1.5 amp fuse on main powerboard blown

The problem with this unit seems to be that the voltage over the main fuse is pulsating as the green led on front of unit is flashing in the same way.It got me thinking that maybe the oscillator is not kicking the unit out of standby,but with no curcuit diagram and having great trouble in obtaining one,not that i have'nt tryed,your help would be most appreciated.Many thanks Mr.S.Hatcher.

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

SOURCE: LG LCD TV Standby Light Flashing Red Continuously

I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.

SOURCE: LED Indicator Problems & Flasher Relay?

Modern Ducatis (and cars) don't have a conventional flasher. The blink rate is controlled by the dash cpu. The blink rate change is used to indicate that a bulb is out (by sensing low resistance). Using a resistor will fool the cpu into blinking correctly.

I dont seem to have a power supply to my Waeco air con roof unit


Check breaker at main panel. Check breaker if applicable in disconne t on roof. If this is a pull out disconnect make sure it is installed the right side up. If no issues with high voltage you may have a blown fuse on the low voltage side. Turn power off at disconnect, open machine and look for a small,blade style, like one for a car, 5 amp fuse that may possibly be blown.

My ford kuga has no electrics and will not start nor does the central locking system work !! Have you any idea why?


First check the battery voltage with a multi meter the voltage should be around 12.53 v if it is lower then 12v the cars Bsi unit wont wake as the Canbus electronic system is power hungry.

If the Battery voltage is correct then check the main fuses under the engine compartment and then check the interior fuses for a possible blown fuse. As the main system function are not working then the cause will most certainly be a blown higher amp fuse 30 amp / 60 amp which protects the starting and charging circuits.

Have no spark. Changed coil & CDI box so far. still no spark. Is it the internal coil? 1989 enticer 400T/R


Hi and welcome to FixYa,
Initially, suggested checks on the wires:
  • black of igniter unit tied to ground;
  • orange wire from igniter to ignition coil with pulsating voltage when starting;
  • gray wire from igniter to ignition coil with pulsating voltage when starting;
  • IGN + 12 on red/white wire to igniter and ignition coils from engine stop switch;
  • IGN + 12 on red/white wire to engine stop switch coming from 10Amp ignition fuse;
  • pulsating low voltage from pickup coil between the wires black/white, white/green & yellow/red.
Postback results of above voltage tests.
Good luck and thank you for asking FixYa. Happy Holidays.

Amp Stopped working.


I would suggest checking the unit for cold solder joints or bad solder joints. The onlt hope after that is a bad component. You will need a schematic and multimeter to do this with. Open the unit and measuer the main rail voltage this will provide the data you need to troubleshoot the unit with the use of the schematic.

No Power


Hello jasper100, Have you opened the unit to take a look inside? Since you dont have a blown fuse we cans assue the a short has not occured. Now I would chect to see if the voltage regulator in the amp has voltage coming from it. It may not in that case you may have to remover the old regulator and put in a new one just to get to the point of properly troubleshooting this amp. I would suggest that you get a schematic for this unit and use a multimeter to look at the voltages in the power supply section and see which sections have no rail voltage (12v supply voltage). I would also advise checking the remote to for regulator failure.

Pulsating power LED. No picture. No sound


Either the main smoothing capacitor or the voltage regulator are faulty. You may find that the power LED will stay on after pulsating for several minutes, at which time you can switch the TV on.
