HI
Try resetting the system . if this doesn't work.
"Service" is needed .
To clear the AVR's entire system memory including
tuner presets, output level settings, delay
times and speaker configuration data.

1: first put the unit in Standby by pressing the System
Power Control button
2. Next press and hold the Tone Mode button 8 for three seconds.
The unit will turn on automatically.
this will clear all the proccessor.
Note that
once you have cleared the memory in this manner,
it is necessary to re-establish all system configuration
settings and tuner presets.

Good luck
Kind Regards

Check your audio settings on the main menu of the receiver. The audio input should be set to "auto" Next, make sure you don't have the unit in "6 channel input" mode or "direct" mode. This is usually a small button on the front panel. If you check all this and you still have a problem, post a comment and I will help you troubleshoot some more. Hope this helps

My 2hp Panasonic is blinking when turn on and the compressor stop working while the outdoor fan will be blowing cool air.


1. Turn power on.
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. The power LED lights up. If no abnormality is
stored in the memory, three beeps sound will be
heard.
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.

Lg 50pc55 plasma- has sound but no display??


Quite possible-----replace all bad ones and also if possible the voltages coming out of that board need to be tested---to be honest other than the caps it sounds like a main board issue. The set may have been run too long with the bad caps.

My best "guess" based on description is either the main board or the display panel itself is bad.

It sounds like you digital assignments are either hosed or not working. Most AV receivers will TRY the digital path first and drop to an analog path if the bitstream is absent or corrupt. Upon restortation it might switch back automatically.

Treat it like a new installation and thumb through the manual and settings.

Refrigerator temperature control panel not lit. This happened last week but corrected itself....not sure how....but now display panel is off for good, it seems. Main Refrigerator lights are still working,...


Your Refrigerator Has a main controlboard located in the rear of the machine. This Controlboard sends power and reads the user information. if your user display (Temp Control panel) is not working it can only be 2 things The user display or the main controlboard.

As far a the refrigerator working without it, I would not trust it.

The clicking noise is a relay on the main control.
Usualy when I here this relay go on and off rapidly, there is a problem whith the main controlboard.

The big problem with this is why did the main control go out ? some other componet on the refrigerator could be the cause. A comon cause in the past has been the evaperator fan motor.

BLANK DISPLAY AND CLICKING SOUND


This is the main control board failing. My symptoms were identical (intermittent display and clicking), and eventually the clicking didn't go away and the freezer got hot. I replaced the main board yesterday and all is well (display fixed and no clicking). I was able to find the correct part number using the GE website (entered refrigerator model PD22S1S and then selected PDS22S1SARSS from the drop-down list). My part number was WR55X10656. The GE price was shown as $157.50, but I bought mine from ApplianceZone.com for $101.68. Hope this helps.

The retuning process is as follows:

  1. Press the [i+] or MENU button on the remote control to display the DIGITAL INFO menu.
  2. Press the BLUE button to display the MAIN MENU.
  3. Press the UP or DOWN buttons to highlight AUTO TUNING then press the OK button to display the AUTO TUNING MENU.
  4. Press the RED button to start the auto tuning process for all available digital channels.
  5. Wait for the process to complete.

If you wish to CANCEL the auto tuning process whilst it is processing then press the BLUE button at any time.

You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information

http://www.freeview.co.uk/_retuneinfo/

If the above process does not work then check the link above for additional information and also visit the accompanying site links below to find more information for your model of TV / FREEVIEW box.
