SOURCE: My Panasonic SC-A240 shuts down displaying the error f61.

Several components in the power supply maybe faulty, especially Tranisitor Q5110, Resistor R5114 and Diode D5102 on the power supply board. Check and replace these and also resolder the regulator IC's on the heatsink.

SOURCE: Toshiba Satellite M30 display problem

I decided to read this and I am not exactly 100 sure what the proplem is. I did want to offer a suggestion though. If you are having problems with both the screen and an external monitor, the problem may be with the graphics hardware. If you have a card, it may need to be replaced. If not, i'm very sorry. The motherboard may need to be replaced. Hope this helps.

SOURCE: My nc8000 shuts down after few seconds and starts after power plugged in or battery inserted

Hi Turecki, It's a moderately easy fix for this common issue with HP/Compaq Laptops. Simply go to ebay, purchase an "inverter" board built for a NC8000 laptop can range from $10-$50 just purchase one with a minimum 6 month warranty. Its about a 0.5 inch by 15 inches. Unscrew all of the tiny phillips screws located and hidden behind black rubber covers on the LCD screen. Pop off the plastic LCD cover and replace the inverter board located at the bottom of the LCD (plug & play). Put it all back together and voila...problem fixed.

Have fun and practice some repair skills.

How do you reset the infinity? where the power button?


Hi,
Most car audio amplifiers don't have on off switches.
So to reset the amplifier, disconnect it from the power source, from the car battery side.
Disconnect the positive side (red) first. Then the negative side (black)
Or sometimes its easier to remove the fuse next to the battery for the amplifier.
After its disconnected leave it disconnected for approx 5-10 min.

I hope this helps

In my display is says 3-03 when ever i plug in my rca cables and no sound comes out?


From Page 7 of your manual... this is indicating a grounded speaker wire (blown voicecoil).

It has shut down to prevent damage. Disconnect the speaker wires from the amplifier and power on the amplifier again. If the error persists - you will need to have the amplifier repaired.

Check the voicecoils for proper imedance.

Stereo amplifier shutdown.


  • The amplifier is showing the protect mainly due to a safety feature on the power circuit. The fault could be failure or short in the output stages, short in the speakers, fault in the power ciicuit or the error amplifier that triggers the relay.
  • To trace the fault it is impotant to make the test in the main board, disconnect the power to output to confirm if the output is faulty. similarily disconnect the powering circuit one by one to identify. replace or disconnect to confirm. Hope this helps. Good day

INFINITY AMP PROTECTION LIGHT FLASHING


Overload maybe. If the amp is run at an improper impedence, the amp will shut down. If you are "CLIPPING" speakers / subwoofers the light will blink to indicate a hard clip . Example: 4ohm/2ohm stable amp with 4 ohm subs wired at 1 ohm.

Protection Mode? amp wont start


With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.


If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
