I have a cable connection. A couple of days ago while changing channels, one channel (52) went all fuzzy grainy on me as if it's a little out of focus. Other channels all seem to be as clear and sharp as they were before. Another TV on the same cable connection has a sharp clear picture on all channels including that one. It appears there is a problem on this one channel on this one TV. Any ideas? Any way to adjust the reception/ focus on just one channel?
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.

Normally if you can get/program Chs 2 and/or 4 as well the other channels, then Ch 3 should also be programmable. If this is not possible, perhaps you can try to manually program by selecting "03" and add to the memory "+" in some brands/model. If this is still a no go, perhaps you should seek the services of qualified professional since this would apparently be an internal software problem. You can also try a hard/full reset by unplugging the TV from the mains for couple of hours or as prescribed by your TV's user manual.
If the TV has Video input features, a possible temporary work around the TV's Ch3 problem is to use the Video1 or the Audio/Video INput of your TV and use an old VCR to connect to your cable box. Remove the coaxial cable from your cable box to your TV and connect it to the RF/TV INput of your VCR. Use a 3 way RCA to RCA connector (usually Yellow, Red & White) to couple the Audio/Video OUTput of the VCR to the Audio/Video INput of the TV. Select Video mode in your TV (so it doesn't matter even if you cannot program Ch3). Power up your VCR, select Ch3 in your VCR's tuner. I assume that to select channels you wish to view, you use a remote and channel selection is done in your cable box.
What worries me is "...went to a fuzzy black and white screen..." which is indicative of another fault.
Hope this be of some help/idea. Post back how things turn up or should you need further information.
Good luck and kind regards.
I have a 2000 model RCA P52923 and I had the same problem occur a couple of days ago. The sound hasn't worked for a couple of years, but the TV is connected to an RCA surround sound to resolve that issue. Most recently, while watching TV, it began to start scanning channels by itself. I shut it off and unplugged it for a couple of days, but each time that I turn it on, it begins to immediately start scanning each channel. Neither the remote, nor the channel buttons on the set are able to stop the scanning, and neither of them will perform any functions, including turning the set on and off.
Any advice would be greatly appreciated.
well most lcd and plasma tv's above 36" will look grainy on standard definition because they are made for high definition so if you do not receive a high definition signal to your tv then that would most likely be the problem
This is an indication of a bad ground connection. Since you have replaced the cable and splitter, it suggests an internal grounding problem. If you can solder and can get to the tuner, resolder the ground points within the tuner and update this with the results.
Normally grainy pictures are a result of poor ground connections, although usually for more than one channel. Check the cable connections first. Otherwise all I can suggest is to have the tuner replaced.
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.
