Casio TV gets too much static - HELP!

[zzaz3]

I just spent the last 2 days working on my 1st portable. I got every put together and it works great! The only problem is that if I leave it on for more than 2 minutes the screen gets REALLY fuzzy and there's static everywhere.

I have no idea what to do or what to look for. I checked all my solder points and everything seems fine. Any ideas?

Ok, now the screen is messed up all the time.

Low batteries?
Shield wire?
Chek that

are you using rf or composite?

I have a little experience with a casio screen, and the picture has always fuzzy. Somebody told me to put resistors on the video line, but I didn't get to because the screen died.

I'm using composite. I bought some brand new batteries and put them in and that helped reduce the static a lot! Thanks so much!

But now the colors are kinda over saturated and depending on what channel I put it on, the colors will be completely off. It's usually allways blue. I have a 10 Ohm resistor that I'm going to try installed and see if that fixes it.

Alright, I added a resistor and everything on the screen seemed really faded, So I added another and it seemed exactly the same. I decided to take the resistors off because I'd rather have it over saturated than under saturated, but now it still looks faded. Even without the resistors attached.

The only thing I did was make the wire sending the video about an inch longer so I could solder the resistor to it. You think that would of effected it?

[zzaz3]

Nevermind. I ripped the ribbon cable connecting the screen to the main board. The whole thing's ruined

Don't say that, you can connect it with wires by yourself.

[themadhacker]

what type of casio was it?

[zzaz3]

It's to thin. There's no way I could fix it. I'll probably just move on to another project and try and do better this time. All I need is a new screen to use. Any recommendations?

It was a Casio TV-970b.

3,5"? Check the review in this forums.

[zzaz3]

Yeah, I found that thread shortly after I made that post. Those screens look a lot nicer than a pocket tv. As soon as I get money in my paypal, I'm going to order one.

So, what do you guys think I should do with the screen? Should I make a dreamcast portable or a PS1 portable?

[JariV]

Dreamcast, I haven't seen much of them. But you should make another topic / rename it xD

[themadhacker]

It depends on howmuch of a challenge you want. The psone is an easier portable to make, and requires (in my opinion at least) less skill then a dreamcastp.

[zzaz3]

I dont really care much about my dreamcast and I like a challenge. So why not make a DC portable?
