Question about Toshiba 46HM95 46" HDTV
The background flickers. Sometimes the picture quality seems poor. Usually reds and oranges. The flickering is predominent in black backgrounds. Any help would be appreciated. This problem is driving my pregnant wife crazy. Thanks.
Take out the lamp and clean it. Look inside where the lamp was and you will see a thin peice of coloured plastic (colour wheel). Vacuum that plastic and all around it but don't touch it. This solution worked for me, and now my TV is as good as new.

WOW! I fixed the flickering and the color blur with the info I got here. I removed the lamp and vacuumed it thoroughly. I also carefully vacuumed the lamp housing area and stuck the vacuum tip as close to the color wheel as possible. While I had the back cover off I vacuumed every accesible area.My TV is like new again. I'm so happy! I feel like I got a new TV. The picture was horrible before. All it took was this simple cleaning. We almost ordered a new lamp which would have cost us $300. Our TV is a Toshiba 62". I think this will work for every other similiar TV. I will do this cleaning on a routine basis now. Thanks everyone!!!!

Well folks I had some issues with the tv (46hm95) as well. Oranges and reds seemed to blur and become almost "blocky" or looked like large pixels. Facials seemed way off especially if someone had blotchy skin. I took out my bulb and shone a light into the color wheel assembly. Much to my dismay I saw that the color wheel was coated with a thick layer of caked on dust. I took the tv all apart (this was a project) and cleaned the color wheel with a qtip and windex. I aslo cleaned the projection lens which had accumulated dust. I got it back together and the tv is like new. I was missing out on so much color and detail, as the dust built up gradually over time I never noticed how bad it had gotten. I had also had some cloudy spots on the screen before this and it remedied that as well. I would highly recommend doing this to get the performance out of the tv, but if you are not mechanically inclined be very careful.

Clean everything inside the lamp housing. If possible, take the whole thing apart a clean it thoroughly. I'm pretty sure the image will improved a lot, at least the brightness. If he resolution looks not so good, the you have to make some adjustments to the color wheel delay. In order to do this you have to be in service mode...

I had the same diagnosis. It was acting the same with weird image flickering. It was in a rather dusty environment. I took it to the repair shop and the guy explained that toshiba does not stock the color wheel as a separate part, You need the entire assembly, which is $445 from Toshiba. The rest is labor. I'm a tech, but never worked on projectors. I figured I bought the thing for $1499 just about 3 years ago. I've been through 3 bulbs and now this. I removed the brand new bulb from the unit and had e-waste haul it away. I bought a nice 47" LCD with the money I would have spent to fix it. If I sell the bulb, I can break even. I already am in a class action about the bulb fiasco, but now this. I'm finished buying Toshiba products.

I agree with dhlg's comment. My husband and I took out the lamp, cleaned all inside (without touching the color wheel) and it works like new again! Very simple solution and I am so glad I stumbled upon his suggestion of simple cleaning because it worked.....No money necessary! Try it before you spend money to fix something not broken!

My toshiba did the same thing. I took it in and its the light engine. Which cost around 700$ for parts and labor. How ever the part is on back order and they don't know when they will be getting them in. I have only had my set 2 years a month ago. Called toshiba and said sorry but there is nothing we can do. The repair guy said not to spend the money and buy another tv. Because this brand of tv is being known for having this problem. Toshiba sucks!!!! If anyone hears of a lawsuit count me in .

We have had our Toshiba DLP for 8 years and have replaced the lamp only twice. I believe that it is critical not to touch the lamp as the oils on your skin will drastically reduce the performance and life of the lamp. We also disassembled and thoroughly (and carefully) cleaned the lens with a lint-free cloth and other areas with a vaccuum being very careful not to touch anything. I believe you are not to use any harsh cleaners, such as products containing ammonia. We have had several Toshiba products and absolutely love them. Some time ago our Toshiba (a previous one) had been struck by lightning and was in a local black-hole repair shop. We got tired of waiting for this repair man to "get the part in", so we called Toshiba and they overnighted to part and then called us a couple days later to make sure that we had our repaired Toshiba product back. Toshiba is interested in knowing if one of their "certified Toshiba repair shops" are not providing necessary service.

I have replace the lamp for my 65 inches Toshiba TV but the picture is now flickering and little blury What is the solution?

Strangely, After re-inserting the lamp and vaccuuming things have gotten better. I wonder if it is heat related. Sometimes I occasionally still have the issue but it is not consistent. If I switch TV stations between SD and HD that will almost always fix the issue.
