Question about Sony Grand WEGA KDF-50WE655 50" Rear Projection HDTV

1 Answer

Blowing Bulbs in the 50WE655

I recently replaced the bulb, which blew almost instantly. I thought it was only the bulb and then learned of the ballast. The ballast was replaced by a tech and another bulb installed less than 20 days ago. Now, this bulb shot. I bought the bulbs and ballast on ebay, but my tech thinks it's the bulb (he said it may be a "B" line). It's made by LTI (Lighting Technologies Int.) in CA. I spoke to the company rep and she says some bulbs must be the OEM part. Now I don't know if it is the ballast or the bulb! Any help? would be appreciated.

    I've added an extra fan behind the unit and for 7 days (more than the last bulb) it is still bright and working. What is your response

    Thank you! Now 9 days and still going. I'll take your advise and contact Sony.

I installed higher amp bulbs,and my fuse blow out almost instantly,now my dashboard lights and Guage not working any more,any thoughts?


fuses are there to protect the circuit
putting in bulbs that required a bigger current draw that what the circuit was designed for will blow the bulbs
most bulb sockets will only fit the correct wattage bulbs so by fitting higher wattage bulbs there could have been a dead short
circuit boards are only very thing copper so the time taken if heating a fuse to fail point ( blowing the fuse) could have melted a section of the printed circuit causing the rest of your problems

My 01 grande Cherokee keeps blowing brake


the bulbs you mean, not the BRAKE FUSES?????

blows what.
if the lamps blow, they are the wrong lamps
or the alternator regulator has gone berserk and the line voltage , is over 15vdc.
my guess is bulbs.
and would be system over voltage.
i had one car in 1984 that the reg went nuts and blew out all bulbs in the, car at 2am. (and not a nice part of town either,,,,)
up upgraded that car to electronic reg. ,
like i do all my classic cars now.

buy a cheap 10 buck DMM volt meter at walfart.
and put it across battery terms, running and racing idle.
13.3 to 15vdc is legal range.

Bulbs keep blowing


You may be touching the bulb (ampule) and leaving a fingerprint on it which creats a hot spot and blows the bulbs up prematurely.

The light blew on my Beaumatic F60 extractor fan, thought the bulbs had gone so changed the bulbs, they lasted a couple of minutes before blowing again and then the fan wouldn't work also. I can't find a...


Look at the instruction/installation manual.
Are the bulbs 12volts or 120vac? If it is 12v there is a transformer that might be shorting to ground. If no transformer, the control panel or the control board has a short.

What causes headlights to keep blowing bulbs?I just replaced them and got about one hour of run time out of them.


When replacing a modern headlamp be sure not to touch the glass part of the bulb with your bare hands. The oil from your hands will ruin the bulb for some reason. Check to see if your lens assembly is letting water in this will blow the bulb instantly also.

I have a 2002 Kia Spectra ls, why does the headlight bulbs keep blowing? My husband checked the ground, said it was ok. He replaced only the low beam bulbs, to see if the problem was with the high beams,...


Check the socket to see if voltage is spiking over 13.5 volts with a voltmeter while revving engine . Charging could be bad.Look for bare wires around the assembly as well.
