I have a toshiba tv 39al900a which was won in a raffle. When you turn it on it says please scan channels.t.


The first step is to make sure you have good batteries in the remote. The ones included tends to be cheap and you have no idea how old they are.
Here is the manual, page 12 explains how to use the remote and the next few pages cover the initial setup and scanning of channels.

If the remote is still not working, get a universal remote to replace it. This link gets you the codes to program the universal to work with your TV. http://codesforuniversalremotes.com/universal-remote-control-codes-toshiba-tvs/

I do not know how to do a channel scan, can you help me please? I seriously thought that I could find anything online but I have not been able to find how to channel scan this tv.


What brand/model TV do you have? If the TV has several input options, make sure that the TV is set to the TV mode. (Use the Input or Source button on the remote, some TVs have this on the TV as well but not always)

Some can only do a channel scan with the original remote. My old Emerson CRT (~20 years old) launched a channel scan when I pressed the Add and Delete Channel buttons together on the remote. Fortunately even when most of the buttons failed on that remote, the channel scan still launched.

Other TVs from that time frame have an channel scan button in the control panel. Often these are hidden behind a panel to avoid accidental resets.

More modern TVs usually have the scan as part of the menu. Depending on the TV, press Menu on the remote (or if available on the TV (sometimes can be done by pressing Ch+/Ch- together)). Then look for a Setup option or a TV icon. If you have a Setup menu, you will then need to go to the TV submenu. Then find the option for setting the input signal (TV/cable) and then you should be able to launch a channel scan. (Usually the Ch+/Ch- (up/down) and Vol+/Vol- (left/right) buttons will navigate through the menus.)

Unfortunately, without the make and model, I can't give you any more help. Please write back with your brand of TV and I'll check if I have the manual in my stack.

(low end universal remotes do not always include the menu or source button. If your TV doesn't have them, you may need a different remote. The ones that can be programmed via a USB connection are the easiest to set up.)

Radio Shack (Realistic) PRO-2020 Scanner stuck in Scan Mode


Sounds like old age - the 2020 is nearly 30 years old! Have you tried just using the LOCKOUT feature on all channels except the you want? How about just programming the same frequency into all 20 channels?

ok i am typeing this right out of the book/
operating your tv: Once you have connected your tv to an anntenna or cable system,plugged the tv in, and put batteries in the remote, you are ready to use the tv. the first thing you should do is program your tv so it memorizes all of available analog& didgital channels.PROGRAMING YOUR TVS CHANNEL MEMORY: your tvs memory determines the channels thet are available using the "up ch down" buttons. if a channel is not in memory . you can tune to it with the numbeer buttons, but not with the up and down buttons . follow these steps to program your tvs memory:
1) Preset
press the MENU button twice to enter preset menu

To memorize all available analog and didgital channels
press the ch down button to highlight FULL SCAN then press VOL.+ to begin channel scaning, the channel scanning starting with analog channels then to didgital channels. after your tv finishes memorizing the channels, it will return to normal tv viewing. I hope that this fixes your problem thats just the main section on the programing part so if you need further info just ask!

i had the same problem with a 32 inch and i kept "clicking" the channel changer on the remote to force the tv to go to another channel (that had previously been selected during the initial auto scan) --- still trying to figure out why the tv locks onto the scanning for channel

TV scans for channels and wont stop.


I've seen a similar problem like this caused by a stuck button either on the set or the remote control. IF one button has no effect then that's the one that's bad. This might also be your problem. If not then something has failed in the system control circuit. Stargazer
