motorola v60gi and hf car kit

I would call the manufacture service representative of the phone. The internal lamps are run by an inverter circuit. It sounds like the inverter may be radiating out, due to some type of internal failure.

In some models of phones, the inverter is a separate circuit module, and in other models, it is part of one of the main boards. This is not something you can go in and fix with a soldering iron and a meter. The service rep would have to replace the complete board or module, and then re-initialize the phone's programming for your provider's specifications, and re-program the subscription data. If the phone is out of warranty and this is the case, this may not be cost effective.

I have a V60, and the car kit installed. This phone works perfectly in all respects. I also have a 270c, and this one had some problems. I was able to have this one repaired by the manufacture rep while it was under warranty.

Was thinking more like solder in the hf unit. Phone's a little outta warranty. Its all good though... shoulda said the car kit is also a diy (salvaged a buncha parts I had laying around). Just tryin to find an easier way to use phone and 5-spd at the same time without the hassle of stickin something in my ear every time I get into the car.

With the sensitive issue of the very high frequencies used in these phones, if you start soldering in the front end of sensitive areas of the phone, it will most likely go out of alignment.

Many of the models are rigged so that when the case is opened, and or the boards are separated, the user account is deleted. This is a protection that they use in order to prevent piracy. The service dealer has a jig that he can use to test the phone with his test account that his bench instruments use. When finished, he has to put back the customer's account information to re-activate the phone again.

You may find it cheaper to get a new phone rather than spending a lot of time and aggravation with the one you have. This would be my approach.
