A reading leak occurs in the continuation code of the Remote Controller. (It is especially UP / DOWN of the Volume.)
[REASONS]
The protection circuit operates by Impulse Noise.
[SOLUTION]
1.POS.NO R564 RESISTOR (47K OHM) is changed to RESISTOR 15K OHM +-5% 1/6W (Part no. 00MGD05153160 ) on the VIDEO PCB.
R564
[NECESSARY PART]
POS.NO R564 00MGD05153160 (15K OHM +-5% 1/6W)
This is “nsp” part, MARANTZ will not supply this part.
[REMARKS]
1. This problem apply to the following serial number.
SR4500/N1S |
MZ000426000001 to MZ000426000520 |
SR4500/N1G |
MZ000426000001 to MZ000426000628 |
2.This improvement has been done in the production serial number MZ000430xxxxxx and after.
