New batteries and I get nothing. Any ideas? This would be a great loss if I cant get it to work. But i did pay 25 cent for it lol
TurboGrafx Turbo Express gets no power

7508 reg gone.
Fixable?
Check da fuse

The 7508 is very replaceable. Just don't attempt it without prior soldering experience.
Very easy to replace but very easy to screw up.
I have some experience and I'm willing to give it a try. Know of any walk throughs?
As bust3d said, check the fuse. The express is pretty easy to take apart, just be careful of the ribbon cable connections as they're a little bit fragile. If you look on this board picture below, you'll see the fuse right below the power switch. Its a small black rectangular box that says "50C 1A". Check it for continuity. If its blown, you may have to get a fuse holder and wire in a different style 1A fuse, as that original style is not easy to find. Sometimes you have to run it remotely with wires since there's not a lot of room there to fit a fuse. If you replace it and it blows again, then you've probably got a short somewhere, possibly caused by leaked capacitor electrolytic (these caps are notorious for leaking) In fact, you should probably have all the capacitors replaced if they havent been done already.

Thank you do much. I'll try it this weekend and post a video to help others
No offense but if you need a walk through it is too advanced for you. Removing the part, placing the new one and soldering it in is as basic it gets in the world of repairing electronics. Through hole is a walk in the park compared to some of the SMD work I do by hand, the hardest part (orienting the replacement part) is already done for you by virtue of the old one still being in the board.
I fix things. You name it, I'll work on it. Want something modded? Recapped?
I thought the point of this board was to help less "advanced" people, and not snark at them?Originally Posted by APE992

I learned to work on stuff by asking lots and lots and lots of questions and then making lots and lots of mistakesI'm still not that good at any of this stuff, but over time I keep getting better and better. Being willing to try is admirable in and of itself. Some people are too afraid to even attempt to repair their stuff.
ha true but maybe start with something less valuable than a turboexpress
That was not snark. This is EXTREMELY basic soldering: apply desoldering braid, remove solder, remove part, place in new part, solder, done.
The truth isn't always candy coated with a shiny, pretty bow on it. Not everyone should attempt something just because it is possible: reality hurts.

...And who, exactly, are you to determine whether someone should attempt something like soldering or not? So in your world, somebody who doesn't know how to do something shouldn't attempt to do so, even after asking to be shown how? Again, this is a board to help people do so, and your little comment did nothing to contribute, aside from being a negative asshole about it. If you're not going to contribute something educational, then by all means, STFU.

I offer advice, not judgements but it sure sounds like you're offering judgements. My advice does not have to be taken as gospel and can be disregarded though that can be a bad idea at times. How about contributing a useful guide yourself or are you just going to offer negativity? I can see I sure hit a soft spot in someone's ego though.
As I already stated, you desolder the old part, insert the new part and solder it in. Simple and easy but easy and simple to screw up as I have done so in the past. I have also cleaned up the mistakes of others who have attempted mods they were not yet prepared for. Though in this case I don't see why OP couldn't handle it himself I just wanted to be sure that he had any doubts he would listen to them. I've got the scars to prove that doing that might save you a 2nd degree burn from a heatgun.
PS: I'm working on a BS in Electrical Engineering and have over a decade of experience with soldering and electronics repair. I didn't realize I should have my resume pinned to my lapel.

You need to start small. There's a gray area beyond which jobs are no longer reasonable. We're talking soldering not the infinite monkey theory. Dumb luck only goes so far. Past that difficulty level one isn't ready to handle, probability is greater you'll irreversibly hurt yourself and/or the object in question, over achieving results positive enough to justify said risk.
Lum fan.
So how's the weather up there from your high horse? You offered only one sentence of advice, then tore into the OP fourposts later.....and I hit somebody's sore spot? Pot meet kettle.

As far as the rest of your post goes, bravo, you're going for a degree. Too bad you're taking the Dr. House route in "bedside manner," so to speak, instead of that of say, Einstein.
I'm done derailing this thread and will offer no more public replies.

Which is all you've done thus far.
To OP: if you'd like help figuring out where the regulator is I can help but I don't have any images on hand of the Turbo Express PCB.

I'm having the same problem with my TE. Any updates on this?
