Sony KDL-40S20L1 Flashing Standby Led, No pic, No Sound

My KDL-40S20l1 standby led flashe red 4 times pauses and the flashes red 4 times and keeps doing this. There is no sound and no picture. The power button does nothing. I tried the up arrow on the remote while pushing the power button on the set, this did nothing. I tried pushing display > 5 > + > power on the remote with no results. The manual says 4 flashes on the power led is a backlight failure. The power led is not lit at all, only the standby led flashes.

    Thanks, but that's the owners manual and doesn't really tell me anything.

    I guess what I need to ask is, what does the sequence of four on the standby led mean? The service manual says the power led is the one that you count the flashes on. The power led does not light at all.

Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

    Hi again,

    4 blinks of the standby led - Most probably video muting caused by (in some models/version/firmware):
    1. vertical stop
    2. absence of source
    3. video board fault

    Pls note:
    a. Most probably & in some models/version/firmware - Sony uses same model number but for different regions and/or different versions of the firmware and therefore the blinks may refer to something else;
    b. When you press the buttons: Display, Channel, 5, volume Minus,(not plus )then Power, this normally should bring up a screen with a list of the problems and number of times they have occurred.

    The blinks indicate error codes but not necessarily the exact board/component at fault. At most that it can tell you is where to start diagnosis.

    Most techs (or even Sony Service for that matter) would suggest that you try a hard reset as most cases are resolved this way.

    Hope this be of further assistance to you.

Hi I ve a sony KDL-40W2000 stuck on stdby red light flashing 4 times the stop for 3 second ??any advice please


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

The red standby light flashes in the code of 4 times then pauses then 4 times then pauses


Five times blinks to Sony Bravia is related with an IRK error. It is related to its main digital board. In most cases, the main board might need replacement. It will be best to contact the authorized service center for Sony. If you're sound in electronics, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by type in the model name to your set in its search box, or view it in Mosaic /Timeslide option.

Over voltage protection function is turned ON. Just unplug the TV from AC mains wall socket, and re-plug it back after 10 minutes or so and check. If it do not help you, the main power regulator board should be checked and replaced.

Sony Bravia KDL-40V300 won't turn on.


Unfortunately 5 blinks is a LCD panel error. The only way to fix it is to replace the whole LCD panel. This is the most expensive part in the TV.
part number: 1-802-488-12
List price: $1336.32
Core charge: 1790.00
You could try to replace it yourself but would need to take the whole TV apart by first taking off the back cover, then removing all the boards in order to get to the panel before putting it back together but I would just recommend buying a new TV as the price of the repair exceeds the price of a new TV of the same size.

Sony Bravia KDL 46", no picture, standby light blinks 4 times


Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

Four blinking red lights.


Either on of the backlight inverter boards is bad or a backlight has failed inside the panel.

The red light should be blinking a code. For example it will blink 4 times pause then 4 times pause or 5times pause 5 times pause, whatever the error might be. Let me know what it is and then we can help more.
