Bad caps in your high voltage section around the 3 main transformers check them all don't skip one if one reads short pull one end out the circuit board and check it again. Most likely this is your problem

My hotpoint Aquarius wdl540 is dead no lights on or power. Ive have checked the socket the fuse and all the earths everything is fine. Could someone let me know what else it could be. cheers adam


Could be a broken wire. You need to check that power is actually getting to the machine control. I don't know your level of experience, but it means getting inside the electrics which can be dangerous. Safest way is to disconnect from the mains and check the continuity of the 3 plug wires as far along the length as possible. A simple multi-meter is all you need. Follow the cable from the plug to inside the machine, check where the blue wire from the plug is fitted inside the machine and with the meter set on ohms, touch one lead of the meter to that spot and the other lead to the blue wire inside the plug. If you get zero then the wire is not broken. Do the same with both ends of the brown wire and then the earth (green/yellow). Doing it this way isolates you from the live electrics.
If the wires are not broken (i.e. you have continuity) then the problem is with the machine itself and will probably require an engineer. It could be an internal fuse or a complete circuit board failure and anywhere in between.
I hope that is of some help.

My Toshiba TDP-S8 projector will not power up at all.


hi,
check the mains chord, also check the power in the wall socket to which the projector is connected. if all these ok then,may be its power supply side have some problem. its an smps power supply. just check its input fuse on the smps. if it fond faulty the do not replace it suddenly. check is there is any thing faulty on the smps board. because the fuse will blow off only if there is any problem in smps. check it first before inserting fuse.
ok

Which components on hp nc6400 motherboard can cause input power failure


Main component to cause such an issue in the DC socket where you plug the power adapter. This is one of the weakest points in the laptop & usually the first suspect when it comes to input power failure. The socket might either be loose (in which case it will need to be re-soldered), or broken (in which case it will need to be replaced). In either case, you need to disassemble the laptop, pull the motherboard out, & inspect & fix the problem.

The tail light and brake light are out. The fuse is ok. thanks


Of course you put in new light bulbs and a new fuse, just to be sure. If the bike lives outside, things get crusty.
Could be a fuse block problem or the tail light socket and wire.
See if your getting power to the tail light sockets, then unplug it at the wire harness and test the plug in the harness. I've had problems with brake switches and that's another check. The socket assembly is about $15 -$20 bucks. Voltmeters and contact cleaner are cheap at Shucks.

Fault must be in preamp, I got it wrong! TEAC A-H300


Just curious, what preceded this? Sudden spontaneous failure with no manual action associated? Is the Tape Monitor activated?

I don't know how valuable your speakers are but you're hitting them with max power and distortion when you get that bang. I'd use cheap headphones for the troubleshooting phase.

Lighter has no power so I cannot use the garmin. I loked for a fuse marked lighter but there is none. I checked the radio fuse but it's ok.


it probably shares a fuse with somthing else. best thing is to remove each fuse, one ata time and check them all.
If it aint the fuse, have you checked for a live feed at the lighter socket, in the centre at the base. be careful not to short circuit against the side of the socket.
if no live here , try to remove the socket assembly and check for live and earth at the plug. I think the ignition may have to be on for this to operate.

No power when i plug it up !


HI, check to make sure the wall socket is live by, plugging another device into the socket. if the socket is live, this will confirm a internal issue that concerns the power sector of the unit.

Contact pyle for this repair.

***In some model, there will be an In-Line fuse located inside the unit on the power board or transformer. replacing this fuse(if installed), may fix this issue.(uncommon)

Maytag Dishwasher MDBH965AW will not power.


Make sure there's power getting to the dishwasher. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power. Sometimes the power cord disconnects at the dishwasher (inside the junction box, behind the bottom kick panel), if this is the case, the wiring must be repaired or replace

If the junction box checks out ok, the wall outlet socket is live, replace the main control or timer module.

Hotpoint WD64 No power - help please !


hi from n/west uk from the symptoms you describe ? that you have no lights on machine? this is most definately total power loss to machine so if you are certain? the fuse is ok? next is has the wire/lead from plug chaffed or damaged breaking the supply? this next possibility may sound odd but the socket you plug machine into ? may be faulty ie the damp location at rear of machine could have caused deteriation of socket terminals or wires even the wire may have broken/come loose? have had this happen in homes and caused by wires not secured properly and eventually arcing/ resulting in power fail at socket ? may i suggest try another elec appliance ie lamp/hoover/ iron? to check if socket is operating just to eliminate? also if the socket is a fused type? make sure this fuse is ok too? finally have you checked consumer unit for possible seperately fused/trip out for the machine use socket ? hope this helps find fault best wishes
