1-4. Cleaning
1-4-1. Cleaning of Viewfinder
By extracting VF tube sub assembly, lens and MC protec-tor can be easily cleaned. And also dust on the CRTsurface or mirror can be easily cleaned off.
1. Turn the hold ring to the left and extract the VF tubesub assembly.
2. Detach the eyecup.3. Remove the MC protector with a commercially
available camera lens cleaner. Blow off dust with ablower carefully so as not to flaw the mirror.
4. After the cleaning is completed, install by reversingthe preceding steps. Align red lines of the VF tube andVF tube sub assembly when inserting, and turn thehold ring to the right until it locks.
n• Do not use any type of solvent, such as alcohol, benzine
or thinner to remove stains.• Be sure to attach the eyecup to the VF, or the MC
protector may come off.• To protect the viewfinder lens from drops, put the MC
protector in the filter holder and attach the eyecupsecurely.
1-4-2. Care After Using at SpecialEnvironment
It is recommended to check the following items aftergathering the news at seaside, dust area or spa.
1. Clean off sand and other dust in the unit carefully.2. Do not allow salt in seawater or sulfur in spa to contact
a not-painted surface of the cabinet. They may cause tocorrode. Clean with alcohol immediately if contacted.
3. Clean the connection surface of connectors.4. Carry out the common operation check.

2. Remove the two screws (K2.6 X 5).3. Remove the three hexagonal socket bolts (2.6 X 6) and
remove the upper chassis.4. Disconnect the flexible card wire of the VR-226 board.
(How to disconnect the flexible card wire, refer toSection 1-6.)
5. Disconnect the four connectors CN2, CN4, CN5 andanode cable of the VF-67 board.
6. Remove the three screws and remove the CRT fromthe VF tube assembly.
7. Remove the CRT tube from the CRT.
8. Remove the four screws (K2 X 5) and remove themask spacer.
9. Disconnect the connector CN21 on the LP-101 board.
10. Install a new CRT in the reverse procedures of remov-al.
nWhen installing the upper chassis, take care not toclamp the harness between upper and lower chassis.

1-6. Disconnecting/Connecting FlexibleCard Wire
The flexible card wire is used between the VF-67 boardand VR-226 board. Take care not to break this flexiblecard wire. This shorten the wire life.
Disconnecting
1. Turn off the power.2. Slide portions A in the direction of the arrow to unlock
and pull out the flexible card wire.
Connecting
n• Be careful not to insert the flexible card wire obliquely.• Check that the conductive surface of the flexible card
wire is not soiled with dust.
1. Slide portions A in the direction of the arrow andinsert the flexible card wire as far as it will go with theconductive surface down.
2. Slide portions A in the reverse direction to lock.

Section 2Electrical Alignment
2-1. General Information for ElectricalAdjustment
2-1-1. Notes on Adjustment
1. When performing adjustment, read throughly thefollowing comments.
• The calibration of all measuring equipment should becompleted.
• Peripheral equipment (camera, and others) alignmentshould be completed.
• “2-1-4. Settings for adjustment” should be completed.• Turn off the power before extending the plug-in board
using the extension board.
wThere is a danger of an electric shock around the CRT dueto high voltage. Therefore, do not touch the CRT.Be very careful when service in a live.
2. Change the Picture Frame mode (4:3/16:9)• When the unit is put into the 16:9 mode, set as follows.
1) Extend the AT-95 board of BVP-550 with EX-464extension board.
2) Short between pins 76 and 100 on the EX-464board using a shorting clip.
• When the unit is put into the 4:3 mode, disconnect theshorting clip as above.
