Help needed with monitor - pulling out my hair!

**kingvitamin** · 05-26-2005, 05:03 PM

To make a long story short - I am in the midst of my first full fledged carputer. I have the computer ready to go, and the Carnetix ready to be installed. I spent countless hours getting the touchscreen (Tview T-700TS) looking good in my dash. Well, now the monitor will not power on. I am pretty bummed to say the least. The monitor was working, but now after removing it from it's housing, and molding it into the dash, nothing. My question is: Does anyone know of any place I can send it to, and get it repaired? I'd be willing to pay to get it working, just so I can proceed. Summer is here, and I've already yanked my stereo which sucks. I've stared at the monitor a lot and realize that repairing it is way over my head. I resat ribbon cables a thousand times to no avail. I'm sad. Can anyone help?

Well that sucks. You are so close!

Have you checked to ensure that power is being fed to the monitor?

Check also to ensure it is the right polarity.

It is possible you have blown a fuse. Look CAREFULLY on the monitor board to see if one is blown.

Is this the first time you have used the screen with the carputer? If so, take the screen back to the last computer you used to test it. It might be that the car PC is not outputting the signal properly.

Give us more detail on what's up with the screen. Does it flicker/come on, LED glow, etc? Give us details on how you are powering the screen and what kind of car PC you are using.

yea...give us more detail on exactly what you did/didn't to it. These things arent horribly complicated and using a simple miltimeter you find a busted componant (if any)

sounds cable related to me

yeah we need input...give us input!

Well, I tested the monitor, before I took it out of the housing, on the same computer (carputer). It was working fine. As far as powering it, i am using a power inverter, so I can test it in my house. Absolutley nothing ishappening, when I try powering it on. No LED's, no flickering, no smoke, nothing. This is the first time I've attempted a carputer project, and first time I've ever had a dealing with a touchscreen monitor. I'm positve that the power is hook up correctly. You speak of multimeters and such, which I don't understand. I'm willing to try, but at this point I'm so discouraged, and anxious, I just want it working (hence the "will pay" part of my previous post). I gave the screen to a friend, who is having his professor look at it sometime, if he has the time. If not, I don't know what to do. I thought that it was simple too, until it didn't work, now I'm not so sure.

**** that didnt help! Did you check if it was working after taking it apart and BEFORE mlding it on the Dash?

**kingvitamin** · 05-26-2005, 08:06 PM

Yes. I'm almost to the point of buying another monitor, and tearing it apart, just to see if that will work.

Dont get excited now...

were you rough with it? did you drop it or bang it? did you wrench it in any way? was there ever power applied to it in an incorrect way? If not you havent much to worry about. Your screen is probably fine. If you did any of the above then there is somthing to worry about but still fixable.

It sounds to me like the button board cable is not properly in place. I know with the lilliput it has to be pushed up towards the left hand side

Argh...I almost don't want to hear this! I just got my T-view in today, and i'm most likely going to be molding it in the dash at some point.. This just makes me nervous!

If nothing is happening...uhh...are you using the fuse in the power line? Did you check that and make sure it's good? Check for any burnt spots on the board..disconnect and reconnect anything you had to disconnect while taking it apart...

**kingvitamin** · 05-26-2005, 09:11 PM

Yes, I double checked eveything. Everything seems to look OK, but I'm far from having a trained eye. The fuse is OK, that was the first thing I checked. As far as being rough with it, I made sure that when I wa working with the monitor/housing, that I removed the screen, and put it back in the box, and out of harms way. Like I said, I'm clueless. I must have done something stupid, because it won't fire. I tried reseating the ribbon cables with no luck. BTW, thanks for all the reply's and help, It really is appreciated. I hope the professor at my friends school might be able to figure out what's wrong and if it's fixable. If not, might one of the MP3Car.com gurus be willing to have it shipped and have a looksy? This stuff is way above my head.
