Sir check the lamp of your projection if already damage, if damage replace the lamp and reset also the lamp hour meter. Remove the screws to open the panel labeled "lamp" on the back of the Sony TV. Remove the screws that hold the lamp in place inside the TV. Pull the lamp out. Let me know what is your observation to the lamp so I can guide you. Good day and best regards.
Hi, Sony KDF-50E3000 is LCD Rear Projection tv that has one lamp as back light source and optical unit (light engine) generates image that projects on front screen of tv, it is similar to multimedia projector technolog. Lamp part number is F93089000 XL-2500 utilized in this model. Thanks.
Hi it sounds like it could be an issue with board that powers the lamp ,it's called the ballast.When you put a new lamp in the ballast has to provide more power ,when it starts to go weak it will not light up.Sometimes you can put your old lamp in and will work fine.Try partstore.com they might have it right there.Hvae a blessed one!
Light Engine and Optics Block is same thing, main part of DLP TV and multimedia projector to produce and project image on front screen. Few manufacturer call it light engine and some says it optics block.
I had the same problem with my 4 yr old Sony KDF60WF655 rear projection set, and I was fortunate to buy a 4 year extended warranty - because it was the $1300. (not incl labor), Optic Block that was replaced to fix the problem. That part contains all new LCDs, & Lens & some electronics. I had already got a new bulb (under warranty) a few weeks earlier, that I had not yet installed so the service guy did replace that as well. (This happened 3 weeks before my warranty ended)
He told me that he replaces hundreds of Sony Optic Blocks every year and that many Sony Rear Projection sets have FACTORY extended warranties because of some known problems with the blue LCD panels.
The tech checked my Service Codes & showed me the TV had been running for 10051 hours in about 4 years - on the Original bulb! He was quite surprised because he said the bulbs usually last about 5000 - 7000 hours. He also said it's good to replace them BEFORE they go bad, because they can sometimes burn out the amplifier that powers the bulb, (which is a seperate piece that attaches to the outside of the Optic Block). My TV is like new now.
