RCA CTC146LA Tuner

Are you sure the tuner is bad? Most of those I have seen had a bad (drifted) aft and video detect coils which mimmick a bad tuner symptom.

----------------------------------------------------------------

----------------------------------------------------------------- Sounds like the coils have drifted. You will need a cable tv signal generator that will generate channels dead on frequency to verify the adjustments. The actual fix is to replace both the aft coil and video detect coil and then do the alignment. It still could be the tuner, but the 10-15 seconds to change channels is usually the aft circuit delay.

What you want to do is program the tv set to receive only one channel, the channel you will be using for your generator. Channel 3 is a good start. Mark the coils position first and keep track of how many turns you are doing, it should not take more than one turn either way to show an improvement from normal drifting of the coils.

Now using the channel up button on either the tv or the remote control, keep pressing the channel up button going back to the same channel. Watch how long it takes for the tv to try and lock as you slowly move the coil. When the channel change is almost immediate the aft is in the right place. Then fine adjust the video detect coil using the same method until the image looks the best and you still have the fastest lock in on the channel. The final test is to auto program the tv on cable and make sure it does not miss any channels.

It is (was?) in Quebec...

I don't know how old some of these directories are, but there are telephone numbers...or have you checked this out already?

I've never had the coil drift problem on a CTC146. On the CTC149 and
