Samsung hd tv - blacked out screen (sound no picture)

A few hours ago i was watching tv when the picture went and only the sound remained. I switched everything off and back on and i get a picture for an average of about 4 seconds before it blacks out again. I have tried the old wiggling of the cables and leaving it off for a while and nothing has worked. It is deffinately the tv as sky, dvd and terrestrial are all not working on it, but are fine on a little tv we used to test. This tv is barely a year old and i have not experienced a problem with it before. Any ideas as i am finding nothing on advice websites and forums?

Check the software and if is is not BX23U- upgrade it by downloading the software from onto a USB stick. If that don't fix the issue change the small signalbaord.

Press tv on the Sky remote

press and hold select and red until the led blinks twice
type in 0 0 6 0
press the power button, if the tv turns off then the press select and the remote should work all the tv functions.

If the tv does not turn off then press tv then the power button and keep doing this until the tv turns off, once it turns off press select and it should work.

If you have any problems let me know

Dude, better check your cable and also your TV's power management settings. This might also happen due a issue with the HDMI output of the satellite box.

Check with Samsung, this model should still be under the 3 year warranty. You are having a problem with the backlight power supply. You can look on the back of the unit for the manuf. date, if its less than 3 years then go to and process the online service request form.

I hope this helps,if so please rate our solution.

Testimonial: "Your suggestion sounds about right to me, though I'm no expert. I do have experience with bad caps in other equipment and am comfortable around circuit boards and soldering, etc., so I'll have a go at it. Might these be low-esr caps? Once again, thank you."

Sounds like main board failure and or power board failure. You need to contact manufacturer and describe problem for tech support. Some of the parts in Samsung TVs have lifetime warranties. Change out of two board is about an hour job and service call is usually comped. Hope this helps. J
