Video through RF cable no longer works

Hey, We had a pretty strong thunderstorm recently, and one really close lightning strike. And no longer does the television video work through the RF cable. I tried putting it directly to the tv, to no avail. So now I have it going into the vcr and video/audio out to the tv. In other words video still works fine on the tv, just not through RF cable. I am guessing the lightning fried something. It is a JVC 36" tv (CRT), attached to a base, so not easy to move. My question is how easy, or not would it be to fix, and what would it cost? Thanks very much!

Hi Bozlo...

Got me confused already, and I expect the others will be too... :)

Video through the rf cable? Can you explain that differently, or perhaps in more detail?

Take care.

i assume he means the 75 ohm cable that comes from the cable company then out of his vcr

its a real bummer if you have pip and it has to be air/cable or video in

i prefer video in cause i got the diewrecktv do you just get the fuzz on channel 3 even with your vcr on and tv video set to video?

is there any settings in the tv like air/cable or any other switches or menus

Yup, RF as in seen here:

This tv doesn't have PIP, so no worries there. When the RF cable is in, direct to the tv, or via the VCR, it is a black screen, and the channel numbers show up, as does the audio that accompanies the respective channel. I suppose I should have mentioned that. I tried rescanning for channels, and it just brings them back with audio. This is the old style tv, the cable comes from outside, from the cable company as you said, and to the vcr/tv.

Using the tv with video output (composite) from the VCR is just fine for now, but eventually maybe it would be worth fixing, as nothing else is wrong with the TV. Unless it would cost too much, since CRT TVs are going the way of the Dodo. Thanks again!

The tuner module has been zapped, You will have to have a tv service tech repair that as it is not a user repair job. You are lucky in that it didn't zap the whole set, but still the repair will not be cheap. Can't guess on cost for your area, but you can figure at least 100.00 Us dollars to fix.

hmmm sounds like the video detector or buffer or something in that area is blown. If you change channels and get the correct sound for each channel that says the tuner, IF, and Audio det are OK. It's a little weird that just the video is gone as those things are usually all in the same IC. Perhaps it's a buffer external to the Video but before the switch that selects tuner or composite. It could be a simple repair or not depending on the set is done. Personally I'd do the cable to VCR composite to TV setup.
