Possibly, check error codes for problems:
• To make a diagnosis
1. Timer LED start to blink and the unit automatically stops the operation.
2. Press the CHECK button on the remote controller continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display. Note: Display only for "- -". (No transmitting signal, no receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote controller. The code "H00" (no abnormality) will be displayed and signal will be transmitted to the main unit.
5. Every press of the button (up or down) will increase abnormality numbers and transmit abnormality code signal to the main unit.
6. When the latest abnormality code on the main unit and code transmitted from the remote controller 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. The breakdown diagnosis mode will be canceled by pressing the CHECK button continuously for 5 seconds or without any operation the remote control for 30 seconds.
8. The LED will be off if the unit is turned off or the RESET button on the main unit is pressed.

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

No picture for ps3,i went to service menunand did something wrong


You probaly turned hdmi on or off i dont know what your settings is,

you can turn your system settings back to factory default using the Safe Mode.

Step 1: Turn off the PLAYSTATION 3 by holding the Power button on the front of the unit till the Power light is red.

Step 2:
  1. Touch and hold the Power button, you will hear the first beep, meaning the PLAYSTATION 3 is powering on.
  2. Continue to hold the Power button and after about 5 seconds, you will hear a second beep, indicating the video reset.
  3. Continue to hold the Power button and after about another 5 seconds you will hear a third beep and the system will power off (Power light is red).

Step 3:
  1. Touch and hold the Power button, you will hear the first beep, again for the PLAYSTATION 3 to power on.
  2. Continue to hold the Power button and after about 5 seconds, you will hear a second beep for video reset.
  3. Continue to hold the Power button and after about another 5 seconds you will hear a quick double beep. At that point release the Power button. If you succeeded in activating Safe Mode, you will see a message on the screen saying, "Connect the controller using a USB cable and then press the PS button."
  4. Connect a USB cable to the controller and the PLAYSTATION 3 and press the PS button to enter Safe Mode.
  5. Then you will see the Safe Mode menu.

Step 4: We recommending performing the safe mode options in the following order until one of the options works for you. If one of the options work, do not continue onto the other options.
  1. Restore Default Settings
  2. Restore File System
  3. Rebuild Database
  4. Restore PS3 System

Hissing sound from a Panasonic old TV...Sound and picture are OK. The hissing sound even continues when the MUTE on the Box is ON. The hissing only stops when the MUTE on the TV is ON. I am using the...


If you disconnect or power off the converter box does the hiss go away?
If you connect a VCR or DVD player does it still have the hiss? We
need to isolate what source is causing the hiss if it is from the set or
if it is from the converter box.
When you turn the volume control down on the set, does the hiss
reduce in level? If mute stops it, it should reduce in level as you
turn the volume down. Then turn up the sound level control on
the converter box whether its a manual control or by remote. If you
can get a combination that minimizes the hiss and gets higher sound
level from the programming that may cure it.
I am not familiar with the converter box you are using. Are you using
Audio/Video cables from it to the set or is it coming out with coaxial cable
and used on a channel? If you are using a very old set with a tuner input
perhaps the fine tuning is out of adjustment.

Sony KV-20FS120


It's normal for new sets, especially Sonys to do that due to some sort of gas build-up in the new tube. My set still gets a high-pitched buzz after power on and lasts for a minute or two before silencing. If the hissing continues when the TV is turned off return it to the shop ASAP. It could be a problem with the power supply, something getting ready to blow up. Good luck
