Check the inverters and the connections to the CCFL tubes, they are the ones that generate the light.

After a storm still have sound no pictuer. caps look good ,fuses check good .tv 23months old little usage.


Check to see if you have 24vdc comes out of the power supply, this 24vdc is used for the backlight inverter board, if you do have the 24vdc, then check the fuses on the inverter board.
You may need the power supply module or the inverter module.

When i turn my tv on 3/4 of the right side of the


The problem is most likely in the image processor area, or the backplane circuitry on the screen itself.
The service rep would be equipped to properly service your set. You should call LG to find out who in your area is able to service your set.
If the set is out of warranty it could be fairly expensive to service.

LN 4661F -won't turn on -clicks -red dot flash


The capacitors in the samsung 4661 are inferior, this happens to all the ones in this line.

If you are feeling handy and don't want to replace your circuit board, here's what you can do.
Remove the 30 screws on the back of the tv. and the plastic shell will lift off.
There are two boxes, a large almost square one to the left (thats the power board, with the bulging capacitors) and a slightly smaller one to the right. (thats the cpu and circuit board)
You only care about the power board for now.
MAKE SURE YOU TURN OFF YOUR TV FOR AT LEAST 12 HOURS SO YOU DON'T RISK SHOCKING YOURSELF.

Remove the 6 or 7 screws from the metal casing on the left.
To unplug the connectors, either press your fingers at the sides of the connectors and gently lift them off, or pinch them from the small tab in front, and lift them gently off.
Remove the metal casing.
Unscrew the 5 or 6 screws holding down the power board and lift off the power board and take it to any monitor repair shop and ask them to replace your capacitors on this board, with more powerful ones. (usually 16v instead of the low 10v that come with it)
Just tell them its the samsung LNT-4661F and they will know the problem as most people who own this TV have called them.
Or they can google samsung 4661 capacitor kit, to see what capacitors they want to install.

Hope that helps someone, as I had to do it.
But it saved for $400.

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.
