Board level TV repair
On Sun, 8 Jun 2008 13:53:48 -0400, "Bishoop" put
finger to keyboard and composed: 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.... 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: http://www.futurlec.com/Pictures/AV023.jpg 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. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

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. |
