Question about Televison & Video

Open Question

Good afternoon. I have a ln32a450c1dxza model LCD television. My problem is that the tv stays in a standby mode.

So far, I've changed the power control board, main board and the ir board. At this point I'm at a loss.

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

You need to open it up and checking the voltages in the power supply sections, you should have 5v (for logic circuits), 12v for sound, 24v for backlight inverter circuits. Look for bad caps with bulging tops in power supply also.

usually capacitors are the problem on the TDA03211c power supply. 450v (volts) @ 10uf. change both. beside inverter filters.

How do i get my tv to power up after replacing the power supply


The signal that controls on and off comes from the IR (Remote) board through the main circuit board then to the power supply board.
If it does not turn on with the button on the TV there could be a fault on the main circuit board. Make sure all the cables are fully in place on their connection points.

Tip

Tips on how to repair a Remote controller.


Before you throw away your old remote have a try with these tips: First of all remove the panel by using a sharp knife on the sides, come have screws inside the battery chamber.Once remvoed you can find the main board on which is the circuit and the carbon pads. Solder the IC the crystal, the IR LED, the driver out transistor.
make sure the battery voltage goes to the IC and there is no track loss/break.If battery had leaked into make sure to clean well with petrol and insulate after soldering with varnish.
With the battery connected check the voltage on the IC, press a pad and check for the output at IR led.
Now use a IR detector with a multimeter( in Ohms range) to see the voltage change when the remote is pressed.
Now try this on or change the crystal or IC, to get your remote working again.

At power up, tv scrolls uncontrolably through channels, power light flickers


1. Take remote control far away from tv - 3rd or fourth room. Then switch on tv. If uncontrollable scrolling stops , then cause may be remote button (Ch+ or Ch-) has got dirt inside and its shorting.

2. If taking remote far away doesn't stop scrolling then (Ch+ or Ch-) button on front pannel has shorted. Take a cutter plier and care fully remove button from its circuit board. ( If you know desoldering, it is far better than cutting). If scrolling stops then you can operate channel change with remote.

Power button does not work on remote


REMOTE:

Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

Hi I recently change the main board of my protron 32"pltv television and my remote control does not work anymore, do I need to change the IR remote receiver


You will need the scope to find out if the IR receiver is putting out the signal to the main board, or take a chance by replacing the IR board. Did the remote work before changing the main board?

Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera’s Lens (Digital Camera can detect IR), you should see flashing light on the camera’s screen when any one of the remote button is pushed.

Relay click and 9 blinking led.


Try the following steps:
1. Remove the power supply to X Main board, check VE. If you get normal VE then replace the X Main board. Otherwise to 2.
2. Remove the power supply to Y Main board, check VE. If you get VE then replace the Y Main board, otherwise to 3.
3. Replace the SMPS board & SMPS 200V board.

Good Luck
