heavy handed mean?

 

How am i treating my stuff like garbage? I was fast because i was angry that my VA2 was broken. And thank you for saying Best of LUCK for GoodToFuFriday. Also i used caps from a shitty Model 2 VA0 since i don''t care for the Model 2 and it still didn't work.

 

VA2 has bad sound even when it works properly. (but yeah it's supposed to be too loud not too quiet haha)

 

I have a VA3 and it has good sound. But doesn't a VA2 have a YM2612 chip. I meant bad sound because the sound on my VA2 was low on RF.
