So noone has any other idea of what I could try to fix this?!?

Sorry for my late response. I have been out of the country and so unable to work on my problem!
I tried to upload the USB serial firmware but no luck.
- I connected my broken arduino via another (working) arduino,
- I downloaded and instaled the Atmel Flip program,
- I can't reset 16u2. I follow the instructions on the site you suggested, but nothing happens.
- I am also unable to establish the connection. The error reads: "AtLibUsbDfu.dll not found". And then "Could not load dynamic library".
- and also, how do I download the firmware?!?

Yea, both main chips work on one board, so the chips are ok.
I can't try this loop back test, because the computer does not see a device. And if it can't see it, I can't do the test...

I'm using the yarvik xenta 10" tablet - works great with the arduino. Why?

I'we done exactly as you told me, but it stil doesn't work.
I'we removed the atmega chip from my spare arduino (the working one), connected the pins as you described and connected my spare arduino via USB to my computer. This way I got power to both my arduinos and the "broken" arduino is normaly running the previous program (I recently uploaded the "blink" program, just to know if it is working). But when I want to uplod a new program to the "broken" arduino (now via spare arduino) this happends:
- the spare arduino is reciving the program (RX light blinks)
- the "broken" arduino does not recive the program
- arduino program on my computer gives out the "not in sync" error.
I than also tried switching the atmega chips and they both seem to be working fine.

Any other ideas what it could be?

About the "tablet". I was referring to a tablet PC, like an iPad. And as I said via my tablet I can upload a program even to my "broken" arduino, although the tablet indicates it hasn't finished uploading. But the new program runs fine...

Tried this, but stil nothing!
The strange thing is, that it was working fine before, but now its like the computer doesn't see the arduino, although it recives power and the program on the arduino seems to bo working. But as I said, I don't like the beeping when I plug it in...
I also tried connecting it to my tablet and it actualy works. It sees the arduino it comunicates with it, I can download data to it... The only strange thing is, that even when the data it downloaded the tablet stil "downloads" to it and I have to stop it manualy. But the new program runs normaly...
Any idea what it could be? Could I have damadged the board somehow?

Same thing happened to me today. I just pluged in my arduino UNO (like a couple of time before) and the computer beeped 3 times indicating that something is wrong. And now the port (COM4) does not show up!
Any ideas what could be wrong?!? BTW, my other arduino UNO works fine...

Tnx for the answers so far, but I'm stil where I started from. Any ideas what kind of a monitor I should use?

Could I connect this to my Arduino? What would I need?

Hi guys!

I'm new to this forum and quite new to Arduino in general! smiley-roll-blue
I would like to graphically display the operation of a system I have been working on. Basically I would like to see on display what I see on LABView - different elements, connections, gauges... Is that possible, and if it is, what to I need to make if work? So far I have a Arduino UNO and a Sensor Shield (which I probably need to connect the LCD). For the LCD I was thinking of using a 5" TFT LCD (if that is ok?).

Thank you for all replies,
Matevz
