Introduction This Service Guide is for reference for qualified persons and technicians, as a fault finding and rectification guide only. All safety and electrical precautions must be strictly adhered to. While Torch Computers Ltd gives permission for repairs to be carried out, the Company accepts no responsibility for any losses resulting from such work, and any damage caused will invalidate our warranty.
Voltage Selection Torch Computers 46” and 52” LCD screens, model Series EN063/69K, are designed to work on both 110-120 VAC (60Hz) and 220-240 VAC (50Hz) 435 watts mains electricity supplies. Normally, the screen will be delivered to the end user with the correct voltage for the local supply already set. Type UK – (5amp fuse fitted) used in United Kingdom, Singapore, Hong Kong, and some other countries. The other end of the cable is an IEC socket, type C13.
However, if the local plug is not the USA type, then a cable must be made with the local plug at one end and an IEC type C19 socket at the other end.

To fit the cable, undo the knurled silver thumbscrew and remove the side access hatch. It is not really necessary to remove the rear access hatch, but you may if you wish. The cable can be led out from the screen in a number of different ways according the needs of the installation.

Powering on the screen When mains power is applied to the Torch Computers 46” and 52” LCD screens, a bleep or a series of bleeps will be heard. This is the UPS (uninterruptible power supply) initialising. As delivered, the computer will not power up when the mains power is applied; the screen is set up so that the LCD panel turns on as soon as power is applied, but will shortly go into stand-by mode. The red light will come on and after a short pause it flashes.
Computer Interfaces The computer interfaces are not intended for the use of the end-user, and any problems caused by so doing will be outside the warranty.
Uninterruptible Power Supply (UPS 300K/500K - 110 or 220vac 60/50Hz) The Torch Computers 46” and 52” screen are fitted with a UPS whose purpose is to protect the unit against mains fluctuations. If the power is lost, the LCD panel will go off immediately, but the UPS will keep the computer running. During this time, the UPS bleeps continually. If the power is restored within one minute, the LCD panel will come back on and normal operation will resume.
Troubleshooting the UPS Problem When switched on LED’s do not light up and there are no bleeps (the green LED, marked 4 in the diagram on the previous page should always be on when mains power is connected) No Green power LED Red and Amber LED’s are both on Green and Red LED’s are both on Possible cause UPS may be disconnected from the AC mains input Actions Remove the AC power input.
Disconnect the red and black cables from the UPS by releasing the thumb screws, and unplug the white connector and remove tray from screen. Fuse and Battery Replacement 1. 2. 3. 4.

Speaker Orientation Option This feature enables the sound to be switched between the portrait & landscape orientation before the mounting of the monitor. If the screen is mounted in portrait orientation but with the speaker switch set to “landscape” the speakers will appear to be top and bottom instead of left and right. For correct stereo audio operation, the speaker switch should be set to match the orientation of the screen.
Wall Mounting Two wall mounting brackets are provided, one each for portrait (“vertical”) and for landscape (“horizontal”) mounting. In the rear of the screen are three holes, each 30 mm (13/16th inch) square, of which two are used for each of the two orientations.
When the bracket is securely fixed to the wall, the screen can be hung upon it, using at least two people to lift it. Locate the guide fins into the guide slots and slide the screen upwards until the screws drop into the square holes. Lower the screen slightly and ensure that the screws have located correctly in the holes within the screen. Guide fins Adjustment nuts If the screen is not exactly level, the adjustment nuts can be used for fine adjustment.
