Board level TV repair

[Bishoop]

I have an Advent TV that has the RF input connector broken off. I removed the back to see what I could do to make repairs.

The RF connector is an integral part some "module" that is soldered to a PC board.

Anyone have any ideas on where to find board level components so I can make the repair myself. I'm just not willing to put out 100 bux for the whole circuit board.

Thanks....

I think you would get a better response in a group like sci.electronics.repair

YOU ARE CORRECT

Thanks for the tip.

Took apart the module with the missing connector and I think I have almost completed a repair. I'll be powering it up shortly.

Hi, If I were you. I'd solder a piece of coax onto the board, epoxy the joints, then sedure the coax with tie clamp, then attach a female coax connector on to it. It's common problem, PCB mounted coax connector breaking off. You may need to repair the dmamaged circuit trace on the board first. Good luck, Tony, VE6CGX

My repair is pretty much what you suggested. Powered it up and all is well.

I used to repair vcrs, Had many F connectors ripped from the RF converters. The converter material would accept solder so I put the connector back in, got as good a mechanical connection as possible and soldered all the way around the connector. Made the center pin connection and tested it. The insulating material in the center will melt so you need to tin everything and then solder part then cool it, then solder more and cool it etc. Use a damp cloth to cool the part. Mike

If this module is a large rectangular metal can, then you are looking at a tuner. These can be purchased as complete modules, or as refurbished exchange units, or you can repair the existing tuner by removing the broken connector and adapting and soldering a replacement connector to the tuner housing.

IIRC, I used to use this type of adapter and cut the bottom end off:

You will have to solder a short wire between the centre pin and the tuner PCB. Before soldering the connector to the can, you should roughen up the contact areas with sandpaper.

As I indicated in an earlier reply post to this thread I was able to initiate a repair and the TV is working through the RF connector just like brand new.

Thanks to all that replied with helpful tips.
