HDTV TLC: Projection Lamp Failure and Replacement

[Richard]

If you suspect lamp failure the first step is to check your owner's manual, which will tell you how to read/interpret the indicator lights on the front of your TV or on your front projector. If you do not have the owners manual, odds are very high you can find it on the internet and download it. Manufacturers often times provide these manuals on their web sites.

I have a 2004 Toshiba 52HMX84.
I have replaced one lamp.
My warning lights started to flash and the video would go out, so I ordered a new lamp.
Received the new lamp, installed same, would not work. I called Toshiba and was sent a new lamp. I did this four times and the "new" lamps would not work.
I tried to ask Toshiba what the problem was, but received no help.
My "old" lamp is still working and I don't know what I will do if it fails.
I believe Toshiba changed something in 2005 when they had lamp problems,but can get no information from them.
If anyone can help me I would be thankful.

Hi Cater,

Diagnosis starts with verification...

The model number came from the back of the display?

What is the part number of the lamp you are ordering?

Please provide a phone number, URL, and or source for where you purchased these lamp cartridges.

You are getting a lamp cartridge rather than a bare lamp?

Richard,
I did not state this is a DLP TV.

To answer your questions:

The model number is correct from back of display ( I also have my original owners manual).

The part number of the lamp was given to me by Toshiba based on my model numberIt is TB25-LMP, I also have the installation instructions from Toshiba listing my model number as correct for that lamp.

My first lamp came from DLP Lamps who told me to call Toshiba when the first lamp did not work ( 1-888-501-9956). I received four more lamps from the Toshiba company ( I have names and times of who I spoke to).

I received a lamp cartridge each time ( I have replaced a lamp on a previous occasion - it is the lamp that works now). I was told all kinds of things to do from Toshiba, includinf tapping on the lamp (aladin?), etc.

Per the service manual the lamp is reference SK02, Toshiba part # 23587201 with an internal number of SHP66. Per a distributor I came up with 23311083A which is the new part # for the lamp. TB25-LMP also crosses over to 23311083A at the distributor but I have never seen such a Toshiba part # before. Toshiba part numbers are 8 numbers and optional character at the end in the service manuals.

My first lamp came from DLP Lamps who told me to call Toshiba when the first lamp did not work ( 1-888-501-9956).

Dunno a thing about them. I looked them up along with your lamp and their price is $168 yet the one from the distributor is $199. Hmm...?

They also state:

Original Lamp Manufactured by Toshiba
In a Toshiba Box

Yet the price is profoundly low - way too low for my cost on this item. Lamp cartridges have little margin in them... hence the bare lamp market

I received four more lamps from the Toshiba company ( I have names and times of who I spoke to).

Gotta phone number?

The best suggestion is call (800) 432-8542 and order 23311083A. It will be an OEM lamp cartridge. Please let us know how that works out.

I investigated this further at the Toshiba consumer site. Using the site search function your TB25-LMP cartridge came up for $218.69. I clicked on lamps showing all six available and noted while all ix have this consumer part numbering scheme, four of them gives the item number which is the Toshiba part number I would work with.

On this page I was able to find Toshiba parts distributors.

I started a post on my Toshiba dlp lamp replacement failure several months ago.I received four lamps from Toshiba - none of which would work. I would think this qualifys for OEM replacement?
Something changed with Toshiba after thier 2005/06 or whenevr recall and they will not share this with me?

Cater,

Why did you add this post to a Panasonic thread that was unrelated? I am trying to help and you never responded to my last suggestion...

The best suggestion is call (800) 432-8542 and order 23311083A. It will be an OEM lamp cartridge. Please let us know how that works out.

Did you try another lamp cartridge from a verified Toshiba source as recommended?

[cater]

Richard,
I am sorry for posting to the Panasonic thread. It seemed to fit my concern that the "new" lamps are not matched to the ballast.

I did not reply to your last suggestion because I have in my posession two lamps wiyh the number 23311083A direct from Toshiba that do not work. I stated several times that I spoke to Toshiba people and receved the lamp(s) from them.

[Richard]

It seemed to fit my concern that the "new" lamps are not matched to the ballast.

It had nothing to do with that. He is trying to circumvent paying the Panasonic price for a lamp cartridge by finding a bare lamp to install himself. Problem is he can't get the OEM bare lamp and is using substitutes. He is reaping what he is sowing...

There is no problem obtaining the OEM bare lamp in the form of a lamp cartridge only from the manufacturer (beyond the problem that you will pay more). Your concern that the manufacturer has created a mis-match by substituting the bare lamp inside the lamp cartridge is false.

The only manufacturer to have created such a problem is Samsung. On one model year they decided to change the ballast/lamp circuit mid-production and you must order the lamp based on the lamp code located on the back - not the model number.

You never gave me that phone number and the next step in helping you was for me to call that phone number and verify/confirm what you believe to be true.
