It turns on for 3 sec and then turn off - Sharp (RLMPF0014CEZZ) Projector Lamp for XV-H30U, XV-H30U, XV-H30

whatever problem you are having with brivis buffalo, the first thing you need to try is RESET. This is how you reset.
1. turn off your heater from wall switch for at-leat 5 sec
2. turn on your wall switch for 5 sec
3. repeat step 1 and 2 for atleast 3 times within 60 sec

my brivis buffalo 20 was keep turning off after 30 min. RESET fixed my problem

Try removing the battery and restart. Could be a bad memory module, fan not working, CPU going bad, graphics chip overheated and going bad. I assume it is out of warranty so you might have to take it to a repair shop.

Go to Sony authorized service center & get the Phone software checked as it might have gone faulty.

remove the batteries from remote and try turning the tv on manually and see if it still does it. if it does then your tv probably has a bad part in it and your tv is turning off in fear of overheating, must be looked at with a local repair shop.

Power LED flashes orange 1 x 5 secs. = 1 of 3 fans stopped. TEMP LED flashes 1 x 5 secs, = Temperature error. Lamp LED flashes 1 x 5 secs. = lamp ballast error. (check lamp 1st.)
Hope this helps.

when i turn the power on , it goes off in 3 sec after displaying "f61"

might be a crooked flyback transformer, first check for shorted transistors around the transformer and components at the horizontal output stage..
