The Official HP Pavilion 1080P DLP Owner's Thread - Page 361

Assuming it's the primary bearing of the color wheel, it's really hard to say. IIRC, the bearing is similar to the bearings used in hard drives before fluid dynamic bearings became popular. With those old hard drives, sometimes a noisy hard drive would last a long time. I think there is a decent change that it won't get worse quickly, and you might get another year out of the set.

Sounds good for me too, maybe Fry's will have it on sale. I miss my HP dlp...

$1500 for an 82" DLP? I had no idea. My 6580 is still going strong (knock on wood), but that might be a nice replacement when the time comes.

To think what I spent on my 50" Fujitsu plasma when I bought it almost 10 years ago (768p, DVI, no HDMI). Of course, it will probably outlast my 6580.

Hey Tigga, I have a dead light engine with a physically intact color wheel. If you feel like pulling your light engine and swapping out the color wheel, I can test mine to make sure it spins and send it to you. PM me if interested.

I have 2 HP bulbs for sale!

I kept 2 HP5880 bulbs on hand as spares and now since I do not have the TV I want to sell them.

$100 for the two bulbs. Bulbs come in the original boxes, however, they are both slightly used. I used them both for about 6 months to break them in.

Looking for some insight..

Have had a MD5820N (58' 720p) since 2006 that has been a great tv. About two years ago the bulb blew, replaced it with one from Electrified. About a year ago the color wheel inside the light engine shattered. Found a place that would refurbish the light engine including a new color wheel. Shipped that off, got it back, everything was good again. A few weeks ago I there was a noticeable dimming of the picture. No amount of adjustment to the settings would fix this, just wash the picture out if you jacked the brightness up. Also, going into the Advanced Picture settings, toggling the Brightness Boost on/off showed no change. I suspected the generic non-OEM bulb from Electrified was probably nearing the end of it's life, so I ordered another, which arrived today. Installed the bulb, same exact brightness and behavior.

Any thoughts? Possible it's something with the refurbished light engine? Something else?

Thanks in advance for any thoughts or suggestions.

Hi Coucher,

It is rare that I read a post from someone with a 720p model. HP must have sold a very small number of those sets. I think I saw one once at a Sam's Club.

A dim picture is almost always fixed with a new lamp. Since you tried that, I think the remaining possibilities would all be pretty expensive to address.

My first guess would be that the voltage regulator that feeds the lamp is not delivering adequate voltage. It sounds like the picture got dim very quickly, so I doubt that the problem is caused by dust accumulation anywhere along the light path. If the colors look good and the image looks good (other than being dim), the light engine is probably fine (other than, possibly, the lamp voltage regulator).

It's probably time to move on. Luckily, very nice TVs are pretty inexpensive these days.

-Dave

Dave,

Thanks for the direction on the voltage regulator. I may investigate this path a bit further. Even though noticeably more dim, the tv is in a dark room so it's still for the most part usable, just those dark scenes in tv shows are movies are a little bad.

Back when the color wheel shattered 2011 while awaiting the refurb on the light engine I had went ahead and picked up a 73" Mitsubishi DLP.

It's hard to let go of this HP though. The connections, features, picture, and overall design are still impressive. I actually often prefer watching it over the Mitsubishi.

I'll research the voltage idea a bit further. There's always a few guys here retiring them and parting them out, so maybe I can keep FrankenDLP going a bit longer.

Thanks again.

Definitely not the first or last to post about this, but does anyone have a color wheel available? I purchased one through eBay, but it arrived damaged and I'd rather not take that chance again. I'm having some red bleeding on the yellows and oranges going on as well as some intermittent red flashing all over. Any ideas would be more than welcome.

Hey everyone,

I also have a HP Pavilion MD5820n, the 58" 720p version. My color wheel has also been damaged (and maybe even the light tunnel too) and I'm looking for anyone who might be willing to send me that part out of their TV. I'm just a college student so I wouldn't be able to pay much but I figured I would try to fix it again because it was so much fun to have.

Hey guys! Been following you all for years, first time to post.

I have a HP MD6580N that has served me well since 2007. I was on my second bulb and I thought the TV was looking dim, so I took it to downtown Dallas to have a new lamp remounted on the module. Now my TV doesn't work (the blinking lights indicate lamp module problem). I am moving at the end of February and would like to get this TV out of the house so I don't have to move it. I'm taking the best offer. I believe it only needs a new lamp as everything was working flawlessly until it was replaced.

I'm in North Dallas and would prefer someone pick it up. Thanks!

Hi All,

I have a HP MD5880N DLP TV and recently the picture started to fade and the front panel light indicated that I needed to change the bulb. I bought (my second one so far) "Electrified L2114A / L7135A / L1736A / L1737A / L1798A / L2114A / L2114A-8001 Replacement Lamp with Housing for HP TVs" from Amazon. The product does not seem new, there were fingerprints and the bulb does not match with the original HP bulb I have. The reflector seems to be unclean and not smooth. The screws do not get tightened. They are different from the original housing I have. The product is made in china and way inferior than the original HP lamp. I contacted Amazon and they said they will gladly reimburse the full price once I return it. I also contacted Electrified and they said I need to return the bulb with housing to Amazon and may place another order with them (on Amazon site) so the bulb gets shipped directly from them.

