My fosgate amp was workin an now it wont trun on can u help me out plzzzzz.....thanx for ur time...


First check your fuses, all fuses. Then check to see if it's getting voltage to it, look to see if any of the LEDs are lit up, power, protection (over /under voltage, overload (short)) or none. If the power LED is lit & no others then check your RCAs coming into the amp by replacing them or using a multimeter set to ohms to make sure they are not loosing a connection due to wire breakage inside the casing. Cheap RCA's will easily disconnect inside the plug just from twisting them. If they are good and are not disconnected from the head unit, then check your speakers for damaged coils or loose wires, who knows they may have fallen off? If your amp has more than just power LED lit then you may have a short in your speakers or wiring disconnect the wires to see if the protection LED goes away. if not and it's still lit then repair the amp. If there are no LEDs lit at all, check your remote turn on wire from your head unit to make sure it sends out a 12 volt signal to the amp. You can also jumper a wire from the 12v battery connection over to the remote turn on connection to see if it will power up. If not then check power wires and connections, fuses, Battery , alternator, voltage regulator, etc.. any thing that has to do with your cars electrical system may have fried from the current draw by your amp.

My Sony Bravia HX8/46 will not turn on, I check all the power going to it and it all works. Is there something I can do?


Is the standby led on the front lit. If not likely the problem is with power supply. If the standby led is on does it go off when the power button is pressed? Does the led blink. If so count the blinks and get back. The power supply provides an standby voltage to the main board. If the standby led is lit then this voltage is present. When the power button is pressed the micro sends a turn on voltage to the power board. Normally the power supply will respond and all other voltages needed to operate the set will come up. if a component is shorted the micro will not turn on the power board and will usually give a failure code via the standby led.

The SCR lower board is designed with diagnostic LED lights. The LED's are color coded according to
their specific function. Green indicates a properly operating treadmill; the green lights should always
be ON when power is supplied to the treadmill. Yellow indicates a treadmill function. Red indicates a
treadmill malfunction. Here is a list of each LED and what it signifies:
MOTOR (yellow) - The MOTOR LED illuminates when dc (direct current) voltage is sent to the drive
motor. The LED gets brighter when the dc output is increased.
RLC (yellow) - The RLC (R = Reactance / L = Inductance / C = Capacitance) LED illuminates when
the filtering system is properly working. The filtering system includes the capacitor and filter choke. If
there is a short in either component then the RLC light will not come on.
DN & UP (yellow) - The DN and UP LED lights tell us if the elevation DN and UP relays are
functioning properly. When the LED lights, it tells us that the relay has energized and is sending high
voltage (110vac or 220vac) to the elevation motor.
AC PWR (green) - The AC PWR (Alternating Current Power) illuminates when AC line voltage is
delivered to the treadmill. It then passes through the in-line fuse (110)/s(220) and lights the AC PWR
LED.
+12V (green) - When the proper AC voltage is delivered to the treadmill, passes through the in-line
fuse/s, through the full wave bridge rectifier (changes AC to DC), through the transformer (steps down
DC to +12vdc) then the +12V LED lights.
This the board LED, who control the signal for Main Motor+Elevation Motor. You must see, the LED DN+ UP( both will be Lit) in any position down or Up.
2) The RELAY board is designed with diagnostic LED lights. The LED's are color coded according to
their specific function. Green indicates a properly operating treadmill; the green lights should always
be ON when power is supplied to the treadmill. Yellow indicates a treadmill function. Red indicates a
treadmill malfunction. Here is a list of each LED and what it signifies:
AC PWR (green) - The AC PWR (Alternating Current Power) illuminates when AC line voltage is
delivered to the treadmill. It then passes through the in-line fuse (110)/s(220) and lights the AC PWR
LED.
VDC (green) - The VDC LED will light when it receives DC voltage from the DC power supply.
DN & UP (yellow) - The DN and UP LED lights tell us if the elevation DN and UP relays are
functioning properly. When the LED lights, it tells us that the relay has energized and is sending high
voltage (110vac or 220vac) to the elevation motor.
UPSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper display
board to the elevation UP relay. This low voltage dc is what energizes the coil of the relay.
DNSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper display
board to the elevation DOWN relay. This low voltage dc is what energizes the coil of the relay.
BELTSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper
display board to the belt (motor start) relay. This low voltage dc is what energizes the coil of the relay.
SPD (yellow) - The SPD LED flashes on and off (relative to speed) when the speed sensor is
operating properly.
PWM (yellow) - This LED will light when the upper board is sending a speed signal to the PWM.
Both the PWM LED and BELTSW LED must be lit for belt movement.
Finally this this Relay Board, the Each Led will be Lit, for any Relai control for DN down, or UP elevation motor. Use the contact cleaner, you can find it in R .Shack.
see the diagram attached.

Its showing you the voltage out put for the charger if all power lights are lit and the chager is pluged in if batteries show only 2vlts then they are no good and the will not charge up thats why amp meter is on 0

Good Day;
Make sure when measuring voltages that your'e on the proper ground, all TV's this day has two grounds. The HIT has #'s near the components, LED's that light or do not light. YES, get info to trouble shoot further.
Good Luck, big IRISH.

No raster, no sound on 53UWX10B


double check the wire connections, as the filaments not being lit makes me thing a wire isnt connected properly, or one may have been loosend while doing the convergence repairs.

RED light is protect circuit = do not disable !
Look for C702 near flyback transformer - might be hidden in
