Standby DVD is in standby.When standby is releasing,the supply voltages are fed to the MPEG board.but there is no display and no action.

Power supply board is the first one to check, then the main board. The power supply board has to have all the voltages present. The main board controls the power-up signal on power supply board.

Stand by is on the power board but it is possible for standby to be up and running and main supply not working. Did you look for bad caps on power board or any voltages coming out of that board?

When the STANDBY indicator

flashes

Immediately unplug the power cord

and check the following items.

• If your unit have a voltage selector,

is the voltage selector set to the

correct voltage?

Check the voltage for your region,

then make sure the voltage selector

is set correctly.

• Are the + and - speaker cords shortcircuited?

• Are you using the supplied

speakers?

• Is anything blocking the ventilation

holes on the rear of the unit?

After checking the above items and

fixing any problems, plug in the power

cord again and turn on the unit. If the

STANDBY indicator still flashes, or if

the cause of the problem cannot be

found even after checking all the

above items, consult your dealer.

module defective need to re-hest or replace the module board,or weak voltage from other power supply.

The problem is in the power supply board, often caused by a defective capacitor that becomes open, cap value is usually around 1000uf and sometimes shows a bulge at top leaking contents, if you are handy with a soldering iron replace part with identical value and voltage rating and observe the polarity.

the possible problem of it is a defective mpeg board or the belt in tray to make it open if the motor have a supply to turn the motor the problem is the belt but if it has no supply from the mpeg to the motor the defect is on the mpeg board

Hi,
Below is view of voltage out put connectors of power supply of AVD-S50ES
You can confirm volts on connectors as mentioned here.


Good Luck.

Hi,

If there are no indicators that it is receiving power such as timer/clock, standby light, whirring sound when first plugged in, then initially, it would be safe to say that the internal power supply is the culprit. For the moment, course of action would be:

• confirm power availability on the outlet (which as you posted performed already);
• check the AC cord/powerline of the unit with a continuity tester;
• check the fuse (inside);
• check for the presence of standby voltage (normally +5).

Of course most of the above would require opening the unit which needs a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Hi kamil. Mo medenom, nomogom! I think problem isn't in power supply. It should be in control board (madaar-e farmaan). Hossain Shahidzadeh

turn the power on. to get rid of the red light you need to press the timer/rec button on the remote until it turns off. the red light means it is programed to record.
