Lamp cover melting

I am replacing the bulb in my Sony KDF-42WE655 and happen to notice that the cover for the lamp in melted. No signs of burning, smoking, smoldering, but definitely some heat issues.

Any ideas why this is?

Open the back case (about 10 screws) and clean the lamp cooling fan. This is NOT the one you can see from the outside. It is located in a horizontal position above the lamp area from the rear. A DRY toothbrush can be used to brush out the dust. Keep a vacuum nozzle next to it while cleaning so the dust does not go inside. Some say to use compressed air to blow out the dust, but vacuuming it keeps better control and can prevent unwanted dust from moving down into the optics.

I learned this the hard way when replacement lamp burnt out in one week. I thought the cooling fan that you can see from the outside (it actually is the exhaust fan) was the only fan. The lamp cooling fan sucks in cool air and puts it right down onto the lamp.

Test the fans by turning on unit without lamp installed (the fans will power on for a short period of time and you can see them function to verify airflow). Clean this fan once a year as the dust will be back.

Its a warranty issue that Sony is aware of. They are replacing it and any other needed repairs until March 2010. Here is a link to the Sony site for more information.

I have a sony wega kdf-42we655 that keeps blacking out and loosing sound and comes on a few minutes later. the stand by light seems to flash around 38 times during the process. please assist

I believe you need the Lamp to be replaced. It is a very common symptom. Call Sony at 1800-222-SONY and they can send you one. I think it will run around 185.00 to 200.00.
I recommend to use only a Sony Lamp and not a After- Market Lamp because they have been known to be unreliable and not rated properly causing melting issues around Lamp area.
I hope this helps,

How do I replace the Projection Bulb on a Sony KDF-E55A20 and what where do I get the replacement bulb the cheapest....I have pulled the module...

It is my recommendation that you replace it with a Sony Lamp Assy. Do not go cheap buying a generic or just the lamp only. They have been known to be unreliable and the wattage to be wrong causing the surrounding plastic to melt. Sony will not be responsible for this if it happens. If you have pulled the Lamp Assy. out, just put the new Lamp Assy
in it's place. Be sure to remount the lamp cover properly. Remount the outer cover and you are good to go.
You can contact Sony at 1800-222-SONY
for the lamp.
Hope this helps,
