It doesn't work

I have this dvd player.

it doesn't go on. i checked the power supply, and the transformer outputs less voltage as necessary.for example on the 5.5V pin just get 3V.

does someone know where the problem can be, usually?

I think you solved your own problem. If your not getting enough power then one of the symptoms of not having enough power is not powering on, weird behavior, or a weak power light.

My Toshiba RDXV60 stopped working, there are no lights no sound and will not respond to the remote or to button operation.


if you want to confirm if the transformer in the power supply is also bad you have to make a voltage checking. turn on the dvd player and make a voltage checking at the output at the power supply board.

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.

No power dvd player


if your DVD player have no power first step is find where is power supply section then check your output voltage buy using your multiple tester and range it to dc then check if have a supply 5volts and 12volts if no output you can check some diode to your power supply or you can buy a 1 set of new power supply its available to the market thank you

Cyber Home dvd player model CH-DVD 320 displays loading and never plays movie


Check the 5V power supply output. If its less than 4V it will cause this problem. Replace 5V power supply filter capacitors.

My player keeps giving me a bad disc error no matter what DVD


Realign the laser. I'd take it to a shop & let a technician do it

No power


Is the fuse located before or after the main power switch?

If the answer is before the main switch, then maybe you should also check the main power switch (dirty contacts - these may cause insufficent voltages from the power supply).

Note that the (electrolytic) capacitors can be faulty but will not have visible damage, so check the DC voltages on the power supply output and try to replace the associated capacitors if the voltages seem to be too low (usually, there will be 12 and 5 volts outputs, sometimes a 3 volt output on some brands/models).

If it turns out that these voltages are not present at all, then there may be damage to the transformer driver IC (i'm assuming this is a switching power suply) - see if there is any AC voltage present at the secondary terminals of the transformer, if there is none, then the primary is most likely not being driven by the 110 V and this points to the driver IC as the possible cause. It may also be some other component in the primary section, but you said you've checked them out, so i don't know what else to suggest.

Hope you can fix it.

Sounds like you have a capacitor problem.You need to open the dvd player up and check all the capacitors located on the power board.Make sure it is unplugged and be careful.There will still be some charge inside the unit.

My dvd player is dead.


You check the SMPS (Power Supply Section) and verify the voltages from the various terminals of the transformer accordingly check the bridge, voltage regulator, and filter circuits. If any of this parts are gone replace the appropriate parts not the all.
