Sharp Aquos LC-30hv4u

Sir GURU-

My Sharp LC-30hv4u won't power up and red led flashes four times and repeats. Can you tell me what error code this represents? Local shop want's $100 to diagnose this problem and I suspect the repair charges will be more than the TV is worth. Please e-mail treid(at)san.rr.com

    The display fits tight in a cabinate and heat builds up behind. It seems like there was a fan noise before but not now. I do not have a surge protector. Is there a vane switch that prevents operation if the cooling fan fails, or it can't get air due to dust in the intake?

  • treid Jul 14, 2008

    I don't have a schematic and I do not know if the power supply lives in the display or in the AVC system. This TV has a lcd display and a separate control box (AVC). It has two cables going from the AVC to the display. I have a concern that this email has been routed to your rear screen projection team. I don't know how that happened.

    HAI,No vertical Deflection (V STOP), Screen goes to a single horizontal
    line then the video signal muted. Check IC1509, Q1505,CAPACITORS.



    Are you saying that the four flashes from the red power led indicates this? There is nothing at all displayed on the screen. No white line. The led comes on green, thinks for about five seconds, then flashes red four times and repeats.

Check power supply secondary outputs.
· If voltages are present and at proper the level, then the problem is in the Vertical deflection drive
circuit.
· If the secondary voltages are low or missing, then the problem is in the power supply.

    4 blink means a repair would range around 150.00

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

    thank you


  • dewan nafees ahmed Jul 14, 2008

    ok make sure that you use a surge protector always for the unit.

    use a external fan and try cooling the unit.

    it works many times.

Sharp aquos tv chevron flashing but tv wont come on


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.

If blinks continue without any pause, the main board is faulty.

What does a blinking orange light on 65" Mitsubishi dlp rear projection TV mean?


Self Diagnostics

The V18 Chassis features Self Diagnostics to aid in troubleshooting problems that may cause the set to

automatically turn off or "shut down." The "Timer/Power ON LED" provides an indication of the sets operation,

and the possible cause of a malfunction.

1. Initial Control Circuitry Check

Immediately after the TV is connected to an AC power source:

• The LED flashes three times ... indicating the Microprocessor has initialized and is functioning

properly.

• If the LED does not flash ... the Microprocessor is NOT functioning.

2. Error Code Operational Check

To activate the Error Code Mode, while the set is OFF, press the front panel "INPUT" and "MENU" buttons

at the same time and hold for 5 seconds. The LED will flash denoting a two digit Error Code.

Note: The Front Panel buttons must be used, NOT those on the Remote Control.

• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.

• The flashing then pauses for approximately 1/2 second.

• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.

Example: For Error Code is "24", the LED will flash 2 times, pause, and then flash 4 times.

3. Error Codes

The Error Code designations indicating a malfunction, or no malfunction, are listed below:

"12" ... indicates no error has occurred.

"21" ... X-Ray Protect circuit.

"22" ... Short Protect circuit.

"23" ... Horizontal Deflection failure.

"24" ... Vertical Deflection failure.

3. Error Code Operational Check

Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational

Check. When the TV is switched Off, the code automatically resets to "12" No Error.



Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem

has occured since the last Initalization.



Note: The front panel buttons must be used, NOT those on the Remote Control.



• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.

• The flashing then pauses for approximately 1/2 second.

• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.



Example: If the Error Code is "23", the LED will flash two times, pause, and then flash three times.

Hi,
Most common problem in WS-55819 is failure of convergence output chips and blown pico fuses in power supply section.
You need to read out error code in tv, procedure is as follows:
Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem has occurred since the last Initialization.
Note: The front panel buttons must used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: If the Error Code is "24", the LED will flash two times, pause, and then flash four
times.
Error codes detail:
The Error Code designations indicating a malfunction, or no malfunction, are listed below:
"12" ... indicates no error has occurred.
"21" ... X-Ray Protect circuit.

How do you retieve the error codes?


