Audio noise, only with Lilli LCD on.

muldrick · 08-08-2004, 05:13 PM

OK, donnt yell at me. but I didnt find any threads on this: I have all my audio noises gone except I have a buzzing noise with the Lilli on only.
The screen is installed into my cluster, in front of my speedometer (I use the GPS for a speedo).
My PSU and inverter are grounded. I am running power for the Lilli LCD to my fuse box. (12 V with the egg) I have tried different fuses and ran it straight from the battery. Still have the buzzing noise through my stereo. I am running wires from the PC sound card to my head unit "audio in". Regardless, the buzz is only with the LCD on.
I do plan to get an Opus sometime and run the Lilli power from that, but for now I'd like to get rid of the noise.
Any help????

One of my noise problems I have is that, the same for me. When I switch on the Lilliput and engine is running, noise, but when I switch off or stop the engine, no noise. ????????????????

The noise you are hearing I BET comes from the lilliput power egg. Its a piece of **** and needs throwing. I thought i had suddenly developed alternator nise until i realised it the stupid little egg. lol

Since I use an inverter, I decided to use the Lilli AC adapter. Now the noise is gone AND the LCD is much clearer

i have that sound too...i might try switching to a different way of powering it...

do you think it could be the screen emitting emi? cuz i get sound from speakers too

I don't know. I was gonna switch to the Opus PSU, but now I'm worried I'll get the noise back

Hmm.. i Wondered about that aswell.. I sometimes have really poor quality on my Lilli.. What is the egg for anyway ? can't I just cut it out between ? Or does it server an important purpose ? Can I replace it with something else ?

Thanks

The egg (I believe) is a (cheap) regulator to keep volts around 12+. Since a car's volts can be anywhere between 8 to 15+ volts, I wouldn't remove the egg. I have read threads about people doing that without problems, but it seems a little "chancy" to me. Search other threads about it. If you're using a dc-ac converter, I would just use the ac adapter and plug the Lilli straight into the inverter (using the ac adapter). Mine works great now. no noise, no screen flickering.

If you have a dc-dc converter, you can power the Lilli without the egg from the PSU. But you better check other threads on that also...
