  • Page 3: Safety Warning

    Safety Warning Dangerously high voltages exist on the Power Supply Unit (PSU) PWB (See Fig 1). FOR THIS REASON, THE RECEIVER MUST ALWAYS BE DISCONNECTED FROM THE MAINS SUPPLY BEFORE ANY WORK DETAILED IN THIS MANUAL IS CARRIED OUT. Caution High Voltage Fig.

  • Page 4: Dissassembly

    1 Dissassembly 1.1 Cover Removal Remove the foot by releasing the clips circled and easing the foot carefully away from the unit. Remove the 2 screws located at the rear of the unit (shown arrowed). Lift the front of the cover slightly and slide towards the rear of the unit until it is clear.

  • Page 5: B Board Removal

    [ 1.3 ] B Board Removal Remove the cover and front panel as indicated in [1-1] and [1-2]. Disconnect CN600 power cord and remove from unit. Remove the 1 Philips screw from the rear panel. Remove the 3 Philips screws from the circuit booard. The B board can then be lifted clear of the chassis.

  • Page 7: Entering The Tt Command Number

    Entering a ‘0’ digit after any other digit entry (thus making the command a multiple of 10) will immediately reset the display and perform no action. 3.2 Example VTX-D800U requires 3 digits. Therefore the following sequences would be valid to issue a test command… Sequence Result 0 ⇒...

  • Page 8: List Of Tt Commands

    4 List of TT commands Depending on the STB model the number of digits which are capable of being entered will vary, therefore any leading zero have been omitted from the TT number defined in the list. Entries should be made according to the description in section 3.

    5.0: Power supply The power supply in an integrated part of the Main PWB, and contains the following functional blocks: - The main components are:- Mains Plug, Lead and input filter Primary and PWM Controller Transformer and outputs Feedback Circuit Post Regulation Circuits.

  • Page 12: Power Supply Detailed Description

    5.1: Power Supply Detailed Description The most common failures will be fixed by replacing the following components. PRIMARY BLAST KIT:- F600, D600, D602 D601, IC600, PH600, IC602, D604. The components detailed below have the following functions: Fuse, F600. T1.25A 250V Always replace the fuse, with the same type and ratings as the one removed.
  • Page 13 D602 Catch Diode The catch diode is in place to help limit the excess voltage to the MOSFET to guarantee the parts ratings. If the STB is victim to high mains this part is the first to fail trying to protect IC600. If damaged primary replace the blast kit.
  • Page 14 Secondary Operation The secondary outputs from the transformer will all rise at the same time, 3.3V reach its regulation point first followed by 5.0V, +21V and 32V. If the LED is flashing about once every second then a transformer output is shorted to GND or overloaded. Remove FB610 (33V) Remove FB607 (+5V) Remove FB605 (+3V3)
