Top 20 Samsung LN-T4661F 46 in. LCD HDTV Questions & Answers

Check the internet. Most likely a series of cheap capacitors. Replace them all (the ones that match the culprit). ~.20 each US.

Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

hi this could be a tab/ribbon fault, there are ribbons attach to the screen at the top there's chips installed on them. when one is faulty they heat up and make the ribbon start to flex and move causing this fault, hope it helps regards shaun

Anthony, you did not list a model #. If you would it makes it eassier to determine what may have happened with your Samsung TV. An LCD would start with LN46----.I have had screen issues with some samsung product. As well as other makes of televisions that use Samsung 46 inch dislay lcd.

It sounds like faulty capacitors inside the set, this model is known for this problem. Are you looking to repair yourself or just looking for a repair estimate?

One among the back-light CCFL lamp has burned out. Replace it.

Just visit this site 'electronicshelponline'. Type in this site name to your browsers search box. It is a blogspot site, purely technical. It is in English language. Has all details about the blinking codes to Samsung TV. you can get details about these blinking codes from here. Pull up older posts there. The site name is 'Electro-help'

the samsung LNt 4661F has been known to develope flex tab bond issues which will cause line to run across the screen and you can also gt darker bands that run across the screen when the tab bonds fail. usually flexing the screen frame or a light tapping will allow the lines to disappear when its warm if its a tab bond issue

Hi most likely yes it is your panel. However there is a chance that it could be your t-con board. I would say 80% Panel 20% chance that it might be your t-con board. The T-con board is fairly inexpensive compare to teh screen so I would give it a try first. You can get parts at www.interliquidparts.com

change your tv configuration channel type is probably cable instead of air

Is it like this?:http://i691.photobucket.com/albums/vv275/oldskewel/samsung_LNT4661FI think I have the same problem on my LNT4661F. I happen to also have a 4061F and just temporarily swapped main boards, which confirmed that it is NOT the main board which is bad. Swapped LVDS cables to confirm that's OK too. If you replaced the T-con board, then that leaves the power board or the panel. Did you make any progress on this?All the caps on the power board look good, but I hear a whistling noise from one of the power transistors.

Capacitors are bad. Samsung will fix for free call them.

Power supply board seems defective, replace it to solve the problem. Required board is available HERE for $65
Thanks.

Your problem is typical of Samsung LCD TVs. The capacitors on one of the internal boards are rated at 10V and should be higher. If you open the case, you'll see bulging capacitors. If you can handle a screwdriver and soldering iron, you can actually fix it yourself with a few capacitors from an electrical supply store. Simply read the specs off the bulging capacitors and get a higher voltage-rated replacement. For exmaple, if the capacitors say "1000uf 10V 105C", you would replace them with "1000uf 35V 105C" or similar rating. Or an easier method: Recently, Samsung themselves have been making repairs as it is such a widespread problem. Call Samsung at 1-800-726-7864 and they may just repair it for free, even if its not under warranty.

Press and hold TV, then OK at the same time. Let go of TV and OK, top buttons should quickly blink red then stop press the code 1019 then hit the bottom right button marked ENTER or OPTIONS
Remote should now work with tv.
To control volume and power at the same time... Press and hold STB and OK at the same time, let go, red blinking up top enter the code 977 STB should blink red a few times.
Hit STB, see if TV volume adjusts Hit POWER. see if both STB (Set Top Box) turns off and TV turns off.
All should be good.
If both TV and STB do not turn on/off, repeat the process for the code where you enter 977

unfortunately there is no way to fix this short of taking the unit apart and checking for loose connections, which may cause more problems than it solves, either take it to a tv repairman or hope it doesnt get any worse :s

This model has speakers. If you are trying to connect external speakers i.e. a home theater system, receiver or a sound bar you have a couple options.

This television only has hdmi inputs so you cannot connect the external speakers with hdmi cables. The television would have to have and hdmi output.

Now in order to use hdmi you would have to connect all your devices to the home theater and then go hdmi out from the home theater to one of the two hdmi inputs on this television. Then you would leave the television on that hdmi input at all times and switch devices with the home theater remote.
All the devices would be connected from their respective outputs to a respective input on the home theater.

Another option is to connect a fiber optic cable from the television to the home theater.

Another option would allow for stereo sound but not the higher quality surround sound. You can connect from your televisions red and white RCA outputs to the RCA input on the home theater.

Inspect the power supply DC filter caps and DC output voltages first before buying any parts.
