Why my dvd player by Philips model number pet702p/37 want charge when I plug it in the red light comes on and goes out after a few minutes but it won't charge what do I need to do

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

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 plug the DVD player in and then the screen flickers then nothing

I have found that sometimes the wiring harness comes loose from the main board. The player must be dis-assembled in order to access the main board and display board, you may find the plugs have not been properly seated from manufacture and just need to be inserted to hopefully get your system working.

I plug in my DVD player and I get nothing, not even the power light comes on....

You have a power supply problem, if the cord is detachable from the player make sure it is snug tight, next pull the cover off and follow the cord to the power supply board to see if the fuse is blown, the other thing I come across is a bad capacitor near power transistor but this will require some technical know how. One final thought, check your unit on another wall receptacle.

I can not get my recorder to work when I plug it in it dose not come on. I lost power a couple of times when I was at work now it will not come on. where can I get it fixed

Check the in line fuse...If you remove the unit cover the inline fuse sits right behind the plug socket...If the fuse is okay, then you will need to replace these two capacitors on the same power circuit board...One is at location C19, 3300uf, 10 volt, and c23, 1000uf, 10volt...

I will not come on

Try changing the fuse in the plug , try operating the power button on the DVd recorder, if that doesnt work then there is a faulty component inside the DVD recorder on the power supply board which could either be a fuse or a damaged component.

I plug it in to mains and all that happens is a white light comes on on front panel it also flickers every now and again?

You almost certainly have problems with the power supply board which fails fairly often in these machines. They are available for around 80 euros, trouble is that having bought one it is not uncommon to plug it in only to find you have another problem. Your best bet is to take it to a big JVC service centre where they will have the spares to try substitute components without you having to buy them first!

Dvd player, pvd-709

Hi lindy,
My kid broke the ribbon tape, so I took it apart. It is easy to fix all you have to do is plug it back in if the connectors are in tact. 1 goes to the reader and the other plugs into the circuit board. My problem is that I cant find a new flat ribbon cable/wire anywhere.

Audiovox battery charger Rbn-300

If you remove the 4 screws to the top of the RBN-300 battery holder, then separate the halves, you will see a small IC board charge controller in the top 1/2. Remove the 3 screws to it, gently remove the board & (with a magnifier) look at the contact to the side of the board from the power plug (close to the LED light.
If you wiggle the low volt power plug, I expect you will see that the solder joint has broken on the board edge. Resolder & reassemble -I use hot melt glue to help support the plug to avoid re-breakage between plug & board.
This may fix your problem unless the erratic circuit connection has killed either the control board or you battery.

if it isnt more than 1 year old wal mart will exchange it. if they wont the connection in the unit might have come loose from the board if so you can have it soldered back onto the board. or you might have to replace the the plug in in the unit.
