No any lighr or signal , only speakers beep sound like "fatt"

Sounds like faulty power supply or mainboard short circuit

so what is solution . pls guide , my economical condition not well to spend money for repairing from service center

You can only try with another internal power supply..not much you can do if that is not the case.. it could be anything on the mainboard , the cpu board or the panelboards but without schematics there is nothing that can be done remotely :/

Thanks for your valualbe co-operation. Yeaterday i was gone in service station , they said due to power fluctuation problem keyboard dead , need to change board and cpu . they change only board , but they said keyboard booting time taking more time than regular , its takes arround 1 min 40 sec to start regular .

If you have it loaded with locked set , it is normal to take more time.
If it works ok i wouldnt change the cpuboard anyway though

Just a thought . . . if you're living in an area where power supply is dodgy, you'd do well to invest in a UPS. https://ehomerecordingstudio.com/uninte ... er-supply/

Yes you are right sir , In my area power supply is not properly , i am starting to use ups system , Thanks .

THE SAFEST THING IS THAT YOU USE A VOLTAGE REGULATOR --- LIKE THOSE USED TO PROTECT A TV SOMETHING LIKE - YOU SHOULD NEVER WORK WITHOUT IT -
