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.

Hi Casey,
Replacing the display panel won't fix the tv being stuck in standby mode. More likely replacing and or troubleshooting the power supply and main board might be a better solution.

Is the standby led on the front lit. If not likely the problem is with power supply. If the standby led is on does it go off when the power button is pressed? Does the led blink. If so count the blinks and get back. The power supply provides an standby voltage to the main board. If the standby led is lit then this voltage is present. When the power button is pressed the micro sends a turn on voltage to the power board. Normally the power supply will respond and all other voltages needed to operate the set will come up. if a component is shorted the micro will not turn on the power board and will usually give a failure code via the standby led.

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.

B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Have you set the output voltage correctly?

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 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.
