Take out 5 HEX head screws and one black screw from jack pack cover. the pedestal will slide out from bottom. You do not need to remove jack pack cover as it is part of entire back panel.

troubleshooting PCB's of certain electronic units require advanced technical skills. no service manual of any source would provide specific solutions. the best you can get are schematic diagrams. if your field of expertise is not related to electronics, i suggest you let the technicians handle the problem for you. every shop have their repair cost qoutations. just be sure to ask for warranty of their repair. goodluck!

I'm not sure I completely understand your description of what you see. Do you have any audio and video of channels?
You could start by checking your different settings. Your inputs settings and display settings. You could be in a demo mode or in a calibration mode if you are seeing color bars colors (white, black, cyan, magenta, yellow).
