Thread: 05 corolla, Lilliput touchscreen & JVC headunit - lost power

I recently modded my 05 corolla and installed a screen and a new head unit, The screen is tapped into the ground for the head unit and the power for the head unit, the screen is a Lilliput 7 Touch Screen Touchscreen my head unit is a JVC KD-ADV6270
The ground is on the metal tube in the dash and the hotwire is off the ignition switch.

The head unit is connected with a aftermarket wire connector that plugs right into the factory plug.

Everything was working great! today I got in my car and I had no power to the screen, head unit, clock on the dash panel or 12v outlets.

I checked all the fuses under the hood all of them checked out fine except two of them, I belive they were 10's, I dont recall the posistion of them right now.

The fuse on the head unit was fine, the fuse going to the screen was blown, and I also noticed that the wire for the screen had gotten a little hot and melted. I fixed that, replaced the fuse... and still nothing.. no screen, dashpanel clock, head unit or 12v outlets.

If I check the aftermarket plug going to the factory plug, there's no power with the key on.

The constant is fine and lights up bright!

I didnt check the plug directly at the factory connector, But I'm sure that's dead as well.

Could it be possible I fried the relay? I would appreciate it if anyone could point me in the right direction or if someone had any further things for me to check.

I have a Chilton's Manual but it's not very detailed, I'm stuck,, bummed out and praying I didnt fry anything really bad... I do have all the lights on the dash panel still, the only thing that doesnt light up is the clock.



Thanks for any assistance!!!

Dopey me, I didnt realize there was another fuse block crammed way up under the dash... It turned out to be the 15 amp fuse for the cig lighter...
DOH!!!

Hi, I have a 2003 corolla too. I am putting in a mac mini computer and 7" lilliput monitor too. I am getting the monitor that does NOT flip out. It is just flat and touchscreen. Can you tell me... Does the screen fit in the factory stereos place? I am trying to figure out if it will fit good without a bunch of headaches. Do you have pictures of your setup? Please send them if you do! Also, what did you do with yours? A computer?

Thanks, Colton
