Hello,

Pull the back cover and check the capacitors on the power supply. If there are any that are bulging or show signs of fluid leakage, replace them. If that doesn't fix your no picture but sound issue then you have a bigger problem. You can do it yourself pretty cheap and its not that hard. Just make sure you use the proper replacement capacitor, but if otherwise

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

often that *needs* to be done in a service center as there are some adjustments to be made after replacement.

Hope this helpout......

Samsung 32 lcd tv backlight off after 4 sec. audio ok


If your TV is staying on and you hear audio after the picture goes dark, then you have a problem with a CCFL or the inverter circuitry that drives them.

Most likely an inverter problem.

Like a bad xformer (usually fogged up plastic wrapper)

Or a bad cap (bulged, swollen, cracked)

Or maybe a shorted IC or transistor (test for short circuit between the different pins of the device)

Cannot view tv program while recording on VCR


Hi and welcome to FixYa,

Initially, pls set the Samsung LCD TV to the Source selection as if watching a playback evgen if you are going to do a recording.

If that does not work, pls postback manner of connection (cabling) from Cox digital cable system to Philips DVD/VCR to Samsung LCD TV LN-T3253HX/XAA .

Good luck and Thank you for using FixYa. Happy Holidays.

Samsung LN19A330J1D TV buttons on monitor don't work


You may have to enable them within the menu as these type of TV's are often used in Hotels and Hospitals and what not. Disabling the buttons on the TV prevents customers from messing with the settings of the tv and allows the business to use whatever custom remote they prefer. Check the on screen menu and look carefully through the options, you should find it there.

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.

SOUND BUT NO PICTURE


Defective lcd controller board. If the repair company and you are willing to wait less that 400 dollar repair. If not You are looking at having to replace a panel time to throw it away. The Lcd Controller board is available for this model.
