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.

The problem is you convergence IC's. STK392-110. If you are not experienced I would contact a tech to do this work. Repair costs should be 200-400 depending where you live.

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.

Blue crt assmbly maybe?


its very possible that the blue CRT is horting the set out. Heres how you can test it. Remove the speaker grille and access panel behind the grille and you will see the crts. remove the blue crt circuit board from the end of the blue crt and make sure it isnt touching anything then try powering up the set if it doesnt shut down then you have found the problem and you will need a new crt. or you can switch the blue circuit with the green and try it iwth the blue on green and the green on the blue then if the screen turns green before shutting down you will know that its a problem in the blue drive circuit and not the crt. lety me know if you need further assistance.

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.
