No fuse holder under voltage selector switch in my grundig satellite 3000 reciver.

On the rear where the power adapter plugs in, it should show in input voltage and polarity. Check the power supply output voltage with a volt meter. Generally, it is the sum total of all the batteries, so it if takes 4xAA @1.5 volt batteries the voltage would be 6 volts DC. It sounds like it is faulty.

In North America, the voltage is nominally 110v. In London, 230. You may only have blown a fuse or the AC adapter, but you could have fried the whole unit.

This could be as simple as a connector working loose. You need to open the radio by removing the 4 screws in the back of the case (2 are under the handle, and one is in the battery compartment). These screws are identified by a small arrow pointing at the screw hole. Once the screws are out, gently pry the bottom out first (the top has the catches in it), then pull down slightly and remove the back side of the case. there will be one wire on a connector going to the battery compartment you will have to disconnect before the back of the case is entirely free.

After the case is open you will have access to the connectors on the RF board. Make sure all 4 connectors are fully seated. There is another connector under the RF board going to the processor/display board you will need to check if the other 4 connectors are OK. You need to remove the 5 screws holding the main board in place so you can remove it to check the last connector.

You do not need to reassemble the radio to check to see if this has worked. You can plug the AC adapter in and test by pressing the power button.

If this does not work, there is a fuse you can check. These rarely fail, but it is possible. The fuse is located near the external power receptacle, and is mounted on the component side of the audio/potentiometer board. This is the circuit board with the volume, bass, and treble controls on it. You will be looking at the solder side of this board, but by tilting the radio up (with the back cover off) you cann see enough under the board to see the fuse. You can pop it out of its holder and check with an ohm meter.

Dear Sir:

Thank you by your request, I will help you right now.

Please do this step with VERY CAREFULLY!!!.

A multimeter isa versatile tool for measuring voltage and current. Electricians usemultimeters to measure alternating current, or AC, and direct current, or DC,voltages and currents. Many multimeters also measure resistance, capacitanceand temperature. For example, an electrician uses the multimeter's AC voltagesetting to determine if a wall outlet has power or if a power supply isfunctioning. This knowledge helps the electrician pinpoint the cause of anelectrical problem and select the appropriate repair. Difficulty: Moderately EasyInstructions

• 1

Plugthe black voltage probe into the voltmeter jack marked "COM."

• 2

Plugthe red voltage probe into the voltmeter jack marked "V."

• 3

Rotatethe range selector knob to the highest range setting, which is marked"VAC."

• 4

Turnthe voltmeter on. Slide the power switch to the "ON" position.

• 5

Touchthe probes to the device for which you measure the AC voltage. Use extremecaution. Ensure that the probes do not come into contact with anything but thesurface you are measuring.

• 6

Readthe voltmeter's display. Turn the range selector knob to a lower range ifvoltage is less than the currently selected range
Thank you in advance, sincerely. God bless you.

It's lowest operating frequency should be 100 kHz, unless it has been altered. What you would hear below 100 kHz is a mystery.

I just repaired a PMP3000.

A bit of warning on these. Do not let a speaker leads get pulled while powered. They can arc out the power amp causing extensive damage.

If the fuse ever blows do NOT replace the fuse as much more damage will result. Service the unit before using.

have you fixed it already?
I have the same receiver with the same problem as yours.
I found the fault in the voltage selector rotary switch. I'm refering to the round voltage selector switch not the other one, because you'll notice that there are 2 voltage selector switches at the back. The lock was broken so it couldn't switch the primary terminals of the main transformer.
Basically this amp has 2 power transformer, the small standby traffo and the large main traffo.
Try to press that round switch and press the front panel power switch. If it goes ON, then fix the center lock of that round switch.
Hope it helps.
:-)

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If the TV is less than one year from the date of purchase, it is still under warranty. Call the number above so that you can have the unit repaired.

Please post a comment if you need additional assistance so that I can help you further.

the relays will either be under the hood driver side or in the truck under the dash with the fuse box. The fuse box is either on the lower part of the dash or under the dash near the floor board toward the firewall

Low voltage Tx actually OK. Restored vaporised circuit tracks on controller board, fuse and interior light globe. All working OK.
