EN 4 2. A02U AA Safety Instructions, Warnings, and Notes 2. Safety Instructions, Warnings, and Notes 2.1 Safety Instructions 2.3 Warnings • Safety regulations require that during a repair: • Due to the chassis concept, a very large part of the circuitry (incl. deflection) is 'hot'. Therefore, connect the set to the mains via an isolation transformer. • Replace safety components, indicated by the symbol h, only by components identical to the original ones.
PAGE 5
Safety Instructions, Warnings, and Notes • • The semiconductors indicated in the circuit diagram and in the parts lists, are interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors. Manufactured under license from Dolby Laboratories. ‘Dolby’, ‘Pro Logic’ and the ‘double-D symbol’, are trademarks of Dolby Laboratories. 2.4.4 • Schematic Notes • • • • • 2.4.

S-VIDEO INPUTS With either of the VCRs (or accessory devices) ON and a prerecorded tape (CD, DVD, etc.) inserted, press the PLAY button to view the tape on the television. Press the AV button on the remote control to select the AV1 channel for accessory device number one, or the AV2 channel for accessory device number two. AV1 or AV2 will appear in the upper left corner on the TV screen depending on the channel chosen. Turn the VCR (either one or two) or accessory device and the TV ON.

Mechanical Instructions 4.3 4.4 Service Positions This chassis has several predefined service positions, for better accessibility. They are explained below in more detail. 4.3.1 A02U AA 4. EN 9 Assies/Panels Removal Sometimes, it can be necessary to swap a complete assy or Printed Wiring Board (PWB). How that can be done is explained below. Large Signal Panel (LSP) 4.4.
PAGE 10
EN 10 4. Mechanical Instructions A02U AA 1. Remove the fixation screw (1) (if present). 2. Release the two pegs (2), by pushing them towards CRT. 3. At the same time, pull the complete module away from the LSP bracket (3). It hinges in the LSP bracket. 4. Remove the four fixing screws (4), and remove the panel. 4.4.4 To get access to the SSB test points, do the following: 1. Put the LSP in service position 1 (as described above). 2. Remove the fixation screws, which hold the SSB-bracket (1). 3.

PAGE 16
EN 16 5.6.2 5. A02U AA Service Modes, Error Codes, and Fault Finding fault detection/protection must be enabled only after the chassis power supply has been established. Likewise, after the line drive starts, the deflection detection/protection must be enabled. To prevent false activation of protection mode during power mode transitions, interrupts related to supply fault and deflection fault are disabled.

Service Modes, Error Codes, and Fault Finding -Ve Threshold Switch 5. EN 17 Once the XRAY protection status is confirmed, the "PRD" bit has to be set to "1" by software. This enables an automatic stop of the H-out via Slow Stop initiated by auto-clearing the DFL bit. Now, the protection mode is activated.

Service Modes, Error Codes, and Fault Finding 5.8.5 A02U AA 5. EN 19 (first connect ground to measuring equipment, than measure the gate). Main Supply 1. Replace FET 7504 and zener 6505. 2. Disconnect the SSP panel. 3. Short B and E of TS7529, in order to put the Main Supply in "on"-mode (TS7529 is blocking then). Caution: To prevent that R3403 and TS7443 will be damaged, first disable the HW-protection of the deflection circuit. Therefore, short-circuit C2642 on the LSP (diagram A4). 4.

You can find more information on how this procedure works in the ComPair file. It is possible that not all sets are equipped with the hardware, needed to make software upgrading possible. To speed up the programming process the firmware of the ComPair interface can be upgraded.

Circuit Descriptions, Abbreviation List, and IC Data Sheets In the 3D comb filter implementation (for USA only), the 2D comb filter processing in ADOC IC (on the Main-Video path) is disabled via SW. The signal input for the 3D YC comb-filter circuit is derived from the CVBS-SC2_MON-OUT signal path. The processed signal is re-inserted back via YCOMB and CCOMB inputs of the MPIF IC. The 3D Comb filter is integrated in one IC (type uPD64083).
