Hey Murli, this photo is added for Mr. Chris Anderson, with whome I am communication via personal messages and I could not attach this screenshot in the message so uploaded it and pasted link in he message.
My servos are not working in auto mode, communication with Mr. Chris Anderson is pasted below for reference, did you face any such problem ?
Mr. Chris Anderson even being the owner of this website is helping me a lot and replying continuously withing 2-3 minutes of receiving my message.
Let me explain the detail of my problem here for your referene;
Sir,
Soldering seems ok as the signal pin of the Control servo connector is reaching the ATTiny45 pin #7, well as per the circuit diagram. Also I have seen the ATTiny45 with lense and found all pins absolutely alligned.
I have made sure that the GND pin of my servo jumper connecting to control connector is facing downside towards the edge.
Since I could not upload photo in this message, I uploaded the screenshot of the pcb which I have checked and verified with digital multimeter.
I'd check the soldering of the switch channel connectors (also make sure that you didn't plug it in backwards!). Also, make sure that the mulitplexor chip was placed correctly on the board; a few were misplaced (offset by one pin) at the factory.

Sir,
I do not have any good digital camera only mobile phone from which I can use but it won't take picture clear picture of the SMD components.
What I can do is that I will try to take few very closup photos of the PCB od Ardupilot if it is clear, I will send it you but in case if it is not clear then I will arrange good digital camera of my friend and take photo and then send to you.
Sir, I am good at Electronics and in soldering too, so if you could suggest which I can do with the help of a digital mutimeter.
Now I again loaded "Ardupilot_25_radio_test" from test suit folder and again checking the pulse widths of the receiver channels
I can only seen three channels in the serial window; ch1, ch2 and ch3 and no switch channel !

You almost certainly have a soldering or other hardware problem. Please send a closeup photo of your board with the RC and servo plugged in to chris@wired.com.

Sir,
"In the serial terminal, is it registering that you've changed modes?"
Sir, I have not observed that, well I can do it in next 15-20min and let you know.

Sir,
Mode LED does not change at all irrespective of changing the Ch 5 mode switch to any position.
What I can observ is that the amber colour status LED switchws off when I switch off the transmitter.

When you switch channel 5 (mode), does the mode LED on the board change? In the serial terminal, is it registering that you've changed modes?

Sir,
If I switch off the transmitter then servos chatter but even when I place my finger infront of any sensor of X-Y or Z sensor, they do not move at all irespective of the position of the control switch.
Sensors are ok as when I place my finger near any of the sensor, I get deflection reading in the Monitor Terminal window of Arduino.
