Question about Sharp XL-MP130 CD Shelf System

1 Answer

Timer light blinks ....- (four shorts and a long). Unit unresponsive to all buttons. Resetting doesn't help. Condition resulted from a sequence of 4 (four) 1-second house power interruptions/restarts while unit was in standby (as off as it gets without unplugging). All 5 fuses on power supply board appear OK.

    The unit has been unplugged for a month, but starts with the blinking red light as soon as plugged in. I have tried all the manual suggestions. The reset procedure does not work: I assume that means that the system is either not in "standby" (but it cannot be switched into any other mode), or that somehow the power surges did sometning. Sharp wouldn't tell me what the pulse code means, and a local Sharp store told me that it would cost me 2-3 days and $20 plus two trips to their store to have them look at it. The screen never lights up, and only the ". . . . _" (four short timer pulses, followed by a long pulse) can be seen. The power supply puts out 6 and 12 volts.

    If you have access to the repair/servicing manual, or web access like the store to the pulse code list, I'd know what to do with the unit.

First, try unplugging the unit for a couple of hours. That should reset the internal microprocessor. If that fails, try pushing all of the buttons one at a time. If one of them is stuck, nothing will work properly. You should be able to feel the button working.

There is also a reference in troubleshooting in the manual between page 37-39 which i assume you have already consulted. It does recommend turning off and unplugging for up to 5 hours and then reconnecting and using the button sequence to clear memory.

    I am trying to contact SHARP SERVICE Center currently to see if I can get someone to provide me witrh this code. if you respond to this posting i can reconnect to you.for another 30 mins

    OK here it is right from Sharp's service center support.
    The unit is reporting power surge and if the usual unpluging does not fix it then there is damage to the power unit. I mentioned that alll fuses were OK but they still say that the fuses being intact does not eliminate the supply from damage

    The flashing lights are operating from the low voltage part of the power supply but the main transformer is what is damaged. The buttons are operated from this transformer and as they do not respond then this is the area of damage to the supply.The unit will have to be taken to a service center.

    If you are in Australia check a service centre near you from here

No power on (LCD27TV006HD)

Hi,

Does the standby light continue to blink? IF so, count the number of blinks and go to:


Continuous Blink Once A Second, No Pausing As Discussed Above---
No reply from the jungle IC301 (data bus is busy, shorted to ground or held high), IK video path is defective.

ONE Blink--- not used for the self-diagnosis

TWO Blinks---B+ over current protection (OCP) , unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

THREE Blinks---B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

FOUR Blinks---No Vert. Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505

FIVE Blinks---AKB circuit (AKB), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking, try turning up screen slightly.

SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.

SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

EIGHT Blinks---Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401 and 402.


That may help you decide what is going on.

In the long run you will probably need to have a tech take a look at it. The problem you describe is usually a serious matter that needs repair by a trained technician..

Goodluck,

Hi I have a panasonic split air conditioner. It turns itself off immediately after turning on, the timer button then flashes and that's all.... I have checked for an error code it is H00. I have also made...

Hi Tania,
Have you gone through this checking sequence.? it's from a Panasonic a/c manual. It could be something as simple as a clogged filter. Once you have rectified the fault, you will probably have to clear the fault code as described at bottom below, before it will condescend to work again.

  • Once error occurred during operation, the unit will stop its operation, and Timer LED blinks.
  • Although Timer LED goes off when power supply is turned off, if the unit is operated under a breakdown condition, the LED will ON again.
  • In operation after breakdown repair, the Timer LED will not blink. The last error code (abnormality) will be stored
    in IC memory.
14.2.2 To Make a Diagnosis

  1. 1 Timer LED starts to blink and the unit automatically stops the operation.
  2. 2 Press the CHECK button on the remote control continuously for 5 seconds.
  3. 3 "- -" will be displayed on the remote control display.
    Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
  4. 4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed and signal will be transmit to the main unit.
  5. 5 Each press of the button (? or ?) will increase error code number and transmit error code signal to the main unit.
  6. 6 When the latest abnormality code on the main unit and code
    transmitted from the remote control are matched, Power LED will
    light up for 30 seconds and a "beep" sound (continuously for 4
    seconds) will be heard. If no codes are matched, Power LED will light up for 0.5 seconds and no sound will be heard.
  7. 7 The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5 seconds or operating the unit for 30 seconds.
  8. 8 The LED will be off if the unit is turned off or the RESET button on the main unit is pressed.
14.2.3 To Display Memorized Error Code (Protective Operation)
  1. 1 Turn power on.
  2. 2 Press the CHECK button on the remote control
  3. 3 "- -" will be displayed on the remote control display. Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
  4. 4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
    and signal will be transmit to the main unit.
  5. 5 Each press of the button (? or ?) will increase error code number and transmit error code signal to the main
    unit.
  6. 6 When the latest abnormality code on the main unit and code transmitted from the remote control are matched,
    Power LED will light up for 30 seconds and a "beep" sound (continuously for 4 seconds) will be heard. If no
    codes are matched, Power LED will light up for 0.5 seconds and no sound will be heard.
  7. 7 The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5
    seconds or operating the unit for 30 seconds.
  8. 8 The same diagnosis can be repeated by turning power on again.
14.2.4 To Clear Memorized Error Code after Repair (Protective Operation)

  1. 1 Turn power on (in standby condition).
  2. 2 Press the AUTO button for 5 seconds (a "beep" sound is heard) on the main unit to operate the unit at Forced Cooling Operation Mode.
  3. 3 Press the CHECK button on the remote control for about 1 second with a pointed object to transmit signal to
    main unit. A "beep" sound is heard, and the Error Code is cleared

Overhead light will not come on when door is opened

Press and hold the Lock button until the light blinks (about 10 seconds). A single blink indicates that the timer is reset to 1 1/2 minutes. Repeat the procedure and the light will blink twice, resetting the time to 2 1/2 minutes. Repeat again for a 3 1/2 minute interval, etc. up to a maximum of four blinks and 4 1/2 minutes.

Blinking ''comp'' light and unit unresponsive

without knowing that brand of unit as i don't think they are sold in Australia, I think that the system will have lost its' gas charge. If you remove the small nut cap where the gas pipes enter the outside unit and depress the Schroeder valve, and you have little or no pressure released, then you have a leak on the system.

When our garage door opens, my light turns off immediately. How do I get it to stay on for about 5 minutes?

Try this:

Press and hold the Lock button until the light blinks (about 10 seconds). A single blink indicates that the timer is reset to 1 1/2 minutes. Repeat the procedure and the light will blink twice, resetting the time to 2 1/2 minutes. Repeat again for a 3 1/2 minute interval, etc. up to a maximum of four blinks and 4 1/2 minutes.

The light stays on for a long time although it shuts off (a lot more that 4.5 minutes). Can this be adjusted to be shortened? Where and how on the unit?

If you have one of the newer models the duration can be changed by holding in the lock button until the light blinks (about 10 seconds.) A single blink indicates that the timer is reset to 1½ minutes. Repeat the procedure and the light will blink twice, resetting the timer to 2½ minutes. Repeat again for a 3½ minute interval, etc. up to a maximum of four blinks and 4½ minutes.

If your opener has the motion sensor feature and a person enters the garage and walks in front of the door control the light will come on for 5 minutes and then shut off.

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.
