Question: I received this lamp 5-6 weeks ago. The picture is great, but now the tv is randemly turning off. Could it be defective? Thanks-
Document: I got the tv for free a couple of weeks ago. The picture was dark, but I got some blinds, thinking...... well then the picture went out. I called Samsung, they told me I needed a new lamp, and theirs was $129 plus shipping.
After installing lamp in my Samsung, which was a snap, picture was clear and bright. However, about 3 weeks later tv would start turning off after about thirty minutes of run time. Should have listened to all the other reviews and went with an actual Philips bulb. Lesson learned.
When I didn't hear from them, I sent another address which was gmail.I got a response back that said my e-mail address was censored. I then asked if they would send it by U.S. mail. They said they would do that and there's where we are now. I have had more trouble ordering this bulb through Amazon. I previously ordered it a couple of weeks ago and the one I received when I installed it in the tv blew up.
I was uncertain I wanted or needed to replace the bulb on my 61" Samsung DLP, but I could not be happier. I received it in a timely manner and WOW what a difference it makes! Thanks for giving me my TV back.
So far so good. The installation was easy and the picture on our tv have been revitalized. The only thing that is frustrating to me is that I paid for the insurance plan when I bought the tv 5 years ago assuming I would need a new bulb sooner rather than later. The price of the product was reasonable and it saved me a trip to the electronics store to look for a new tv. Overall, I would purchase the product again.
So far it's perfect. The picture on my tv is great and I couldn't ask for a better price. Thanks!
I purchased 2 lamps from another vendor and the first one died within 6 weeks. The second lamp died within 2 months. The lamp from this vendor is working great after six months. After my previous purchases this is a success.
Purchased this lamp about a month ago. The tv was still going on its original lamp from 2007 and was pretty dim and unwatchable. I bought this because it was made in the USA and was very cheap. It took all of about 5 minutes to switch out bulbs and voila! New TV! This bulb does seem to take a little bit longer to warm up but it has worked flawlessly so far!
This replacement lamp works great. It arrived a day earlier than expected in perfect condition. The picture on my television is great. I installed it about a month ago and have had zero issues.
So my rear projection TV finally went out after 5 years. I researched the symptoms and took a chance that it was the bulb that went out. I took my time and cleaned the TV off well as I went and it still only took 15 min. This was a direct replacement with housing and everything and instructions were readily available on how to do it online.Thanks for such a good product. Still going strong after almost 6 months.
Answer: May just be overheating like mine was. After I blew dust out of the fan and back compartment of tv, I taped blue switch that is inside lamp compartment cover down and haven't had any problems since. There is a you tube video showing this process
