How do I fix the FM tuner to pick up FM signals?

I think you might have fault in the FM tuner section. Most of these are done by a single IC, replacing that will cure the fault I suspect.

No response when switched on

There is an internal fuses in most of the radio's for the low power circuitry. Open the case and have a look. In the 706, it is on the PA board and is a 3AG style fuse. Do not replace this fuse with a higher rating than it already is. A higher current rating will damage the radio beyond economical repair if there is a problem. If the fuse is OK, then take it in for service. There is very little, if anything, that most hams can do at this point as the electronic components are too small to work on without the proper tools.

Check and replace its main system control memory IC. If this IC is faulty, auto tuning will not work, or, the TV will store any received channels. If the TV do not tune into channels too, the AGC voltage to its tuner, and tuner itself should be checked.

My technika tv will tune in ok but turn it on the next day it needs tuning in again

Two components in the main circuit to your TV should be suspected. The first one is its Tuner itself. if tuning frequency of the tuner drift with change in atmospheric temperature, or if the Main system memory IC do not store the tuned frequency well, this type of fault will happen. Anyway, the work is a skilled one, and a user who have no knowledge about electronics cannot make this fault right. It will be best for you to contact any experienced service technician.

Hi, I have a Harman Kardon AVR 300 that I picked up at a local sale. When I power it on, it switches fine to each input except the AM/FM tuner (the preset, tuning, & tuner mode buttons don't seem to...

Hello Sir, Hi, you may try the following
  1. try cleaning the switches
  2. if this does no solve the problem, its the selector circuit. this may be digital, so you need to search the IC that selects the FM mode both with tuning. this is fair complicated.
  3. buy a cheap separate FM tuner, run it on auxiliary input.

What kind of antenna tuner do you use? (automatic or manual)
Personally I use the LDG AT-7000 and a G5RV. I have absolutely no problems on any frequency.
