No sound from speakers and display panel blinks all the time.
I bought my avr 2550 second hand. The whole display panel blinks constantly (this surely cannot be right) and there is no 'test signal' sound in speakers either before setting up the analogue CD input or afterwards. I have tried my two existing stereo speakers in every stereo dolby mode. The result is the same.. blinking display and no sound. (I have already reset to factory defaults before all this)
Have I bought a piece of junk or is there a reason for these symtoms? Am I doing something wrong? This was supposed to be a present for my girlfriend and I am despairing here.

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.
once you have cleared the memory in this manner,
it is necessary to re-establish all system configuration
settings and tuner presets.
To reset the AVR's processor:
1. Press the front-panel Standby/On switch for more than three seconds to turn the AVR
off (the Power Indicator will turn amber).
2. Press and hold the front-panel Surround Modes button for at least 5 seconds until the
RESET message appears on the front-panel Message Display.
NOTE: After performing a processor reset, wait at least 1 minute before pressing any
Source Selector buttons.
Turn the unit off by main switch (not a standby button). Press and hold "Speakers-A" and "Speakers-B" buttons and turn on main switch. Display blinks. Release the buttons after 3 seconds. Receiver is reseted.
time to reset the microprocessor. See page 87 in manual.
1) switch off the unit using the main unit's power operation (small power button)
2) hold the PURE DIRECT button and DIRECT button at same time and turn the main unit's power operation on.
3) wait for entire display to flash in 1 second intervals
now the speakers need to be set up again but zone 2 will be working. i suspect a power surge causes the microprocesser to be corrupted. i put a power surge protector and have not had problems (lately).
More than likely the protector circuit is getting activated... You can't go below 6 ohms on the surround back which means you need 12 ohm or higher speakers for outside (since the two outputs for surround back/zone2 are in parallel). As a simple diagnostic test, disconnect one speaker and see if the sound survives longer than 2 seconds.
