p800 no network


As above got a p800 showing no network stright away, now I guess this is due to the fact that the car airel part has been ripped off, any way to repair this or by pass it? (with out getting a new part) also I can't get ufs to read the phone just keep's going to charge any way round that as well?

just short two points where the aerial used to be. the connector is made up of 4 points. Each pair of these points is short to the second. What i mean is, u av 4 points with 2 points shorted together but isolated from the other two points which are also shorted. Now that the connector is no more there. U can get a signal by putting a jumper wire (or shorting) the point going to the PA to it continuous pair (assuming the connector was there. I hope you understand. Ill try to take a cut out from the service manual and post here. good luck

I get the bit about shorting out the pairs, but a jumper to the PA that bit has lost me, right off to short some points out.

Many thanks

Also if you need to mail big stuff send it to here

u dont reaslly need a jumper to the PA. just join the two points (that's just 1 of the initial pairs i was talking about b4) that have been left open due to the missing ext aerial connector. The second pair of points u could still leave open (they dont matter). What matters is the pair of points linking to the PA. Good luck!
