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

1 Answer

Sony kdf 50we655

I replaced the bulb but the picture has lighter areas on the screen, makes the picture bluer. I got another replacement bulb and the same problem is there. I don't think it is the Tv because the light patterns change along with intensity. Could it be that the bulb is just not situated the housing correctly?

Heat and dust are two major problems with this type of set.These set can get very dusty inside the optics and cause this type of discoloration .Heat can cause deteriation on optics and or optics cabinet parts .It is possible to clean the optics block for dust issues only but unless you know what your doing and know what areas not to touch inside optics block .Otherwise the block would have to be replaced..

Bulb replacement


Ok, you can buy the bulb separately and it will save you money. I will have to warn that , installing this bare bulb will be tricky and you can not touch this bulb with your bare hands. it will damage it. Other than that, it is possible to purchase the bare bulb alone. i will post a link to your replacement bulb without the housing below.

Please rate and have a great weekend:)
