Default 8700c Radio Issue

Please Login to Remove!

Please help! 8700c running on Cingular works flawlessly until you try to turn radio on. Stays on message "searching for network" for a while and then reboots. Other than phone/ radio operation, phone works flawlessly and does not crash. Any ideas? Help would be much appreciated!

If Cingular coverage in your area is good then I'd say there is a problem with the device.

I have the exact same problem with a 8700c that I bought on ebay. The phone has a very very poor signal strength. I ended up shelling out the full retail price for a new one at a cingular store. The phone I bought on ebay was used but was in very good cosmetic condition. I think there is definitely a problem with the radio in the device. As an example my brand new 8700 has a signal strength of -68dBm (perfect) on the second floor of my apartment. Meanwhile, the ebay 8700 has a signal strength of -110dBm (extremely poor). I have taken the ebay one apart hoping to find something simple like dirty antenna contacts but everything was perfect. I am going to assume that the device was simply used a LOT before I got it. If anyone has any ideas on how to repair/replace the tx/rx components in an 8700 for a reasonable price it would be much appreciated. I do a lot of work with small surface mount components on pc boards in my company. It sure would be neat if I could figure out a way to repair it. I have 2 8700c's that are in perfect cosmetic condition but one of them is barely useable due to the radio problem. I don't think that it is a widespread problem with the 8700 because there are no other reports of it on this forum and I absolutely love the new one I bought in the store. Sure was expensive though.
