    Default Turbo Express not working. No power. please help!

    Hi guys! New to the forum. Glad to be here!

    I been trying to fix my Turbo Express and joined this forum so I can get some professional advice from you guys. Ok, my TE gets no power at all with new batteries or with AC adapter. I did a ton of research so I went ahead and did a few things.

    ...replaced the 1 AMP fuse and the continuity checks out ok

    ...replaced the only leaking capacitor I was able to find (the large sound capacitor)

    ...cleaned all the solder joints with 99% isopropryl alcohol and cleaned all the soldering pads

    ...cleaned the switch terminals

    I watched countless videos on youtube and read many articles on how to repair these things. Many of these places lead me to the 1A fuse which I already replaced. I have prior soldering experience and a minor knowledge in electronics.

    Can anyone tell me what did I miss? The system doesn't power on at all. Screen is black as if there are no batteries in it. Please any help would be appreciated.

    I would replace all the caps, not just the one. Even if they haven't leaked, assume they've gone bad.

    Thanks! I was thinking of doing that, but why would some other bad cap cause no power and no backlight?

    Some people have leaked video and audio capacitors and their TE still powers on, and they get backlight. Makes no sense.

    Anyways I guess this is my only option, I will go ahead and replace all the caps and see what happens.

    btw what is 7508 reg? where is it? I can't find it

    Start with replacing all the capacitors, it needs to be done anyways (you'll probably be surprised by how much leakage there is underneath the caps that you cant see until you pull them off) If it still doesnt work after all that, let me know and I'll direct you to someone who knows a ton about these things.

    thank you sir. will try that definitely.

    How do I get to the capacitors that are under the metal plate in the center? I can't see how to remove the shield.

    It's soldered in place. Examine the edge of the shield and you'll see where the tabs stick through.