1. Is there any way to purchase original HP bulb? That bulb I contacted HP and the person from Indian Call Center said I may be better off changing the TV. #@$%@#@!
2. Has anyone bought from Electrified and how was the quality of the bulb?
3. They have150 days warranty and I do not want to replace my TV yet as so far it is working fine.

Thanks.

I live just outside of atlanta and am looking for a bulb for my md6580n this will be the 2nd bulb since 2006 which isn't too bad. Tv tries to come on right now and blue light flashes fans come on and black screen and it sounds like it wants to work but then shuts itself down. After a ton of troubleshooting and no warning lights to speak of i'm thinking it's just the bulb even though it looked fine when i looked at it. Anyone have one for sale? me@lesliehaugen.com

^^^ You might get more info if you searched this thread for all of the "bulb replacement" posts.

Bull_dozer and LeslieK,
I recently got the same bulb from Amazon for my md6580. Fortunately, mine was a better quality (without the prints and with convincing, the screws did go in). Third bulb since I bought the tv new in 2006, not bad in my opinion considering how many hours my kids have put on the tv. Unfortunately, this time I started getting colored spots in various places at various times, I decided to finally upgrade to 3D. Got a great deal on a Sharp PRO-70X5FD that I just could not pass up.

I loved my md6580 and it has given many years of faithful, wonderful viewing pleasure. Wish HP would have stayed in the game, but now I have an upgraded, bigger picture and 3D in less the space of the old. Lovin it.

Someone need an L2114A bulb? I've got three genuine HP bulbs brand new in box, and a used bulb in good working condition. Also have two original HP remote controls for the TV available. Make me an offer. Buy one of the new bulbs and I'll give you the used one, or one of the remotes...your choice.

I too really loved my HP md6580. I had never seen another HDTV with as good a picture. Until I got my Panasonic P65VT50 plasma set a few months ago. It's got a better picture.

-Dan

It's been a couple months since I posted, but I'm still looking for a color wheel for my HP Pavilion MD5820n, the 58" 720p TV. If anyone has a dead TV lying around and could sell me theirs I'd be extremely grateful!

Just the color wheel? I have a light engine that has been sitting in my garage since last summer. I'll see if I can get at the color wheel and let you know.

Hi kwarner,

Yep, I'm looking for a color wheel, one of the colored panes came off and shattered inside, it was impressive how strong the vibrations were from it being out of balance. It shook the entire floor of my apartment building and scared a few people who thought it was an earthquake!
Also, I realized I've been writing the wrong model, I actually have a MD5820n.

Here are some pictures of the serial number and metal casing: In the last picture you can see inside the metal case where the color wheel itself is. Mine is broken and missing a pane.


Does your color wheel have the same serial number?
Edited by RKinser - 4/28/13 at 8:16pm

I'm interested if you still have the lamps, I'll take the new lamp/used lamp deal.

FYI: I ordered a bulb from Electrified on Amazon as well - it arrived looking perfect, but was so dark I could barely see people in scenes that weren't lit brightly. Returning to to Amazon for a refund.

Here is my color wheel. The serial number is obviously different. Don't know if there were any variations in part numbers.


Send me a private message if you are interested. I'm not looking for much.

Hi, all,

I'm new here and don't like to barge in on a thread without a post count, but I just came into possession of one of these beasts from a friend that gave it to me for free.

I hear it starting up, the power light flashes, the main board and the ballast clicks, but no picture, and after about a minute or two, the lamp light is steady on. I can't find what this means. Bad ballast? Bad LVPS? Bad bulb (I was told the bulb was just replaced).

This TV did have a heat sensor issue and has the wires to the sensor spliced together, and it still has power, which there wouldn't be without the spice working.

Please advise. If possible , is something parting their telly for a ballast (maybe a whole LVPS? and a good bulb.

Thanks,

Vincent

Hey Vincent,

Where are you located?

I've got a whole MD6580n that is in Bristol RI if you want to pick it up for free.

please let me know,

Terry

Terry,

Thank you! I'm just in Central NH and I have a station wagon! I'll PM you!

I've been browsing through this thread and everyone here seems super. I'm excited to start reviving my beast!

edit: double post. Oops!

Thanks Kwarner but I'm afraid it probably won't work =/ Thank you for trying though!

Do you also have a md6580n? If you've got a different version then parts aren't interchangeable and it won't work.

Yes, I do. It takes up an immense amount of floor space, so I'm eager to fix it get it onto my TV stand

It finnaly happened I had 7+yrs of great viewing but I have now got my first serious prolem with my 65inch beauty, Sunday I whatched tv for about a hour with no problems, turned the set off returned 9 hrs later and opon trying to turn the set back on Nothing, It does not even try. Abosolutly dead the front access dooor light is even out.. I have checked door swithch, tried switching bulbs( 3 different) blowing out dust. pluging directly into wall, letting it sit over-night(when I did this the green light on the PowerSupply came on till I pressed the on button then the front blue flicked for a nanosecond then the green light went out and dead again) any thoughts on a plan of attack would be appreiciated.... can I jumper the interlock and/or thermal to test them (are they NO or NC respectfully) thanks for your time.
