Sometimes when I turn on my Tv.. all the channels play the same channel. If I turn the TV off, I have just a fuzzy screen... then I try to do easy set up with no success. After a few hours,the TV works fine. I have had my cable/signal checked multiple times with no problems found. Any suggestions? Could this be the TV? Any help would be appreciated.

Re: Same channel on all channels
Yeppers it certanly sounds like the tuner control curcuit or the tuner itself is bad. With the back off the set and the tV on, if you tap on the side of the tuner does the set start to work? if so the tuner has to be replaced

Most likely it needs a converter box. To see for sure, just turn it on and look at the channel type.
1. Channels are displayed as decimals, such as 17.1, 17.2, 17.3, 18.1, 18.2, etc. In this case it's a digital TV which needs only an antenna. Also usually TVs like this display no signal as a blue or black screen, though sometimes they can have the fuzzy gray screen.
2. Channels are displayed only as single numbers, 1, 2, 3, 4, etc. Most likely the screen is gray and fuzzy, maybe making a loud fizzy noise, when you have no signal. It's an analog TV and you need a converter box.
This has hopefully been resolved for you, but if not, here are some steps to go through. The black box that comes on the screen is usually signaling that closed Captioning is activated on the tv. Closed captioning does not run through the DISH Network receivers, so you can turn that feature off in your tv settings. The fuzzy picture could be a few things. You will want to check that all of your cables on the back of the receiver box and tv are tight as possible, and also make sure that the tv is on the correct channel. If you are in the room with the receiver, the tv will need to be on channel 3 or 4, and sometimes an input; usually video 1 or 2. If you are in a number two room, where there is no receiver, than you want to make sure that the tv is on channel 60 or 73. I hope that this helps!!!!!
The TV is usually set to Channel 3 or Channel 4. You may have a switch on the back of the VHS recorder near which is marked Ch3 Ch4.
Once you correct this, try the following procedure.
Some VHS have a tracking button that allows the user to tune to the best
signal. The tracking can also be done from the remote controller.
Usually that tracking function is used as follows. While
movie is playing on the VHS unit and signal gets fuzzy, press the
channel key repeatedly (for example >> to increase the channel
number). f after awhile pressing the same channel change button does not
find a better picture, you should press the other channel change button
(to decrease the channel number <<) to see if the picture
If that does not work, IT DOES NOT MEAN that you tv/vcr
combo unit is defective. It could just be the movie. The tape is
magnetic and it might have been accidentally demagnetized.
picture is better with another movie/tape, your unit is definitely OK.
Tis is an ongoing problem I seen increase alot over the past few months. From what I can gather, all the channels being broadcast over going from the analog to digital, there's no big suprise to anyone. However, the change from analog to digital is changing at a faster rate, so when you look at the TV some channels will be fine and others will have grey lines, fuzzy picture. The only solution-you need a TV with some kind of digital tuner. On the TV itself if the (TV has one) it will say "SD" or "ED" which stands for standard digital or enhanced digital.
If you have a good cable signal connected to the TV and it receives channel 50 nice and clear but all lower channels have nothing but snow, then the tuner is defective and needs to be replaced. This is quite an easy thing to correct. Sometimes resoldering all connections inside the tuner will bring it back to life, but in either case the set should be serviced by a qualified tech.
