Overhead and MCP Panel Blank

[Guest pademo]

Hello everyone, Yes, this is my first time and I wanted to know if anyone else has had this problem (B737-600 or 700 2D view):On startup during a night-time flight when the main panel shows up, the MCP panel blinks once and almost everything in it disappears. Then when I check the overhead all of the buttons and switches have disappeared. Some of the digital displays remain.Here is the interesting part, if I click where the panel lights are on the overhead and click on the lights to turn on and off everything returns, all the switches, knobs, etc. The MCP panel then lights up again with all the displays working properly.Anyone else seen this problem?

Once when I was going from pre-dawn to daylight, my MCP panel was covered with a grey rectangle. This remained only for a short time and I think when I cycled views it fixed itself ... never seen it again.- Neeraj.
