Sony bravia works on ups/battery not mains :(

Guys here the problem: a month ago, there was a huge power surge and thick smoke came out of my sony bravia lcd...i turned it on after a while and it worked fine....i was surprised as to how it could work..i asked a support guy n he told something about some power surge liquid inside it and blah blah..i honestly didnt understand him...he told theres no problem and it worked fine for a month n now yesterday, the picture started scrambling...it was like...every 2-5 seconds,it would say no signal..picture would come for a few seconds and again it would say no signal...after a while ,the tv would turn off(not standby,just off).... and another peculiar part is,we use inverter/ups at home..when its connected to just ups, works fine!! when its on mains,the problem occurs.. can anyone tell what the prob could be? the tech guy on phone told cud be a capacitor issue but im worried whether its some major problem.. pls tell : 1. what is that "power surge liquid " the tech guy was teliing about ?or what do u think really happend when smoke came? how did it still run?? 2.what could be the current problem? UPDATE : i tried turning it on a few mins back,now it wont turn on at all! it used to work fine on ups..now even the red light doesnt come...i can see its drawing power as i can feel its load on ups...HELP :(

Sure sounds like the power supply board received an insult that allowed a different voltage to work for a while . UPS will regulate top 120 volt whereas mains may be higher or lower . You may be able to change bad capacitors or just buy the power board between 80 to 200 dollars .
If it was connected to UPS during surge it should have been protected...make sure you are connected to 'battery' side as a lot of UPS have a 'surge only' side that will not stop a rapid on/off power insult .

If TV does not remain in standby and turns on itself then power switch on top of it could be defective and power supply board is also suspected. Take off its back cover and unplug top switch connector just to confirm is that cause of On-Off its own. If problem still exist then power supply board has problem and will be replaced. Let me know the results to move forward.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

Power Outage Problems Sony Bravia 32" LCD TV


try cycling the power (unplug 2 minutes) and plug in and wait 30 seconds and turn back on. if this doesn't work, could have been a surge, your protector should have saved it, but could have been through cable or something. surge protectors will guarantee no damage for several years, check with the manufacturer maybe they'll cover the repair.

Sound doesn't work on television Worked fine yesterday but it isn't working today. I know the power went out briefly(few seconds) today.


Check a different input and all the connections to the TV to see if they are secure. After doing so and you still are getting no audio from all inputs then it means the audio processor failed. It was most likely caused by a power surge when the power went back on. This is fixed by replacing the main board. It is usually called a BU or AU board on Sony LCDs. Can be prevented in the future with a good surge protector or clean power surge filter.

Please make sure that the connections are secure.


If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

Please try connecting the TV to a different wall outlet and check if that helps.

Sony Bravia LCD TV is tripping the fuse in the house


These things draw a huge surge current when turned on. What size fuse are you blowing? These things can surge 10-12 amps on turn-on. What about a fuse with a reset button. They will take alittle more surge before they go. Don't matter about the insignia working before because the cheaper sets tend to stay powered up more when off....thus not surging on from a dead start. Could you try a different plug on a different circuit/fuse? and see if that makes a difference. If you have a 15 amp fuse, then your pretty close with other stuff plugged in. What size is your service? Do you still have an original 60 amp box with screw in fuses? Is it an old house?
