I have a Sony KF42WE610 the bulb tends to blow out in 1-2 months . I think the fan is bad? The last time I replaced the bulb I noticed the plastic around where the bulb monuts into the cabinet was a little melted. I thought perhaps it was not getting enough air circulation as the TV is in a tight cabinet . I moved the top shelf up so the air could circulate but the bulb still blows out?

Because you have given absolutely no details I am forced to guess as to your situation. The big factors are, what type of bulb did you get, how often do drive and is your car new enough that the lights come on even during the day?
Super bright bulbs are nice but they tend to burn out faster than normal bulbs. They claim to be good for about a year. How Long Should Car Light Bulbs Last But for some reason, a lot of companies consider that the average car only gets used for 12,000 km per year. if you drive double that, your headlights may only last half as long. Is you headlights on all the time or do you do a lot of night driving, it all affects how long the lights last.

Your lucky it lasted 1 month. The population thinks they are receiving inexpensive items from China. Instead they are cheap useless rubbish. You will find that anything from Asia costs half as much and only lasts 1 tenth of the time. DO THE MATHS PEOPLE WE ARE BEING RIPPED OFF. While Asia is getting rich.
check the ballast leads which enter the rear of the lamp compartmnent they can tend to get pushed in slightly and prevent a good connection to the lamp. If the connections all look good then the lamp driver (ballast) is most likely defective
Hi,Osram lamps average around 3000-4000 hrs.Normally 1 -1 1/2 yr.I do think the lamp went out.The ballast is a possibility,when it's going bad it will make clicking noises or attempts to light the bulb.I recommend to get the Original Philips lamp for they average 6000-8000 hrs 3-4 yrs.
I would suggest getting an electrician to check the current running through the wiring. I had installed a similar fan in my grandmother's house a couple of years ago and had the same problem. After a couple of months of constantly changing bulbs, I brought in an electrician to check the current and found that there was a short in the wire which kept causing just enough of a current surge to blow the bulbs.
There are several reasons for short lamp life. Inadequate ventilation or clogged cooling fans, a bad lamp driver or lamp ballast (they are the same) and the use of non-original Sony lamps, as the aftermarket replacements are known problem causers. Remember too that the number of times the lamp is turned on and off is a BIG factor in how long the lamp will last.
"The only things I know of that cause bulbs to blow are, defective
product, has been used its average life span, over voltage, heat and
The implication is that this has happened repeatedly so defective product is unlikely.
If it had lasted its normal life span you would not be asking the question.
Over voltage is out because the switch is off.
Heat is out because the the bulb is not burning when it blows.
That leaves vibration. Some types of candelabrum bulbs seem to quite sensitive.
What's above the ceiling The tink you hear is the filament breaking
This most often happens when the bulb is hot. Very unusual to break
when cold unless dropped or mistreated.
Don't see a fire hazard because switch is off."
