I keep blowing LCD Controllers
Alrighty guys here whats up:
I bought a new screen from motor city tech (duayn) for $200 w/ hdmi and touch. I keep blowing up the LCD controller and at $56 a pop, its expensive..
My car is a 05 Crown Victoria.
Initially, I wired the screen directly to the radio harness +12v and Ground. (I even tried using an "egg" from a Lilliput power adapter to fix it. still blew it out the water.
Then I tried hooking it to the psu floppy cable. (using one of those barrel connector setups)
So, Today, after spending some time running new wire threw the car, I blew my 4th (or 5th) board.
So I had my mechanic friend bring by his voltage checker. At the radio im at 12v constant (we sat with it hooked up for 5 min and watched it) And the ground registered 0.0
So then I tested the barrel connector, the inside pin showed between 11.8 and 12v. and the outside (ground) showed .01 I checked the silver plate and it was also .01 So.... is that a problem as I think it is?
And.... whats causing my screen to blow.
As of 1/17/12 I am throwing in the towel on this project. I have invested way to much for this screen, and have not gotten good results. I am now working with the seller to create me a better solution. I would recommend anyone needing a custom screen go to duayn. How ever, I would not recommend going with no-name parts. Spend the extra and go genuine.
