Title: Turbo Express Video Issue - Replaced the Cap - Wont Read Games
Post by: christoph on March 09, 2010, 10:01:09 AM: http://www.pcenginefx.com/forums/index.php?topic=5015.0

I just found another Turbo Express. It had the "black lit screen" issue. I followed that thread and replaced the cap. Now the screen lights up white like its suppose to - but when I put in any games, it doesn't read them. It just stays white?

UPDATE: So I plugged a Turbo Vision into it and the video shows up just fine.. hmmm
- sound doesnt work at all, but i know how to fix that..

Any ideas?

Has worked great for me in the past. Prolly don't want to turn it on tho until you've given it time to work it's magic and dry a little.

Title: Re: Turbo Express Sound Issue - No Sound to Low Sound..
Post by: christoph on March 09, 2010, 12:34:44 PM: I got the video to work! Thanks mates. Still cant get the sound right. The sound didnt work AT ALL in either the headphones or speakers. I did the mod from the sticky above and now they both work but the sound is low on each. Any recommendations?

Thanks!

Post by: unclebugspayton on March 10, 2010, 01:43:47 AM: by replacing the video cap will it clear up the image?

Post by: christoph on March 10, 2010, 03:51:19 AM: Yeah I figured I might have to get those caps. 100uf 35v caps will work for those right?

and I replace which ones, green or blue? (I already removed one cap in the green and replaced another with the guide)

Post by: kattare on March 10, 2010, 05:27:11 AM: you're probably going to want to replace -all- of the caps. even the ones that haven't already failed are going to fail sooner or later.
Title: Re: Turbo Express Video Issue - Replaced the Cap - Wont Read Games
Post by: MotherGunner on March 10, 2010, 05:35:31 AM: Agreed. I may need to get mine all eventually replaced. So far it works fine.
Title: Re: Turbo Express Video Issue - Replaced the Cap - Wont Read Games
Post by: christoph on March 10, 2010, 07:17:37 AM: Yeah probably a good idea. Replace all the circled ones, right? I can just use the aforementioned 100uf 35v caps?

Thanks for the tips!

Post by: nat on March 10, 2010, 12:15:59 PM: The ones circled in green are all the ones related to audio. The blue ones, I'm not totally sure what they do, but it doesn't hurt to replace them as well.
