Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Hi I ve a sony KDL-40W2000 stuck on stdby red light flashing 4 times the stop for 3 second ??any advice please


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Error code e01


do the following steps: God bless you
To start test program, press and hold both POWER SCRUB PLUS and RINSE & HOLD program buttons, then turn unit on by pressing ON/OFF button. When program buttons are released, lights above them will flash. To end test program, press ON/OFF button.To check program indicator lights (POWER SCRUB PLUS, REGULAR WASH and RINSE & HOLD), press and hold each program button. When REGULAR WASH program button is pressed, CLEAN light also comes on.
To start testing, press both POWER SCRUB PLUS and RINSE & HOLD buttons a second time. When testing has ended and a fault was detected, the following indicator lights will be lit:
POWER SCRUB PLUS = Heater fault
REGULAR WASH = Water filling fault (over or under filling)
RINSE & HOLD = NTC (temperature sensor) fault ? note circulation motor stops shortly after it started during an NTC fault
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), REGULAR WASH light will come on and unit will continually fill and drain where testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), RINSE & HOLD light will come on immediately and testing will end shortly after water has started circulating.
If more than one fault occurs, more than one light will be lit.

Year old Bosch SHU33A0UC won't start. Lights on


Light's on mean you have power.

Initiate the self test program by doing the following -

To start test program, press and hold both POWER SCRUB PLUS and RINSE & HOLD program buttons, then turn unit on
by pressing ON/OFF button. When program buttons are released, lights above them will flash. To end test program, press
ON/OFF button.
To check program indicator lights (POWER SCRUB PLUS, REGULAR WASH and RINSE & HOLD), press and hold each
program button. When REGULAR WASH program button is pressed, CLEAN light also comes on.
To start testing, press both POWER SCRUB PLUS and RINSE & HOLD buttons a second time. When testing has ended
and a fault was detected, the following indicator lights will be lit:
POWER SCRUB PLUS = Heater fault
REGULAR WASH = Water filling fault (over or under filling)
RINSE & HOLD = NTC (temperature sensor) fault – note circulation motor stops shortly after it started
during an NTC fault
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil,
measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays
at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), REGULAR WASH light will come on and unit will continually fill and drain
where testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150ºF) and water won’t stop
circulating. If NTC probe (f2/f4) has failed (opened), RINSE & HOLD light will come on immediately and testing will end
shortly after water has started circulating.
If more than one fault occurs, more than one light will be lit.

Let me know what you figure out. I can repair these boards most of the time.

Diagnostic Test Modes Without Scan Tool
Two mode options are available under the diagnostic test modes:
  • user mode.
  • diagnosis mode.
The ignition switch is used to alternate from one mode to another.
Diagnosis Mode
The diagnosis mode will display any fault present in the system. The SRS will not enter diagnosis mode if no malfunction is detected.
User Mode to Diagnosis Mode
NOTE: The SRS will not enter diagnosis mode if no fault is detected in user mode.
  1. Ignition switch to ON.
  1. After the air bag warning indicator lights for seven seconds, set ignition switch to OFF within one second.
  1. Wait more than three seconds.
  1. Repeat steps 1 through 3 three times.
  1. Ignition switch to ON.
Diagnosis Mode to User Mode — After Repair
  1. Ignition switch to OFF for at least one second.
  1. Ignition switch to ON.
Diagnosis Mode to User Mode — During Diagnosis
NOTE: If switch from Diagnosis Mode to User Mode is required while diagnosing a fault, carry out the following procedure.
  1. Ignition switch to ON.
  1. After the air bag warning indicator lights for seven seconds, set ignition switch to OFF within one second.
  1. Wait more than three seconds.
  1. Repeat steps 1 through 3 three times.
  1. Ignition switch to ON.
Clearing Lamp Fault Codes
NOTE: Lamp fault codes must be cleared from memory before proving out the system.
NOTE: When a new RCM is installed, the air bag warning indicator will operate in user mode. Switching to diagnosis mode is not required.
To clear lamp fault codes after a repair, carry out the procedure to switch from diagnosis mode to user mode. Once in the user mode, the lamp fault codes will be cleared from memory.
Lamp Fault Codes
If the air bag diagnostic monitor detects a current fault, the fault code will be displayed with a flashing sequence of the air bag indicator. The fault code consists of:
  • A start signal to indicate the beginning of a fault code.
  • A number of flashes indicating the particular code that has been set.
The start signal:
  • begins with two seconds off.
  • two seconds on.
  • off.
  • one second on.
  • two seconds off.
Following the start signal, if any current fault is detected, the fault code will be displayed. The fault code:
  • is a series of half second flashes of the air bag indicator.
  • is followed by the start signal.
The start signal and the code for any current fault will repeat until the ignition is switched off or the air bag diagnostic monitor is switched to the user mode.
Inspection and Verification
  1. Verify the customer concern by checking the air bag indicator in the instrument cluster. Refer to Prove Out in this section.
  1. Visually inspect for obvious signs of mechanical and electrical damage using the following chart.


Visual Inspection Chart Mechanical Electrical
  • Damaged air bag diagnostic monitor bracket
  • Open fuse
  • Damaged wiring harness
  • Loose or corroded connectors
  • Circuitry open or shorted
  • Damaged shorting bars

  1. If the concern is not visually evident, enter the system Diagnosis Mode.
  1. If no DTCs are displayed in the Diagnosis Mode, proceed to the Symptom Chart in this section.
  1. If DTCs are retrieved, proceed to the Air Bag Diagnostic Monitor Fault Code Table in this section.


Air Bag Diagnostic Monitor Fault Code Table Code Component/Fault Description 0 Normal Operation/No Fault Detected 1 Front Passenger Safety Belt Pretensioner 2 Driver Air Bag Module Circuit Is Faulted 3 Front Driver Safety Belt Pretensioner 7 Air Bag Diagnostic Monitor Fault 8 Passenger Air Bag Module Circuit Fault 9 Low Battery Voltage
