Genesis CDX - Console not turn on

Hi guys.


Well, this problem was caused by myself.
I opened the CDX to regulate the laser lens, so I was testing it without the top cover but with the metal base below (the your external cap). I believe that part of the plate where the power supply connector is connected, touched metal part and this made him enter into short and now will not turn on anymore.
I think I need to just replace the fuse, but I'm not sure of its values (SOC 2.5A that's what it says in the original fuse), what would your real value?
I can replace with fuse 250V 2A found in PS1 power supplies? Are the only ones that I have.
I know it's not recommended, but I can do a direct link for now if I don't have the equivalent fuse?





All electrolytic capacitors appear to be in order, is there any possibility of some other component have burned/broken?


I really thank you very much everyone's help, since it's my only Sega CD system working at the moment, I hope the fix is simple.


If yours need more details, inform me that I provide

I made the direct link and the CDX worked, I'm really happy.
But I still want to know what fuse value should I use to replace the broken fuse.


That's really exciting and simple solution that I was looking for. I'm almost putting a standard fuse (250V 2A), but I will wait patiently for a response.

 

Its a 125V 2A fuse but it should be a pico-type fuse.

 

Very very very thanks, Sephirothkefka.
I really needed this information.

I went in a technician here in my neighborhood and he told me that I can replace this fuse with a resistor of 1 ohm.
He told me that's safe, can I trust this information?

The electronic stores open only Monday, so if the substitution can be made for a 1 ohm resistor, I won't wait.

Thank you once again and I will wait for more this response to learn how should I proceed. \o/

 

No. YOU NEED TO USE A FUSE!!!! Use a resistor and you'll get quite a surprise... A smelly one...

 

Hm...
well, so one last question. What happens if I use a standard fuse 250v 2A? I think it's better than the direct link that I did.

Thanks again.

 

The fuse might burst or something else might blow.

Ok, Monday came, and I went in electronic stores venture in search of "lost fuse", but...
I not found the equivalent fuse (125V 2.5A) in electronic stores in my city.
But in all stores I was told that I can use an equivalent (a kludge) to make the circuit work without risk, or nearly so...
Despite this "help", unfortunately the information here were mis-matched and I will list the options they gave me:
(the interesting thing is that they all has many years in the field of electronics, but...)


Electronic Store 1 - Can I use a 250V 1.5A fuse instead of the original 125V 2.5A, because the difference should offset. The correct would be a 250V 1.25A fuse, but the store it had no. I bought some.


Electronic Store 2 - The same as the previous, but informed me that I need to use a fuse 250V 1A. I bought a unit for testing.


Electronic Store 3 - No matter the voltage, since the amperage is equal or slightly greater, so can I use a standard fuse 250V since the amperage is equal or greater. This is the only solution that I can't use because I don't have of this fuse value. (in amperage)


Electronic Store 4 - Can I make a direct bridge with a very thin wire that will working similar to a fuse, bringing some security to the circuit. I already have a suitable wire for it.

Well, of these 4 options I can perform 3 of them, so what's the best (or least bad)? Or if there is any other option to replace the original fuse 125V 2.5, that is best of which were described above.

I really very appreciate the help so far Sephirothkefka, I believe that these are the final questions and I will leave you in peace ... but if anyone else knows can answer too, please.

 

You could try the fuse and see what happens but I doubt it could work.

 

***SOLVED***

Sephirothkefka, I used a 250V 1.5A fuse and the CDX is working perfectly.

Until the service was well done.


I tested CDs and went well, and most of the time I tested cartridges and everything seems to be in order so far. I checked if it does not heat and the result is very good also. What is a surprise, because I'm in the middle of summer, I live in the northeast of Brazil, are now 01:00am and the temperature is 28ºC (82ºF)...





Thank you very much for your help Sephirothkefka, now I can finally close the CDX and have he back safely. \o/


LAST UPDATE

The CDX working very well with 32X, genesis games and tha Power Base Converter, but I am having a lot of work to calibrate the lens. At least, I had an evolution and not fail the musics as before. The problem is that the "Read Error!!" screen after some time pops up. (I'm leaving the game on screen, without playing, this error occurs in the presentation in CG of Silpheed).

After much search on adjustment of lens, I found information that documents the Mega CD model 2 could assist in the calibration of pots of the daughter board to adjust the reading, it really made a big difference and it seems that now while I did this update here, finally managed to get success and no more the screen of "Read Error!!".
I think I'm going to become a specialist in Sega systems, because I can work with the Dreamcast without the use of a multimeter and have raised many lenses.

Note: Impressive as the 32X leaves the image of CDX more pleasant and the strongest colours.
Unfortunately the Power Base Converter not working in the 32X.

 

where did you find that info on the pots?
i just did the ones on mine..without a reference...for a couple of hours...and some how got it from not reading to playing games. i could use a reference if i need to do another.

also you can get those fuses from http://console5.com/store/fuse-125v-2-5a-pico.html

 

I made a post over here you can reference:
http://www.sega-16.com/forum/showth...er-replacement&p=620535&viewfull=1#post620535

one of these days Ill make a proper schematic. also more info in the cdx thread floating around this forum

 

The voltage rating of the fuse doesn't matter, if you're using a "250volt" fuse, it should still be 2.5amps, the same as the original.

The 1.5amp fuse is probably boarder line, and may unexpectedly blow.
