What type of TV tuner card do you have? Model No.?

type the murcury tv tuner card model number and type free download on the google web u will get the solution ..or go to the murcury main web page ..

Tuners are available as a unit.
Repairing is not possible. Contact SAMSUNG with your TV model no or the part No. indicated on the tuner box.

There are two types of tuner 1. voltage synthesized. 2. Frequency synthesized. Check the type that is used in your TV and buy.

You can replace the whole tuner if you are proficient with soldering. I would try PartStore.com first and you usually order by model number here. If the model is listed you can scroll through the parts available to see if the tuner is shown. I have worked with them and have had very good service and fair prices. Good luck.
