I have a Samsung TXN2771HF 27" TV and the picture has shrunk to an oval shape in the center of the screen.


http://www.samsung.com/us/support/detail/supportPrdDetail.do?menu=SP01&prd_ia_cd=&prd_mdl_cd=&prd_mdl_name=TX-S3082WH Above is your Samsung support site, please go here and download your user manual, so you know all codes etc to service. Then below is a link for a Training repair manual, this will show you how to troubleshoot your issue. The problem, well symptom, is indicative of a failure in the Horizontal Drive circuitry however what exactly has "Caused" it to fail is what must be determined.,
Using the manuals you should work through all troubleshooting steps, ALWAYS start at the Power Supply, and check if the Voltages there are correct, as if they ate NOT, Nothing else can be...

But, trying to repair yourself, is extremely difficult, in any event, so, it is nearly always my professional opinion that one should always get, things attended too by a professional, and obtain a free, "Quote" from the manufacturers recommended service center, Samsung, in your case, please contact a local or head office and ask for a referral to an Authorised service center. I cannot stress how important that last point is. It is even worth the cost of shipping. You see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace.

I have a Samsung 27" TV and need to set it on channel 73 to get a picture from my Satelite Dish. The highest channel the tv goes to is 69.


Set the TV to cable tuning mode and use that channel 73. You have it set for air now so it can only tune to channel 69.

Constantly flashing "Not available"


I have the same TV and had the same problem. It's due to a failure in the front-panel buttons, which are very sensitive. Mine got so sensitive that they were registering presses all the time, even when nothing was near them.

Since I never used the front-panel buttons, I solved the problem by opening up the TV and disconnecting the front panel from the rest of the TV electronics. This was somewhat difficult to accomplish due to the fair bit of TV disassembly I had to do to get to that connector. After I put the TV back together, the "NOT AVAILABLE" problem was solved, but somehow I had damaged something else--the tuner, composite, and S-Video inputs lost their color and now only show up black-and-white. (Luckily, I only use the component video inputs, which were unaffected.)

No Picture, No Sound...Please Help


The most common problem this set has is the Horizontal Output shorting, usually caused by the High Voltage transformer drawing to much current. Whether it's the high voltage circuit or the power supply, having a tech look at this set would not be cost effective. Start looking at the newer technology. Hope this helped.
