My Sony KDF50E-2000, the projection light went out, i replaced it, it was working, then the replacement light went out too. Is this something with the TV or do I need to buy another light?

There are a few common causes for rapid bulb failure. If you touched the replacement bulb with your bare skin, oils on your skin will cause hot spots on the glass and can cause quick failure. Also, there are cooling fans that provide cooling for the bulb. If these are not working, bulb failure will occur.

My picture will not come on. The display lights on the front are blinking in rotation. i pulled the lamp out and it appears to have burned out as there are glass pieces inside the casing. How can I...

Replace the bulb to clear the error state.
If the cooling fan isn't working at this point, power the unit down, and you will at that point know whether the cooling fan was the issue or not.
If the fan is working, then the bulb probably just blew due to age.

Ok ok I am trying to find a cooling fan for the bulb but cant find one on line can someone help send me to a site that will have this bulb cooling fan? and how can i tell if the fan is the true issue

The part numbers for the (2) Lamp fans are: UX21521 (upper) and GS00506 (side). You can obtain these from 1-800-448-2244 at
Hitachi America, Ltd. Digital Media Division
900 Hitachi Way
Chula Vista, CA. 91914-3556

BUT, I do not think this is your concern. It is possible but I have not seen a fan on this Model go bad yet. So, give more information so the TV can be trouble shot better.

Godd Luck, Big Irish.

I have a KDF 42WE655..while watching tv, I heard a popping sound.

If the lamp is blowing that soon, the cooling fan is not working, or is plugged with dust. I have heard some people have a filter that needs changing or cleaning. Check your manual. The cooling fan is on the optical block and not easy to get to.
Probably a job for a tech.

Bulb went out

This maybe a McGuyver thing. Last thing you want to do is block the air flow to cool down your TV set. I would blow out all the dust, get a HEPA filter for house ventilation, get a computer cooling fan. Cut and put the filter in front of the fan, make the fan blow in to the TV vent in the back, that way it blows clean air in and keeps dirty air out. I hope that's one good idea.

42 inch LG Plasma TV - Lost picture

Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

Recentley my tv just turned off. I heard a buzzing sound which happened the 1st time my bulb went out. So I ordered a new one. When the new one was put in it worked for 5 minutes then turned off and...

This could be a couple of things. Look at the cooling fan and be sure that it can spin freely. If it is stuck, the buzzing could be the motor trying to spin the fan. Other than that, the ballast could be failing as well. This is the part that "fires" the lamp. Examine the fan first and let mw know what happens.
