Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of soldering iron around 270˚C
during repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.

SECTION 1
SERVICE NOTE
The TCS-60DV detects rotation of both the supply and take-up side
reels using the PH701 (photo reflector). Because the PH701 is
mounted on the Main board, auto stop is activated and reel rotation
cannot be detected when the Main board is removed. To check the
operation of mechanism deck and voltage without the Main board,
follow the procedure as described below.
How to remove the Main board (opening the Main board)
1) Refer to page 5 “3. Disassembly”.
How to enter the fast forward/rewind modes
1) Input the square wave to the TP41. (Refer to the illustration
below.)
2) Press the fast forward/rewind keys.
3) Turn on the S301.
How to enter the playback mode
1) Input the square wave to the TP41. (Refer to the illustration
below.)
2) Press the playback key.
3) Set the S302 to the PLAY.
4) Turn on the S301.
How to enter the record mode
1) Input the square wave to the TP41. (Refer to the illustration
below.)
2) Press the record key.
3) Set the S302 to the REC.
4) Turn on the S301.
