What you have wrong with your tv is in the power supply board, it is a very common problem which you can fix yourself for around $30 this is a MAJOR Samsung problem and thousands of people are having this problem. What you need to do is deenergize your tv and lay it face down on a table so you can work on it. Use a philips screwdriver to remove all the screws on the back cover of the tv make sure to remember where they go for when you put it back together. Remove the back cover and follow the two wired from where your tv power cord comes in and in the middle of your tv they will plug into a board, this is your power supply board. Look for blown capacitors, also check the fuses the tops will be bulging upward and caps have writing on them like 10v 1000uf or 2200 uf and 3300uf are the most common. What you will need to do is replace these with a 16v cap but be sure the uf number is the same, and you need 105 degree rated caps. There is also a negative side to the capacitor which is marked with a stripe and a shorter leg on the bottom, these have to go in the same way or you will blow the board, remove the board with screwdriver and disconnect all wires, now you will need your tools solder, soldering iron, and preferably a solder ****** to remove the old bad caps here is a youtube link that shows u step by step just go there and type samsung power supply repair, and whether you have a vizio, philips or another model that this is posted on they all have samsung power supplies in them so if you are having power problems this is your fix, you should be able to get all your parts at radio shack or on the web. Thank you and votes are welcome and if you cant find the parts get to me and I can help you get them

The flashing may indicate a failed power supply. Or a bad backlight tube.

Only 3 months old? Any warranty?

Considering its age I would say a defective part or poor assembly is to blame.

Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.

No picture or sound/wont power up


Your mainboard is damaged, the mainboard is the one where you plug all the cables (component HDMI), it is really easy to replace, you only need to take special care with the screws.
1. remove all screws in the back.
2. unplugg all cables from mainboard.
3. remove all srews from mainboard and replace it.
4. put all screws back and then plug all cables again.
5. double check all mainboard cables are properly secured.
6. Test TV.
7. put the back cover and secure it with the screws.

8. Enjoy your TV again.

Flashing Standby Light (6 times every 2 second interval)


A 6 flash error indicates a problem with the backlight. Your set is less than a year old and still in warranty, so you should contact Sony and arrange for a service call to get it repaired.

I have a 56" model that I have had a similar problem. My bulb burned out in <90 days. Warranty was 90 days on the bulb itself. When the TV picture goes out, the indicator LEDS blink on and off.

Here is what you have to determine:

1) First cover the left LED with a piece of paper so that you can't see it blinking. I don't know if your layout is the same as my TV. You may have to switch the paper blocking the LED.

2) Pay attention to the other LED and READ its' flashing code. In my case, the code was 2-3. It would flash 2 times, pause briefly, then flash 3 times. This meant code 23. That indicated the bulb was burned out.

3) If you look in the manual, It does have a code list of some sorts to tell you of the codes and their meanings. Hope this helps.