All Mitsubishi DLP Televisions have a built in Diagnostic Decoder to store the last fault in memory. This will help the Mitsubishi Technician determine what area or part defect could exsist due to your television not coming on or turning off by itself. In order to read the error code from the front panel lights, you need to know how to access this information if it is available.
Please remember not to unplug the tv from the power outlet because this will reset the error code. The television must be in the power off state or shut off state to retreive the code.
Error Code Operational Check
Note: The TV must be in “Shut Down” and not have been switched Off, to perform the Error Code Operational
Check.
Pressing the front panel “ACTIVITY” and “CHANNEL DOWN v” buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The “TIMER LED” flashes denoting a two digit Error Code, or indicating no
problem has occurred since the last usage.

Note: The front panel buttons must be used, NOT those on the Remote Control. • The number of flashes indicates the value of the MSD (tens digit) of the Error Code. • The flashing then pauses for approximately 1/2 second. • The LED then flashes indicating the value of the LSD (ones digit) of the Error Code. • The Error Code is repeated a total of 5 times.
Example: If the Error Code is “23”, the LED will flash two times, pause, and then flash three times, then this will repeat itself for four more times before the blinking stops. If you forget the code, you can start all over again after the LEDs have stopped blinking. Just remember you are looking for a two digit code, denoted by a pause in the middle.
Example: You are watching Television and after 20 seconds it shuts off with no picture or sound. By pressing on the front panel the INPUT and MENU at the same time starts the Diagnostic Procedure, and the TIMER LED will then blink six times, and then a small pause, then six more times. This is an error code of 66, and will indicate to the Technician a defect in the lamp ignition circuitry. This will help us to order parts for the repairs without guess work.
In addition to the above code retrieval procedure- most new Mitsubishi LCD & DLP televisions have a built in Error Code Log or menu system. To access this feature the television has to be on and have a picture or blue screen to read this fault menu . To read this Error Log in the television you have to use the Mitsubishi remote control and follow this procedure: Press & release the Menu button, followed by 3564 on the remote control. You will see Lamp time, Code & Status. If an error has happened, please read the numbers indicated under Code to our service person or office staff. We can determine by these codes how to handle service on your unit.

I have a Mitsubishi WD-62525. This morning my TV would not turn on so I pressed the rest button. After the Timer light stopped blinking I pressed power. I could hear the fans start than a somewhat loud...


the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
Note:
The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.


and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure

Looking for codes for universal rca rcr430s remote control


You can find the remote control codes for difrent brands of devices from
http://www.hifi-remote.com/ofa/codes-vcr.shtml#dvd

If none of the codes work then we have two other solutions:

1. Searching For Your Code

If you have tried all of the set-up codes for your brand of equipment ,or your brand is not listed, and you are still not able to get the unit to respond, try the following procedure to search for your code.
If you don't find a code that works, the remote will flash four times when you reach the end of all the codes for this device type.
  1. PRESS the button for the device you want to program, (TV, VCR, CABLE, etc.), then RELEASE.
  2. PRESS and HOLD the SETUP button until the red LED flashes twice, then RELEASE.
  3. ENTER 9-9-1 (two blinks on the remote)
  4. ALTERNATE slowly between the POWER key and the DEVICE (TV, VCR, CABLE, etc.) button until your device turns off. (On VCR, LD, and CD players use PLAY instead of POWER)
    Make sure that the remote is pointed at your device during the search, You may have to press this sequences of buttons up to 100 times to search the entire library of codes.
  5. When your device turns OFF, PRESS the SETUP button and RELEASE it to lock in the code for your device.


2. Learn the buttons from the original

Line up your original remote and the head-to-head before completing the following steps.
  1. PRESS and HOLD the SETUP button until the red LED flashes twice.
  2. PRESS 9 - 7 - 5, the red LED will flash twice.
  3. PRESS the DEVICE key where you wish to learn the function. The next 3 steps must be completed within 10 seconds.
  4. PRESS the button that will receive the learned function, the LED will flash radidly.
  5. PRESS the button on the original remote to be learned.

Now you can repeat steps 3 through 5 to learn other functions onto other keys or press and hold SETUP until the Cinema's red light flashes twice to lock in your new feature. (If the red light does not blink twice, stop and repeat steps through 6).
To test the new feature, press and release the device key in which the new feature was learned followed by the key on which the feature was learned
