2. GENERAL DESCRIPTIONS

2.1. SERVICE INFORMATION

2.1.1. MICROPROCESSOR RESET

When the Microprocessor IC6001, MAIN C.B.A. and/or Back-up Battery B6001 are replaced, read following procedure carefully and proceed it.

Reasons:

There is a RAM in the IC6001, which is backing up:

1. TV Tuning Data.

2. PG shifter Adjustment Data

3. Option Setting Data

When IC6001, MAIN C.B.A. and/or Back-up Battery B6001 are replaced, all above listed data become not available. These data are backing up by using the power source of: AC connected: AC Power source AC Disconnected: Back-up Battery B6001

Method:

Before replacing IC6001, MAIN C.B.A. and/or B6001:

1. Take a note that stored TV broadcasts channels.(Because , its user may store TV broadcasts by manually other than "Auto Tuning" operation and it is also erased.)

After replacing IC6001, MAIN C.B.A. and/or B6001:

1. Turn on the VCR.

2. Connect a jumper wire between TL7509 and TL7510 for 1 second to reset IC6001.

After resetting IC6001:

1. Store TV broadcasts channels by Auto/Manual Tuning using the On Screen Display according to note which taken before replacing IC6001, MAIN C.B.A. and/or B6001.

http://cxema.ru

2. Set the Direct Rec function to OFF using On Screen Display if necessary. / (Because, Direct Rec function is set automatically to ON after resetting IC6001.) / [Direct Rec Function] / OFF: Normally set at this position. / ON: This setting enables Direct Rec. / AV1 Input(A1) becomes exclusive channel for Direct Rec.

3. Perform the PG SHIFTER ADJUSTMENT. / (Refer to the Electrical Adjustment Procedures.)

Note:

1. It should be performed before tuning.

2. Do not cut off the power source during reset.
