SOURCE: BUSTED FUSE

A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs.

SOURCE: Printer won't turn on.

Please follow the instructions given below to troubleshoot the power issue:

1. Connect the printer directly to the power outlet. Surge protectors can actually draw power away from the printer. If this fails, please try multiple power outlets to ensure your specific outlet is not damaged, and make sure the printer is not connected to the PC while testing the unit.
2. When trying to power on the printer, feel the power supply box (if there is one) and note whether or not it is warm. If it is warm, the problem is not in your power supply, but most likely in your printer. If it is cold, the power supply might be defective.
3. Ensure you have the correct power supply connected to the printer.
4. If you have access to a voltmeter, please ensure that the power supply is giving out the correct amount of voltage (most of our printers use 30 volts output).

SOURCE: DVD player won't turn on after power outage

Hiya, sorry to say that the power supply is probably damaged, sometimes happens with power outs. Unless it is expensive model, they are sometimes not worth fixing (although the fault could be very simple like a single diode etc. Maybe send it in and ask for a quote, then decide if it is worth it.

Best of luck

My jvc dvd player xv-thc50 won't turn on


if your dvd player has no any power indicator at the front, the first place to be checked will be the power supply. look for a blown fuse bad component parts like shorted diode and an open resistance.

No power even if I plug my DVD to power source


Good day.

Follow this procedure for trouble shooting.

  1. Remove the cover of your DVD player.Loosening all screw.
  2. Check the input voltage of the power supply 220v/120v AC.If don't have input supply that comes from the ac cord,replace it.
  3. If you have a input voltage supply comes from the power cord.Check the output voltage of the power supply such as 5vdc and 12vdc.
  4. If the you don't have output voltage from the power supply.Check the fuse if busted,check open/change value of capacitor,check power transistor (regulator)if shorted and leak/bulging top capacitor of the power supply board.If you found any defective parts replace it.
  5. If you have output voltage comes from the power supply.The problem could be the main board,replace it.
  6. If you already done this procedure,test it by power ON the DVD player.

I hope this information will be helpful.Thank you and good luck.

I have an SR-DVM700EU that would not power up. I have replaced multiple failed components in the switchmode power supply, and it now works. The unit would power up but stop someway through the booting...


Did you replace ALL the electrolytic capacitors in the power supply? Generally, whenever there are several faulty components in this part of any circuit, it is a good idea to replace all of the caps as well as checking for leaky diodes and faulty IC regulators.

My guess is that the SMPS still has an intermittent partial fault, which is preventing the unit from staying on. I would recommend that you check the ICs in that circuit, replace as required (if you haven't already done so). These can be 3-pin or 5-pin regulators, but they are voltage rated, so obtain the correct types for this model if you do decide to replace them.

I hope the fault hasn't spread to the microprocessor on the main board - this can be expensive to replace if faulty. I would recommend that you re-check the power supply again - thoroughly. Touch up potential dry solder joints if necessary.

If the unit still misbehaves after all of this; perhaps it's time to consider submitting it to a workshop, get a quote (and a second opinion) on the likely cost(s) of repairs, then you can make a decision afterwards as to whether or not you wish to go ahead and get this fixed for good. It's up to you.

MVD2050 will not turn on. We have a DVD stuck in it. We turned the power off and back on after 60 minutes but nothing happens.


Hello K4, hi you can manually get the disk out, but you need to remove the cover. As for the power thing, you have a power supply problem, would you like to service it yourself or call a technician, If you will service it yourself, this are the things you should check:
  1. fuse
  2. open wirings
  3. shorted or over heating rectifier diodes and voltage regulator
  4. bulging filter capacitors
  5. Switching regulator IC, check for the output pulse using a scope.
  6. replace the bad parts, then test.

Our power went out briefly and now the DVD player won't turn on


Hello sir/ma'am, my guess is that the dvd player's power supply fuse gave in. Im not familiar with your dvd player, if you can open the dvd player and locate the check the fuse. replace it if its blown up. hope this helps. if you may have any more inquiry feel free to ask me again. best regards, thanks.

Power surge has killed my DR-MH200SEK


gargame,

good day, if you already replaced the fuse and still keeps on blowing it again. you still have a short circuit somewhere within the power supply area or board.try to check if there are any other blown parts or slightly expanded shape part specially for capacitors near the power supply area .

2) If you do have multi tester and have some basic knowledge with component checking try to check the polyswitch protector, this is connected parralel to AC supply right after the fuse before going to voltage rectifier diode.

3) if it doesn't have a polyswitch protector check the polarity of your rectifier diode, maybe 1 of this 4bridged diode is shorted.

cheers,
mark

Not turning on dvd


maybe you have primary power supply problem! check the fuse! then next check the un regulated power supply if passing... then next check the regulator.
