Re: Transformer

The Power supply was made to fail on this model. I would recommend using a Regular Computer Power Supply. It would cost $20 to $30 dollars for a brand new supply if you don't already have one to use.

Will not turn on.

DVD players are compact complex pieces of circuitry. They're easy enough to manufacturer on an assembly line, but there are so many little components that could break like diodes, chips, or a burned out resistor so unless you have the tools to trouble shoot that level of component there may not be a lot you can do.

Sounds like you have a voltmeter anyway I'm assuming you used to check for power coming into the unit, and you opened it up to check fuses.

Can you see if there is anything coming out of the transformer inside the unit? They don't usually go bad but some component between the transformer and the board could go bad.

As I eluded to above...once you get past the transformer, now you're talking about troubleshooting at the component level which with the tools you have you may not be able to do.

So I would as far the input power which you did, then what's coming out of the transformer. If you see nothing coming out of the transformer then the problem is somewhere between the transformer and input voltage.

If there is something coming out of the transformer probably in the 5V range or lower, then you'll have to trouble shoot components and circuits. At that point you either take it to a repair shop that has the tools (oscilloscopes, circuit testers) to trouble shoot that level of component. OR just go out and buy a new one. The prices on these things has really come down so you may pay more to have the thing repaired.

Good Luck!

No Power?

see the cause and fix it : God bless you
  1. Check if the power cord has been properly connected to the power outlet.
  2. Check if the main power has been switched on.

Power supply blow up and Ihavenot number of i.c next to transformer

Parts are not likely available and it usually is cheaper to buy a new unit but: Google the model to see if a service manual is available (doubtful) or as a last resort call the maker with the model number for assistance.

Sharp dv-rw 260 shut of when playing casette, fuse is ok. No power to start-stop button, cant get casette out, or start player.

Transformer board. Do you have any power after the transformer/transformers?
If so, the board is faulty. If not the transformer is. Either way it's a new board unless you have a good supplier and **** good eyes.

Pioneer DVR-320-S is dead.

Well if it is dead and the transformer is getting power then next step is the processor.  Which if it is dead, then I am sure all the internal components are as well.  My recommendation is have a professional give you and estimate and buy a UPS unit that will regulate the power to you important expensive units such as this.

Dvd player is completely dead.

First thing to check is the power cord with it unpluged. Do you get a resistance there or is it open?? If its no reading at all then the power transformer or fuse or current limiter resistor is open. If you do get a reading then you know your power transformer primary is good. Next measure the AC volts comming from the secondary of the transformer. AC volts? Good! Now Find pin 1 or the end pins on the microprocessor. 5 volts present?? No theres your problem get a schematic and troubleshoot the power supply. Yes 5 volts? Measure the display any volts on it?? Ok im sure by now your gonna say no to one of these and like I said get a schematic and conferm all the voltages are present in the power supply. Most common dead problem in dvd/cd players is the power supply ie transformer,regulator, ic, ect, ect. Good Luck
