I put it in circuit and it seams to work. I have yet to test for a long period of time but as or right now it seams to work fine ?

Dose anyone know if the L7812 voltage regulators the same a UA7812

Well I'm just an amature trying to get my intv working. But if you want I can show you what I did. Idk what parts I even used lol I just found a old cable I cold rig something up to

Yah it works that's what I used. Like a socketed ic connecter. I soldered it on the cable and it fits in the holes perfect ?

Ok. And I got it from an old PC

Now did you know if the pb was good ? And

Yah I've already got it planned out but thanks ?

Oo wait nevermind ? I just read that wrong. Yah I already got a cable lined up

Like what do you mean? Like my meater?

I have been checking anything else I could find that could go wrong and I found that my ribbon cable was no longer making continuity. So I am also going to have to replace that.

That's what I suspected. I had one that works from the other PCB and I swapped it in there and when I did so it wasn't working and I know it was before. Maybe I heated it up to much and damaged it? But I also know that that 23v goes to the one leg of that regulator, you think that can caz it to go bad if there rated for a lower voltage or something? I believe that is why I'm not getting any picture, but why on both pcbs one that should be good I get the same 20v on the cap to ground? Surely there both not bad, heck the one I just about replaced everything on it. There's no way that I can be still a bad caponit on there. I have yet to change the diods and main caps but I am planning on doing so. Also I looked at this video showing how to test a good transformer and all my readings came out ok so I'm really stumped unless it gets hot,witch it dose and makes the voltage differ. Even when the consoles shut off it gets a little warm if it's been plugged in for a bit.

I've watched this video and checked the voltage. All then we're the same exact the second prong that's 12.v and that goes right to the one prong on the voltage regulator.

Just for reference how do you test one of those voltage regulators? Is it ///////////////// / 7812 / /. / ///////////////// L. L. L. In. Grd out 5.v 12.v So wold you just test the out to ground ?

I just checked the ribbon cable with the power on I'm only getting 2. Something on the second prong

Yah that's my thought I know on my old pcb that the 12.v regulator was bad but with the new one everything is good the odd thing I saw was when it was powered on the 12 was at the 2 prongs by the 10000 if cap but on the other side of the blue wire it was only 5.somthing

I think I might have blown something on the logic board. I have accidently shorted the 12v regular to ground with the logic board plugged in. So if you have any ideas give me a shoutout. Or if you think it's just best to get a new logic board you'd probably know where to get one

Also when I try it on the TV nothings coming up it's just all like static no black screen

Ok so I got another power supply thanks to IMBerzerk and I'm getting about the same result. 22.1 on just that capacitor and about 20.2 when it's all plugged in the logic boards plugged in ... So I'm feeling its the transformer

Ah I see

Do you know what the k means on the diodes

Ok thanks ?

I got 10.6 on both

I'll test it tomorrow i don't have time now

I mean it did seam to help alittl you think if I were to add more resistors it could get back down to were it needs ?

Yah those resistors were real hot that on there to I didn't know if that was normal or not.
