Toshiba LCD TV/DVD 15LV505 lost channels. Rescan = fewer channels. Now in Setup, when I press the remote down-it skips the Channel option. What must I fix/change in Settings to get the Channel option?
Have Verizon FIOS. Dropped channels. So I selected Channels Auto Chn Memory. The rescan resulted in fewer channels than before the scan. So I thought to scan again. However now in the setup menu, when I press the remote down button, it skips over the Channel option. I can't select Channels to perform a rescan. What's wrong? What must I do/fix/change in Settings to again be able to select the Channel option, so I can scan for channels?

Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
Testimonial: "Hello The Knight,
Thanks for your help. But please help me understand. By system control memory IC fault, are you suggesting I need to replace the Eeprom memory? (Toshiba 15LV505 Service Manual: When Replacing Eeprom (memory) Ic.)
And follow the instructions to reprogram it after replacing the Eeprom? Or do you mean something else?
Thanks again for your help."

Need to go into the menu look for the channel setup then check the skipped channels make sure channel 1 isn't the only Channel not checked also Look at Your scanned channels in the channel list how many do you have is channel 1 it ? you may need to rescan your channels . If the TV worked OK before but Not now try resetting Your TV , BUT do this last as You will need to reset all the parameters in Your initial setup as well as rescanning channels also the Volume may blast you after reset I always install a set of earphones in the Audio phone jack first . To reset the TV Unplug it from the back of the set wait 30-40 seconds reconnect the plug while holding the Power Button Reset Your Options and Settings then Rescan your channels Don't forget the volume and to unplug earphones Good Luck
If you are using an antenna to receive broadcast TV you may have to rescan to add channel 9 back into the TV's channel list. If this does not work, it may be seasonal or a weak signal from your channel 9 broadcaster. I use a signal booster on my antenna (purchased at Radio Shack..)
You have to set the channel you want as a favorite first and you can do this from the TV. This is why the channels skip as you press up and down. Sometime or another those were someones favorite channels.
Press "MENU" on the TV until "SET UP" appears on the screen.
Now press ^ or v until "FAVORITE CH" appears in purple.
Now press < or > to display the favorite channel FAVORITE CH menu.
You will use < or > to got between "SET and "CLEAR."
So now go to "SET" and press ^ or v until you get to channel 1.
If you want to delete a channel first then select "CLEAR" and then add the channel you wish.
What your doing when you push the channel up and down on the TV buttons is going through the favorite channels. So make one of the favorite channels channel 1 and program your remote.
You will have to disconnect the TV from the AC outlet for a few seconds(10-20) then reconnect the TV and press power. You should get the start up menu after you get a picture. What you have to do is use the vol up/dn , chnl up/dn keys to select the autoprogram setting after chosing from cable or antenna signal. the enter key should be one of the DVD keys either play or stop or some other key, you'll have to experiment a little with it. There is an owners manual available at retrevo.com in case you need it, but I am posting a brief description stated in the manual on how to do this.

Using the buttons on the TV, go to the setup menu, and scroll to "editchannels" by pressing "setup" button until "edit channels" ishighlighted. Then, using the channel up/down buttons, go to channel 91and press + volume. This should add the video input to your channels. 92 is S-video. It is helpful to have what ever device (dvd player or game console) hooked up and powered on, so you know when you are on the right channel, but it should be 91.
Usually if you go into the setup menu, there is an option to allow you to either "scan" for a channel, or "input" a channel. In this case, select "input" and see if the TV will allow you to press the up and down channel buttons and go to a specific channel. If so, when you get to channel 4, press the "add this channel" option (or whatever the menu option says) and you should then be able to go to channel 4 using the buttons on the front without skipping over it.
Turn the unit off, push the setup button 3 times. Press the seek left/right to switch between cable / antenna tuner modes. When cable is selected, press the channel up/down to switch between cable modes. When the unit turns back on, it will rescan for channels.
Enter "3" or "03" on the remote and press OK/Enter. If the channel-skip feature is set on for Channel 3 you cannot get to it using the up/down buttons. Go to the setup menu to disable the channel-skip for Channel 3 if you want to tune it with up/down buttons. If you have no remote you should be able to access the menu from buttons on the front of the TV. (They may be inside a door or panel.)
