When i turned my harman/kardon avr65 it flashes protect on the screen what could b the problem


In most cases this involves the audio output transistors or ic's in the receiver, the auto protector is sensing a short in the load. But lets do a couple of checks, turn down volume all the way, power off, remove all speaker wires from the back, now turn receiver on to see if protect comes back, if no! check wiring for any shorts and connect speakers one at a time leaving the volume down, if you find one that triggers the problem you have found the culprit, on the other hand if protection is triggered with all loads removed this would be a good time to get a technician to assess the situation.

Warning lights blink upon startup, printer freezes


If the lights flash alternately then it is probably your waste ink pads that need cleaning
If the lights flash continuously check your printer for any outstanding documents in the print queue and cancel them then try again

EIKI XB23 PROJECTOR WON'T GO ON


Do you hear the fan start up? or does the projector lamp come on (you start to see an image)?

If yes to either:

When the temperature inside the projector reaches a
certain level, the projector will be automatically shut down
to protect the inside of the projector. The POWER indicator
is blinking while the projector is being cooled down. When
the projector has cooled down sufficiently (to its normal
operating temperature), it can be turned on again by
pressing the POWER ON-OFF button.

Note:
After the temperature inside the projector returns to normal, the
WARNING indicator still continues to blink. When the projector is
turned on again, the WARNING indicator stops blinking.

Then check the matters below:
– Did you provide appropriate space for the projector to be
ventilated? Check the installing condition to see if
ventilation slots are not blocked.
– Is the projector not installed near the ventilation duct of
air-conditioning equipment which may be hot? Install the
projector away from the ventilation duct of airconditioning
equipment.
– Are the air filters clean? Clean the air filters periodically. Let me know if you need to know how to do this.

If no to either:

When the projector detects an abnormal condition, it is
automatically shut down to protect the inside and the
WARNING indicator will be red. In this case, disconnect the
AC power cord and reconnect it, and then turn the projector
on once again for check. If the projector cannot be turned
on and the WARNING indicator emits a red light, disconnect
the AC power cord and contact the service station for check
and repair.

Please let me know if this helped solve the problem. If not, is there anything else you observed - whether or not you believe it's relevant.

Blinking lights list of faults


Not really. There is just the blinking red lights: usually power issue or motherboard issue.

And the YLOD, usually releated to a video chip problem but it's always a hardware defect which causes that one.

Won't turn on


What you have there is a V27 Chassis manufatured in 1999..
But it is the same chassis that was later used in their WS55517 65517 and 73517... Regardless of the outcome here are some common caps that ALWAYS need to be replace:
C979 2.2uf 200v
C531 2.2uf 160v
C551 2.2uf 160v
C981 22uf 50v
C402 47uf 35v

Now to your problem, it could be a number of things. The regulator could be suspect, (Ic951 which is a STRF6628) but you might try the following before taking any gunshot approaches. 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) 1. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB.
Hope this helps!
