Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.

If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

SOURCE: Samsung LN-T5265 LCD tv will not power up.

Try a different power point and a different power lead. We hire out Samsung LCD's and occasionally find that it's the lead or something else in your power circuit is causing the problem. Otherwise the other issue we've run into is a faulty power supply in the TV itself in which case hopefully it's still under warranty (I believe it has 3 years)

It may have power supply problem due to bad DC power supply filter caps, or main board, backlights inverter board. It may be detecting shorted circuits so it goes into shutdown/restart mode

46" LCD Samsung TV Model# LN-S4692D I have no picture


The back light inverter board may have gone out or it is not getting the 24vdc from the power supply module. Start checking for voltage feeding the inverter board.

NO sound on HDMI3 port and when playing Blu-Ray DVD's the screen is pink


Go to the samsung website, and find out how to upgrade the firmware for your TV. You will probably need a portable usb memory stick to do so (if your TV is equipped with one). HDMI is an evolving technology, and firmware upgrades can resolve many of these quirky issues.

Here's a possibility from http://www.samsung.com/us/support/faqs/supportFaqList.do?group=&type=&subtype=&model_nm=LN-S4696D&dType=D&mType=UM&vType=R&prd_ia_cd=02010100&acc_ia_fl=&disp_nm=LN-S4696D
Which Samsung LCD TVs Have The HDMI 1.3 Interface? spacer.gif Of the LN-T series Samsung LCD TVs, those models whose last two digits are 61, 65, 66, 69, 71, or 81 (for example, LN-T4071F or LN-T466F) have the HDMI 1.3 interface.
Samsung LCD TVs with HDMI 1.3 interfaces also have HDMI-CEC (HDMI - Consumer Electronics Control). For information about CEC, click HERE.
For information about individual Samsung LCD TVs with HDMI 1.3 interfaces and HDMI-CEC, click HERE. When the Samsung LCD TV web page appears, select the TV model you want information about by clicking the drop down list under Product Finder on the left side of the page.
Though other series of Samsung LCD TVs (LN-R, LN-S, etc.) have HDMI connections, none have models with the HDMI 1.3 interface.
