(Color bar signal waveform is described below. Refer to Fig. 2-2-1)
Relay Jig J-6090-036-A : 7-wire flat cable for VP-1 PWB assembly (SLV-L45AR)
J-6090-019-A : 12-wire flat cable for VP-1 PWB assembly
(SLV-L65HFAR/L75HFAR)
RELAY JIG
Connect the flat cable end from the cylinder assembly to
the VP-1 PWB assembly using the relay jig to provide
simple repairing of the VP-1 PWB assembly, as shown in
Fig. 2-2-3. Further, when adjusting the VP-1 PWB assem-
bly, be sure to make contact an end of shield case with
bracket of the VP-1 PWB assembly to maintain the shield
effect. If the VP-1 PWB assembly does not contact, there
is insufficient ground and no proper play back image can
be obtained.
