Hi and welcome to JustAnswer, Thank you for the question and your patience. Should you still need assistance for information purposes only... Initially, if the yellow wire shows an always available +12 while the red receives a switched +12 and the black wire grounded properly to a metal frame/chassis (not only to the harness), then it would not be a wiring/connection concern. The described symptom would almost always point to an internal hardware issue or more particularly, primary checks on likely suspects would be on:• LCD screen (least likely);• DC-to-DC converter/backlighting supply (likely);• flex cable/connector (most likely).All of the above would require that the unit be opened up for visual inspection, voltage/continuity/resistance checks, confirm faults and effect repairs. I realize that the above information may perhaps be not what was expected.Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multimeter and even a soldering iron?Please post back how you would want to approach this and/or should additional information be needed.
