Procedures To Be Taken When The Rpn Compensation Fails - Sony Power HAD FX HSC300R Service Manual

1. Select the channel (R, G, or B) to be compensated.
ITEM: RPN CH SELECT → R, G, B
2. Adjust the H and V values and set the cross cursor center at the target RPN.
When the cursor is placed accurately at the RPN position, the RPN is compensated.
Note
Some RPNs seem to have been compensated even if the cursor is placed off the RPNs by one line or one pixel.
Before proceeding to step 3, shift the cursor by one line or one pixel and check that the compensation position is
correct.
ITEM: RPN CURSOR → ON
ITEM: CURSOR H POS.
ITEM: CURSOR V POS.
Tip
One click of the rotary encoder is equivalent to one-pixel shift.
On the other hand, the cursor moves by two clicks of the rotary encoder because the cursor has a size of two pixels.
3. Press the rotary encoder and record the RPN data (correction value).
ITEM: RECORD RPN → EXEC
4. A message "RECORD DATA OK? YES → NO" appears.
Check that the RPN has disappeared and then select "YES" with turning the rotary encoder.
5. Press the rotary encoder. A message "COMPLETE!" appears and the RPN compensation starts.
Tip
If a compensation pixel has been wrongly recorded, delete the RPN data.
ITEM: DELETE RPN → EXEC
6. Repeat steps 2 to 5 to compensate other RPNs.
If any RPN still remains after this manual adjustment, handle it according to the flowchart in
Compensation Flowchart".
Setting after Adjustment
ITEM: RPN CURSOR → OFF

Procedures to be Taken when the RPN Compensation Fails

When the RPN compensation is not successful even after the manual RPN compensation adjustment was made, the
following causes are possible.
• An adjacent wrong position was compensated.
• The compensation failed due to the influence of other RPNs.
• The RPN with a very large level has an extent over one pixel that was made in the signal generation process.
