46H84 Shorting out/No replacement bulbs available?

The green CRT bulb on my 46H84 is shorting out and my repairman said the parts are not available. Is this true? If not true, where can I buy them?

    The part numbers for the 46H84 Toshiba given by Rylee Smith turned out to be wrong. I needed a CRT bulb, not a DLP Lamp

    Correct part no. should be 23078430.

I have Zenith rear projection TV Model IQC60H95W.The blue tube does not work. The red and green project. Is this a bulb or tube and are they available to purchase? The TV was made in 2001


This is a CRT(cathode ray tube) not a bulb. A Bulb is totally different. If you replace one Tube, you need to replace all 3 or the colors will never match properly. However, This model no longer has parts available. Even if they were, the cost would be close to $1000 in parts. I would not recommend repairing this TV.

How to replace procector lamp in model 46h84 toshiba


Projection TV sets have three tubes - red - blue - green and they don't fail often...they are located inside the tv DLP TV sets use a single bulb and a clot wheel to make the three colors display...DLP bulbs do fail about every two years and will need o be replaced. Replacements can be found at www.TvRepairKits.com and its located behind a small door on the rear of the tv.

I have a Toshiba 46H84 with a now defective Green bulb or tube. TV shop said government regulations won't allow them to fix it. Any possible fix?


I would be looking for a different shop and send them the bill.
If all fails go on ebay and get a new bulb and find someone who can replace it.
I wouldn't suggest you do it yourself because of the voltage these televisions put out.

You can find replacement parts for this model from the following Sony OEM parts distributor. Here's the links to order the original Sony blue CRT, green CRT, and red CRT (the 3 "light bulbs") for this model from that major parts distributor if needed:

Coolant leaked from the green bulb


Yes, the diagnosis was correct. Some models of Mitsubishi as well as a few other manufacturers have had issues with this. The cost to replace circuit board damaged by the coolant (ethylene glycol) along with the affected CRT is prohibitive. Check with Mitsubishi. Some manufacturers acknowledge problems such as this and may offer assistance.

Toshiba 46h84 rear projection shutting down


I have a Toshiba 46h84 with similar problem that needs a new green crt. Mine does not have a cooling fan. I don't know if having a cooling fan would help the problem, but mine didn't come with one. There are rear projection TV's that have bulbs in them that require a fan. This particular model uses a red, a green, and a blue crt to generate the picture and probably doesn't need one.

SCreen turns red then shuts off


The 46H84 has 3 CRTs instead of a lamp. Red, Green and Blue. Your red CRT is shorting out shutting down the set.Here is how you test that theory. Remove the speaker grille, there will be an access panel behind the grille remove that and you will see the CRTs red is usually on the left. hit the power momentarally to locate which tube is red. then power down and unplug the power cord. Carefully remove the tubes Circuit board. ( you may have to carefully slice the glob of silicone applied at the factory to get the circuit board off) Once you have the circuit board off the Red CRT make sure it isnt touching anything and try powering up the set. If the set stays on and the other 2 CRTs light up. That tells you the RED crt is shorted and thats whats shutting your set down. Let me know if I can assist you further.
