Question about Coby Televison & Video

1 Answer

I cannot get my stations to log in and stay on my t.v. When I scan it, will only hold on channel three. I turn it off and turn it back on and three is still there. However, if I try to change the channel it will not pick up another channel and then it also loses channel three. I have to scan all over again. I have purchased a new antenna and it still does not work. Channel five popped in one time and left again. I cannot find my instruction manuel. I purchased the t.v. 3 mos ago at HHGregg. It is the 13 in.

SOURCE: TV losing its channel memory

I had the same problem. I replaced the EEPROM marked U33 (it's a 24C32 in a smd package) and the TV worked fine.
BEFORE replacing the EEPROM you have to go into the Service Menu (hold down VOL- and CH+ on the local command) and take a note of all the values, specially the R,G,B gain and R,G,B bias, in the "standard" picture mode as well as in the "Cold" picture as well as in the "Warm" picture mode.

(if you forgot to do this, here are my default values:

R gain: 434
G gain: 482
B gain: 484
R bias: 270
G bias: 270
B bias: 264

then you put the "Cold" image mode and set again those values, increasing the G bias to about 300 and the B bias to about 310.

then put the "Warm" image mode and set again those values, increasing the R bias to about 300 and the G bias to about 280)

The other values such as brightness, contrast etc, have to be left at 50.

I hope this solution will FixYa!

SOURCE: Toshiba 26AV502U Won't Pick Up Channels

Hi albertogiler, I am happy to help, you will need to attach a antenna to the tv to pick up OTA over the air signals, depending on your location you may be able to use a set of rabbit ears, I have provided a link to a site that will explain in depth. http://www.antennaweb.org/aw/welcome.aspx
Let me know if this helps and please rate this solution. lone99star

SOURCE: Dynex 32" 720 LCD HDTV - no channel listing after run auto scan?

Excuse me but the other answers are written by people who have not actually confronted the problem and are just guessing. They are all wrong. Here's the answer:

If your TV is expecting a TV input, it will keep searching for at least one TV channel on cable or antenna. If you only have a DVD player plugged in, for example, or if your cable is hooked up wrong, so there's no video signal on it, the TV will keep searching forever. (This is an unforgivable design flaw, by the way. But then, it was a cheap TV, wasn't it?)

To solve the problem, look at your remote control. You will find input buttons. Mine are small, along the top, right under the "power" button. Try pressing "video" for example, instead of TV. That stops the TV from hunting for TV channels.

Have a merry Christmas. Enjoy your new TV. Watch it in moderation and eat fruit and vegetables every day.

SOURCE: My TV Sharp 26 SB1 LCD PBS channel breaks up

Do any other OTA channels break up on this TV? Look through your setup options menu for a TV reset (memory or restore default or a similar command) . Do the reset and exit the menus (save the action on most TVs); then return and rescan the OTA channels.

On a different brand of TV this worked. The channel had broken up for several weeks; the reset was used when the channel finally became totally corrupted (no video on one sub-channel, no audio on the other).

Some tuners need a stronger signal to be stable; you may need an amplifier on your antenna.

I hope one of these ideas helps.

The tempand humidity for outdoor doesnot stay on. It goes frm temp to lines then later temp againi would like it to stay on all the time..it is a lacrosscolor forcast station


I haven't been able to figure this out yet but I can tell you it's most likely scanning the other two channels when you see the dashes on the screen. Take a look at what channel it's on when you notice the dashes. Most likely its on a channel your sensor is not broadcasting on. I'm trying to figure out how to stop it from scanning the other two channels.

I think you are confusing the channel on the tv and the channel of the cable company that is not something that you can pick up with the scan tv, scan tv is good for picking up local channel meaning air channel that we get with a antenna only not the cable chanel

Since Sirius took over, MY XM Roady will not stay on a station.


I called XM Radio and told them my problem. They told me to park my car in the drive way and turn on my XM Roady, an within the next three hours they would send a signal from the sattelite to fix the radio. Withing less than 30 minutes they had fixed it, and it works fine now.

XM and Sirius radios have merged and that is what caused the problem.
