fuzzy lines on EPIA C3 800 mhz

samc · 04-01-2003, 09:47 PM

Hi, I'm using the rca video out on my EPIA C3 processor 800 mhz board. Lately I've noticed that the video out has blurry lines. Not static persay but like fuzzy lines. I just started getting this recently. Anyone else get something like this?

Up till now, the video out was just fine.

nobody gets fuzzy lines with their screens? I'm almost toying with the idea of a 7" xenarc.

No Sam! It's only you

Have you changed anything or added anything to your system that could've caused interference? Have you jostled anything or knocked anything loose? When did it start to happen? Check your grounds and connections to be sure that nothing has come loose.

hi,

I still don't see whats wrong. I haven't touched a thing. But I'm certain its the motherboard. Vga still works fine, but rca has fuzzy lines. Damm too bad xenarcs cost so much

You have to give some pictures of it and more info.
Didi the lines come when the engine is on and stuff like that....

I had a fuzzy screen and thought I needed glasses but it was just the RCA input, I then opted for the Xenarc 7.2" VGA screen and everything has worked fine from then to now!

Take my advice, don't use composite input in the car, it's just not worth it in the long run.

Here is a pic of my rca video out on my tv. i get the same fuzzy lines on 2 tvs, and 3 separate lcd screens that I tried.

Here is my stuff:
EPIA 800 C3
Crucial 256 Pc133
40 gig Hitachi 2.5"
4x Toshiba dvd-rom 2.5"

I've tried almost everything and I always get hte fuzzy lines. I've narrowed it to the motherboard
I've replaced HDS, rca wires, no dvd, memory and still Fuzzy Lines.

I hope someone can help with this fix.

It looks like interference - is there anything around it that could be causing that? Is this setup installed in your car or is it still a desktop carputer? If it is a desktop - try moving it to another room or something to be sure that it's the board.

yeah its on the desktop right now, because im wiating for an opus.

But yeah I'll try in another room again. I must nope that when the dvd-rom is spinning, the fuzyz lines do get worse, then stop when the dvd is done. but I cant recall putting any magnets near the comp.

try to use +12V amp filter.
I got one og them and it works fine.

hi what is a amp filter?

NJay · 04-07-2003, 11:14 AM

I get a similar effect with my Eden 800 as well but under slightly different circumstances.

If I power the system using UK mains then I have no problem with the TV-OUT. However if its powered though the 12VDC - 240V AC 300w invertor in the car then the interference appears on the screen when the HDD is being accessed. Even though the HDD is still spinning it stops when the drive is not being accessed.

The USB2 DVD drive does not cause any interference at all which is suprising since the LCD Screen and the USB2 DVD drive are both powered from the same source and are independant of the invertor

And I had the same problem with the audio, I get a 50hz crackle through the RF modulator using the invertor, I got round it by using a DC-DC PSU and ran the screen direct from the battery.

Ow. Sorry for mmy english.
What I mean is:

Witgh +12V Amp Filer I meant current filter.
It is a filter that you connect between +12V (example battery) and 12V whire on you screen. The curren filter is also connected to the car chassis.

The funstion is:
The current filter is sabilizing a curret that goes to the LCD.
If you got a Alternator whitch is making a noice on you power the current filter will sabilize a current. (you will get a "clean" current to you car) the same as you connect a LCD to external battery...

I hope you understand what I mean..?

Sorry for my english. I am not so good in technical english..
