SOURCE: I have a Hp laptop Pavilion (pav 9000 series) with a blown fuse

Unfortunately I think HP warranty policies state that you can only change by yourself  the components covered by dedicated doors on the chassis bottom, such as the hard disk drive and RAM(obviously your upgrade parts are not covered by hp warranty and not supported by hp support).
So regaldess of how complicated the damage is to fix(most of the led indicators are soldered on the motherboard) you need to call  the HP support and they will fix it, they are usually fast and you will have your laptop back in a week or so...otherwise you will probably lose your warranty if you try to locate and replace the fuse,replace the LEDs, replace the connectors...
it might be a connector plugged backwards but you should not directly try to fix it.

SOURCE: No power

I would guess it's the power unit for the TV itself.

If it's still under guarantee I would have thought you should be able to get it replaced.

SOURCE: Won't power up. Fuse not blown. Q5101 was

Hi,

when you say won't power up, does it mean there is no indication of light whatsoever on the unit? If yes, then it means its having a power problem. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter in order to test the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.
Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

Let me have a feedback if you need more info or help concerning this issue.

Yours sincerely.

Elect_Comp.

My LG Flatron rear projection TV won't turn on. The on/off power button is not turning the TV on. There is no click sound and the red light doesn't come on. The TV is connected to mains power and ther


tried with other ac outlet doesn't work?. if still won't turn on, at this time you will need to remove the rear cover to gain access the internal part. since your tv doesn't have any power indicator, the first place to be checked will be the power supply board this is where the power connector cord is connected. now look for a blown fuse replaced with the same rating. but take note before you replaced the bad fuse you must need to have component testing in the power supply board which the cause of blown of the fuse. like shorted bridge diode, open resistance and defective mosfet or bad regulator ic.at this time you will need a device called digital tester to check weather the parts need replacement.hope this can help good luck.

I have the Sony S2 Sports ZS X1 and it will not turn on.


Before confirm transformer fault, load batteries and see whether it works. After loading batteries, pull out its AC cord from its AC socket at it back side. With AC cord connected at the back of the set, battery supply won't connected to the set. There is a cut - off switch at the AC socket. Only after removing the AC cord, the set will work on battery.
Try this. If it works with battery, make sure that transformer or internal mains fuse has blown out.

Tv won't turn on


Hello
Chech whether AC power get into the power supply regulator section. Just open your tV, and check it. There is a fuse [ glass cartridge type] on the power supply section. Check whether it has blown up or not. If blown up, make sure that there is some shorted components at the power supply section check it.

No power on my JVC Kaboom


I would rule out the power supply simply because the batteries won't run it either. The internal plug that takes the cord should be checked for cracked solder joints, because the plug goes to battery mode when cord is removed and AC fuction when cord is plugged in. It is possible it may be an audio output problem given the age of the item.

Some cars have a thermostat that tells the fans when the water temp reaches a certain temp then the fans start. Or the relay that starts them could be bad. You may find the relay and switch it with another like it and see if that works.

Have an Samsung SM2443BW, probably damaged by surge from lightnihg, nothing obvious but won't turn on at all. Advice to find a fuse, advice about likely damage much appreciated


There is a main AC fuse in the power supply board, it can be soldered in place or clipped on. Look at the where the power cord is attached to then you can trace that to the power supply board, the fuse should be labeled with something like F1.
It MOV's (surge protection devices) in the power supply board may have blown also.
Please read my guides to get more understanding.

My Bernina Activa 240 won't turn on. I checked the outlets and they are fine. I even plugged it into different outlets hoping for something to work and it didn't. Can I take it apart and fix it...


Likely the problem is a blown fuse in the S-Print (power supply). You must have a grounding wrist strap when working with a Bernina Activa. They are extremely sensitive and can easily destroy the main circuit board if you don't use a wrist strap. You can get one at Radio Shack for less than $5. The power supply is the square 1/3 of the machine on the back on the handwheel side. You can remove the power supply by removing the long torx screw on the rear of the machine and tilting out enough to unplug the connector. Then dismantle the power supply until you can get to the fuse. Test the fuse with a continuity tester. If the fuse is blown, buy an exact fuse. Don not deviate. If the fuse is not blown, you may need a new power supply.
