Question about Samsung TXN3245FP 32" TV

1 Answer

Samsung Flat Screen SDTV Model #TXN3245FPNXXAA

This unit has been in use, since October 2004. Up until about 10 days ago, it has been great. It has started loosing the picture & sound, on just certain channels (in a certain range). We have expanded basic Cable, without a "digital box." The range of channels effected is from 29 thru 45. It has never involved a channel lower than 29 or higher than 45. If one of these channels goes out, at least one or two more right next to it also goes out. It has been 29 through 31 (or 32), 31 through 33, 34 through 36, 37 & 38 and (just once) 38 through 45. The channels mostly effected are 30 & 31. It seems that now either of these two channels only need to be on, for 5 to 7 minutes before going out. The "snowy" pattern IS NOT like what you get, if the cable is disconnected. It actually has a "digital-type" of patterns to it. I called Tech Support, who said the parts would be covered but NOT the labor (even though they also said it most likely was the cable, as the "tuner would not just involve a small amount of stations"). They said to run a cable from the outlet in the other room (which that tv has not been effected), to check the outlet. It only took about 3 minutes for channel 30 to go out. I contend this is a TUNER problem and just can't believe that a $500 tv would go bad so soon. Does anyone have an idea or has anyone heard of a similar problem???

    Thank you for your previous comments. It turns out the tuner needs to be replaced and it's ALL on my "dime." I've ordered the part, direct from Samsung and have purchased a PDF Repair Manual.

    I am planning to have my son help me with this replacement. He used to work for a Stage/Concert Lighting manufacturing company and both of us are very "handy," with a good amount of common sense.

    Do you feel we have a fair shot at completing this task?

    I just feel so "taken," after spending $500 on a TV that has gone out in less than 2.5 years. I've never had a tuner go out, in under 20 years. It truly bothers my wife & I to think that we would possibly need to replace an item this expensive, in such a short period of time.

    Thank you,

    Hello "Guest,"

    Replacing the tuner is way more than a "do-it-yourself" project. It requires removing the old one from the soldered circuit board and re-soldering in the new one. The pins are very close together and one wrong move could ruin the unit.

    At this point, I am left with two choices... Either put it on channel 3 and use the VCR as a tuner or take it in for service. Right now, I'm still using the first option.

    Sorry I couldn't be of more help...

    Hey I have had the same exact problem. Do you think getting digital cable would fix the issue?

On what you have explain you are to check with cable provider if your tunner was the problem all the channels would be affected try plugging another tv to the same cable and see what it does if you get the same symtoms then it will be from the cable company.if not then you will have to take your tv to a repairman and have it check probably a component in the tunner circuit is bad.or you tunner will need to be replace. good luck

Why is my Samsung 32" HDTV shutting off at 6:00 pm everyday?

Being a newer tv it would most likely have some internet connectivity. Check in the settings to see if has an option to update. That may or may not fix the issue. It's worth a try though.

The model is Samsung LN-T4661F. It power cycles at least 3 times every time I turn it on. Once the screen comes on there are, most times, pink pixels randomly all over the screen. I have to turn it off...

good day .maybe theres a defect in the board causing the screen changes abnormally. maybe the screen module is defective. just consult that problem to samsung service center to fix your problem.

I have a Samsung LN-T3253H that I purchased a little over a year ago. One day I turned the TV on the screen was black with sound. I had no prior warning, the tv worked great up until it broke. I am so...

Call Samsung they may be willing to cover the repair since it so close the the end of the one year warranty. They are a good company and will usually work with the customer. Any brand of tv can fail and do at any time. Trust me on this. I've seen them do it before.

I have a Samsung 50" plasma, that has been blacking out over the last 6 months. A 9/2005 set. Now its practically unwatchable as it happens 3 times in an hour. Its not heat related - I have a high volume 9" fan activated on TV power on. Turning the set offf/on usually makes it come back for a now short while. Considering to go put it in the back of my pickup and park it in front of Best Buy and discourage Samsung purchases. This is the 2nd Samsung TV I've purchased (the other a 32" tube) I gave to my folks a couple years ago and its gone bad as well. Samsung product may look good, but their video engineers are not.

Samsung 40 no picture

If it is only 6 months old you probably still have a warranty. This is definitely a hardware issue, and unless you are comfortable taking your new TV apart, I would contact Samsung for repair.
