Hello antlisa02:
First lets try a hard reset, that means unplug your tv from the outlet thats providing power to your set. Leave it unplugged for at least a couple of minutes. Plug it back in and hopefully your TV has reset itself.
Other than that you might have to have it professionally looked at.
Here is a link for your manual, maybe it might help you.

First disconnect all power to the TV for about 30 minutes this gives the filter caps time to discharge as this resets the logic section upon power-up. After 30 min try powering back up if you still have the same problem then there's a problem with the power supply board. You may have some caps with high ESR levels which can cause this kind of fault. But it could other components on the power board causing a similar fault like switching transformers that have shorted, or opened either which can cause EDDY Currents which will cause feedback in opto-couplers and shut the TV down. Let me know what results you get after the 30 minute power-down.

Samsung 55" flat panel lcd tv is not coming on the standby button light stayes on but no picture coming on it doesn't come on with the switch only by plugin it to the outlet.


Does the backlight come on? or even flash on and off when the TV is switched on? I presume the standby light is showing 'blue' then. Do you have any sound? Also, when the TV remote is pressed, does the standby light flicker?

Subject

Unable to Power On or Off the set

Symptoms / Customer Description
The symptom may occur while the TV is ON or in Standby.

1) If the problem occurs while the TV is in Standby:
The TV will not turn on via the remote or power button located on the set however after AC reset (i.e. unplug the TV for at least 30 seconds from the AC source) the TV returns to normal operation.

2) If the problem occurs while the TV is in use:
You may lose the ability to power off the TV or switch the video inputs however channel changing, adjusting volume, or accessing the menu may still be possible. After AC reset (i.e. unplug the TV for at least 30 seconds from the AC source) the TV returns to normal operation.

Sony has designed the BRAVIA Televisions to be CUSTOMER Software Upgradeable and therefore Sony will not pay a service claim on any issue resolved by a software upgrade. If a customer requests an update please refer them to the following website: http://www.updatemytv.com. If the unit requires the update, you may enter the customer's information in the website and a USB device will be sent to their address.
If a customer does not have access to the web please have them call the Sony Call Center Support line: 1-866-210-6333

If a customer reports either symptom above request that they unplug the set from the AC wall outlet for at least 30 seconds and then plug the set back in. This will reset the TV and it should work fine for several months. If resetting the TV does not resolve the issue the customer has a different problem and a service call by a technician may be required
