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.

Lines on my toshiba model 46h84 projection tv has lines on screen until it warms up What could be causing thi. Once it warms up the picture is fine. which takes about 10 minutes


I have the same issue with mine which started a couple of months ago and has only gotten worse. I've been googling this and found that it could be the convergence module(s), apparently there are 1-3 of them and ALL of them should be replaced. I'm not sure on a cost, but I'm guessing it won't be cheap. I think we are just going to get a new tv, with the prices for LCD's coming down this will probably be a cheaper option. Good Luck :)

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.

Smudge marks???


If they are grease marks you can use a warm water a soft cloth like a t-shirt and little dish washing liquid. Gentley wipe the area only stroking down or up--- NEVER SIDE TO SIDE---. Have a dry cloth ready if you drip water down the screen. Now if those are scuff marks, your done, they cannot be removed. They are like the old record albums with the grooves, once the grooves get distorted that's it. Good luck.
