Following a power cut, my HL2142 has all lights flashing. Can't fix it. Help.


A power surge most likely damaged your printer. Printers are a cheap item and getting it repaired would most likely not a cost effective solution.
To prevent power surge problem you need to connect all your computer equipment and printer to a power board with a built-in surge protection then plug this power board into the mains outlet.

Running four S70 Siroccos off the amp, everytime volume gets halfway the protection is cutting in with protection light flashing three times? When reducing down to two speakers amp cuts out three quarters...


You are overloading your amp. IMO 640A cannot handle heavy loads.

Better change the speaker combo and connect something that puts right load on the 640A. Else, get a meaty amp from CA.

Remove write protection from micro-sd card


  1. Remove the Sandisk SD card from your portable electronic device. Ensure that the SD card can be safely ejected before removing.
  2. Locate the write protect lock. The write protect lock should be on the side opposite the cut-off corner of the SD Card.
  3. Disengage the write protect lock. To do this, gently slide the small switch upward, toward the top of the SD Card. The card should now have write protection disabled.
jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); });

My tv will not turn on the power light comes on


After the power surge , the TV went on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur after power surge on a rear projection are a blown capacitor on power board, a component on ballast board has blown, or a fault on Digital board had occurred.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Cutting out intermittent problem


If the voltage is dropping to 8v, it sounds like there is a problem with either the B+ line or the ground connection. You should also check the voltage across the battery terminals to see if the voltage is dropping at the source.

The amp may be going into protect mode. Disconnect all speaker wires from the amplifier's terminals. Also disconnect the RCA cables from the amp. Does it still go into protect?

Insert a 20 amp fuse in the B+ line and try to power it up. If the fuse blows with no speakers connected to it, the amp probably has a blown channel.

Vollume trouble


the system protect is usually displayed when a condition of short or shorting is occurring in the speaker wiring or the voice coil of any of your speakers.... thte circuit of you reciever is trying to protect itself and you from a very costly repair,,,so it you have another set of speakers try to use them and see if the condition still exists and if it does the problem is in the output section of the receiver,,,and if the protect no longer exists you have fixed your problem,,,good luck
