now, sometimes when i start my truck, my screen will only open horizontally, not vertically..i have to close it, then re-open it..what do you think is going on? is it fixable?

its the flex ribbon. eventually your monitor wont come out at all. its a very common problem for the monitors. it can be fixed tho where i had mine done thru a guy on ebay with the user id rch72. i recommend him to everybody, they play no games a work out of a store front and not a house. quick turnaround time too!

Very easy fix.....Clean the ribbon cable contacts!
