SOURCE: amp blows fuses

The fuses are there to protect the internals of the AMP.....
Please check that the correct fuses are installed......
if the incorrect ones are installed then a fire may develope...

There should be a manufacturers lable on the external chassis that details the fuses to use....

Fuses now days can be slow blow or fast blow....so the correct fuses must be used.....dont increase the fuse rating past the chassis panel label...but make sure they are correct...if they are correct then the amp needs a service to determine where the peak loadings to the power supply are originating from...

Some one may have installed incorrect fuses in the past...

Cheers from YUBEUT

Check D1SS16, a diode in secondary supply near the transformer. It's probably short circuit. Replace it with an SF-26, 400V, 2A rectifier diode, or equivalent.

SOURCE: Protection displayed and shuts off

The protect message indicates that the output amp section has a problem. Normally this requires the replacement of the output transistors or the output amp pac. Expect the repair cost to be about $20-$60 for parts plus the local labor rate.

SOURCE: brocken freelander sunroof

The motor is accessed after removing the interior roof light console. I have to warn you that Freelander sunroofs have a lot of problems. To change the motor, I think you will have to remove the roof lining as well with all that entails. The Land Rover Workshop manual has all the detail whereas the Haynes manual does not.
Try www.myfreelander.co.uk/Body/sunroof5door.htm for an exploded view of the sunroof.

Incoming Power Problem If the washer won't start check to see if there is power at the electrical outlet which the washer is plugged into. Plug a lamp or radio into the outlet to check it. If the outlet is dead, check the circuit breakers or fuses for the home.

Power Cord If the washer won't start, check to be sure there is power to the electrical outlet for the home. If that is OK, the power cord itself might be defective. This is rare. You can check the power cord with an Ohm meter for continuity.
User Control and Display Board If the washer won't start, the user control and display board may be defective. Check for power to the washer first.



Timer If the washer won't start the timer might be defective. This part is often misdiagnosed, check other components before replacing this timer.



Line Fuse If the washer won't start the line fuse might have blown.



Thermal Fuse If the washer won't start the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.



Line Fuse and Holder If the washer won't start the line fuse might have blown, or the line fuse holder might be damaged and need to be replaced.

Main Control Board If the washer won't start the main control board might be defective. This is not common. Check other parts and causes first.



Door or Lid Latch Assembly If the washer won't start the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.



Door Lock Motor and Switch Assembly If the washer won't start the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design.

Vcr not working


Hello!
Sorry to admit, but your VCR's signal processor is down. On screen display is generated by microprocessor, but video signal by different circuitry. Anyway, there is nothing you can do, except surrender to repair shop. Or, worst case scenario: buy another one. Even though I won't recommend to do so. "Modern" VCRs are cheap plastic toys, won't last too long, no replacement parts available, etc. If you have some technician's background, you may open the unit and look for "bloated" capacitors in power supply area or check electrolytic capacitors with "in circuit" capacitor checked, if you have one. If not: try to look for reputable repair shop, what stays in business for a while. there, still might be the people, familiar with VCR problems.
good luck with your project,
thanks,
Alex.

On my Panasonic model th42px75u. no power. When I press the power button, I hear a clicking sound in the power supply area. Checked both fuses. They're good.Thoughts?


Re you getting the standby red light when you switch on the power??????? If not, then I will advise you to check with another power cord which will confirm you that old power cable is defective. If so, check all the connections i.e. power plug, wall socket and the TV end. If all these are OK then the trouble lies with your switch. It is not making contact though it may be giving clicking sound. Have it changed since you have already checked the fuses.

Panasonic PV-4664 VR wont't power on. Replaced 1.6A input fuse and fuse blows immendiately when power supply is both installed and removed from the unit. Appears the power supply has a problem.


Fuses blow like that when a semi-conductor has shorted and acting like a piece of wire. Transistors diodes etc will show up quick with a Ohm meter, has it will be just like you have touched the probes together!

Tv wont switch on


This could be a problem with the power supply. Yes there is a fuse on the power supply & if you have a multi-meter & are competent with electrical safety, you could test it. However, if it has blown then almost certainly something else will have caused it. You might have a short circuit bridge rectifier or faulty chopper transistor. If the fuse is ok, then you will need to check voltages from the power supply to find out what feeds you have. There may be a start resistor open circuit for example. If most of the start up voltages are ok, then you need to look at the line output stage & check if this circuit is getting any voltage supply.

If the MFD (Multi Function Flourescent Display is not working, check the -27 - 30 Volt (minus 27V to minus 30V) supply line. The fuse or a fuse resistor (around .5ohms 1/8W ) will be blown.

Also, it is possible that the 3V AC heater supply line is disconnected at some point.
Check that also.
