recently , i purchased a fly sky simulator from one of my fren..
was working well initially...
but after 3 uses, it is  not responding...
when i opened the simulator , found 2 resistors blown up...
not know about condition of i.c...
can anyone suggest me a solution?
or it,s circuit.
thank you

Can you show the picture of the circuit board so that we can help.

hello sir
i m posting pics but r blurred due to small components and my 2 mp camera.
ic used is em78m and below written  c649l.
i highligted 2 blown components.
thank u

some more pics..

simulator pic

no response...
may b due to poor quality pics...

Aditya, it's not just the quality of the pics. This sort of issue cannot be sorted out easily.
Most would suggest you to buy a new simulator because even if you find replacements for the burnt-out components, it would be really hard to reassemble everything (as most of them are surface-mount). All you can do is find out why those components burned-out and try not to make the same mistake again.
Why don't you check out the 2.4G radios from RcBazaar, they're really low priced.

what made u think its the resisstor. i usually use my MulMet to check the componenets and if the PD is high i will conclude its that component wich is faulty... Those ICs wont be readly available, lukly this did happened when u where flying

Cannot see the picture clearly. But the things like that the resisters are used in the timing circuit in conjugation of joystic pots. So, values could be critical.

First trace what is connected with the two terminals of the resistances ? Then check if the similar circuit available for other channels or not if this is used in any of the channel. If yes, then you can see the other channel good equipments and can check the value and ashume the required value.

If this is in power line circuit, then it may be voltage regulating circuit that supply the microcontroller or Digital IC so that timing component can work irrespective of the supply battery voltage. So, it may be zenardiode with resistor or 3pin voltage regulator or may be an inductor too.

So, please take picture more clear and post. TO take clear picture, maintain minimum distance from camera to PCBs and use optical zoom. Moreover use sunlight or other high intensity light and avoid flash. Your pictures can be clear and we can easily solve the problem.
