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.

SOURCE: how hard it is to replace by yourself main board Samsung LN-T4065

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.

SOURCE: Polaroid 26inch lcd tvred standby light on but power wont turn on

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.

May someone please send the service mode specifications for a Samsung LED 40 inch TV UA40EH5000R?


I don't have service mode specifications but I do have a Samsung and looked around for how to get it in service mode some time ago because the HDMI cables somehow disconnected themselves a lot. Thought it was an electronic problem but it turned out to be a parenting problem instead SO I have never used this information and can not vouch for it. I cut and paste it from a note I copied from a forum entry to use at your discretion:
First post:
To enter "Service Mode" Press the remote - control keys in this sequence :
From Standby Info-Menu-Mute-Power On
- The buttons are active in the service mode.
Remote - Control Key : Power, Arrow Up, Arrow Down, Arrow Left, Arrow Right, Menu, Enter, Number Key(0~9)
Careful though there are things you shouldn't touch in this menu.

Another post:
Method 1
Put TV on standby and then push in series these buttons on the remote: 'info, menu, mute, power' the TV will then turn itself on and display a menu.
Method 2
Turn the power off. On the remote, press Mute followed by 1, 8, 2, Power in sequence.
Method 3
With the TV in standby, press the {DISPLAY} {P.STD} {MUTE} {POWER} on the remote.
Method 4
With the TV in standby, press the {SLEEP} {P.STD} {MUTE} {POWER} on the remote.
Method 5
With the TV in standby, press the {DISPLAY} {MENU} {MUTE} {POWER} on the remote.
Method 6
With the TV in standby. On the remote, press Mute followed by 1, 1, 9, Enter in sequence.

Good luck. Just a basic suggestion you probably don't need: keep track of any changes made by writing them down so you can put it all back if you have to.

My 15 month Celcus LCD423D913FHD tv will not turn on. The standby light is lit and will flicker but will not power up the tv. What is the likely problem?


Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

The remote control will not operate the TV when the TV is in the OFF mode (No LED lit on front bezel). To change the mode from OFF to STANDBY or ON, press the POWER button on the side of the TV. Once the POWER button is pressed, the LED will change to either red to indicate STANDBY or green to indicate ON, whichever mode the TV was in prior to being turned off with the TV POWER button.

By pressing the POWER button on the side of the TV, the mode will toggle from OFF to either STANDBY or ON. If the POWER button is pressed and then the LED on the bezel is red, the TV is in STANDBY mode and will need to be turned on using the remote control. If the POWER button is pressed and then the LED on the bezel is green, the TV is ON.
