Safety Instructions, Warnings, and Notes 2.4.2 Schematic Notes • • • • • • 2.4.3 All resistor values are in ohms, and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 kohm). Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ohm). All capacitor values are given in micro-farads (µ= x10-6), nano-farads (n= x10-9), or pico-farads (p= x10-12).
EN 6 2. L03.1U AA Safety Instructions, Warnings, and Notes In case of doubt whether the board is lead-free or not (or with mixed technologies), you can use the following method: • Always use the highest temperature to solder, when using SAC305 (see also instructions below). • De-solder thoroughly (clean solder joints to avoid mix of two alloys). Caution: For BGA-ICs, you must use the correct temperatureprofile, which is coupled to the 12NC. For an overview of these profiles, visit the website www.
Push the round end of the adapter (or antenna) onto the 751 (ohm) plug on the back of the TV. If the round end of the antenna wire is threaded, screw it down finger tight. 2 c CHECK IT OUT Use the AutoProgram Control to add all available channels into the TV’s memory, then press the CH + and – buttons to scroll the channels. 1 Connect the open end of the round Cable Company supplied cable to the 751 input on the TV. Screw it down finger tight.
2 3 HELPFUL HINT Reattach the battery lid. Place the batteries (2-AA) in the remote. Be sure the (+) and (-) ends of the batteries line up correctly (inside of case is marked.) Remove the battery compartment lid on the back of the remote. You can also press the STATUS/EXIT button (on the remote) to see what channel the TV is ON. Remember, the tuned channel number will always briefly appear when the TV is first turned ON (and with channel changes.
2 c CHECK IT OUT Press the PLAY button on the accessory device to view playback, or to access the accessory device (camera, gaming unit, etc.). Press the AV button on the remote control to tune the TV to the side input jacks. “Front” will appear on the TV screen. Turn the TV and the accessory device ON. Note: The Audio/Video cables needed for this connection are not supplied with your TV. Please contact your dealer or Philips at 800-531-0039 for information about purchasing the needed cables.
Turn the VCR (either one or two) or accessory device and the TV ON. 5 6 c CHECK IT OUT 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. Note: The Audio/Video cables needed for this connection are not supplied with your TV. Please contact your dealer or Philips at 800-531-0039 for information about purchasing the needed cables.

When ANTENNA is selected, channels 269 are available. When CABLE is selected, channels 1-125 are available. HELPFUL HINT Press the CURSOR RIGHT button to start the Auto Program scanning of channels.
HELPFUL HINT When finished, press the STATUS /EXIT button to remove the menu from the TV’s screen. Press the CURSOR UP ▲ or DOWN ▼ buttons to select and adjust other Picture Menu controls. Press the CURSOR RIGHT or the CURSOR LEFT buttons to adjust the selected control or to make selections for the choose control. Press CURSOR UP ▲ or DOWN ▼ buttons to scroll the Picture features and highlight the control you wish to adjust (Brightness, Color, Picture, Sharpness, Tint, Color Temp.
Note: The Expand 4:3 format can also be activated using the CURSOR UP or DOWN buttons when the onscreen menu is not being displayed. Pressing these buttons will toggle the standard 4:3 format and the Expand 4:3 format. When finished, press the STATUS /EXIT button to remove the menu from the TV’s screen. Press the CURSOR RIGHT or CURSOR LEFT buttons to select one of the two options 4:3 or Expand 4:3. 4:3 - Standard format for the TV.
The screen will ask you to enter a “New Code.” Enter a “new” 4 digit code using the NUMBERED buttons. The screen will then ask you to CONFIRM the code you just entered. Enter your new code again. “XXXX” will appear when you enter your new code and then display the AutoLock menu options. “INCORRECT CODE” will appear on the screen, and you will need to enter 0, 7, 1, 1 again. Using the NUMBERED buttons, enter 0, 7, 1, 1. “XXXX” appears on the Access Code screen as you press the numbered buttons.
CLEAR ALL will not work with the Movie and TV Ratings. These options must be reset individually. If you tune to a blocked channel and enter your Access Code to view the channel, ALL blocked channels will be viewable until the TV is powered OFF and then turned back ON. When the TV is powered back ON, the previously blocked channels will be blocked again. HELPFUL HINT When finished, press the STATUS /EXIT button to remove the menu from the TV’s screen.
HELPFUL HINT Use the CURSOR RIGHT button on the remote to turn the rating option ON or OFF. Press the CURSOR UP ▲ or DOWN ▼ button to highlight any of the Movie Ratings options. When highlighted, all these options can be turned ON (which will allow blocking) or OFF (which will allow viewing). Press the CURSOR RIGHT button to display the MOVIE RATINGS options (G, PG, PG-13, R, NC17, or X). Press the CURSOR UP ▲ or DOWN ▼ button to highlight the words MOVIE RATINGS.
When highlighted, each feature can be turned ON or OFF using the CURSOR RIGHT or LEFT buttons on the remote. Press the CURSOR UP ▲ or DOWN ▼ buttons to highlight the desired feature. Press the CURSOR RIGHT button to display the Blocking Options (BLOCKING, UNRATED, or NO RATING) menu.

Service Modes, Error Codes, and Fault Finding You do not have to know anything about I2C commands yourself because ComPair takes care of this. 3. ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available. When ComPair is installed together with the Force/SearchMan electronic manual of the defective chassis, schematics and PWBs are only a mouse click away. • • • • • 5.4.
