The amp itself has a fuse. Thats the first thing I would check, if not it could be a bad or loose ground.
Good Luck!

What fuse controls the blower motor and cigar lighter

You people need to list the year, make, model, & engine size, when asking a question. It helps when we know which vehicle it is.
All I can tell you right now, is take of the cover to the fuse box, it should be marked on the inside of the cover. If not & your blower motor & cigarette light are both not working & you suspect a fuse,
you will need a test light, clip it to a good ground, then with the key on (motor off) touch the little metal taps that are on each side of where it states the size of the fuse, the test light should light, when you touch each tab, if it only lights on one side, then that means that side is the hit side & the fuse is blown preventing the current from traveling to the other side to feed the power to whatever circuit your testing. One you find the blown fuse, you can pull it & see it's blown

Marantz PM-66 SE: Power light comes on, but the amp does not work

try taking a flashlight and look through cover into unit for a blown fuse or take cover off (which is better) if taking cover off unplug unit. If a fuse is blown remove it and take to a store like Radio Shack for proper fuse watt and amp..if fuses are ok i would get it fixed...sounds like a minor problem since main power is there. GL

Make sure the remote turn on cable is connected correctly and fuses on the amp are not loose. But first off jump power from the power terminal to the remote terminal to see if it even turns on. if it does not then the problem is something blown inside the amp. Is there a fuse under the hood? if so make sure it is not blown.

All amps comes with fuses near to the power supply, the yamaha's fuses will be inside the amp. check the fuses if the fuses are not blown than the power supply must be tested by a technician.

My 2000 watts legecy amp is not working whats wrong with it?

HelloPower light doesn't come ON, means there is no power enters inside the circuits. There will be an over current protection fuse, inside the amp, meant to blow up, if any short circuit occur inside the circuit board of the amp, or at outside speaker connection. You should locate this fuse and check it. it will be a glass cartridge type, slided into a fuse holder. You can detach it from its holder by a hard pull out. Just locate it, detach it from the fuse holder, and check it with a multimeter, set in Ohms range. The meter should show continuity. If there is no continuity, means the fuse is blown up. Before replacing the fuse, you have to check the reason for its failure. Without rectifying the reason, if you insert an other fuse and switch ON the set, the inserted new fuse also will blow up. Sometimes, it may cause to further component damage too.So check the circuit for any short. You must have thorough knowledge in electronics and all tools to do the work. If you are not aware in electronics, get this set repaired by any experienced service technician. OK.

Well my 5500 amp has evidently stoppe functioning.

What I would do is look around inside and see if anything is burnt or broken, pay close attention to the heat sink area.
With neither channel working you have something that's common to both channels that is causing the trouble.
You should be able to see any fuse by looking inside, they might be covered up, but should be easy to get to.

I blew the main fuse in my engine compartment, i had it replaced but still have no power to my radio and no interior dome lights. Already checked fuses?

apparently there is a 125 amp fuse between the + and - on the battery/ fuse area (engine side). Get this changed, and everything should come back.

Toshiba 57H81 Flashing Red Power Light, Blown Fused F850+F852

Solved by resoldering some solder joints!!!!!!!
Toshiba Model 57H81 Rear Projection TV - Purchased 11-09-2001

Problem: Toshiba 57H81 Flashing Red Power Light, No Picture/Sound, Blown Fuses F850 + F852

Symptoms January, 2009:

  • Upon turning on set I got flashing red power light and nothing else.
  • Removing plug for one minute and plugging in results in:
    • Audible click, steady red power light for 2 seconds then slow flashing red light
    • Pushing power button results in steady red for about 2 seconds then slow flashing red light, no other set activity
  • Removing power cord for several hours and plugging back in made no change
    • Audible click, steady red for about 2 seconds then slow flashing red light
  • Possible related note: Over past several months occasionally the entire screen would flicker momentarily and at other times be problem free for weeks.
  • Fuses F850 and F852 found blown

Repairs Made:
  • PD0074 DEF/CON Power Board
    • There are two main power supply capacitors in this set. They are C-809 and C-810. One their negative lead on the printed circuit board re-soldered leads and nearby contacts. I’m told that because the factory left out a printed circuit board eyelet, the connection will come loose over time. When I called Toshiba customer service they said there was a known solder joint problem causing blinking red light.
    • Replaced blown fuses F850 and F852.
      • I actually installed a fuse panel on the inside of the cabinet and routed the fuse connections here instead of ordering the special fuses and replacing them on the circuit board.
      • Had to use a 5 Amp SLO-BLOW for F850. Fast blow does not survive power up. Get the red blinking light.
      • Used a fast blow 2 Amp for F852.
  • PD0073 SIGNAL Board
    • Re-soldered Q751 + Q752 STK392-110 Convergence Amps
    • Re-soldered adjacent pads that looks suspicious

Total Cost to Repair about $10
  • Twelve hours of my time over three days to research issue, disassemble set, make repairs, add fuse panel.
  • Already owned Service Manual and Circuit diagrams from a different 2004 repair.
  • Less than ten dollars at Radio Shack for fuses and fuse panel. Already had wires, etc.
  • Some solder. Already owned de-soldering tools, etc.
  • Visited both local authorized Toshiba factory service repair facilities. One said repair would have to include replacing Q751 + Q752 STK392-110 Convergence Amps with ST392-180, and realigning set for a total of $500+ and it would be more if they had to order a power board. NO THANK YOU! Other shop said $65 for site visit and $30 to make an estimate that could be applied to repair.

When powered on protection light comes on

Protection usually means that there is a short some where. If it is inside the amp or external I couldn't tell you. You could check the fuse to make sure that isn't blown. I had a Memphis amp that blew both fuses and the protection light came on. I swapped out the fuses and worked fine, still works. If you have a multimeter set it to OHMs and check the resistance between the power terminals. It should be very high. If these things don't work then there is most likely something wrong with the amp or your power termination. I wasn't able to find a lot of information on this amp but if it has screw type terminals, did you use terminals. If you just put the wires in the terminals make sure there wasn't loose strands touching. I hope you can get this one.
