Nice to see occasional new posts and I hope this old thread has been helpful! It certainly has been helpful to me over the years.

My A650 was purchased in May 2008 and currently is still our main HDTV. It has approximately 20,000 hours with no repairs yet, and is still on the original lamp. The picture is a bit darker now but still very pleasing since we can keep the lights low in our media room in the basement.

I keep thinking it's time to sell it for a couple hundred now before it develops a real problem but keep putting that off. I doubt it will last much longer but I've more than gotten my money's worth out of it and who knows, there's a chance it might last a couple more years. I have no major complaints with the picture so it seem wise to use it until it breaks then buy something new. I don't know if I'd gamble on a new lamp or just call it quits even if the lamp goes.

Anyway, I hope there's a lot of life left in these old DLPs for everybody here but sadly, when they start going bad be careful not to allow them to become a money pit!

Good luck, all!
You are supposed to change the lamp, and when you do, it'll be like having a new TV.

Lightbulb 2008 61" hl61a650

I have had this TV since it was new, when I purchased it in 2008. Since then I have had to replace the bulb and ballast, at the same time. This replacement was about 2 years ago, and I have had no problems until recently. I am getting frozen pixels that are constantly white, so far I am up to ten pixels, all located in the lower right corner of the display. Weird thing is that new pixels only become frozen while viewing an HDMI source, and never anything from the coaxial input after about a week, but put on the Xbox or Blu-Ray player and new pixels show up within the hour.


From what I have read it looks like it might be time to replace the DLP chip in the TV. Has anyone had any experience with this, and is it user replaceable?


I have a good understanding of electronics and experience wit replacing components (voltage regulators, resistors, diodes, caps, etc.) on PCB's, if that makes any difference.


You guys are awesome for putting together this thread, I have been a subscriber to it for a few years now.


Anyway, thanks for the help in advance!

True, but I just made the decision to buy a new TV instead!


It appears Samsung and LG have joined Panasonic and Pioneer, ending their plasma production so it's now or never to buy a new plasma panel while they're available. LCD just doesn't do it for me so I jumped on a Samsung PN64H5000 which should be delivered January 8th.


The A650 will slide into a secondary role and probably get passed on in the extended family. No doubt if it stays in the family it will get a new lamp. Right now in a controlled light environment (basement media room) it's still bright enough. I am amazed how little trouble this Samsung has been and hope the new Samsung plasma has a similar long, trouble-free life. I am looking forward to the larger 64" screen and deep black levels!


Ironic having both DLP and PDP, the perfect way to dodge the mainstream move toward large screen LCD!

Personally, I am holding out for OLED to come down in price and for more flat screen models to be available! Not a huge fan of the curved screens.

I also expect my next big TV will be OLED.

Good luck with your A650 repair!

Anyone have their dlp make a popping noise/fizzle , slight burning smell, yet the TV is still working? Happened last night on my hl72a650 after I turned the TV off, before the fan turned itself off. I fully expected it wouldn't turn back on, yet so far it's working fine. Pulled the lamp and it seems okay. Obviously something is going to fail soon. Should I continue to run it until it dies? Anyone have a link that shows how to replace the main power supply or ballast? If it's either of those, I'll attempt a repair. Bad color wheel will mean time for a new tv.

I have never had this issue, but it could be your bulb or ballast going bad. I would try cleaning it out also.


When is the last time you replaced the bulb? Does it only make the sound after you turn the TV off?

Sorry for the multi-post,


I replaced my ballast not too long ago. It a simple and strait forward job, just some screws and a few wires if I recall correctly. You might need to take the whole back panel off too. Since then the only issue I have had is my DLP chip going bad, which I have yet to replace.

Happened again today. Loud pop, slight smell. TV power cycles, then turns back on fine. Will pull the back cover off and check the power supply and ballast. I suspect one of them is on their way to die.

Definitely sounds like electrical arcing, hopefully a good cleaning inside will help, at least to find the the problem. Good luck!

If the issue is with the ballast, how do I change it? Do I have to pull out the entire light engine assembly?
