DLP lamp only replacement procedure and experiance - Page 2

post #31 of 73
Thank you for this excellent thread, VideoBruce!

The Tophinator, thanks for the detailed instructions and helpful pictures on replacing the lamp in your HL61A650. I have the HL56A650 which should be the same. What model # was the lamp you used?

Thanks The Tophinator! After posting that it dawned on me that I should check the manual or the sticker on the back of the DLP...

Hi guys, my Mits WD-62628 gave me the red lamp of death (bulb done) so I ordered a new one from River Valley. Installed it (no housing) but the tv is still giving me the red lamp light (after about 1 min of apparently trying to fire up with no luck).
Any suggestions?
Thanks

Probable bad ballast unless it is a defective lamp. Give them a call.

Thanks for starting this thread Bruce. Eventually I will need to change a bulb and I will refer back to this thread.

Haven't had a chance to get back about my purchase of a Mits DLP lamp assy from MCM Electronics until now...

I received it on the 5th, but I think if I had ordered it a day sooner I would've had it by the July 4th weekend. No matter. The package was double-boxed with the inner box being labeled with all the normal Phillips text and such. The outer box didn't have anything in the way of packing material underneath the Phillips box, and the lamp assy, while held fairly well in place, wasn't put in any kind of plastic bag before it was boxed up and shipped. This type of lack of protection for the assembly is annoying to me, and when I looked closely at the lamp lens under bright sunlight, I clearly saw dust on it. Probably not a big deal, but I've had bad experiences in the past with some of these smallish online retailers so I get a bit perturbed when I don't see attention to detail such as this.

Anyway, I swapped it into my TV (yes, it has the larger mesh screen), powered it on and all was well. The only other difference between the factory housing and this one is the fastening screws aren't the large kind with knurled edges, so you're forced to use a screwdriver to tighten the assy into the TV. I'm still seeing the Halo effect so yes, a light engine cleaning is still on the to-do list. But the goal of having an extra lamp assembly on hand has been achieved. All is well... I am happy... thank you please drive through.

Not necessarily sticking up for MCM, but they are not a "smallish online retailer". Their prices (when not on sale) are not the best, but they do have a wide selection. There are better places, but I would give them at least three stars (out of five).

I'm a little confused about the packaging. You said the lamp itself was not packaged correctly.

You would have to take that up with Phillips. MCM (or anyone else) doesn't 'box' items inside of manufactures boxes. As far as placing the item(s) in a outer shipping box with no packaging at the bottom, that unfortunately is a common practice. I see that all the time. very little packing on the bottom, Six inches above. What do you expect for paying someone just $7. per hour?

Those two large, screened openings only use convection currents. There is no fan pushing air through those. They were not dusty.
Note with the before shot, if you notice the very corner of the screen you will see the dust buildup that covered the whole screen before I vacuumed it.

If you take a closer look at the photo of the lamp mounted in the housing (2nd previous post), you will see a 'arch' to the front of the reflector on each side of the lamp assembly. Air is forced across this area in front of the actual 'bulb' within the lamp assembly. River insists this was a mistake, calling it "factory design flaw".

I have removed this screen,but am a little worried about dust build up on the bulb element and the possible fire hazard.

Interesting point.
I doubt that would be a issue as the air flow wouldn't allow that to happen. I also doubt if it was, that supplier would of recommended removing the screen in the first place.

I guess we just have to see what happens.

Bump, for all that don't do a search first.

I have a WD-73833 tv and need to replace the bulb, I was reading on some of the post that I may need to "file" down some of the bare bulbs for it to fit in the housing. What needs to be filed down? Or do I not need to file down? The bulb I was going to order is at the following link

bulbsoutlet.com/shop-by-brand/mitsubishi/mitsubishi-915p061010-bare-lamp.htm

Its a Mitsubishi 915P061010 if I do need to file can some one point me to a tutorial. I tried searching but didnt have much luck.

Thanks In advance.

Why would you want to pay $114 for a lamp you can get for $88? Did you check out my 1st post?
Your link is here;

post #45 of 73
Ok, why does everyone have to be an ******* the sec they think someone didn't read the holy bible of info that they posted and must be obeyed by all? If you would go back and check the link like I did after reading through your entire post twice you would see that the bare bulb is not currently listed on the river valley site anymore, they only have the bulb with housing at this time. I just had a simple question and wanted to get some clarity on it. You said in you posted the clips were harder to put on the new bulb cause the housing was a lil different I was wondering if that is because the bulb needs filing down like some of the other post state. Your guide is much appreciated but some of the info is not accurate at this time. If you have anymore incite on the filing situation I would love to have some more clarification. I will try calling the seller today that I listed to try and get more info as well.

Thanks

Just bought a replacement for my Mits 73737, installed it to make sure it works, just bought it as a backup. Piece of cake, $99 from Mits complete with housing. After over 2000 hrs I saw no difference so I put my old one back in. It won't work without the back cover installed.

Apparently, Mits dropped the price on replacement lamp assemblies. (it's about time ).

I just replaced my lamp on my 60735 5 days ago. All was fine until this morning. Turned the tv on and in 3 minutes the thing shut down. Amber flashing status light. OK says to check lamp door. Open door remove lamp, check lamp, (looks fine) replace lamp and door. Turn tv on and starts up with sound no picture. TV turns off in 1 minute, tried again, same thing. Anyone have any idea or suggestions on what the issue might be until I can get in touch with service?
Thanks

Do a search for 'ballast' & 'lamp sensor'.

My Samsung did the same thing last month which I thought was the sensor like the above post but I changed the bilb and that fixed it.

Thread bump.

The lamp in my WD-65833 is becoming too dim to be acceptable anymore.

I was going to order the complete lamp assembly from River Valley, but at checkout I was given the option of the standard Osram lamp or for $15 more a Phillips lamp

To those who've tried both, is there any advantage to one over the other?

Mitsubishi has dropped the price of most/all of their lamps to $99 direct from Mits.
It would make sense to deal with them directly, instead of elsewhere. At least if some other problem arises, they can't blame the choice of another type lamp.
post #53 of 73
It's most of the lamps, for some reason mine WD-65833 is still $249.00. So I don't feel so bad about the lamp that I just order from River Valley

FWIW, I have seen lamps for 'RCA' RPTV's for around $450.

A warning to all other 65833 owners ordering lamps from River Valley.

I ordered the lamp and assembly from River Valley (Part #915P061010), but the assembly didn't fit into the cavity.

I had to use the original assembly and swap the lamps out.

Which also took a bit of work, as I had to file the fittings in the assembly down in order for the new lamp to fit snug into the old assembly.

Wow, i better get a replacement on order, mine stays on all the time since Christmas last year. 7851 hrs. I get no change in picture between bright and brilliant anymore. Hope new lamp arrives in time for BCS game. I figured these lamps were similar to a light bulb and what kills those the most is on and off cycles, or the heating cooling process.

Gotta love Ebay, new lamp and 3d start kit $418 shipped.
Almost bought the 3d kit off Amazon 2 months ago for $399 alone.

Depending on how you adjust the set, there is little difference. Why they bothered with a 3rd setting is beyond me.

You are correct.

Just put mine in and it fit perfect. My picture looks great, even my wife could tell the difference. If I were you I would call them up and complain, as they must have sent the wrong or a bad item.

Bumped for any of the owners of older DLP's.

Also for general reference, here is a 'Archived' Mits thread;
