MQ100 Screen replacement
Removing the Front Panel
To remove the upper front panel metalwork, removed the eight M4 Butthead fixings using a 2.5 mm Hex key.
Once the eight fixings have been removed, the metalwork can be lifted off. The top metalwork is into parts the blue overlay and the black lower metalwork.
Care should be taken to avoid the screwdriver or Allen key slipping, as this can cause significant damage.
The screen is attached by four screws, one at each corner. The screen is spaced off of the main PCB with hex nuts on these screws which should be retained for later use.
The screen is connected at the rear of the screen which is accessed by removing the back panel and the touchscreen is connected by a green and white ribbon cable to the left hand side on the top of the Main PCB. It is often easier to disconnect at these locations prior to physically removing the screen bolts.
To remove the rear panel remove the nine screws around the three edges.
Moved the panel forward away from the console and it should be possible to cut the zip tie and remove the connector by sliding it away from the rear of the screen. If you decide that this is not possible then an alternate method is to remove the lower front metalwork and completely remove the front PCB. Instructions for this appeal further down this article.
Once the two connection locations have been disconnected and screw the four retaining bolts at the corners of the screen and remove and replace with a new screen. Reattach electronic connections at the front and rear adding the new zip tie to stabilise the cable underneath the PCB. Reassemble in reverse order ensuring that no buttons or keys catch the front metalwork.
Prior to full assembly it is worth testing by connecting power and calibrating the touchscreen. Care should be taken to ensure you do not come into contact with any live components.
Full Instructions for removing the main PCB
The first step in removing the lower front panel metalwork is to remove the favour knobs. The armrest should also be removed.
Once these have been removed, before securing screws in the lower front panel can be removed using a 2.5 mm hex key. There is also a securing screw between fader number 10 and the cross fade fader. This should be removed with a 1 mm tip PosiDrive screwdriver.
It is possible to remove the metal panel without causing damage to the end cheeks. To do this, push the right end cheek out as far as possible with one hand, while lifting up the panel on the right-hand side with the other. The front panel metalwork should simply lift out of the right-hand side.
The front panel should be stored safely to prevent damage to it.
When replacing the panel, ensure it is pushed as far to be right as possible to allow the free movement of every bottom. It may take several attempts to position it so that all the buttons have free movement.
The PCB is attached to the chassis by eight M4 spaces. These should be removed using a 7 mm nut driver tool. There are also three screws with a shake proof washer at the bottom of the PCB. These should be removed using a 2 mm PoziDrive screwdriver. Underneath these screws should be a nylon washer. Store these safely as they are required when reassembling.
The spaces that hold the PCB to the chassis are made of brass, and are therefore easier to share off. Do not use large amounts of force when removing or replacing.
Once these have been removed, the PCB should be lifted out from the right-hand side. After lifting approximately 4 inches, you'll be able to remove the right-hand working light connector; This can simply be pulled away from the board. The connection cable to the front panel will next do to be removed. This can be achieved by pressing on the tab, and pulling the connector away from the socket.
On newer 2014 models the lamp connectors may be attached to the main back panel and do not need to be removed.
