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.

You have something on the lens. If the lens was producing excessive heat it could be the melting around the lens itself, or it could be grease from your finger that was clear until it got hot enough to cook onto the glass. Either way, remove and clean the bulb lens (the one on the bulb you change out when the bulb blows) and then re-clean the focus lens on the front of the projector (the one you turn to focus).

If this doesn't clear it up, look for damage on the focus lens or the bulb lens.

Good sound, no picture, green standy light flashing


Replace the lamp-mine just went out also and sony told that I just need to replace the lamp---after a while the lamp indicator light will turn on red if and blink if this is your problem....also note to make sure it is your lamp unplug your tv from the wall or surge protector for atleast a minute or 2 and then replug it back in and see if the lamp light blinks red? If it doesn't then you got something else wrong. I hope this helps...if you need further assistance contact sony online via chat at sony.com and they'll help you fix the problem in no time. Take care

If my lamp is out, would sound be present?


Check lamp cooling fan for dust blockage. It is located inside the back cover (10 screws) and is in a horizontal position above the lamp from the rear side. This is an air intake fan. The cooling fan you can see on the back panel is the exhaust fan that sucks out the hot air. A clue is hot or melt marks around the lamp housing.

If the lamp cooling fan is blocked you'll get red flashing diagnostics light flashing. It's trying to say clean me so I can keep the new lamp cool. Sony is silent on this in it's manuals. I'm guessing they don't care because is causes lot's of parts business!

I learned all this after replacement lamp burnt out after 1 week. My lamp cooling intake fan was found blocked and wasn't spinning. I saw the exhaust fan working and thought all was ok, not even knowing there were more fans. Some models even have another fan inside the optics blocker. I didn't take mine apart that far.

Sony KF-50WE610 flahing red light (6 blinks)


Jeff, did you look at the Sony web site? They had a problem with 9 different TV models that were from 2003 and 2004, KF-42WE610, KF-50WE610, KF-60WE610 and 6 other models.
This is what it states: It haas come to our attention that a limited number of Grand WEGA rear projection TV's may exhibit warping to the lamp access door. In rare cases, some additional components may also become damaged as a result. and so on........
You probably have some components melted on the inside around the lamp. I have a 42 inch and I just replaced the lamp at Christmas and the door was melted shut. This is the second lamp that I have replaced, the door was starting to melt the first time. They never sent me anything about this problem, and as of today I am still trying to work something out with them. The repair shop who has it told me that it can't be repaired. The parts that are melted are not in stock and they don't make them anymore. They are supposed to get back with me and make me some kind of offer.
They will only fix this problem through March 31, 2009.

    Our lamp does not turn off


    This is a defect that Sony has "kind of" recognized with an extended warranty, till 2010. I consider it a fire hazard and feel strongly that Sony is underestimating it. They are also NOT fully supporting the warranty and seek to charge me for repairing the problem, at the minimum an "installation fee" for the new bulb. BS. I am writing to the CPSC and Consumers, and taking them to court. Good luck!

    KF 42WE610 turns on for two seconds, then goes black


    no, had the same problem. Its the lamp ballast also called the lamp power block. It supplies power to the lamp, any how some repair shop wanted $450 to fix it, so i ordered the part from sony, part #146879816 ($116.25), trust me this is the part I double checked with many different places. Any how fixed it my self took about 15 minutes, just take the back cover off and the part is right there just kind of follow the screws and the 3 wires, super easy job, I suggest you replace the bulb at the same time, dont by a cheap bulb just get it from sony
