hello
I had a problem with my touch screen and after i get it to a serviceman my gps , wifi , bluetooth and phone mic were lost. so i search for a solution and i found this:
Hi. Have a look on ebay. I would recommend you buy a complete LCD and digitiser pre-assembled in one unit... These typically cost around £35 UK pounds when bought from sellers in Hong Kong. You will need a set of jewellers screw drivers (mini torx drivers), and a set of tweezers. Also, would recommend downloading a Service Manual for the Diamond if you have never taken one apart before (you can find this with Google). You need to be very careful though, because there are two small black coaxial cables inside the device that carry the GPS, bluetooth/wifi signals from the upper antenna board to the lower motherboard. These are very easily damaged and it is difficult to locate replacements. I've changed a few LCDs in the past and it is relatively easy if you are careful and methodic about taking the device apart. If you are unsure, I would recommend finding a third party replacement service on the internet to do it for you....

Has anyone had problems with their hd7 wifi cables being broken or just disconnected? My HTC HD7 was working fine and then wifi would work every once in a while and now it's completely stopped working. I was thinking about breaking it down and checking the connections and the wires, but I want to see if anyone has done this and found anything out.
Well there's a point to consider...

That the Wi-Fi is damaged... if the antena is good maybe the card is damaged, but the whole card can be replaced, it's the Radio board... the small one.
my aunt has an old HTC HD7 shes going to give me with a busted screen. Which board is the radio board? I can look up the disassembly online. Just need to know which board it is.
So my N7 won't connect to wifi, has anyone else had this issue? I'm contacting Asus Today, I believe its a faulty board.
Hi All,
A couple of weeks ago while repairing the cracked screen of my HTC One I broke the Wi-Fi/Bluetooth cable running across the phone. I ordered a new one and used the phone without it (With very poor Wi-Fi range) until the new one arrived. The antenna arrived yesterday and I installed it in the phone, however, upon booting the phone I have found that the range is still very poor.
Someone please help!!!
Thanks,

You might have damaged your wifi/bluetooth transmitter/receiver by using it without the antenna connected. Transmitters are designed to work with antennas that have calculated length and impedance based on the wavelength (frequency) used. If not using the right antenna or no antenna, most of the power is reflected back to the Tx/Rx circuitry and can cause irreversible damage.
Never use a device without its antenna or with the wrong antenna, this apply for all devices that have transmitter circuits. (WiFi routers, phones, CB radios, etc etc).
I will not explain in details how it works, if you want to read more about this, search VSWR in google.

So how can I get my phone operational again???
I love my HTC :'-(
Probably need a mother board replacement if your issue is caused by what I said
Hi guys, i bought this phone (used) and there was no issues, but in one day it stops searching wifi. It sometimes may do it, but most time it shows that there is no networks nearby.
I think i should replace wifi module, but found no information where is it on this phone. May somebody told me that?
Hello, I don't think you can change the wifi module : it most likely is a chip soldered on the mainboard, you might want to check the connection between the mainboard and the antenna ?

this might make sense, which antenna should I check?
I don't own the Xperia 10 but it can be either embedded on the chassis with little nipples pressed on contacts on the mainboard (or the over way around) or it could be "standard" U.FL connector. If your device has fallen many times they could be a little loose as these are quite flimsy
