i search those , i want to repair some of my old video games consoles like my sega-cd (i kill it all by my self .....with a nes plug ! :smt022 ) can somone link me to thes type of sites ? thx!
If you don't know how to repair them, don't. Get a proper electronics engineer to do it. Its all fairly basic stuff (especially blowing voltage regulators like you did).... but you could do more harm than good if you don't know what you're doing. I'm not one for - take this out replace it it should work. Don't do something unless you know WHAT you are doing and WHY.
Buy a few from ebay. One to replace and another one to get parts from and test for faulty capacitors and resistors. My first Genesis had a loose capacitor, because of that that console barely works on me.
yeah , that's why i want a web site that say how to do it.... clearly explained , sure . i know what goes wrong , i 've repaired all lot of things with websites. but i never saw sites that say how to repair sega cd. that'S why i'm asking them here, btw: how do you think a reparator fix something for the first time ? he learn by someone helse ....
If you have a sound knowledge of repairing, a good basis in electronics, not just "fluke" repairs, then you'll KNOW what you've done. You plugged the wrong PSU in. You blew the voltage regulator. Hmm, what do you think you have to do? There may be fuses that you blew too......
BTW, the reason you haven't found any websites: Testing / repairing a games console can be tricky. Sometimes, you need the repair manual and circuit diagrams. Repairing consoles needs a sound background in electronics. For the above reasons, this is a job for a qualified technician. Qualified technicians won't want to give away the answers on a web site because: 1. They charge for their services. They don't give away the info on how to do it 2. It needs a qualified person. If you tell someone that the voltage regualtor has gone, and they go and blow something else due to not using a heat shunt, they might try and moan at the person who told them. For that reason, the information I provided is to be used AT YOUR OWN RISK!!!!
hey , im talking about a dead sega cd ! what the hell do you think he will do if i can'T fix it? he will not work. so what can i loose? hell , i just whant to know which pats i must buy! wich things should i need...when you know that , an you know how to solder something , and have a little bit of experience you can do that. :toimonster: anyway , i foud things for 32x.... too bad for me.
Well, you could turn a simple repairable fault into an irrepairable fault! But... its up to you. I've told you why there are no sites explaining how to repair them. Also, there are hundreds of faults, and lots of faults can have lots of causes. To a typical gamer, the fault will be "Doesn't Turn on", "No picture but power light comes on", "No sound" etc. To the technician, the cause will be blown voltage regulator, logic selector stays high etc. They don't have time to put it in layman's terms - "Black square thing has gone. replace it"
well , thanks.... but those technicans demand so much money to repair something ... i think ill just buy a new one. damn! all this made by myself ! i was able to play it only 2 hours :smt022 one minute of silence , (one minute later) and everyone says, shame one me! and after , i return to the hunt! :smt043 well , i guess i fell sleepy. :smt043
Yup, with most consoles getting a new one is the best (cheapest, easiest) option... give it a go if you want though, if you're just going to leave it as non-working.
You played it for 2 hours with a faulty adapter? Wow, I'd think that it would've blown in an instant - NES is AC and SCD is DC right?
I'm not sure if NES is actually AC, but the adapter surely has the wrong polarity. I wouldn't say for him to get a new console, 7805 voltage regulators are about US$0.40, I believe the SCD uses 3 of them. It may also use a 7812.
no , i played it with the right adaptor for two hours and after i tought a clean-up for my consoles area would be necesary ( i don't know why but every time i have a new video game console , i feel the need to clean the room .... :smt043 ) but i have a lot of dc adapter , and it could be really confusing , and i was a bit tired , so, i , really tired , plugged my nes adapter in my sega cd .. always after the clean up , i check up every consoles i own ( i start them to view if i forgot to hook-up something.... so...i started from my snes to finally try the last two one ... the sega cd and the nes.... i openned my sega cd ... it light up ..... but imediatly after light off. so i tried to restart it ..... but nothing happen.... so i check the dc adapter ....YIiiiiiKES! that was my nes adapter .! damn.! so i switch the real nes adatper with the false that was hooked at the nes ...... i finaly hook the sega cd dc adapter on the corect console..... but it never started..... :smt022 yeah , i think i'll try to repair it . if im able to repair it , i'll certainly not buy a new one . i have nothing to loose and everything to gain. if everything work corecly , i save bucks . if it doesn't work i'll just do like i was supose to do, buy a new one...it will be cheapier than repair it from a proffesional .) so what i need exacly ? can i have pics of what i need to do ? yeah , i'm really not a pro for thoses things ... but try it cost nothing! :smt033 thx.!
By all means, keep the old SCD if you decide to buy a new one - in case the lens ever wears down, you'll have an easy fix (when most CD-based systems 'break' its a problem with the lens)
