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

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.

SOURCE: 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.

SOURCE: tv shuts off spontaneously. red power light blinks.

re: sony flat panel lcd tv mod. # klv s 40a10.
No power. When power button is pressed, nothing happens.
The stand-by at the power supply ( cn6201) measures to be 3.47 v. instead of 5 v. However, when I unplug cn6201 (5 pin connector) I can read 5v. at the power supply.
Any suggestions?

Kdl-55ex620 red light blinks 3 times


Hi,
Unplug your TV from the AC power. Press and hold the power button on the TV itself for about 10 seconds and then release. After another minute, plug the TV back in and press power once.
If the blinking is still occurring then this unfortunately indicates a failure within the TV and will require a service. If all OK then happy viewing!

Sony flat screen tv-model KDL 40S4100


sounds like its more to do with the memory, there is system memory this is the one with the log, this memory only covers basic stuff ie turn on parts and log, then there is working memory that controls your settings and the pre installed setting, it could be that the settings have gotten mixed up, and it might just need a full reset in menu you should find return to factory settings, it should revert back to new and be ok after this has been set. hue sounds like its setting its self and reset should stop[ this on reboot.

Sony KDL-V32XBR1 Displays only snowy picture


Here are a few more troubleshooting steps you can try when your TV picture is just snow. I see that you have already rebooted your TV, but did you turn your set-top box off and on, too?

1. Does the picture show when you play a DVD?
2. Check all of the connections between the TV, outlet and set-top box and make sure everything is secured.
3. Is your TV set to the correct channel (typically 3, but in some areas 2 or 4)?
4. Press any key on the remote to see if the correct mode lights up. (Ex: if you have cable, the cable button should light up). If it doesn't, press the correct mode's button to regain control and change channels.
5. Call your service provider and make sure it's not an overall service outage.
6. Do you have sound but no picture? If so, it could mean a backlight failure.

For more suggestions, see TV black screen or snowy screen for troubleshooting and solutions. I hope this helps!

Poor picture quality


Hello Paul. I have this same monitor, but rebranded, Access the service menu with the remote control:

With user’s RC
1. Power TV On
2. Press Menu button and call up User OSD Menu
3. Select Sound-> Balance
4. When Balance value is “0”,Enter 0->5->3 ->2 in sequence.
Note: If necessary, re-do number keys.
5. Factory OSD appears.
6. Press the standby button then AC turn off and restart the TV, which can exit factory
OSD menu.


Now you will be able to change the values for Red Green and Blue channels. I also hated this TV, but after adjusting the colors it's looking great! Hope you could fix it too! :)
