need a 455KHz source,
i wonder how cheap one can be made!

Checking levels isn't much good at this point, since you are lacking an RF generator and other test equipment. Unless you actually find a faulty component, I think this is as far as it goes without firing the parts cannon at it. The only thing what you may want to do is to compare a working one with this faulty one and do some voltage measurements and compare them.

My next step would be doing a full FM Rx alignment and see what that would do. Then again... you don't have the necessary equipment.

Oh... shoot. In that case, I'm stuck. Before I started this topic, I actually called a few local repair shops in my town to ask if I can bring the radio to them to have a look at the problem. All of them said "We don't do that, we don't fix eletronics that old". I guess they got used to to microprocessors, chips, "all-in-one" circuits and what not. Old-school electronics repairman is impossible to find.
So, I tried my luck here and all of you people who stepped in and guided the noob me through all we have done, ant that is really amazing. From a non-working radio and a 40% lit display we got to an almost fully working radio, sorted voltages and a VFD display that illuminates like a brand new one. For all this I am eternally grateful. I am still clinging to some hope that there could be something else to give a go to, still hoping.
OK, tomorrow I'll have some time to open up the working unit again and compare the voltages. I guess I can use it as a reference point, since it uses the same power supply, maybe the reading will really tell something. Hopefully.

Makes me feel even older now.
