REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

MARANTZ PM11S1 SERVICE MODE ERROR CODES AND POWER AMP CIRCUIT

MARANTZ PM11S1 SERVICE MODE ERROR CODES AND POWER AMP CIRCUIT

MARANTZ PM11S1 

SERVICE MODE ERROR CODES AND POWER AMP CIRCUIT 

Adjustment Procedure
Set the power voltage to rated voltage for this adjustment
DC Offset Voltage Adjustment
ALIGNMENTS

1. Before turning on the power, Insert Digital Voltage Meter between the SPEAKER SYSTEMS A (L CH) “+” and “–”. Insert Digital Voltage Meter between the SPEAKER SYSTEMS R (R CH) “+” and “–”.
2. Turn on the power, VOLUME is set as -∞.
3. Press the SPEAKER A button.
4. After turn on the power and 2 minutes pass, first L CH is adjusted.
The variable resistor R608 on P601 is turned with adjustment driver, and the Digital Voltage Meter is adjusted to “0mV±3mV”.
5. Then, R CH is adjusted.
The variable resistor R708 on P701 is turned with adjustment driver, and the Digital Voltage Meter is adjusted to “0mV±3mV”.
Idling Current Adjustment

1. After DC Offset Voltage Adjustment is completed, adjust the Idling Current with the variable resistor R619 and R719 on the PCB (P601/P701).
2. Turn off the power.
3. “+” of Connect Digital Voltage is connected to the No. 1  pin and connected “–” to No. 3 pin of J653.
4. “+” of Connect Digital Voltage is connected to the No. 1 pin and connected “–” to No. 3 pin of J753.
5. Before turning on the power, R619 and R719 have been counter clockwise turned with the adjustment driver.
6. Turn on the power, VOLUME is set as -INFINITY .
7. With seeing the digital voltage meter turn the variable
resister clockwise slowly to adjust the idling current.
# Idling adjustment with R619 (R719).
# Turn R619 (R719) clockwise to increase the idling current.
# The adjustment value of idling current is 11mV(55mA) ±0.5mV(2.5mA) each.
8. After 2 minutes, repeat the same procedure as 7.
# Turn R619 (R719) clockwise to increase the idling current.
# The adjustment value of idling current is
11mV(55mA) ±0.5mV(2.5mA) each.
Adjustment is completed.
9. Remove connection cable, attach the top cover. (Idling current decreases with the temperature rise inside the unit, and it is set to 10mV (50mA) of setting value in about 30 minutes after turn on the power.)
SERVICE MODE / TRIM CHECK MODE
1. To enter the Service Mode, press the POWER ON/OFF button with pressing the DISPLAY and ATT buttons to turn on the unit. Or when the remote code “166363” is received while power is ON. When into the Service Mode, the memory is cleared and the unit is initialized.
