You have a bad micro processor on the main PCB. Remove back cover, board on right side, find part# on board and replace. Shop Jimmy is a good source for TV parts.

Your TV may be unable to detect the presence of a signal on those channels. Retuning could be necessary.

When I turn the tv on there is only 4 channels that show up. And I do have the cable pluged in


Run a full channel scan through the menu and the rest should show up as well.

Some TVs also have ability to manually turn off channels, which makes it easier to navigate when using UP and DOWN channel buttons. Instead of going to every single channel available you skip the ones that have been marked for skipping. It's a useful feature, but can get you in trouble.

Once a local hotel called us to repair 5 of their TVs and what turned out was that someone has played a joke on them and disabled all channels from the menu.

Channels are skipping


Turn the power off to the receiver and let it run its course. It should download a new program guide at this time. Another thing is to make sure you are on ALL SUB on the guide as opposed to a favorite self created guide.Thanks for using Fix Ya.

Channel skipping in Sony Rear projection KP-EF41 TV


is the channel flipping always happening at set intervals? Or, just randomly? Try replacing the batteries in the remote. If that doesn't work, start looking for other sources of IR(infrared). In some rare cases, direct sunlight on the TV will get it to do strange things.

Channel keeps skipping on rca t.v


Problem with channel skipping has rectified itself. I simply unplugged the set and and started over with remote intructions on signal and channel setting. The tv was also turning itself off and on, this also has ceased. Thanks, hope I don't need you later.
